| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Nature Of Business | Nature of Business RPX Corporation (also referred to herein as “RPX” or the “Company”) helps companies reduce patent litigation risk and corporate legal expense through two primary service offerings: its patent risk management services and its discovery services. The Company's patent risk management services help companies reduce patent-related risk and expense through subscription-based services that facilitate more efficient exchanges of value between owners and users of patents compared to transactions driven by actual or threatened litigation. The Company’s patent risk management membership clients pay an annual subscription fee and in return, receive access to substantially all of the Company's patent portfolio as well as an array of services provided throughout their membership. Access to these services is available primarily through discussions with the Company's professionals—particularly client relations and its team of patent experts, as well as through a proprietary database, and attendance at periodic conferences. In addition to its subscription-based patent risk management services, the Company underwrites patent infringement liability insurance policies to insure against certain costs of litigation. The Company uses a reinsurance subsidiary company to assume a portion of the underwriting risk on the insurance policies that the Company issues on behalf of a Lloyd's of London underwriting syndicate. To date, the effect of the insurance policies that the Company has assumed through its reinsurance business has not been material to the Company’s results of operations, financial condition, or cash flows. In January 2016, the Company acquired Inventus Solutions, Inc. ("Inventus"), now a wholly owned subsidiary of the Company, and began offering its discovery services, which consist of technology-enabled services to assist law firms and corporate legal departments manage costs and risks related to the litigation discovery process. The Company's discovery services include data hosting and backup, data processing and collection, project management, document review, and traditional document production. All of these services are designed to streamline the administration of litigation, investigations, and regulatory compliance. |

Basis of Presentation and Significant Accounting Policies |

| Accounting Policies [Abstract] | |
| Basis Of Presentation And Significant Accounting Policies | Basis of Presentation and Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated balance sheet as of September 30, 2017, the condensed consolidated statements of operations and the condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2017 and 2016, and the condensed consolidated statements of cash flows for the nine months ended September 30, 2017 and 2016, are unaudited. The condensed consolidated balance sheet as of December 31, 2016 was derived from the audited consolidated financial statements which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016, which was filed with the U.S. Securities and Exchange Commission (“SEC”) on February 28, 2017. The unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America and with the instructions for Form 10-Q and Regulation S-X for interim financial statements. Accordingly, they do not include all of the information and notes required for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring items, necessary to state fairly the results of the interim periods have been included in the accompanying financial statements. Operating results for the three or nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for any subsequent interim period or for the year ending December 31, 2017. Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the nine months ended September 30, 2017, as compared to the significant accounting policies presented under the heading “Basis of Presentation and Significant Accounting Policies” in Note 2 of the Notes to Consolidated Financial Statements in Part II, Item 8 of the Company’s Annual Report on Form 10-K filed with the SEC on February 28, 2017. In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Compensation – Stock Compensation (Topic 718) ("ASU 2016-09"). ASU 2016-09 identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The amendments in this update became effective in the first quarter of 2017. The Company adopted this standard on January 1, 2017 and the standard did not have a material impact on its consolidated financial statements. Recent Accounting Pronouncements In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09") which clarifies the changes to terms or conditions of a share-based payment award that require an entity to apply modification accounting. ASU 2017-09 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. Early application is permitted and prospective application is required. The Company is currently evaluating impact of this guidance on its consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities (“ASU 2017-08”), which shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public entities, ASU 2017-08 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements. In February 2017, the FASB issued ASU No. 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets: Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets. This ASU was issued to clarify the scope of the previous standard and to add guidance for partial sales of nonfinancial assets and is effective for fiscal years and interim periods within those years beginning after December 15, 2017. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment, which simplifies the subsequent measurement of goodwill and eliminates the two-step goodwill impairment test. Under the new guidance, an annual or interim goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The amendment also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and two-step goodwill impairment test. The ASU is effective prospectively for fiscal years and interim periods within those years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company will early adopt this ASU for goodwill impairment tests beginning in 2017. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations: Clarifying the Definition of a Business, which provides a more robust framework to use in determining when a set of assets and activities is a business. This ASU is effective prospectively for fiscal years and interim periods within those years beginning after December 15, 2017. The Company will apply this guidance to applicable transactions after the adoption date. The FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as well as associated ASUs 2016-08, 2016-10, 2016-12, 2016-20, 2017-13 (the foregoing ASUs collectively, "Topic 606"), which will supersede most existing revenue recognition guidance in U.S. GAAP. Topic 606 becomes effective for annual and interim periods beginning after December 15, 2017; early adoption is permitted for annual and interim periods beginning after December 15, 2016. The Company plans to adopt Topic 606 on January 1, 2018, using the full retrospective method of adoption. This standard will have a material effect on the Company's consolidated financial statements due to the identification of multiple performance obligations from its patent risk management membership subscription and the timing of recognition for these separable performance obligations. Specifically, the Company will recognize separate performance obligations under Topic 606 for certain discrete patent assets transferred to its membership clients as well as for access to the Company's patent portfolio clients obtain when becoming a member or renewing membership. The revenue generated from these additional performance obligations will be recognized at a point in time. Under existing U.S. GAAP, the Company generally recognizes the membership fees ratably on a gross basis over the term of the customer contract. Therefore, the adoption of Topic 606 may increase the variability of the revenue recognized from the Company's patent risk management services from period to period. The Company will determine whether revenue should be recognized on a gross or net basis under Topic 606, which may result in revenue which is recognized on a gross basis under current U.S. GAAP to be recognized on a net basis under Topic 606 due to the additional separable performance obligations. Additionally, based on the Company's initial assessment, it does not expect Topic 606 to have a material impact on its discovery services segment. |

