| Nature of Business | |
| Nature Of Business [Text Block] | Nature of Business RPX Corporation (also referred to herein as “RPX” or the “Company”) helps companies reduce patent-related risk and expense by providing a subscription-based patent risk management solution that facilitates more efficient exchanges of value between owners and users of patents compared to transactions driven by actual or threatened litigation. The core of the Company’s solution is defensive patent aggregation, in which it acquires patents or licenses to patents that are being or may be asserted against the Company’s current or prospective clients. The Company may occasionally enter into agreements to acquire covenants not to sue in order to further mitigate its clients’ litigation risk. The acquired patents, licenses to patents and agreements for covenants not to sue are collectively referred to as “patent assets.” The Company’s clients pay an annual subscription fee and in return, receive a license from the Company to substantially all of its patent assets and access to its proprietary patent market intelligence and data. In addition to the Company’s core solution, during the year ended December 31, 2012, the Company began underwriting patent infringement liability insurance policies to insure against certain costs of litigation from non-practicing entities (“NPEs”). The effect of the insurance policies that have been issued has been insignificant to the Company’s results of operations or financial condition for the year ended December 31, 2012. |

| Basis of Presentation and Significant Accounting Policies | |||||||||||||||||||||||||||||||||||||||||||||||||||||
| Basis Of Presentation And Significant Accounting Policies [Text Block] | Basis of Presentation and Significant Accounting Policies Basis of Presentation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of RPX and its wholly owned subsidiaries. All intercompany transactions have been eliminated. Management performed an evaluation of the Company’s activities through the date of filing of this Annual Report on Form 10-K, and has concluded that there are no subsequent events requiring disclosure through that date. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, contingent assets and liabilities, and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of revenues and expenses during the reporting period covered by the consolidated financial statements and accompanying notes. The Company bases its estimates on various factors and information which may include, but are not limited to, history and prior experience, expected future results, new related events and current economic conditions, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates. Significant estimates and assumptions made by management include the determination of:
Revenue Recognition The Company recognizes revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition (“ASC 605”) and related authoritative guidance. The primary source of the Company’s revenue is fees paid by its clients under subscription agreements. The Company believes that its patent risk management solution comprises a single deliverable and thus the Company recognizes each subscription fee ratably over the period for which the fee applies. Revenue is recognized net of any discounts or other contractual incentives. The Company starts recognizing revenue when all of the following criteria have been met:
In some limited instances, the subscription agreement includes a contingency clause, giving one or both parties an option to terminate the agreement and receive a full refund if contingencies are not resolved within a defined time period. In those instances, revenue will not be recognized until all contingencies have been removed. The revenue earned during the period between the effective date of the agreement and the contingency removal date is recognized on the contingency removal date. Thereafter, revenue is recognized ratably over the remaining subscription term. The Company’s clients generally receive a term license to, and a release from, all prior damages associated with patent assets in the Company’s portfolio. The term license to each patent asset converts to a perpetual license at the end of a contractually specified vesting period, provided that the client is a member at such time. The Company does not view the conversion from term license to perpetual license to be a separate deliverable in its arrangements with its clients because the utility of, access to and freedom to practice the inventions covered by the patent asset is no different between a term and perpetual license. In some instances, the Company accepts a payment from a client to finance part or all of an acquisition. The Company refers to such transactions as structured acquisitions. Structured acquisitions where the Company accepts payment from several clients is referred to as a syndicated acquisition. The accounting for structured acquisitions is complex and often requires judgments on the part of management as to the appropriate accounting treatment. In accordance with ASC 605-45, Revenue Recognition: Principal Agent Considerations, in instances where the Company substantively acts as an agent to acquire patent rights from a seller on behalf of clients who are paying for such rights separately from their subscription agreements, the Company may treat the client payments on a net basis. When treated on a net basis, there may be little or no revenue recognized for such contributions, and the basis of the acquired patent rights may exclude the amounts paid by the contributing client based on the Company’s determination that it is not the principal in these transactions. In these situations, where the Company substantively acts as an agent, the contributing clients are typically defendants in an active or threatened patent infringement litigation filed by the owner of a patent. The Company’s involvement is to assist its clients to secure a dismissal from litigation and a license to the underlying patents. Key indicators evaluated to reach the determination that the Company is not the principal in the transaction include, among others:
In certain structured transactions, the Company may recognize revenue upon the sale of licenses to specific patent assets and/or upon completion of the rendering of advisory services. Accounting for Payments to Clients The Company occasionally agrees to provide payments, discounts or other contractual incentives to clients in exchange for specified consideration. The Company accounts for such contract provisions in accordance with ASC 605-50, Revenue Recognition: Customer Payments and Incentives, which requires the Company to offset the amount of the payment, discount or other contractual incentive against revenue if the Company is unable to demonstrate both receipt of an identifiable benefit and determine the fair value of the benefit received. Deferred Revenue The Company generally invoices its clients upon execution of a new agreement and prior to any payment date for existing agreements. The Company records the amount of fees billed as deferred revenue and recognizes such amounts as revenue ratably over the period for which they apply. The Company generally records deferred revenue when it has the legal right to bill amounts owed. In the rare instance where a term has commenced but the fees have not yet been invoiced, the Company records an unbilled receivable. Deferred revenue that will be recognized during the succeeding 12-month period from the respective balance sheet date is recorded as deferred revenue, current, and the remaining portion is recorded as non-current. Accounts Receivable Accounts receivable primarily includes amounts billed to clients under their subscription agreements. The majority of the Company’s clients are well-established operating companies with investment-grade credit. For the periods ended December 31, 2012 and 2011, the Company has not incurred any losses on its accounts receivable. Based upon its historical collections experience and specific client information, the Company has determined that no allowance for doubtful accounts was required at either December 31, 2012 or 2011. Concentration of Risk The Company is subject to concentrations of credit risk principally attributable to cash, cash equivalents, investments, accounts receivable and other receivables. The Company’s cash balances (both, restricted and non-restricted) deposited in U.S. banks are non-interest bearing and are insured up to the Federal Deposit Insurance Corporation (“FDIC”) limits. Cash equivalents primarily consist of institutional money market funds, U.S. government and agency securities, municipal bonds and commercial paper denominated primarily in U.S. dollars. Investment policies have been implemented that limit purchases of debt securities to investment-grade securities. Credit risk with respect to accounts and other receivables is generally mitigated by short collection periods and/or subscription agreements that provide for payments in advance of the rendering of services. Three clients accounted for 22%, 18% and 13% of accounts receivable at December 31, 2012. Four clients accounted for 26%, 20%, 14% and 12% of accounts receivable at December 31, 2011. Two clients, neither of which was represented in the accounts receivable balance at December 31, 2012, accounted for 62% and 38% of other receivables at December 31, 2012. No client accounted for more than 10% of subscription fee revenue in any of the years ended December 31, 2012, 2011 or 2010. Fair Value Measurements The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, which are required to be recorded at fair value, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as risks inherent in valuation techniques, transfer restrictions and credit risk. