| 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-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”). In March 2014, the Company formed a reinsurance company to assume some portion of the underwriting risk on insurance policies that the Company issues on behalf of a Lloyd’s of London underwriting syndicate. The Company began placing new policies under the reinsurance model in May 2014. As of, and for the three months ended March 31, 2015, the effect of the insurance policies that the Company has issued or assumed through our reinsurance business was not material to the Company’s results of operations, financial condition or cash flows. |

| 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 March 31, 2015, the condensed consolidated statements of operations, the condensed consolidated statements of comprehensive income and the condensed consolidated statements of cash flows for the three months ended March 31, 2015 and 2014, are unaudited. The condensed consolidated balance sheet as of December 31, 2014 was derived from the audited consolidated financial statements which are included in the Company’s Form 10-K for the fiscal year ended December 31, 2014, which was filed with the U.S. Securities and Exchange Commission (“SEC”) on March 2, 2015. 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, 2014. 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 months ended March 31, 2015 are not necessarily indicative of the results that may be expected for any subsequent interim period or for the year ending December 31, 2015. Recently Adopted Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which will supersede most existing revenue recognition guidance in U.S. generally accepted accounting principles (“U.S. GAAP”) once it becomes effective. ASU 2014-09 requires an entity to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 will be effective for annual and interim periods beginning after December 15, 2016 and early adoption is not permitted. The Company is currently evaluating the impact of the adoption of ASU 2014-12 on its consolidated financial statements. Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the three months ended March 31, 2015, 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 March 2, 2015. |

| Fair Value Measurements | The following tables present the Company's financial assets and liabilities measured at fair value on a recurring basis (in thousands):
The Company's short-term investments in Level 2 equity securities are classified as held-to-maturity with the remainder of the Company's short-term investments classified as available-for-sale. Available-for-sale and held-to-maturity securities are reported at fair value, with unrealized gains and losses, net of tax, included as a separate component of stockholders’ equity within accumulated other comprehensive income (loss). Realized gains and losses on these securities are included in other income, net in the Company’s condensed consolidated statements of operations and have not been material for all periods presented. The weighted-average remaining maturity of the Company’s financial assets and liabilities was less than one year as of March 31, 2015 and December 31, 2014. As of March 31, 2015, no individual securities incurred continuous unrealized losses for greater than 12 months. In connection with the Rockstar Transaction (see Note 9, "Commitments and Contingencies"), the Company received funding of $6.3 million from a syndicate participant. At March 31, 2015, the fair value of the loan from the syndicate participant was $4.4 million and was categorized as Level 3. Level 3 Valuation Techniques Level 3 financial liabilities consist of repayment obligations to a third party for which determination of fair value requires significant judgment and estimation. Changes in fair value measurement categorized within Level 3 of the fair value hierarchy are analyzed each period for changes in estimates or assumptions and recorded as appropriate. The Company uses the Black-Scholes option valuation model to value certain Level 3 financial liabilities at inception and subsequent valuation dates. This model incorporates assumptions about details such as the value of underlying securities, expected terms, maturity, risk-free interest rates, as well as volatility. A significant change in volatility and expected term could result in a significant change in fair value. The risk-free interest rate was based on the implied yield currently available on U.S. Treasury zero coupon issues with an equivalent remaining term at the measurement date. The expected volatility was calculated using the standard deviation of the underlying security's daily returns over the estimated period of time to take to settle the liability. The expected term of the liability is determined by the estimated settlement date of the liability. Changes in the values are recorded in the Company's statement of operations. As of March 31, 2015, there were no transfers in or out of Level 3 from other levels of the fair value hierarchy. |