| Net Income Per Share | Net Income Per Share Basic and diluted net income per share are computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by using the weighted-average number of shares of common stock outstanding during the period, including potentially dilutive shares. Potentially dilutive shares include outstanding stock options and restricted stock units ("RSUs"). The dilutive effect of potentially dilutive shares is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in the fair value of the Company's common stock can result in a greater dilutive effect from potentially dilutive shares. The following table presents the calculation of basic and diluted net income per share (in thousands, except per share data):
The following securities were not included in the calculation of diluted shares outstanding as the effect would have been anti-dilutive (in thousands):

| Business Combinations | Business Combinations On January 22, 2016, the Company completed its acquisition of all of the issued and outstanding shares of Inventus, to expand into the litigation discovery services market. The final purchase price for Inventus was approximately $232.0 million, net of working capital adjustments, which the Company paid in January 2016. The following table summarizes the cash paid and the estimated fair values of the assets and the liabilities assumed (in thousands) and the estimated useful lives of the acquired identifiable intangible assets:
The intangible assets acquired are amortized on a straight-line basis which reflects the pattern in which the economic benefits of the intangible assets are expected to be utilized. The goodwill recorded is primarily attributable to the Company's opportunity to expand into the litigation discovery services market and is not deductible for tax purposes. For the nine months ended September 30, 2016, the Company recorded acquisition-related costs of $1.2 million which were expensed as incurred and included in selling, general and administrative expenses in the Company's condensed consolidated statements of operations.

| Debt | Debt On February 26, 2016, the Company entered into a Credit Agreement (the "Credit Agreement") which provided for a $100 million five-year term facility (the "Term Facility") and a $50 million five-year revolving credit facility (the "Revolving Credit Facility"), which remains undrawn as of September 30, 2017. The Term Facility bears interest which is payable quarterly in arrears at the Company's option equal to either a base rate plus a margin ranging from 1.25% to 1.75% per annum or, at the Company's election, the one-, two-, three-, or six-month London interbank offered rate ("LIBOR") plus a margin ranging from 2.25% to 2.75% per annum, based upon the ratio of the Company's debt to consolidated EBITDA ratio. The outstanding balance on the Term Facility bore interest during the nine months ended September 30, 2017 at an average interest rate of 3.5%, which approximates fair value. The Revolving Credit Facility bears a commitment fee on undrawn balances of 0.35% to 0.45% per annum, also based upon the Company's debt to consolidated adjusted EBITDA ratio, that is expensed as incurred. The Credit Agreement contains financial covenants requiring the Company to maintain certain leverage and fixed charge ratios. The Company is compliant with these covenants as of September 30, 2017. The Credit Agreement also includes limitations on the Company's debt incurrence, dividend payments, and disposal activities. As of September 30, 2017, the Term Facility requires principal repayments in accordance with the following schedule (in thousands):