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 – Valuations based on quoted prices in active markets for identical assets or liabilities and readily accessible by the Company at the reporting date. Level 2 – Valuations based on inputs other than quoted prices included within Level 1 that are observable for assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 – Valuations based on inputs that are unobservable. The carrying amounts of the Company’s financial instruments, which include cash equivalents, investments, accounts receivable, other receivables and accounts payable, approximate their fair values due to their short maturities. Based on borrowing rates currently available to the Company for notes payable and other deferred payment obligations with similar terms, and considering the Company’s credit risk, the carrying value of deferred payment obligations approximates fair value. Cash and Cash Equivalents The Company’s cash and cash equivalents principally consist of institutional money market funds, corporate bonds, municipal bonds and commercial paper denominated primarily in U.S. dollars. Cash equivalents are highly liquid, short-term investments having an original maturity of 90 days or less that are readily convertible to known amounts of cash. Short-Term Investments The Company holds short-term investments in U.S. government and agency securities, commercial paper corporate bonds, and municipal bonds with maturities greater than 90 days. The Company considers its investments as available to support current operations. As a result, the Company classifies its investments including those with stated maturities beyond twelve months, as current assets in the accompanying consolidated balance sheets. The Company classifies these securities as “available-for-sale” and carries them at fair value on the consolidated balance sheets. Unrealized gains or losses are recorded, net of estimated taxes, in accumulated other comprehensive income (loss), a component of stockholders’ equity. Realized gains and losses are recognized upon sale. The specific identification method is used to determine the cost basis of fixed income securities sold. The Company periodically evaluates its investments for impairment due to declines in market value considered to be “other-than-temporary.” This evaluation consists of several qualitative and quantitative factors, including the Company’s ability and intent to hold the investment until a forecasted recovery occurs, as well as any decline in the investment quality of the security and the severity and duration of the unrealized loss. In the event of a determination that a decline in market value is other-than-temporary, the Company will recognize an impairment loss, and a new cost basis in the investment will be established. To date, the Company has not recorded any impairment related to its investments in its consolidated statements of operations. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using a straight-line method over the estimated useful lives of the related assets, which is generally three to five years. Maintenance and repairs are charged to expense as incurred, and improvements and betterments are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the consolidated balance sheet and any resulting gain or loss is reflected in the consolidated statement of operations in the period realized. Leasehold improvements are amortized on a straight-line basis over the term of the lease, or the useful life of the assets, whichever is shorter. Internal-Use Software and Website Development Costs The Company capitalizes development costs related to internal-use software and its website and records such amounts as property and equipment, net, on its consolidated balance sheets. These costs include personnel and personnel-related expenses and consultant fees incurred during the application development stages of the project. Costs related to preliminary project activities, minor enhancement and maintenance, and post implementation activities are expensed as incurred. Internal-use software is amortized on a straight-line basis over its useful life, which is generally three years, beginning on the date the software is placed into service. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. During the years ended December 31, 2012 and 2011, the Company capitalized $1.9 million and $1.2 million, respectively, of internal-use software and website development costs. Amortization of internal-use software was $0.8 million, $0.1 million and nil for the years ended December 31, 2012, 2011 and 2010, respectively. Patent Assets The Company generally acquires patent assets from third parties using cash and contractually deferred payments. Patent assets are recorded at fair value. The fair value of the assets acquired is generally based on the fair value of the consideration exchanged. The asset value includes the cost of legal and other fees associated with the acquisition of the assets. Costs incurred to maintain and prosecute patents and patent applications are expensed as incurred. Because each client generally receives a license to the vast majority of the Company’s patent assets, the Company is unable to reliably determine the pattern over which its patent assets are consumed. As a result, the Company amortizes each patent asset on a straight-line basis. The amortization period is equal to the asset’s estimated economic useful life. Estimating the economic useful life of patent assets requires significant management judgment. The Company considers various factors in estimating the economic useful lives of its patent assets, including the remaining statutory life of the underlying patents, the applicability of the assets to future clients, the vesting period for current clients to obtain perpetual licenses to such patent assets, any contractual commitments by clients that are related to such patent assets, its estimate of the period of time during which the Company may sign subscription agreements with prospective clients that may find relevance in the patent assets, the vesting period for which such clients earn the right to a perpetual license in the asset and the remaining contractual term of the Company’s existing clients at the time of acquisition. In certain instances, where the Company acquires patent assets and secures related client committed cash flows that extend beyond the statutory life of the underlying patents, the useful life may extend beyond the statutory life of the patents. As of December 31, 2012, the estimated economic useful life of the Company’s patent assets generally ranged from 24 to 60 months, and the weighted-average estimated economic useful life at the time of acquisition, excluding fully amortized patent assets, was 46 months. The Company periodically evaluates whether events and circumstances have occurred that may warrant a revision to the remaining estimated useful life of its patent assets. In instances where the Company sells patent assets, the amount of consideration received is compared to the asset’s carrying value to determine and recognize a gain or loss. Patent Asset Financing The Company may use seller financing in the form of notes payable or contractually deferred payments for acquisitions of patent assets. In such cases, the acquired assets may serve as collateral or be otherwise encumbered during the term of the financing. Contractual amounts owed under such financing arrangements are recorded at fair value using a market rate of interest. If such financing arrangements do not have a stated interest rate, the Company imputes interest at a market rate (thereby discounting the future payments to present value) to account for the time-value-of-money component of the asset purchase. The difference between the contractual amounts due and the present value is recognized as interest expense over the period the payments are due. The Company records a corresponding patent asset for any such contractual obligations. Amounts due within approximately one year of the date of the acquisition under financing arrangements with no stated interest rate are recorded at face value. The interest component is imputed, if necessary, at the time of acquisition by using the then-current market yield of an index of comparable maturity securities with a credit rating comparable to that of the Company. Impairment of Long-Lived Assets The Company assesses the recoverability of its long-lived assets, which includes patent assets, other intangible assets and property and equipment, when events or changes in circumstances indicate their carrying value may not be recoverable. Such events or changes in circumstances may include: a significant adverse change in the extent or manner in which a long-lived asset is being used, a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development of a long-lived asset, current or future operating or cash flow losses that demonstrate continuing losses associated with the use of a long-lived asset or a current expectation that, more-likely-than-not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The Company licenses the portfolio of patent assets to all of its clients and thus views these assets as a single asset group. The Company assesses recoverability of a long-lived asset by determining whether the carrying value of these assets can be recovered through projected undiscounted cash flows. If the carrying value of the assets exceeds the forecasted undiscounted cash flows, an impairment loss is recognized, and is recorded as the amount by which the carrying value exceeds the estimated fair value. An impairment loss is charged to operations in the period in which management determines such impairment. To date, there have been no impairments of long-lived assets identified. Assets Held for Sale The Company classifies assets as held for sale when certain criteria are met, including: management’s commitment to a plan to sell the assets; the availability of the assets for immediate sale in their present condition; whether an active program to locate buyers and other actions to sell the assets has been initiated; whether the sale of the assets is probable and their transfer is expected to qualify for recognition as a completed sale within one year; whether the assets are being marketed at reasonable prices in relation to their fair value; and how likely it is that significant changes will be made to the plan to sell the assets. There were no assets held for sale at December 31, 2012 or 2011. Goodwill Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company evaluates goodwill for impairment on an annual basis during its third fiscal quarter or whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. In accordance with ASC Topic 350, Intangibles - Goodwill & Other (“ASC Topic 350”), the goodwill impairment test consists of a two-step process, if necessary. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC Topic 350. The more likely than not threshold is defined as having a likelihood of more than 50 percent. If, after assessing the totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary and goodwill is considered to be unimpaired. However, if based on the Company’s qualitative assessment, it concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company will proceed with performing the two-step process. The first step of the impairment test involves comparing the fair value of the reporting unit to its net book value, including goodwill. As of December 31, 2012, the Company had one reporting unit. If the net book value exceeds its fair value, then the Company would perform the second step of the goodwill impairment test to determine the amount of the impairment loss. The impairment loss would be calculated by comparing the implied fair value of the Company to its net book value. In calculating the implied fair value of the Company’s goodwill, the fair value of the Company would be allocated to all of the other assets and liabilities based on their fair values. The excess of the fair value of the Company over the amount assigned to its other assets and liabilities is the implied fair value of goodwill. An impairment loss would be recognized when the carrying amount of goodwill exceeds its implied fair value. There have been no impairments of goodwill recorded in the Company’s consolidated statements of operations through December 31, 2012. Intangible Assets, Net Intangible assets, net primarily consists of intangible assets acquired from other companies as a result of acquisitions. Such assets are capitalized and amortized on a straight-line basis over their estimated useful lives. Intangible assets, net excludes patent