| 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, patent rights 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, in August 2012, the Company began underwriting patent infringement liability insurance policies to insure against certain costs of litigation from non-practicing entities (“NPEs”). As of and for the year ended December 31, 2013, the effect of the insurance policies that have been issued was not material to the Company’s results of operations or financial condition. |

| 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. 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 the contingency has been satisfied. 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 typically 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 syndicated acquisitions. The accounting for syndicated acquisitions can be 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 syndicated 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. Revenue recognition for arrangements with multiple deliverables. A multiple-element arrangement includes the sale of a subscription to the Company’s patent risk management solution and an insurance policy to cover certain costs associated with patent infringement lawsuits by NPEs, each of which are individually considered separate units of accounting. Each element within a multiple-element arrangement is accounted for as a separate unit of accounting given that the delivered products have value to the customer on a standalone basis. The Company considers a deliverable to have standalone value if the product or service is sold separately by itself or another vendor. Although there’s a requirement to purchase both products concurrently, the delivery of insurance coverage is not dependent on a client’s subscription to the Company’s patent risk management solution. The Company’s insurance product offering is unique, however a company would be able to purchase insurance coverage as a standalone product from other providers. The Company sells its patent risk management solution on a standalone basis as its core business product. The Company has determined its best estimate of selling price (“BESP”) for a subscription to our patent risk management solution based on the following:
The Company has determined its BESP for its insurance product based on the following:
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 anniversary 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 and the applicable service period has commenced. 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 years ended December 31, 2013 and 2012, 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, 2013 or 2012. 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 non-restricted cash balances 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. Four clients individually accounted for 18%, 16%, 13% and 11% of accounts receivable at December 31, 2013. Three clients individually accounted for 22%, 18% and 13% of accounts receivable at December 31, 2012. Two clients, neither of which was represented in the accounts receivable balance at December 31, 2012, individually 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, 2013, 2012 or 2011. 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 commercial paper, institutional money market funds, U.S. government and agency securities and municipal bonds 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. Restricted Cash Restricted cash consists of a certificate of deposit established as collateral for the Company’s office lease agreement. At December 31, 2013 and 2012, the Company had restricted cash (current and non-current) of $1.8 million and nil, respectively. Short-Term Investments The Company holds short-term investments in municipal and corporate bonds maturing between 90 days and 12 months, commercial paper and U.S. government and agency securities. 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, Net 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, 2013, 2012 and 2011, the Company capitalized $1.2 million, $1.9 million and $1.2 million, respectively, of internal-use software and website development costs. Amortization of internal-use software was $1.1 million, $0.8 million and $0.1 million for the years ended December 31, 2013, 2012 and 2011, respectively. Patent Assets, Net The Company generally acquires patent assets from third parties using cash and contractually deferred payments. Patent assets are recorded at fair value at acquisition. 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 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, 2013, the estimated economic useful life of the Company’s patent assets generally ranged from 24 to 60 months. The weighted-average estimated economic useful life of patent assets acquired since inception was 47 months. The weighted-average estimated economic useful life of patent assets acquired during the year ended December 31, 2013 was 39 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. 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. Goodwill The Company reviews goodwill for impairment at least annually on September 30 or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. For fiscal year 2013, the Company elected to first assess the qualitative factors to determine whether it is more likely than not that the fair value of its single reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment under ASC Topic 350, Intangibles - Goodwill & Other (“ASC Topic 350”). This qualitative assessment evaluated factors including, but not limited to, economic market and industry conditions, cost factors and the overall financial performance of the Company. No impairment charges were recorded as a result of the Company’s 2013 annual impairment analysis. If the Company were to determine that it is more likely than not that the fair value of its single reporting unit is less than its carrying amount, then the two-step goodwill impairment test is performed. The first step in identifying a potential impairment compares the fair value of the reporting unit with its carrying amount. If the carrying amount exceeds its fair value, the second step would need to be performed; otherwise, no further step is required. The second step, measuring the impairment loss, compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. Any excess of the goodwill carrying amount over the implied fair value is recognized as an impairment charge, and the carrying value of goodwill is written down to fair value. 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 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 reflected 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 within 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 did not apply a valuation allowance against its deferred tax balances at December 31, 2013 or 2012. 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, Income Taxes (“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. The tax expense or benefit for extraordinary items, unusual or infrequently occurring items and items that do not represent a tax effect of current-year ordinary income are treated as discrete items and recorded in the interim period in which the events occur. Stock-Based Compensation The Company accounts for stock-based compensation for equity-settled awards issued to employees and directors under ASC 718, Compensation-Stock Compensation (“ASC 718”). ASC 718 requires that stock-based compensation expense for equity-settled awards made to employees and directors be measured based on the estimated grant date fair value and recognized over the requisite service period. These equity-settled awards include stock options, restricted stock units (“RSUs”) and performance-based RSUs with a market condition (“PBRSUs”). The fair value of stock options is estimated as of the date of grant using the Black-Scholes option-pricing model. The fair value of RSUs is estimated based on the fair market value of the Company’s common stock on the date of grant. For stock options and RSUs, the fair value of award that is expected to vest is recognized as compensation expense on a straight-line basis over the requisite service period. Because stock-based compensation expense is based on awards ultimately expected to vest, it reflects estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. Previously recognized expense is reversed for the portion of awards forfeited prior to vesting. The fair value of PBRSUs is estimated as of the date of grant using the Monte-Carlo simulation model. For PBRSUs, stock-based compensation expense is recognized over the derived service period for each tranche (or market condition). Because the Company’s PBRSUs have multiple derived service periods, it uses the graded-vesting attribution method. The graded vesting attribution method requires a company to recognize compensation expense over the requisite service period for each vesting tranche of the award as though the award were, in substance, multiple awards. The compensation expense for these awards will only be reversible if the employee terminates prior to completing the requisite service periods for these award (i.e., compensation expense will not be reversed if the market condition is not met). Estimating the fair value of equity-settled awards as of the grant date using valuation models, such as the Black-Scholes option-pricing model and Monte-Carlo simulation model, is affected by assumptions regarding a number of complex variables. 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 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 equity-settled award. 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-settled 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. 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, 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. Reserves for Known and Incurred but not Reported Claims Reserves for known and incurred but not reported claims represent estimated claims costs and related expenses for patent infringement liability insurance policies in effect. Reserves for known claims are established based on individual case estimates. The Company uses actuarial models and techniques to estimate the reserve for incurred but not reported claims. Loss expense for known and incurred but not reported claims are charged to earnings after deducting recoverable amounts under the Company’s reinsurance contract. Recently Adopted Accounting Standards In February 2013, the FASB issued 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 are effective for the Company’s interim and annual fiscal periods which began January 1, 2013. The adoption of ASU 2013-02 did not have a material impact on the Company’s consolidated financial statements. 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 are effective for the Company’s interim and annual fiscal periods which began January 1, 2013. The adoption of ASU 2012-04 did not have a material impact on the Company’s consolidated financial statements. 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 in ASU 2012-02 are effective for the Company’s interim and annual fiscal periods which began January 1, 2013. The adoption of ASU 2012-02 did not have a material impact on the Company’s consolidated financial statements. |