| Commitments and Contingencies Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Commitments and Contingencies | Commitments and Contingencies Commitments The Company generally does not enter into long-term minimum purchase commitments. Its principal long-term commitments consist of obligations under operating leases for office space. In June 2017, the Company executed an amendment to its operating lease for its corporate headquarters in San Francisco. In accordance with the amendment, effective August 2017, the Company reduced its leased space by approximately 18,000 square feet of the approximately 67,000 square feet of total previously leased space, which reduces the Company's future operating lease commitments by approximately $2.4 million over the remaining lease term. Other than this change to the Company's lease obligation for its corporate headquarters, there were no material changes to the Company’s contractual obligations or commitments during the nine months ended September 30, 2017 as compared to those presented under the heading “Commitments and Contingencies” in Note 12 of the Notes to Consolidated Financial Statements in Part II, Item 8 of the Company’s Annual Report on Form 10-K filed with the SEC on February 28, 2017. The following table summarizes rent expense related to non-cancelable operating leases (in millions):
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 September 30, 2017 or December 31, 2016. In April 2016, Sourceprose Corporation filed a complaint in the U.S. District Court for the Western District of Texas against the Company alleging breach of an agreement with the plaintiff to purchase certain patent assets and breach of a non-disclosure agreement with plaintiff. In July 2016, the Court transferred the litigation to the U.S. District Court for the Northern District of California. In November 2016, the Company moved to dismiss the claims of breach of an assignment of patents. In January 2017, the U.S. District Court for the Northern District of California dismissed the claims of breach of a patent assignment without prejudice, and allowed the plaintiff to file an amended complaint. The plaintiff filed an amended complaint in February 2017, alleging breach of a non-disclosure agreement, breach of an agreement to assign patents and a breach of a settlement agreement. In March 2017, the Company moved to dismiss all of the plaintiff’s claims, and the court granted-in-part and denied-in-part the motion, allowing the plaintiff leave to amend the complaint. The plaintiff filed a third amended complaint in May 2017, again alleging breach of an agreement with the plaintiff to purchase certain patent assets and breach of a non-disclosure agreement. RPX answered the third amended complaint in June 2017, and the case proceeded to the discovery phase. As of September 30, 2017, the Company was not able to determine the potential loss that may have resulted from this litigation. In October 2017, the parties agreed to a confidential settlement pursuant to which all claims were subsequently dismissed. The settlement does not have a material impact to the Company's financial condition or results of operations. In June 2013, Kevin O’Halloran, as Trustee of the Liquidating Trust of Tectonics, 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. In February 2015, the Court held a trial and in November 2015 entered judgment in favor of the Defendants. In December 2015, the Debtor filed an appeal of the judgment to the U.S. District Court for the Middle District of Florida. In August 2016, the District Court affirmed the judgment in favor of the Defendants. In September 2016, the Debtor filed an appeal of the judgment to the U.S. Court of Appeals for the Eleventh Circuit. The appellate briefing was completed in January 2017, and the oral argument is scheduled for December 14, 2017. 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 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. In April 2016, the Court entered a final judgment in favor of the Defendants on all the plaintiff's claims. In April 2016, the plaintiff filed an appeal of the judgment. The appellate briefing was completed in November 2016, and oral argument is scheduled for November 14, 2017. 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. No liability was recorded for these agreements as of September 30, 2017 or December 31, 2016. 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. As part of the Company's discovery services offering, the Company generally warrants that it will perform the services in good faith and in a timely and professional manner, and that it will exercise the same level of professional care commonly found in the industry. Additionally, the Company has agreed to provisions for indemnifying customers against liabilities if its discovery services infringe a third party’s intellectual property rights or if it breaches agreed privacy, security and/or confidentiality obligations. To date, the Company has not incurred any material costs, and it has not accrued any liabilities in the accompanying condensed consolidated financial statements, as a result of these obligations. The Company also enters into service-level agreements with its discovery services clients that specify required levels of application uptime and may permit customers to receive credits or to terminate their agreements in the event that the Company fails to meet required performance levels. To date, the Company has not experienced any significant failures to meet defined levels of performance and, as a result, has not accrued any liabilities related to these agreements in its condensed consolidated financial statements. 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 The Company offers patent litigation insurance that covers certain costs associated with patent infringement lawsuits, and it assumes a portion of the underwriting risk on these insurance policies that it issues on behalf of a Lloyd's of London underwriting syndicate. As of September 30, 2017 and December 31, 2016, the Company recorded a reserve of $1.2 million and $0.9 million, respectively, for known and incurred but not reported claims that represent estimated claim costs and related expenses for the policies underwritten and its portion of the underwriting risk on policies that the Company issued on behalf of the Lloyd's of London underwriting syndicate. The Company regularly reviews loss reserves using a variety of actuarial techniques and updates them as its loss experience develops. |