related intangible assets, which are recorded within patent assets, net in the accompanying consolidated balance sheets. Advertising Costs The Company expenses advertising costs as they are incurred. Advertising expenses were not material for any of the periods presented. Foreign Currency Accounting The Company’s subscription agreements are denominated in U.S. dollars; however, several of the Company’s clients report revenue and operating income in foreign currencies. As subscription fees are determined using the reported revenue and operating income of the Company’s clients, a significant sustained change in exchange rates could result in a change in subscription fees from clients reporting revenue and operating income in a currency other than the U.S. dollar. The Company’s expenses are incurred primarily in the United States, with a small portion of expenses incurred and denominated in Japanese Yen and the Euro. The functional currency of the Company’s international subsidiaries is the U.S. dollar. Monetary assets and liabilities are remeasured using the current exchange rate at the balance sheet date. Non-monetary assets and liabilities and capital accounts are remeasured using historical exchange rates. Expenses are remeasured using the average exchange rates in effect during the period. Foreign currency exchange gains and losses, which have not been material for any periods presented, are included in the consolidated statements of operations under other income (expense), net. Income Taxes The Company accounts for income taxes using an asset and liability approach, which requires the recognition of deferred tax assets or liabilities for the tax-effected temporary differences between the financial reporting and tax bases of its assets and liabilities and for net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefits that, based on available evidence, are not expected to be realized. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income, and to the extent the Company believes that recovery is not likely, the Company establishes a valuation allowance. Judgment is required in determining the Company’s provision for income taxes, deferred tax assets, and liabilities and any valuation allowance recorded against the net deferred tax assets. The Company had not applied a valuation allowance against its deferred tax balances for the years ended December 31, 2012 or 2011. The calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across its global operations. ASC 740 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. ASC 740 also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company recognizes tax liabilities in accordance with ASC 740 and adjusts these liabilities when its judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from its current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information is available. Stock-Based Compensation The Company accounts for stock-based compensation under ASC 718, Compensation-Stock Compensation (“ASC 718”). ASC 718 requires that compensation expense for all equity-settled awards made to employees and directors be measured and recognized based on estimated grant date fair values. These equity awards include stock options and restricted stock units (“RSUs”). Stock-based compensation expense for RSUs granted to employees and directors is measured based on the fair market value of the Company’s common stock on the date of grant. Stock-based compensation expense for stock options awarded to employees and directors is estimated based on the fair value of each stock option using an option pricing model. The value of awards expected to vest is recognized as expense on a straight-line basis over the requisite service period. The Company accounts for stock-based compensation for equity-settled awards issued to non-employees in exchange for goods and services under ASC 505-50, Equity-Based Payments to Non-Employees (“ASC 505-50”). ASC 505-50 requires that equity awards issued to non-employees be measured at the fair value as of the date at which either the commitment for performance by the non-employee to earn the award is reached or the date the non-employee’s performance is complete. Until that point is reached, the award must be revalued at each reporting period with the true-up to expense recorded in the then current period earnings. The value of the award is recognized as an expense over the requisite service period. The Company selected the Black-Scholes option pricing model as the most appropriate method for determining the estimated fair value for stock options. The Black-Scholes model requires the use of highly subjective and complex assumptions which determine the fair value of stock-based awards, including the option’s expected term and the price volatility of the underlying stock. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. See Note 15. Business Combinations The Company applies the provisions of ASC 805, Business Combinations (“ASC 805”), in the accounting for its business acquisitions. ASC 805 requires companies to recognize goodwill separately from the assets acquired and liabilities assumed, which are valued at their acquisition date fair values. Goodwill as of the acquisition date represents the excess of the purchase price over the fair values of the assets acquired and the liabilities assumed. The Company uses significant estimates and assumptions, including fair value estimates, to determine fair value of assets acquired and liabilities assumed and when applicable the related useful lives of the acquired assets, as of the business combination date. When those estimates are provisional, the Company refines them as necessary during the measurement period. The measurement period is the period after the acquisition date, not to exceed one year, in which the Company may gather new information about facts and circumstances that existed as of the acquisition date to adjust the provisional amounts recognized. Measurement period adjustments are applied retrospectively, if material. All other adjustments are recorded to the consolidated statements of operations. Recently Issued Accounting Standards In February 2013, the FASB issued Accounting Standards Update (“ASU”) 2013-02, Reporting of Amounts of Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”), which amends Comprehensive Income (Topic 220) in the ASC. These amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amendments in ASU 2013-02 will be effective for fiscal periods beginning after December 15, 2012. The adoption of ASU 2013-02 is not expected to have a material impact on the Company’s financial position or results of operations. In October 2012, the FASB issued ASU 2012-04, Technical Corrections and Improvements (“ASU 2012-04”), which amends a wide range of topics in the ASC. These amendments include technical corrections and improvements to the ASC and conforming amendments related to fair value measurements. The amendments in ASU 2012-04 will be effective for fiscal periods beginning after December 15, 2012. The adoption of ASU 2012-04 is not expected to have a material impact on the Company’s financial position or results of operations. In July 2012, the FASB issued ASU 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment (“ASU 2012-02”), which amends ASU 2011-08, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment and permits an entity to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with Subtopic 350-30, Intangibles - Goodwill and Other - General Intangibles Other than Goodwill. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted, including for annual and interim impairment tests performed as of a date before July 27, 2012, if a public entity’s financial statements for the most recent annual or interim period have not yet been issued or, for nonpublic entities, have not yet been made available for issuance. The adoption of ASU 2012-02 is not expected to have a material impact on the Company’s financial position or results of operations. Recently Adopted Accounting Standards In August 2012, the FASB issued ASU 2012-03, Technical Amendments and Corrections to SEC Sections: Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 114 (“SAB 114”), Technical Amendments Pursuant to SEC Release No. 33-9250, and Corrections Related to FASB Accounting Standards Update 2010-22, which amends various SEC paragraphs pursuant to the issuance of SAB114. This ASU became effective upon issuance, and the adoption of this ASU had no impact on the Company’s financial position or results of operations. In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income (“ASU 2011-05”), which requires companies to present the components of net income and other comprehensive income either in a single continuous statement or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. ASU 2011-05 does not change the items which must be reported in other comprehensive income, how such items are measured or when they must be reclassified to net income. Additionally, ASU 2011-05 does not affect the calculation or reporting of earnings per share. On January 1, 2012, the Company adopted this ASU and elected the two-statement presentation option. Other than the change in presentation, the adoption of this ASU had no impact on the Company’s financial position or results of operations. |

| Net Income Available to Common Stockholders [Text Block] | Net Income Available to Common Stockholders Basic and diluted net income per share available to common stockholders are presented in conformity with the two-class method required for participating securities. Upon the Company’s initial public offering in May 2011, all shares of the Company’s redeemable convertible preferred stock were converted to common stock. Prior to the initial public offering, holders of shares of Series A, Series A-1, Series B and Series C redeemable convertible preferred stock were each entitled to receive 8% per annum non-cumulative dividends, payable prior and in preference to any dividends on common stock. In addition, the holders of restricted common stock are entitled to receive non-forfeitable dividends if declared. Under the two-class method, basic net income per share available to common stockholders is computed by dividing the net income available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Net income available to common stockholders is determined by allocating undistributed earnings, calculated as net income less current period shares of Series A, Series A-1, Series B and Series C redeemable convertible preferred stock non-cumulative dividends, among common stockholders, restricted stockholders and Series A, Series A-1, Series B and Series C redeemable convertible preferred stockholders. Diluted net income per share available to common stockholders is computed by using the weighted-average number of shares of common stock outstanding, including potential dilutive shares of common stock, assuming the dilutive effect of outstanding stock options and restricted stock units using the treasury stock method. The following table presents the calculation of basic and diluted net income per share available to common stockholders:
For the years ended December 31, 2012, 2011 and 2010 the following securities were not included in the calculation of diluted shares outstanding, as the effect would have been anti-dilutive (in thousands):

| Patent Assets, Net [Text Block] | Patent Assets, Net Patent assets, net consisted of the following (in thousands):
The Company’s acquired patent assets relate to technologies used or supplied by companies in a variety of market sectors, including consumer electronics, e-commerce, financial services, media distribution, mobile communications, networking, semiconductors, and software. The Company amortizes each acquired portfolio of patent assets on a straight-line basis over its estimated economic useful life. As of December 31, 2012, the estimated economic useful lives of the Company’s patent assets generally ranged from 24 to 60 months. As of December 31, 2012, the weighted-average estimated economic useful life at the time of acquisition, excluding fully amortized patent assets, was 46 months. The following table summarizes the expected future annual amortization expense of patent assets as of December 31, 2012 (in thousands):
Amortization expense was $80.4 million, $62.3 million and $42.9 million for the years ended December 31, 2012, 2011 and 2010, respectively. Structured Acquisitions Structured acquisitions are transactions involving patent assets that may cost more than the Company is prepared to spend with its own capital resources or that are relevant only to a very small number of clients. In such transactions, the Company may work to acquire these assets with financial assistance from the particular clients against whom they are being or may be asserted. Such clients either pay amounts separate from their subscription fee or, less frequently, lend the Company funds to be used in the transaction. As discussed in the revenue recognition policy in Note 2, the Company may treat the contributions from such clients as revenue on a gross or net basis depending on the specific facts and circumstances of the transaction. In the event that such contributions are recognized on a net basis, the Company will only capitalize the acquired asset that relates to its non-contributing clients. As a result, in such situations the cost basis of the acquired patent rights excludes the amounts paid by the contributing clients. |

| Business Combinations [Text Block] | Business Combinations On March 30, 2012, the Company entered into a number of agreements with Digitude Innovations, LLC (“Digitude”), Preservation Technologies LLC (“Preservation”), and Robert and Susan Kramer (collectively, the “Agreements”). The Agreements were subject to closing conditions that were satisfied on April 19, 2012. Pursuant to the Agreements, the Company paid $45.8 million and acquired, among other things, (i) certain patents, patent rights and a covenant not to sue and (ii) all of the issued and outstanding membership interests in Altitude Capital Management LLC. The following table summarizes the estimated fair values of the components of identifiable intangible assets acquired and liabilities assumed as of the date of acquisition (in thousands):
The fair values assigned to identifiable intangible assets acquired and liabilities assumed are based on management’s estimates and assumptions. The excess of purchase consideration over the fair value of identifiable intangible assets acquired and liabilities assumed was recorded as goodwill. Patent assets represent the ownership or rights to more than 500 U.S. (and more than 50 non-U.S.) patents that were held by Digitude, certain sub-license rights to patents licensed exclusively by Preservation and a covenant not to sue entered into with Robert Kramer. The patent assets have an estimated weighted-average life of 55 months. The portfolios acquired cover a broad range of technologies including mobile handsets, TVs, cameras, PCs, media players, content delivery, video-on-demand, internet streaming, and enterprise networks and have increased the Company’s total portfolio of patent assets by more than 30%. Proprietary data and models primarily consist of specialized data and processes related to patent analysis and valuation methodologies. These assets have an estimated weighted-average useful life of 48 months. Trademark represents the value of the Altitude Capital trademark with an estimated useful life of 48 months. The covenant not to compete represents certain restrictive covenants pursuant to which Robert Kramer has agreed to refrain from competing against any of the Company’s lines of business for a period of 21 months. Goodwill recorded as a result of this acquisition is primarily related to enhancing the Company’s position as a market leader capable of executing highly complex structured acquisitions. The value of goodwill is deductible for tax purposes. Under ASC 805-10, acquisition-related costs are not included as a component of consideration transferred but are required to be expensed as incurred. Acquisition-related costs were $0.6 million for the year ended December 31, 2012 and are included in selling, general and administrative expenses. Pro forma results of operations reflecting the acquisition have not been presented because the effect of the acquisition is not material to the Company’s results of operations. |

| Deferred Payment Obligations [Text Block] | Deferred Payment Obligations On July 6, 2009, the Company entered into an agreement to purchase certain patent assets for a total of $4.4 million. Under the terms of the agreement, the Company paid $1.1 million in cash at signing, with a remaining non-interest bearing contract obligation of $3.3 million due in three equal installments in July of each of 2010, 2011 and 2012. The contract obligation was recorded at fair value utilizing the imputed interest rate method. Interest was imputed using a rate of 10.2% per annum, which represented the Company’s estimated market borrowing rate as of the initial transaction date. As of December 31, 2012 and 2011, the remaining unpaid principal balance associated with the obligation was nil and $1.1 million, respectively. On January 26, 2009, the Company entered into an agreement to acquire certain patent assets for a total of $12.0 million.

| Commitments And Contingencies [Text Block] | Commitments and Contingencies Operating Lease Commitments The Company leases its facilities under non-cancelable lease agreements. The Company’s operating lease obligations have increased from those as of December 31, 2011 as a result of the following agreement entered into during the year ended December 31, 2012. In March 2012, the Company entered into an amended lease agreement related to its San Francisco, California office space. The amendment, which takes effect on May 1, 2013, will increase the rentable space to approximately 67,000 total square feet and extend the term through October 2019. The monthly base rent payments pursuant to this lease will initially be approximately $0.3 million per month, increasing to approximately $0.4 million per month. Rent expense related to non-cancelable operating leases was $2.4 million, $1.7 million and $0.7 million for the years ended December 31, 2012, 2011 and 2010, respectively. The aggregate future non-cancelable minimum lease payments for the Company’s operating leases as of December 31, 2012 are as follows:
Litigation From time to time, the Company may be a party to various litigation claims in the normal course of business. Legal fees and other costs associated with such actions are expensed as incurred. The Company assesses, in conjunction with its legal counsel, the need to record a liability for litigation or contingencies. A liability is recorded when and if it is determined that such a liability for litigation or contingencies is both probable and reasonably estimable. No liability for litigation or contingencies was recorded as of December 31, 2012 or 2011. In February 2013, Volkswagen Group of America, Inc. (“Volkswagen”) filed a third party complaint (the "Complaint") against the Company as part of an existing patent infringement lawsuit in the U.S. District Court for the Eastern District of Texas that was originally filed by Norman IP Holdings, LLC (“Norman”) and in which Volkswagen is a defendant. The Complaint relates to a patent license and acquisition transaction that the Company entered with Norman and Saxon in January 2010. The claims allege that the Company, together with Norman and Saxon Innovations, LLC (“Saxon”), violated federal antitrust law and Texas antitrust law. Volkswagen seeks declaratory relief, unspecified monetary damages, and injunctive relief. Because the case is at a very early stage, the Company is not currently able to determine whether there is a reasonable possibility that a loss has been incurred nor can it estimate the range of the potential loss that may result from this litigation. In March 2012, Cascades Computer Innovations LLC filed a lawsuit in U.S. District Court for the Northern District of California (the “Court”) against the Company and five of its clients (collectively the “Defendants”). The lawsuit alleges that the Defendants violated federal antitrust law, California antitrust law and California unfair competition law. The lawsuit claims that after the Company terminated its negotiations with the plaintiff to license certain patents held by the plaintiff, the Defendants violated the law by jointly refusing to negotiate or accept licenses under the plaintiff’s patents. The plaintiff seeks unspecified monetary damages and injunctive relief. In January 2013, the Court dismissed the complaint against the Defendants and granted the plaintiff leave to amend its complaint. In February 2013, the plaintiff filed an amended lawsuit alleging that the Defendants violated federal antitrust law, California antitrust law and California unfair competition law. The Company is not currently able to determine whether there is a reasonable possibility that a loss has been incurred, nor can it estimate the potential loss or range of the potential loss that may result from this litigation. Guarantees and Indemnifications The Company has, in connection with the sale of patent assets, agreed to indemnify and hold harmless the buyer of such patent assets for losses resulting from breaches of representations and warranties made by the Company. The terms of these indemnification agreements are generally perpetual. The maximum amount of potential future indemnification is unlimited. To date, the Company has not paid any amount to settle claims or defend lawsuits. The Company is unable to reasonably estimate the maximum amount that could be payable under these arrangements since these obligations are not capped but are conditional to the unique facts and circumstances involved. Accordingly, the Company had no liabilities recorded for these agreements as of December 31, 2012 or 2011. The Company has no reason to believe that there is any material liability related to such indemnification provisions. The Company does not indemnify its clients for patent infringement. In accordance with its amended and restated bylaws, the Company also indemnifies certain officers and employees for losses incurred in connection with actions, suits or proceedings threatened or brought against such officer or employee arising from his or her service to the Company as an officer or employee, subject to certain limitations. The term of the indemnification period is indefinite. The maximum amount of potential future indemnification is unspecified. The Company has no reason to believe that there is any material liability for actions, events or occurrences that have occurred to date. |