| 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 redeemable convertible preferred stock non-cumulative dividends, among common stockholders, restricted stockholders and 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 (in thousands, except for per share data):
For the years ended December 31, 2013, 2012 and 2011 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, 2013, the estimated economic useful lives of the Company’s patent assets generally ranged from 24 to 60 months. As of December 31, 2013, the weighted-average estimated economic useful life at the time of acquisition was 47 months. The following table summarizes the expected future annual amortization expense of patent assets as of December 31, 2013 (in thousands):
Amortization expense was $105.5 million, $80.4 million and $62.3 million for the years ended December 31, 2013, 2012 and 2011, respectively. Syndicated Acquisitions Syndicated 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. |

| Commitments And Contingencies [Text Block] | Commitments and Contingencies Operating Lease Commitments The Company leases its facilities under non-cancelable lease agreements. In March 2012, the Company entered into an amended lease agreement related to its San Francisco, California office space. The amendment, which took effect on May 1, 2013, increased the rentable space to approximately 67,000 total square feet and extended the term through October 2019. The monthly base rent payments pursuant to this lease are approximately $0.3 million per month, increasing to approximately $0.4 million per month over the life of the lease. In October 2013, the Company entered into an agreement to sublease a portion of its San Francisco, California office space. This sublease will take effect on February 1, 2014 and will continue for a 36-month term through January 2017. Rent expense related to non-cancelable operating leases was $3.5 million, $2.4 million and $1.7 million for the years ended December 31, 2013, 2012 and 2011, respectively. As of December 31, 2013, the future minimum lease payments required under non-cancelable operating leases and the future minimum payments to be received from non-cancelable subleases were 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, 2013 or 2012. In June 2013, Kevin O’Halloran, as Trustee of the Liquidating Trust of Teltronics, Inc. (the “Debtor”), filed a complaint in the U.S. Bankruptcy Court for the Middle District of Florida against the Company and Harris Corporation (the “Defendants”). The complaint alleges that the Defendants are liable under federal and state bankruptcy law regarding fraudulent transfers for the value of a patent portfolio purchased by the Company from Harris Corporation pursuant to an agreement entered into in January 2009, and within four years of the date the Debtor filed its petition in bankruptcy. 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. In February 2013, Volkswagen Group of America, Inc. (“Volkswagen”) filed a third-party 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 into with Norman and Saxon Innovations, LLC (“Saxon”) in January 2010. The claims allege that the Company, together with Norman and Saxon, violated federal antitrust law and Texas antitrust law. Volkswagen seeks declaratory relief, unspecified monetary damages, and injunctive relief. 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 complaint 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 complaint alleges that the Defendants violated federal antitrust law, California antitrust law and California unfair competition law. The complaint further alleges 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, 2013 or 2012. 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. Reserves for Known and Incurred but not Reported Claims In August 2012, the Company began offering insurance to cover certain costs of litigation brought against its insured clients by NPEs. As of December 31, 2013, the Company had a total of 25 active policies and has recorded a reserve of $0.6 million, net of amounts recoverable from reinsurers, for known and incurred but not reported claims that represent estimated claim costs and related expenses. The Company regularly reviews loss reserves using a variety of actuarial techniques and updates them as its loss experience develops. Patent Asset Purchase Commitments In November 2013, the Company entered into an agreement to acquire patent assets for an aggregate purchase price of $3.0 million. Pursuant to this agreement, the Company paid the purchase price and acquired the patent assets in January 2014. |

| Stock-Based Compensation [Text Block] | Stockholder’ Equity Common Stock As of December 31, 2013, under the Company’s amended and restated certificate of incorporation, the Company is authorized to issue 200 million shares of common stock with a par value of $0.0001 per share. Preferred Stock As of December 31, 2013, 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 initially reserved 1,500,000 shares of common stock for future issuance under the 2011 Plan. In March 2013 and 2012, the Company reserved an additional 1,000,000 and 2,457,269 shares of common stock, respectfully, for future issuance under the 2011 Plan. As of December 31, 2013, there were 2,450,958 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. RSUs 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. RSUs granted to existing employees generally vest ratably each quarter over the 16 quarters following the date of grant. PBRSUs granted to employees may vest 25% on each anniversary of the grant date, provided that the average closing price per share of the Company’s common stock for any 90-calendar day period during the year preceding such anniversary date is equal to or greater than 1.25 times the Company’s stock price on the grant date or on the anniversary of the grant date. To the extent that a portion of the award does not vest on a specific anniversary date, it will remain eligible to vest in any of following three successive anniversaries of the grant date, provided that the market conditions have been satisfied at that time. A summary of the Company’s activity under its equity-settled award plans and related information is as follows (in thousands, except per share data):