| Stockholders' Equity | Stockholders’ Equity Equity Plans 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):
(1) In the first quarter of 2017, the Company reserved an additional 1.0 million shares of its common stock for future issuance under the 2011 Plan. The aggregate intrinsic value of stock options exercised during the three months ended September 30, 2017 and 2016 was $0.2 million and $0.5 million, respectively, and $2.8 million and $0.8 million for stock options exercised during the nine months ended September 30, 2017 and 2016, respectively. The total grant date fair value of stock options vested during the three months ended September 30, 2016 was $0.2 million, and $1.2 million for stock options vested during the nine months ended September 30, 2016. No stock options vested during the three or nine months ended September 30, 2017, and as of September 30, 2017, all options issued and outstanding were fully vested. Restricted Stock Units The summary of RSU activity, which includes performance-based restricted stock units (“PBRSUs”), is as follows (in thousands, except per share data):
The total grant date fair value of RSUs vested during the three months ended September 30, 2017 and 2016 was $3.7 million and $2.9 million, respectively, and $13.1 million and $9.0 million during the nine months ended September 30, 2017 and 2016, respectively. In October 2013, the Board of Directors approved net-share settlement for tax withholdings on RSU vesting. During the nine months ended September 30, 2017, the Company withheld issuing 361,376 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 to taxing authorities for employees’ minimum tax obligations were $4.5 million for the nine months ended September 30, 2017, and were recorded as a reduction to additional paid-in capital and reflected as a financing activity within the condensed 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 fair value of RSUs granted to employees and directors is measured by reference to the fair value of the underlying shares on the date of grant. PBRSUs granted during the nine months ended September 30, 2017 and 2016 contain service, performance, and/or market conditions that affect the quantity of awards that will vest. During the nine months ended September 30, 2017 and 2016, the Company granted 102,790 and 115,657 PBRSUs, respectively. The Company estimates the grant date fair value of PBRSUs which include market conditions using the Monte Carlo simulation model. The weighted-average assumptions used to estimate the fair value of PBRSUs with market conditions and the resulting fair values are as follows:
Stock-based compensation expense related to stock options granted to employees and directors was nil and $0.1 million for the three months ended September 30, 2017 and 2016, respectively, and nil and $0.9 million for the nine months ended September 30, 2017 and 2016, respectively. Stock-based compensation expense related to PBRSUs and RSUs granted to employees and directors was $3.8 million and $4.2 million for the three months ended September 30, 2017 and 2016, respectively, and $10.9 million and $13.3 million for the nine months ended September 30, 2017 and 2016, respectively. As of September 30, 2017, there was $31.9 million of unrecognized compensation cost related to RSUs, including PBRSUs, which is expected to be recognized over a weighted-average period of 2.6 years. Future grants of equity awards will increase the amount of stock-based compensation expense to be recorded. Stock Repurchase Program On February 10, 2015, the Company announced that its Board of Directors had authorized a share repurchase program under which the Company is authorized to repurchase up to $75.0 million of its outstanding common stock with no expiration date from the date of authorization. In March 2016 and May 2016, the Company increased its share repurchase program by $25.0 million and $50.0 million, respectively, for a total amount authorized of $150.0 million. As of September 30, 2017, the Company repurchased $92.9 million of the outstanding common stock. Under the program, shares may be purchased in open market transactions, including through block purchases, through privately negotiated transactions, or pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The share repurchase program does not have an expiration date and may be suspended, terminated, or modified at any time for any reason. The Company’s share repurchase program does not obligate it to acquire any specific number of shares. The Company repurchased shares of its common stock in the open market, which were retired upon repurchase. The purchase price for the repurchased shares is reflected as a reduction to common stock and retained earnings in the Company's condensed consolidated balance sheet. Share repurchase activity during the period presented was as follows (in thousands, except per share data):