| Stock-Based Compensation [Text Block] | Stockholder’ Equity Common Stock As of December 31, 2012, under the Company’s amended and restated certificate of incorporation, the Company is authorized to issue 200 million shares of common stock with par value of $0.0001 per share. In connection with the issuance of the Series A redeemable convertible preferred stock in August 2008, the Company entered into a common stock repurchase agreement with its founders. The Company issued 9,999,998 shares of common stock to the Company’s founders in exchange for the assignment of intellectual property to the Company. The Company had the right to repurchase these shares of common stock upon the termination of a founder’s service to the Company. The repurchase rights lapsed over a four-year period, 25% on the first anniversary from the issuance date and thereafter ratably each month over the ensuing 36-month period. As of December 31, 2012 and 2011, nil and 1,666,666, respectively, of these shares were subject to repurchase. The value of common stock exchanged for the intellectual property was estimated to be $1.5 million based on the then-applicable common stock value of $0.145 per share. The assets received are recorded as intangible assets in the consolidated balance sheets and were being amortized over a four-year period. Preferred Stock As of December 31, 2012, under the Company’s amended and restated certificate of incorporation the Company is authorized to issue 10 million shares of preferred stock with a par value of $0.0001 per share. The Board of Directors is authorized to provide for the issuance of one or more series of preferred stock and to establish the powers, preferences and rights of the preferred shares. Equity Plans In February 2011, the Company’s Board of Directors adopted the 2011 Equity Incentive Plan (the “2011 Plan”), which became effective on the date of the Company’s initial public offering. The 2011 Plan provides for the issuance of incentive stock options, non-qualified stock options, stock appreciation rights, restricted shares of the Company’s common stock and stock units to employees, directors, and non-employees. The Board of Directors reserved 1,500,000 shares of common stock for future issuance under the 2011 Plan. In March 2012, the Company reserved an additional 2,457,269 shares of common stock for future issuance under the 2011 Plan. As of December 31, 2012, there were 3,023,027 shares available for grant under the 2011 Plan. In August 2008, the Company’s Board of Directors adopted the 2008 Plan (the “2008 Plan”) which provides for the issuance of incentive stock options, non-qualified stock options, as well as the direct award or sale of shares of common stock to employees, directors, and non-employees for up to 9,019,474 shares of common stock, as amended. No further awards have been made under the 2008 Plan; however, all awards outstanding under the 2008 Plan will continue to be governed by the existing terms. Under both the 2011 Plan and 2008 Plan, incentive stock options and non-qualified stock options are to be granted at a price that is not less than 100% of the fair value of the stock at the date of grant. Stock options granted to newly hired employees vest 25% on the first anniversary of the date of hire and ratably each month over the ensuing 36-month period. Stock options granted to existing employees generally vest ratably over the 48-months following the date of grant. Stock options are exercisable for a maximum period of 10 years after date of grant. Incentive stock options granted to stockholders who own more than 10% of the outstanding stock of the Company at the time of grant must be issued at an exercise price not to be less than 110% of the fair value of the stock on the date of grant. Restricted stock units granted to newly hired employees vest 25% on the first Company-established vest date after the first anniversary of the employee’s date of hire and ratably each quarter over the ensuing 12-quarter period. Restricted stock units granted to existing employees generally vest ratably each quarter over the 16 quarters following the date of grant. A summary of the Company’s activity under its equity award plans and related information is as follows (in thousands, except per share data):
The total intrinsic value for options exercised during the years ended December 31, 2012, 2011 and 2010 was $23.8 million, $19.0 million and $0.6 million, respectively. Restricted Stock Units The summary of restricted stock unit activity is as follows:
Stock-Based Compensation Related to Employees and Non-Employee Directors Stock-based compensation expense for employees and non-employee directors is based on the fair value of the award on the date of grant and is recognized on a straight-line basis over the requisite service period of the award. The Company estimates the fair value of stock options using the Black-Scholes option pricing model. Option valuation models, including the Black-Scholes option pricing model, require the input of various assumptions such as expected term, expected volatility and risk-free interest rates. Changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation expense is recognized. These inputs are subjective and generally require significant analysis and judgment to develop. For all stock options granted to date, the Company calculated the expected term using the SEC simplified method. The Company has limited information on its past volatility and has a limited operating history. Therefore, it has estimated the volatility data based on a study of publicly traded industry peer companies. For purposes of identifying these peer companies, the Company considered the industry, stage of development, size and financial leverage of potential comparable companies. The estimated forfeiture rate is derived primarily from our historical data, and the risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues similar in duration to the expected term of the Company’s stock options. The weighted-average assumptions used to estimate the fair value of stock options granted and the resulting fair values are as follows:
The fair value of restricted stock units granted to employees and non-employee directors is measured by reference to the fair value of the underlying shares on the date of grant. Stock-based compensation expense related to stock options granted to employees and non-employee directors was $7.9 million, $5.5 million and $1.0 million for the years ended December 31, 2012, 2011 and 2010, respectively. Stock-based compensation expense related to restricted stock units granted to employees and non-employee directors was $2.0 million, $0.4 million and nil for the years ended December 31, 2012, 2011 and 2010, respectively. As of December 31, 2012, there was $19.8 million and $7.4 million of unrecognized compensation cost related to stock options and restricted stock units, respectively, which was expected to be recognized over a weighted-average period of 2.7 years and 3.0 years, respectively. Future grants of equity awards will increase the amount of stock-based compensation expense to be recorded. Stock-Based Compensation Related to Non-Employees The Company periodically grants equity awards to non-employees in exchange for goods and services. During the year ended December 31, 2011, the Company issued 10,000 shares of common stock, 62,632 restricted stock units, and 75,000 stock options to non-employees in exchange for services. No awards were granted to non-employees in exchange for goods and services during the years ended December 31, 2012 and 2010. Stock-based compensation expense for non-employees is based on the fair value of the award on the measurement date, which is the earlier of the date by which the commitment for performance by the non-employee to earn the award is reached and the date on which the non-employee’s performance is complete. Each reporting period, the fair value of the unvested non-employee options or restricted stock units is revalued until the awards vest on the measurement date. Non-employee stock-based compensation expense related to stock options was $0.3 million, $0.9 million and $0.2 million for the years ended December 31, 2012, 2011 and 2010 , respectively. Non-employee stock-based compensation expense related to restricted stock units was $0.3 million, $0.2 million and nil for the years ended December 31, 2012, 2011 and 2010, respectively. |

| Income Taxes [Text Block] | Income Taxes Income before income tax provision consists of the following (in thousands):
The components of the provision for income taxes are as follows (in thousands):
Net deferred tax assets (liabilities) consist of the following (in thousands):
The following is a reconciliation of the statutory federal income tax to the Company’s effective tax (in thousands):
In assessing the realization of deferred tax assets, management considers whether it is more-likely-than-not that some portion or all of deferred assets will not be realized. The ultimate realization of the deferred tax asset is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based on the available objective evidence as of December 31, 2012, management believes it is more-likely-than-not that the U.S. net deferred tax asset will be fully realized. Accordingly, management has not applied a valuation allowance against its net deferred tax assets. As of December 31, 2012, the Company had state net operating loss carryforwards of $5.1 million available to reduce future taxable income, which will begin to expire in 2031. Internal Revenue Code Section 382 places a limitation (the Section 382 Limitation) on the amount of taxable income that can be offset by net operating loss carryforwards after a change in control (generally greater than 50% change in ownership) of a loss corporation. California has similar rules. Generally, after a change in control, a loss corporation cannot deduct operating loss carryforwards in excess of the Section 382 Limitation. Management has considered the impact of such limitation in determining the utilization of its operating loss carryforwards against taxable income in future periods. Deferred tax liabilities have not been recognized for undistributed earnings for foreign subsidiaries because it is management’s intention to permanently reinvest such undistributed earnings outside the U. S. Generally, such earnings are subject to potential foreign withholding tax and the U.S. tax upon remittance of dividends and under certain other circumstances. The amount of deferred tax liability for temporary differences related to investments in these non-U.S. subsidiaries are considered immaterial to the consolidated financial statements. Uncertain Tax Positions As of December 31, 2012, the Company’s total amount of unrecognized tax benefits was $1.1 million, all of which would impact the Company’s effective tax rate, if recognized. The following table summarizes the activity related to the Company’s unrecognized tax benefits (in thousands):