The aggregate intrinsic value of stock options exercised during the years ended December 31, 2013, 2012 and 2011 was $13.5 million, $23.8 million and $19.0 million, respectively. The total fair value of stock options vested during the years ended December 31, 2013, 2012 and 2011 was $9.1 million, $8.5 million and $4.8 million, respectively. Restricted Stock Units The summary of restricted stock unit activity, which includes PBRSUs, is as follows (in thousands, except for per share data):
The total fair value of RSUs vested during the years ended December 31, 2013, 2012 and 2011 was $6.6 million, $1.6 million and $0.2 million, respectively. In October 2013, the Board of Directors approved net-share settlement for tax withholdings on RSU vesting. In 2013, the Company withheld issuing 45,338 shares of its common stock based on the value of the RSUs on their vesting dates as determined by the Company’s closing common stock price. Total payments for the employees’ minimum tax obligations to taxing authorities were $0.8 million for the year ended December 31, 2013, and were recorded as a reduction to additional paid-in capital and reflected as a financing activity within the consolidated statements of cash flows. The net-share settlements reduced the number of shares that would have otherwise been issued on the vesting date and increased the number of shares reserved for future issuance under the 2011 Plan. Stock-Based Compensation Related to Employees and Directors The Company estimates the fair value of stock options using the Black-Scholes option pricing model. 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 RSUs granted to employees and non-employee directors is measured by reference to the fair value of the underlying shares on the date of grant. PBRSUs contain both service and market conditions that affect the quantity of awards that will vest. During the year ended December 31, 2013, the Company granted 175,000 PBRSUs. The Company estimates the grant date fair value of the PBRSUs using the Monte Carlo simulation model. The weighted-average assumptions used to estimate the fair value of PBRSUs and the resulting fair values are as follows:
Stock-based compensation expense related to stock options granted to employees and non-employee directors was $8.5 million, $7.9 million and $5.5 million for the years ended December 31, 2013, 2012 and 2011, respectively. Stock-based compensation expense related to RSUs granted to employees and non-employee directors was $6.9 million, $2.0 million and $0.4 million for the years ended December 31, 2013, 2012 and 2011, respectively. Stock-based compensation expense related to PBRSUs granted to employees was $0.4 million for the year ended December 31, 2013 and nil for both the years ended December 31, 2012 and 2011. As of December 31, 2013, there was $10.5 million and $22.8 million of unrecognized compensation cost related to stock options and RSUs, including PBRSUs, respectively, which is expected to be recognized over a weighted-average period of 2.1 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. No awards were granted to non-employees in exchange for goods and services during the years ended December 31, 2013 and 2012. During the year ended December 31, 2011, the Company issued 10,000 shares of common stock, 62,632 RSUs, and 75,000 stock options to non-employees in exchange for services. 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 $0.2 million, $0.3 million and $0.9 million for the years ended December 31, 2013, 2012 and 2011, respectively. Non-employee stock-based compensation expense related to RSUs was $0.2 million, $0.3 million and $0.2 million for the years ended December 31, 2013, 2012 and 2011, 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 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, 2013, 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, 2013, the Company had state net operating loss carryforwards of $2.0 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 indefinitely 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 Company believes that the the potential liability would be immaterial. Uncertain Tax Positions As of December 31, 2013, the Company’s total amount of unrecognized tax benefits was $2.0 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, 2013 and 2012, the Company recognized $17,000 and $0.1 million respectively, of interest and penalties associated with unrecognized tax benefits. The Company’s 2010 tax year is currently under examination by the State of California Franchise Tax Board. The Company does not expect a material impact on its consolidated financial statements as a result of this examination.