| Segment Reporting | Segment Reporting Operating segments are components of an enterprise about which separate financial information is available. Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is its Chief Executive Officer. Prior to the acquisition of Inventus in January 2016, the Company’s Chief Executive Officer reviewed financial information presented on a consolidated basis and, as a result, the Company concluded that there was only one operating and reportable segment at that time. Subsequent to the acquisition of Inventus (see Note 7, Business Combinations), the Company's Chief Executive Officer reviews separate financial information for the patent risk management and discovery services businesses. Therefore, as of January 2016, the Company has two reportable segments: 1) patent risk management which generates its revenues primarily from membership subscriptions, premiums earned from insurance policies, and management fees for marketing, underwriting, and claim management and 2) discovery services which generates its revenues primarily from fees generated for data collection, hosting and processing, project management, and document review services. There are no material internal revenue transactions between these two reportable segments. Although adjusted EBITDA is not a measure of financial performance determined in accordance with GAAP, the Company's chief operating decision maker evaluates segment financial performance by utilizing the segment's adjusted EBITDA because the Company believes it is a useful supplemental measure that reflects core operating performance and provides an indicator of the segment's ability to generate cash. The Company defines adjusted EBITDA as net income exclusive of provision for income taxes, interest and other income (expense), net, stock-based compensation and related employer payroll taxes, depreciation, and amortization. There are limitations in using the Company's measures of financial performance that are not determined in accordance with GAAP and these may be different from other financial measures not determined in accordance with GAAP used by other companies. These financial measures are limited in value because they exclude certain items that may have a material impact on the Company's reported financial results. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by the Company about which items are adjusted to calculate its financial measures not determined in accordance with GAAP. The presentation of financial measures not determined in accordance with GAAP should not be considered in isolation or as a substitute for, or superior to, financial results determined in accordance with GAAP. Summarized financial information by segment utilized by the Company's chief operating decision maker is as follows (in thousands):
The following table reconciles the Company's subtotal segment adjusted EBITDA to consolidated net income (in thousands):

| Accounting Policies [Abstract] | |
| Basis of Presentation | Basis of Presentation The accompanying condensed consolidated balance sheet as of September 30, 2017, the condensed consolidated statements of operations and the condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2017 and 2016, and the condensed consolidated statements of cash flows for the nine months ended September 30, 2017 and 2016, are unaudited. The condensed consolidated balance sheet as of December 31, 2016 was derived from the audited consolidated financial statements which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016, which was filed with the U.S. Securities and Exchange Commission (“SEC”) on February 28, 2017. The unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America and with the instructions for Form 10-Q and Regulation S-X for interim financial statements. Accordingly, they do not include all of the information and notes required for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring items, necessary to state fairly the results of the interim periods have been included in the accompanying financial statements. Operating results for the three or nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for any subsequent interim period or for the year ending December 31, 2017. |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09") which clarifies the changes to terms or conditions of a share-based payment award that require an entity to apply modification accounting. ASU 2017-09 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. Early application is permitted and prospective application is required. The Company is currently evaluating impact of this guidance on its consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities (“ASU 2017-08”), which shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public entities, ASU 2017-08 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements. In February 2017, the FASB issued ASU No. 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets: Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets. This ASU was issued to clarify the scope of the previous standard and to add guidance for partial sales of nonfinancial assets and is effective for fiscal years and interim periods within those years beginning after December 15, 2017. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment, which simplifies the subsequent measurement of goodwill and eliminates the two-step goodwill impairment test. Under the new guidance, an annual or interim goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The amendment also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and two-step goodwill impairment test. The ASU is effective prospectively for fiscal years and interim periods within those years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company will early adopt this ASU for goodwill impairment tests beginning in 2017. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations: Clarifying the Definition of a Business, which provides a more robust framework to use in determining when a set of assets and activities is a business. This ASU is effective prospectively for fiscal years and interim periods within those years beginning after December 15, 2017. The Company will apply this guidance to applicable transactions after the adoption date. The FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as well as associated ASUs 2016-08, 2016-10, 2016-12, 2016-20, 2017-13 (the foregoing ASUs collectively, "Topic 606"), which will supersede most existing revenue recognition guidance in U.S. GAAP. Topic 606 becomes effective for annual and interim periods beginning after December 15, 2017; early adoption is permitted for annual and interim periods beginning after December 15, 2016. The Company plans to adopt Topic 606 on January 1, 2018, using the full retrospective method of adoption. This standard will have a material effect on the Company's consolidated financial statements due to the identification of multiple performance obligations from its patent risk management membership subscription and the timing of recognition for these separable performance obligations. Specifically, the Company will recognize separate performance obligations under Topic 606 for certain discrete patent assets transferred to its membership clients as well as for access to the Company's patent portfolio clients obtain when becoming a member or renewing membership. The revenue generated from these additional performance obligations will be recognized at a point in time. Under existing U.S. GAAP, the Company generally recognizes the membership fees ratably on a gross basis over the term of the customer contract. Therefore, the adoption of Topic 606 may increase the variability of the revenue recognized from the Company's patent risk management services from period to period. The Company will determine whether revenue should be recognized on a gross or net basis under Topic 606, which may result in revenue which is recognized on a gross basis under current U.S. GAAP to be recognized on a net basis under Topic 606 due to the additional separable performance obligations. Additionally, based on the Company's initial assessment, it does not expect Topic 606 to have a material impact on its discovery services segment. |