The Company does not believe it is reasonably possible that its unrecognized tax benefits will significantly change within the next twelve months. The Company’s policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. During the years ended December 31, 2012 and 2011, the Company recognized$0.1 million and nil respectively, of interest and penalties associated with unrecognized tax benefits. During the fourth quarter of 2012, the State of California Franchise Tax Board completed its examination of the Company’s California income tax returns for the 2009 and 2008 tax years. The examination did not have a material impact on the Company’s consolidated financial statements. During the first quarter of 2012, the Internal Revenue Service (“IRS”) completed its examination of the Company’s employment taxes for the 2010 and 2009 tax years and federal income tax returns for the 2009 and 2008 tax years. In addition, during the fourth quarter of 2011, the IRS issued a Notice of Proposed Adjustments for the 2008 and 2009 tax years with proposed adjustments and no assessment. The Company has agreed to the adjustments which have been approved by the IRS. The adjustments did not have a material impact on the Company’s consolidated financial statements. The 2008 through 2012 tax periods remain open to examination by the federal and most state tax authorities. For the Company’s foreign jurisdictions, the 2009 through 2012 tax years remain open to examination by their respective tax authorities. |

Dec. 31, 2012
|
|||||||||||||||||||||||||||||||||||||
| Basis of Presentation and Significant Accounting Policies (Abstract) | |||||||||||||||||||||||||||||||||||||
| Basis of Presentation [Policy Text Block] | Basis of Presentation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of RPX and its wholly owned subsidiaries. All intercompany transactions have been eliminated. Management performed an evaluation of the Company’s activities through the date of filing of this Annual Report on Form 10-K, and has concluded that there are no subsequent events requiring disclosure through that date. |
||||||||||||||||||||||||||||||||||||
| Use of Estimates [Policy Text Block] | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, contingent assets and liabilities, and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of revenues and expenses during the reporting period covered by the consolidated financial statements and accompanying notes. The Company bases its estimates on various factors and information which may include, but are not limited to, history and prior experience, expected future results, new related events and current economic conditions, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates. Significant estimates and assumptions made by management include the determination of:
|
||||||||||||||||||||||||||||||||||||
| Revenue Recognition [Policy Text Block] | Revenue Recognition The Company recognizes revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition (“ASC 605”) and related authoritative guidance. The primary source of the Company’s revenue is fees paid by its clients under subscription agreements. The Company believes that its patent risk management solution comprises a single deliverable and thus the Company recognizes each subscription fee ratably over the period for which the fee applies. Revenue is recognized net of any discounts or other contractual incentives. The Company starts recognizing revenue when all of the following criteria have been met:
In some limited instances, the subscription agreement includes a contingency clause, giving one or both parties an option to terminate the agreement and receive a full refund if contingencies are not resolved within a defined time period. In those instances, revenue will not be recognized until all contingencies have been removed. The revenue earned during the period between the effective date of the agreement and the contingency removal date is recognized on the contingency removal date. Thereafter, revenue is recognized ratably over the remaining subscription term. The Company’s clients generally receive a term license to, and a release from, all prior damages associated with patent assets in the Company’s portfolio. The term license to each patent asset converts to a perpetual license at the end of a contractually specified vesting period, provided that the client is a member at such time. The Company does not view the conversion from term license to perpetual license to be a separate deliverable in its arrangements with its clients because the utility of, access to and freedom to practice the inventions covered by the patent asset is no different between a term and perpetual license. In some instances, the Company accepts a payment from a client to finance part or all of an acquisition. The Company refers to such transactions as structured acquisitions. Structured acquisitions where the Company accepts payment from several clients is referred to as a syndicated acquisition. The accounting for structured acquisitions is complex and often requires judgments on the part of management as to the appropriate accounting treatment. In accordance with ASC 605-45, Revenue Recognition: Principal Agent Considerations, in instances where the Company substantively acts as an agent to acquire patent rights from a seller on behalf of clients who are paying for such rights separately from their subscription agreements, the Company may treat the client payments on a net basis. When treated on a net basis, there may be little or no revenue recognized for such contributions, and the basis of the acquired patent rights may exclude the amounts paid by the contributing client based on the Company’s determination that it is not the principal in these transactions. In these situations, where the Company substantively acts as an agent, the contributing clients are typically defendants in an active or threatened patent infringement litigation filed by the owner of a patent. The Company’s involvement is to assist its clients to secure a dismissal from litigation and a license to the underlying patents. Key indicators evaluated to reach the determination that the Company is not the principal in the transaction include, among others:
|
||||||||||||||||||||||||||||||||||||
| Accounting fo Payments to Clients [Policy Text Block] | Accounting for Payments to Clients The Company occasionally agrees to provide payments, discounts or other contractual incentives to clients in exchange for specified consideration. The Company accounts for such contract provisions in accordance with ASC 605-50, Revenue Recognition: Customer Payments and Incentives, which requires the Company to offset the amount of the payment, discount or other contractual incentive against revenue if the Company is unable to demonstrate both receipt of an identifiable benefit and determine the fair value of the benefit received. |
||||||||||||||||||||||||||||||||||||
| Deferred Revenue [Policy Text Block] | Deferred Revenue The Company generally invoices its clients upon execution of a new agreement and prior to any payment date for existing agreements. The Company records the amount of fees billed as deferred revenue and recognizes such amounts as revenue ratably over the period for which they apply. The Company generally records deferred revenue when it has the legal right to bill amounts owed. In the rare instance where a term has commenced but the fees have not yet been invoiced, the Company records an unbilled receivable. Deferred revenue that will be recognized during the succeeding 12-month period from the respective balance sheet date is recorded as deferred revenue, current, and the remaining portion is recorded as non-current. |
||||||||||||||||||||||||||||||||||||
| Accounts Receivable [Policy Text Block] | Accounts Receivable Accounts receivable primarily includes amounts billed to clients under their subscription agreements. The majority of the Company’s clients are well-established operating companies with investment-grade credit. For the periods ended December 31, 2012 and 2011, the Company has not incurred any losses on its accounts receivable. Based upon its historical collections experience and specific client information, the Company has determined that no allowance for doubtful accounts was required at either December 31, 2012 or 2011. |
||||||||||||||||||||||||||||||||||||
| Concentration of Risk [Policy Text Block] | Concentration of Risk The Company is subject to concentrations of credit risk principally attributable to cash, cash equivalents, investments, accounts receivable and other receivables. The Company’s cash balances (both, restricted and non-restricted) deposited in U.S. banks are non-interest bearing and are insured up to the Federal Deposit Insurance Corporation (“FDIC”) limits. Cash equivalents primarily consist of institutional money market funds, U.S. government and agency securities, municipal bonds and commercial paper denominated primarily in U.S. dollars. Investment policies have been implemented that limit purchases of debt securities to investment-grade securities. Credit risk with respect to accounts and other receivables is generally mitigated by short collection periods and/or subscription agreements that provide for payments in advance of the rendering of services. Three clients accounted for 22%, 18% and 13% of accounts receivable at December 31, 2012. Four clients accounted for 26%, 20%, 14% and 12% of accounts receivable at December 31, 2011. Two clients, neither of which was represented in the accounts receivable balance at December 31, 2012, accounted for 62% and 38% of other receivables at December 31, 2012. No client accounted for more than 10% of subscription fee revenue in any of the years ended December 31, 2012, 2011 or 2010. |
||||||||||||||||||||||||||||||||||||
| Fair Value Measurements [Policy Text Block] | Fair Value Measurements The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, which are required to be recorded at fair value, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as risks inherent in valuation techniques, transfer restrictions and credit risk. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 – Valuations based on quoted prices in active markets for identical assets or liabilities and readily accessible by the Company at the reporting date. Level 2 – Valuations based on inputs other than quoted prices included within Level 1 that are observable for assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 – Valuations based on inputs that are unobservable. The carrying amounts of the Company’s financial instruments, which include cash equivalents, investments, accounts receivable, other receivables and accounts payable, approximate their fair values due to their short maturities. Based on borrowing rates currently available to the Company for notes payable and other deferred payment obligations with similar terms, and considering the Company’s credit risk, the carrying value of deferred payment obligations approximates fair value. |
||||||||||||||||||||||||||||||||||||