| 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. |
||||||||||||||||||||||||||||||||||||||||||||
| 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 the contingency has been satisfied. 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 typically 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 syndicated acquisitions. The accounting for syndicated acquisitions can be 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 syndicated 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. Revenue recognition for arrangements with multiple deliverables. A multiple-element arrangement includes the sale of a subscription to the Company’s patent risk management solution and an insurance policy to cover certain costs associated with patent infringement lawsuits by NPEs, each of which are individually considered separate units of accounting. Each element within a multiple-element arrangement is accounted for as a separate unit of accounting given that the delivered products have value to the customer on a standalone basis. The Company considers a deliverable to have standalone value if the product or service is sold separately by itself or another vendor. Although there’s a requirement to purchase both products concurrently, the delivery of insurance coverage is not dependent on a client’s subscription to the Company’s patent risk management solution. The Company’s insurance product offering is unique, however a company would be able to purchase insurance coverage as a standalone product from other providers. The Company sells its patent risk management solution on a standalone basis as its core business product. The Company has determined its best estimate of selling price (“BESP”) for a subscription to our patent risk management solution based on the following:
The Company has determined its BESP for its insurance product based on the following:
|
||||||||||||||||||||||||||||||||||||||||||||
| 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 anniversary 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 and the applicable service period has commenced. 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 years ended December 31, 2013 and 2012, 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, 2013 or 2012. |
||||||||||||||||||||||||||||||||||||||||||||
| 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 non-restricted cash balances 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. Four clients individually accounted for 18%, 16%, 13% and 11% of accounts receivable at December 31, 2013. Three clients individually accounted for 22%, 18% and 13% of accounts receivable at December 31, 2012. Two clients, neither of which was represented in the accounts receivable balance at December 31, 2012, individually 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, 2013, 2012 or 2011. |
||||||||||||||||||||||||||||||||||||||||||||
| 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 commercial paper, institutional money market funds, U.S. government and agency securities and municipal bonds 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 municipal and corporate bonds maturing between 90 days and 12 months, commercial paper and U.S. government and agency securities. 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, Net 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, 2013, 2012 and 2011, the Company capitalized $1.2 million, $1.9 million and $1.2 million, respectively, of internal-use software and website development costs. Amortization of internal-use software was $1.1 million, $0.8 million and $0.1 million for the years ended December 31, 2013, 2012 and 2011, respectively. |
||||||||||||||||||||||||||||||||||||||||||||
| Patent Assets, Net [Policy Text Block] | Patent Assets, Net The Company generally acquires patent assets from third parties using cash and contractually deferred payments. Patent assets are recorded at fair value at acquisition. 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 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, 2013, the estimated economic useful life of the Company’s patent assets generally ranged from 24 to 60 months. The weighted-average estimated economic useful life of patent assets acquired since inception was 47 months. The weighted-average estimated economic useful life of patent assets acquired during the year ended December 31, 2013 was 39 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. |
||||||||||||||||||||||||||||||||||||||||||||
| 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. |
||||||||||||||||||||||||||||||||||||||||||||
| Goodwill [Policy Text Block] | Goodwill The Company reviews goodwill for impairment at least annually on September 30 or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. For fiscal year 2013, the Company elected to first assess the qualitative factors to determine whether it is more likely than not that the fair value of its single reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment under ASC Topic 350, Intangibles - Goodwill & Other (“ASC Topic 350”). This qualitative assessment evaluated factors including, but not limited to, economic market and industry conditions, cost factors and the overall financial performance of the Company. No impairment charges were recorded as a result of the Company’s 2013 annual impairment analysis. If the Company were to determine that it is more likely than not that the fair value of its single reporting unit is less than its carrying amount, then the two-step goodwill impairment test is performed. The first step in identifying a potential impairment compares the fair value of the reporting unit with its carrying amount. If the carrying amount exceeds its fair value, the second step would need to be performed; otherwise, no further step is required. The second step, measuring the impairment loss, compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. Any excess of the goodwill carrying amount over the implied fair value is recognized as an impairment charge, and the carrying value of goodwill is written down to fair value. |
||||||||||||||||||||||||||||||||||||||||||||
| 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 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 reflected 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 within 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 did not apply a valuation allowance against its deferred tax balances at December 31, 2013 or 2012. 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, Income Taxes (“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. The tax expense or benefit for extraordinary items, unusual or infrequently occurring items and items that do not represent a tax effect of current-year ordinary income are treated as discrete items and recorded in the interim period in which the events occur. |