| Patent Assets, Net [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Patent Assets, Net | 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 March 31, 2015, the estimated economic useful lives of the Company’s patent assets generally ranged from 24 to 60 months. As of March 31, 2015, the weighted-average estimated economic useful life at the time of acquisition of all patents acquired since the Company’s inception was 45 months. As of March 31, 2015, the Company expects amortization expense in future periods to be as follows (in thousands):
Amortization expense was $33.1 million and $27.6 million for the three months ended March 31, 2015 and 2014, respectively. On December 22, 2014, the Company and RPX Clearinghouse LLC (a wholly-owned subsidiary of the Company) entered into an Asset Purchase Agreement by and among Rockstar Consortium US LP, Rockstar Consortium LLC, Bockstar Technologies LLC, Constellation Technologies LLC, MobileStar Technologies LLC, and NetStar Technologies LLC (the “Sellers”), for the purchase of substantially all of the patent assets owned or controlled by the Sellers (the “Rockstar Transaction”), as well as other ancillary agreements, including but not limited to an Escrow Agreement by and among the Sellers, Citibank, N.A., acting as escrow agent, RPX Clearinghouse LLC and the Company (the “Escrow Agreement”). Upon the closing of the Rockstar Transaction, syndicate participants received non-exclusive licenses to the patent assets included in the Rockstar Transaction, and RPX Clearinghouse made the patent assets available for license to all other interested companies under fair, reasonable, and non-discriminatory terms. RPX Clearinghouse LLC paid the Sellers $25.0 million as a non-refundable deposit on December 26, 2014 upon the execution of the Asset Purchase Agreement. The third-party funding commitments described below were derived pursuant with the Escrow Agreement and the remaining closing conditions under the Asset Purchase Agreement were met on January 28, 2015 on which date the Rockstar Transaction was consummated and the Sellers received an additional payment of $875.0 million from escrow. RPX Clearinghouse LLC received funding commitments for the Rockstar Transaction from a syndicate of more than 30 companies. The Company evaluated the contributions from syndicate members to determine whether they should be recorded on a gross or net basis. As a result, the Company accounted for these third-party funding commitments on a net basis as it acted as an agent to acquire patent rights from the Sellers on behalf of the syndicate who paid for such rights separately from a subscription agreement. The Company contributed approximately $29.0 million which was recorded as a patent asset upon closing of the Rockstar Transaction and is amortized over its estimated economic useful life of 60 months. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments And Contingencies | Commitments and Contingencies Operating Lease 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. There were no substantial changes to the Company’s contractual obligations or commitments during the three months ended March 31, 2015 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 March 2, 2015. Rent expense related to non-cancelable operating leases was $0.9 million for each of the three months ended March 31, 2015 and 2014, net of sublease income of $0.2 million and $0.1 million, respectively. Deferred Payment Obligations In connection with the Rockstar Transaction (see Note 5, "Patent Assets, Net"), the Company acquired certain common stock, convertible preferred stock, and redeemable convertible preferred stock investments held by the Seller. To fund the acquisition of these securities, the Company received funding of $6.3 million from a syndicate participant and seller financing of $5.9 million. These amounts are considered loans in the Company's condensed consolidated balance sheets and are recorded as current liabilities as they are expected to be repaid within 12 months. The loan received from the syndicate participant bears no interest and is repayable upon the sale of the common stock and convertible preferred stock securities. The amount repayable under this loan is limited to the proceeds received from the sale of the common and convertible preferred stock securities, up to a maximum amount of $6.3 million. The Company has elected to carry this loan at fair value and changes are reported in other income, net in the Company's condensed consolidated statements of operations. At March 31, 2015, the fair value of the loan was $4.4 million and was categorized as a Level 3 due to the significance of unobservable inputs developed using company-specific information. A gain of $0.1 million was recognized in the condensed consolidated statement of operations during the three months ended March 31, 2015 as a result of the changes in fair value of this loan and corresponding securities. The loan received from the Seller is carried at cost, bears no interest, and is repayable upon redemption or conversion of the redeemable convertible preferred stock. At March 31, 2015, the loan was recorded at $5.9 million. 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 March 31, 2015 or December 31, 2014. 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 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 we terminated our 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 March 2014, the Court entered an order staying the litigation pending the resolution of related litigation in the U.S. District Court for the Northern District of Illinois, and has subsequently continued the stay until July 2015. We are not currently able to determine whether there is a reasonable possibility that a loss has been incurred, nor can we 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. The Company had no liabilities recorded for these agreements as of March 31, 2015 or December 31, 2014. 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 March 31, 2015, the Company had a total of 57 active policies and had recorded a reserve of $0.9 million for known and incurred but not reported claims that represent estimated claim costs and related expenses. The Company regularly reviews its 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 March 2015, the Company reserved an additional 1,000,000 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 March 31, 2015 and 2014 was $1.6 million and $1.7 million, respectively. The total fair value of stock options vested during the three months ended March 31, 2015 and 2014 was $0.9 million and $1.7 million, respectively. Restricted Stock Units The summary of restricted stock unit activity, which includes performance-based restricted stock units with a market condition (“PBRSUs”), is as follows (in thousands, except per share data):
The total fair value of restricted stock units (“RSUs”) vested during the three months ended March 31, 2015 and 2014 was $2.3 million and $2.4 million, respectively. In October 2013, the Board of Directors approved net-share settlement for tax withholdings on RSU vesting. During the three months ended March 31, 2015, the Company withheld issuing 60,742 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 employees’ minimum tax obligations to taxing authorities were $0.9 million for the three months ended March 31, 2015, 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 contain both service and market conditions that affect the quantity of awards that will vest. During the three months ended March 31, 2015 and 2014, the Company granted nil and 200,000 PBRSUs, respectively. The Company estimates the grant date fair value of 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 directors was $0.7 million and $1.5 million for the three months ended March 31, 2015 and 2014, respectively. Stock-based compensation expense related to RSUs granted to employees and directors was $3.0 million and $2.2 million for the three months ended March 31, 2015 and 2014, respectively. Stock-based compensation expense related to PBRSUs granted to employees was $0.1 million and $0.2 million for the three months ended March 31, 2015 and 2014, respectively. As of March 31, 2015, there was $3.2 million and $36.2 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 1.2 years and 3.0 years, respectively. 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 has 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. As of March 31, 2015, $0.3 million of the $75.0 million had been utilized. 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, or 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, during the period presented as follows (in thousands, except per share data):

| Basis of Presentation | Basis of Presentation The accompanying condensed consolidated balance sheet as of March 31, 2015, the condensed consolidated statements of operations, the condensed consolidated statements of comprehensive income and the condensed consolidated statements of cash flows for the three months ended March 31, 2015 and 2014, are unaudited. The condensed consolidated balance sheet as of December 31, 2014 was derived from the audited consolidated financial statements which are included in the Company’s Form 10-K for the fiscal year ended December 31, 2014, which was filed with the U.S. Securities and Exchange Commission (“SEC”) on March 2, 2015. 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, 2014. 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 months ended March 31, 2015 are not necessarily indicative of the results that may be expected for any subsequent interim period or for the year ending December 31, 2015. Recently Adopted Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which will supersede most existing revenue recognition guidance in U.S. generally accepted accounting principles (“U.S. GAAP”) once it becomes effective. ASU 2014-09 requires an entity to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 will be effective for annual and interim periods beginning after December 15, 2016 and early adoption is not permitted. The Company is currently evaluating the impact of the adoption of ASU 2014-12 on its consolidated financial statements. Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the three months ended March 31, 2015, 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 March 2, 2015. |