| Cash and Cash Equivalents [Policy Text Block] | Cash and Cash Equivalents The Company’s cash and cash equivalents principally consist of institutional money market funds, corporate bonds, municipal bonds and commercial paper denominated primarily in U.S. dollars. Cash equivalents are highly liquid, short-term investments having an original maturity of 90 days or less that are readily convertible to known amounts of cash. |
||||||||||||||||||||||||||||||||||||
| Short-Term Investments [Policy Text Block] | Short-Term Investments The Company holds short-term investments in U.S. government and agency securities, commercial paper corporate bonds, and municipal bonds with maturities greater than 90 days. The Company considers its investments as available to support current operations. As a result, the Company classifies its investments including those with stated maturities beyond twelve months, as current assets in the accompanying consolidated balance sheets. The Company classifies these securities as “available-for-sale” and carries them at fair value on the consolidated balance sheets. Unrealized gains or losses are recorded, net of estimated taxes, in accumulated other comprehensive income (loss), a component of stockholders’ equity. Realized gains and losses are recognized upon sale. The specific identification method is used to determine the cost basis of fixed income securities sold. The Company periodically evaluates its investments for impairment due to declines in market value considered to be “other-than-temporary.” This evaluation consists of several qualitative and quantitative factors, including the Company’s ability and intent to hold the investment until a forecasted recovery occurs, as well as any decline in the investment quality of the security and the severity and duration of the unrealized loss. In the event of a determination that a decline in market value is other-than-temporary, the Company will recognize an impairment loss, and a new cost basis in the investment will be established. To date, the Company has not recorded any impairment related to its investments in its consolidated statements of operations. |
||||||||||||||||||||||||||||||||||||
| Property and Equipment [Policy Text Block] | Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using a straight-line method over the estimated useful lives of the related assets, which is generally three to five years. Maintenance and repairs are charged to expense as incurred, and improvements and betterments are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the consolidated balance sheet and any resulting gain or loss is reflected in the consolidated statement of operations in the period realized. Leasehold improvements are amortized on a straight-line basis over the term of the lease, or the useful life of the assets, whichever is shorter. |
||||||||||||||||||||||||||||||||||||
| Internal-Use Software and Website Development Costs [Policy Text Block] | Internal-Use Software and Website Development Costs The Company capitalizes development costs related to internal-use software and its website and records such amounts as property and equipment, net, on its consolidated balance sheets. These costs include personnel and personnel-related expenses and consultant fees incurred during the application development stages of the project. Costs related to preliminary project activities, minor enhancement and maintenance, and post implementation activities are expensed as incurred. Internal-use software is amortized on a straight-line basis over its useful life, which is generally three years, beginning on the date the software is placed into service. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. During the years ended December 31, 2012 and 2011, the Company capitalized $1.9 million and $1.2 million, respectively, of internal-use software and website development costs. Amortization of internal-use software was $0.8 million, $0.1 million and nil for the years ended December 31, 2012, 2011 and 2010, respectively. |
||||||||||||||||||||||||||||||||||||
| Patent Assets [Policy Text Block] | Patent Assets The Company generally acquires patent assets from third parties using cash and contractually deferred payments. Patent assets are recorded at fair value. The fair value of the assets acquired is generally based on the fair value of the consideration exchanged. The asset value includes the cost of legal and other fees associated with the acquisition of the assets. Costs incurred to maintain and prosecute patents and patent applications are expensed as incurred. Because each client generally receives a license to the vast majority of the Company’s patent assets, the Company is unable to reliably determine the pattern over which its patent assets are consumed. As a result, the Company amortizes each patent asset on a straight-line basis. The amortization period is equal to the asset’s estimated economic useful life. Estimating the economic useful life of patent assets requires significant management judgment. The Company considers various factors in estimating the economic useful lives of its patent assets, including the remaining statutory life of the underlying patents, the applicability of the assets to future clients, the vesting period for current clients to obtain perpetual licenses to such patent assets, any contractual commitments by clients that are related to such patent assets, its estimate of the period of time during which the Company may sign subscription agreements with prospective clients that may find relevance in the patent assets, the vesting period for which such clients earn the right to a perpetual license in the asset and the remaining contractual term of the Company’s existing clients at the time of acquisition. In certain instances, where the Company acquires patent assets and secures related client committed cash flows that extend beyond the statutory life of the underlying patents, the useful life may extend beyond the statutory life of the patents. As of December 31, 2012, the estimated economic useful life of the Company’s patent assets generally ranged from 24 to 60 months, and the weighted-average estimated economic useful life at the time of acquisition, excluding fully amortized patent assets, was 46 months. The Company periodically evaluates whether events and circumstances have occurred that may warrant a revision to the remaining estimated useful life of its patent assets. In instances where the Company sells patent assets, the amount of consideration received is compared to the asset’s carrying value to determine and recognize a gain or loss. |
||||||||||||||||||||||||||||||||||||
| Patent Asset Financing [Policy Text Block] | Patent Asset Financing The Company may use seller financing in the form of notes payable or contractually deferred payments for acquisitions of patent assets. In such cases, the acquired assets may serve as collateral or be otherwise encumbered during the term of the financing. Contractual amounts owed under such financing arrangements are recorded at fair value using a market rate of interest. If such financing arrangements do not have a stated interest rate, the Company imputes interest at a market rate (thereby discounting the future payments to present value) to account for the time-value-of-money component of the asset purchase. The difference between the contractual amounts due and the present value is recognized as interest expense over the period the payments are due. The Company records a corresponding patent asset for any such contractual obligations. Amounts due within approximately one year of the date of the acquisition under financing arrangements with no stated interest rate are recorded at face value. The interest component is imputed, if necessary, at the time of acquisition by using the then-current market yield of an index of comparable maturity securities with a credit rating comparable to that of the Company. |

| Impairment of Long-Lived Assets [Policy Text Block] | Impairment of Long-Lived Assets The Company assesses the recoverability of its long-lived assets, which includes patent assets, other intangible assets and property and equipment, when events or changes in circumstances indicate their carrying value may not be recoverable. Such events or changes in circumstances may include: a significant adverse change in the extent or manner in which a long-lived asset is being used, a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development of a long-lived asset, current or future operating or cash flow losses that demonstrate continuing losses associated with the use of a long-lived asset or a current expectation that, more-likely-than-not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The Company licenses the portfolio of patent assets to all of its clients and thus views these assets as a single asset group. The Company assesses recoverability of a long-lived asset by determining whether the carrying value of these assets can be recovered through projected undiscounted cash flows. If the carrying value of the assets exceeds the forecasted undiscounted cash flows, an impairment loss is recognized, and is recorded as the amount by which the carrying value exceeds the estimated fair value. An impairment loss is charged to operations in the period in which management determines such impairment. To date, there have been no impairments of long-lived assets identified. |
||||||||||||||||||||||||||||||||||||
| Assets Held for Sale [Table Text Block] | Assets Held for Sale The Company classifies assets as held for sale when certain criteria are met, including: management’s commitment to a plan to sell the assets; the availability of the assets for immediate sale in their present condition; whether an active program to locate buyers and other actions to sell the assets has been initiated; whether the sale of the assets is probable and their transfer is expected to qualify for recognition as a completed sale within one year; whether the assets are being marketed at reasonable prices in relation to their fair value; and how likely it is that significant changes will be made to the plan to sell the assets. There were no assets held for sale at December 31, 2012 or 2011. |
||||||||||||||||||||||||||||||||||||
| Goodwill [Policy Text Block] | Goodwill Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company evaluates goodwill for impairment on an annual basis during its third fiscal quarter or whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. In accordance with ASC Topic 350, Intangibles - Goodwill & Other (“ASC Topic 350”), the goodwill impairment test consists of a two-step process, if necessary. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC Topic 350. The more likely than not threshold is defined as having a likelihood of more than 50 percent. If, after assessing the totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary and goodwill is considered to be unimpaired. However, if based on the Company’s qualitative assessment, it concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company will proceed with performing the two-step process. The first step of the impairment test involves comparing the fair value of the reporting unit to its net book value, including goodwill. As of December 31, 2012, the Company had one reporting unit. If the net book value exceeds its fair value, then the Company would perform the second step of the goodwill impairment test to determine the amount of the impairment loss. The impairment loss would be calculated by comparing the implied fair value of the Company to its net book value. In calculating the implied fair value of the Company’s goodwill, the fair value of the Company would be allocated to all of the other assets and liabilities based on their fair values. The excess of the fair value of the Company over the amount assigned to its other assets and liabilities is the implied fair value of goodwill. An impairment loss would be recognized when the carrying amount of goodwill exceeds its implied fair value. There have been no impairments of goodwill recorded in the Company’s consolidated statements of operations through December 31, 2012. |