| Stock-Based Compensation [Policy Text Block] | Stock-Based Compensation The Company accounts for stock-based compensation for equity-settled awards issued to employees and directors under ASC 718, Compensation-Stock Compensation (“ASC 718”). ASC 718 requires that stock-based compensation expense for equity-settled awards made to employees and directors be measured based on the estimated grant date fair value and recognized over the requisite service period. These equity-settled awards include stock options, restricted stock units (“RSUs”) and performance-based RSUs with a market condition (“PBRSUs”). The fair value of stock options is estimated as of the date of grant using the Black-Scholes option-pricing model. The fair value of RSUs is estimated based on the fair market value of the Company’s common stock on the date of grant. For stock options and RSUs, the fair value of award that is expected to vest is recognized as compensation expense on a straight-line basis over the requisite service period. Because stock-based compensation expense is based on awards ultimately expected to vest, it reflects estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. Previously recognized expense is reversed for the portion of awards forfeited prior to vesting. The fair value of PBRSUs is estimated as of the date of grant using the Monte-Carlo simulation model. For PBRSUs, stock-based compensation expense is recognized over the derived service period for each tranche (or market condition). Because the Company’s PBRSUs have multiple derived service periods, it uses the graded-vesting attribution method. The graded vesting attribution method requires a company to recognize compensation expense over the requisite service period for each vesting tranche of the award as though the award were, in substance, multiple awards. The compensation expense for these awards will only be reversible if the employee terminates prior to completing the requisite service periods for these award (i.e., compensation expense will not be reversed if the market condition is not met). Estimating the fair value of equity-settled awards as of the grant date using valuation models, such as the Black-Scholes option-pricing model and Monte-Carlo simulation model, is affected by assumptions regarding a number of complex variables. 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 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 equity-settled award. 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-settled 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. |
||||||||||||||||||||||||||||||||||||||||||||
| 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, 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. |

| Reserves for Known and Incurred but not Reported Claims [Policy Text Block] | Reserves for Known and Incurred but not Reported Claims Reserves for known and incurred but not reported claims represent estimated claims costs and related expenses for patent infringement liability insurance policies in effect. Reserves for known claims are established based on individual case estimates. The Company uses actuarial models and techniques to estimate the reserve for incurred but not reported claims. Loss expense for known and incurred but not reported claims are charged to earnings after deducting recoverable amounts under the Company’s reinsurance contract. |

| Recently Adopted Accounting Standards [Policy Text Block] | Recently Adopted Accounting Standards In February 2013, the FASB issued 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 are effective for the Company’s interim and annual fiscal periods which began January 1, 2013. The adoption of ASU 2013-02 did not have a material impact on the Company’s consolidated financial statements. 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 are effective for the Company’s interim and annual fiscal periods which began January 1, 2013. The adoption of ASU 2012-04 did not have a material impact on the Company’s consolidated financial statements. 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 in ASU 2012-02 are effective for the Company’s interim and annual fiscal periods which began January 1, 2013. The adoption of ASU 2012-02 did not have a material impact on the Company’s consolidated financial statements. |

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