| Intangible Assets, Net [Policy Text Block] | Intangible Assets, Net Intangible assets, net primarily consists of intangible assets acquired from other companies as a result of acquisitions. Such assets are capitalized and amortized on a straight-line basis over their estimated useful lives. Intangible assets, net excludes patent related intangible assets, which are recorded within patent assets, net in the accompanying consolidated balance sheets. |
||||||||||||||||||||||||||||||||||||
| Advertising Costs [Policy Text Block] | Advertising Costs The Company expenses advertising costs as they are incurred. Advertising expenses were not material for any of the periods presented. |
||||||||||||||||||||||||||||||||||||
| Foreign Currency Accounting [Policy Text Block] | Foreign Currency Accounting The Company’s subscription agreements are denominated in U.S. dollars; however, several of the Company’s clients report revenue and operating income in foreign currencies. As subscription fees are determined using the reported revenue and operating income of the Company’s clients, a significant sustained change in exchange rates could result in a change in subscription fees from clients reporting revenue and operating income in a currency other than the U.S. dollar. The Company’s expenses are incurred primarily in the United States, with a small portion of expenses incurred and denominated in Japanese Yen and the Euro. The functional currency of the Company’s international subsidiaries is the U.S. dollar. Monetary assets and liabilities are remeasured using the current exchange rate at the balance sheet date. Non-monetary assets and liabilities and capital accounts are remeasured using historical exchange rates. Expenses are remeasured using the average exchange rates in effect during the period. Foreign currency exchange gains and losses, which have not been material for any periods presented, are included in the consolidated statements of operations under other income (expense), net. |
||||||||||||||||||||||||||||||||||||
| Income Taxes [Policy Text Block] | Income Taxes The Company accounts for income taxes using an asset and liability approach, which requires the recognition of deferred tax assets or liabilities for the tax-effected temporary differences between the financial reporting and tax bases of its assets and liabilities and for net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefits that, based on available evidence, are not expected to be realized. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income, and to the extent the Company believes that recovery is not likely, the Company establishes a valuation allowance. Judgment is required in determining the Company’s provision for income taxes, deferred tax assets, and liabilities and any valuation allowance recorded against the net deferred tax assets. The Company had not applied a valuation allowance against its deferred tax balances for the years ended December 31, 2012 or 2011. The calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across its global operations. ASC 740 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. ASC 740 also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company recognizes tax liabilities in accordance with ASC 740 and adjusts these liabilities when its judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from its current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information is available. |
||||||||||||||||||||||||||||||||||||
| Stocl-Based Compensation [Policy Text Block] | Stock-Based Compensation The Company accounts for stock-based compensation under ASC 718, Compensation-Stock Compensation (“ASC 718”). ASC 718 requires that compensation expense for all equity-settled awards made to employees and directors be measured and recognized based on estimated grant date fair values. These equity awards include stock options and restricted stock units (“RSUs”). Stock-based compensation expense for RSUs granted to employees and directors is measured based on the fair market value of the Company’s common stock on the date of grant. Stock-based compensation expense for stock options awarded to employees and directors is estimated based on the fair value of each stock option using an option pricing model. The value of awards expected to vest is recognized as expense on a straight-line basis over the requisite service period. The Company accounts for stock-based compensation for equity-settled awards issued to non-employees in exchange for goods and services under ASC 505-50, Equity-Based Payments to Non-Employees (“ASC 505-50”). ASC 505-50 requires that equity awards issued to non-employees be measured at the fair value as of the date at which either the commitment for performance by the non-employee to earn the award is reached or the date the non-employee’s performance is complete. Until that point is reached, the award must be revalued at each reporting period with the true-up to expense recorded in the then current period earnings. The value of the award is recognized as an expense over the requisite service period. The Company selected the Black-Scholes option pricing model as the most appropriate method for determining the estimated fair value for stock options. The Black-Scholes model requires the use of highly subjective and complex assumptions which determine the fair value of stock-based awards, including the option’s expected term and the price volatility of the underlying stock. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. See Note 15. |
||||||||||||||||||||||||||||||||||||
| Business Combinations [Policy Text Block] | Business Combinations The Company applies the provisions of ASC 805, Business Combinations (“ASC 805”), in the accounting for its business acquisitions. ASC 805 requires companies to recognize goodwill separately from the assets acquired and liabilities assumed, which are valued at their acquisition date fair values. Goodwill as of the acquisition date represents the excess of the purchase price over the fair values of the assets acquired and the liabilities assumed. The Company uses significant estimates and assumptions, including fair value estimates, to determine fair value of assets acquired and liabilities assumed and when applicable the related useful lives of the acquired assets, as of the business combination date. When those estimates are provisional, the Company refines them as necessary during the measurement period. The measurement period is the period after the acquisition date, not to exceed one year, in which the Company may gather new information about facts and circumstances that existed as of the acquisition date to adjust the provisional amounts recognized. Measurement period adjustments are applied retrospectively, if material. All other adjustments are recorded to the consolidated statements of operations. |

| Recently Issued Accounting Standards [Text Block] | Recently Issued Accounting Standards In February 2013, the FASB issued Accounting Standards Update (“ASU”) 2013-02, Reporting of Amounts of Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”), which amends Comprehensive Income (Topic 220) in the ASC. These amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amendments in ASU 2013-02 will be effective for fiscal periods beginning after December 15, 2012. The adoption of ASU 2013-02 is not expected to have a material impact on the Company’s financial position or results of operations. In October 2012, the FASB issued ASU 2012-04, Technical Corrections and Improvements (“ASU 2012-04”), which amends a wide range of topics in the ASC. These amendments include technical corrections and improvements to the ASC and conforming amendments related to fair value measurements. The amendments in ASU 2012-04 will be effective for fiscal periods beginning after December 15, 2012. The adoption of ASU 2012-04 is not expected to have a material impact on the Company’s financial position or results of operations. In July 2012, the FASB issued ASU 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment (“ASU 2012-02”), which amends ASU 2011-08, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment and permits an entity to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with Subtopic 350-30, Intangibles - Goodwill and Other - General Intangibles Other than Goodwill. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted, including for annual and interim impairment tests performed as of a date before July 27, 2012, if a public entity’s financial statements for the most recent annual or interim period have not yet been issued or, for nonpublic entities, have not yet been made available for issuance. The adoption of ASU 2012-02 is not expected to have a material impact on the Company’s financial position or results of operations. |
||||||||||||||||||||||||||||||||||||
| Recently Adopted Accounting Standards [Policy Text Block] | Recently Adopted Accounting Standards In August 2012, the FASB issued ASU 2012-03, Technical Amendments and Corrections to SEC Sections: Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 114 (“SAB 114”), Technical Amendments Pursuant to SEC Release No. 33-9250, and Corrections Related to FASB Accounting Standards Update 2010-22, which amends various SEC paragraphs pursuant to the issuance of SAB114. This ASU became effective upon issuance, and the adoption of this ASU had no impact on the Company’s financial position or results of operations. In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income (“ASU 2011-05”), which requires companies to present the components of net income and other comprehensive income either in a single continuous statement or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. ASU 2011-05 does not change the items which must be reported in other comprehensive income, how such items are measured or when they must be reclassified to net income. Additionally, ASU 2011-05 does not affect the calculation or reporting of earnings per share. On January 1, 2012, the Company adopted this ASU and elected the two-statement presentation option. Other than the change in presentation, the adoption of this ASU had no impact on the Company’s financial position or results of operations. |

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef

The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.
