Exhibit 10.15

AMENDED AND RESTATED VOTING AGREEMENT

This AMENDED AND RESTATED VOTING AGREEMENT (the “Agreement”) is made and entered into as of July 15, 2009, by and among RPX Corporation, a Delaware corporation (the “Company”), the holders of the Company’s Series A Preferred Stock (the “Series A Stock”), Series A-1 Preferred Stock (the “Series A-1 Stock”) and Series B Preferred Stock (the “Series B Stock” and collectively with the Series A Stock and Series A-1 Stock, the “Preferred Stock”), listed on the Schedule of Investors attached as Schedule A hereto (together with any subsequent investors, or transferees, who become parties hereto as “Investors” pursuant to Section 19 below, the “Investors”), and the holders of Common Stock of the Company (the “Founders”) listed on the Schedule of Founders attached as Schedule B hereto. The Company, the Founders and the Investors are individually referred to herein as a “Party” and are collectively referred to herein as the “Parties.” The Company’s Board of Directors is referred to herein as the “Board.”

WITNESSETH:

WHEREAS, the Company and certain of the Investors have entered into that certain Series B Preferred Stock Purchase Agreement dated as of July 1, 2009 (the “Purchase Agreement”), which provides for, among other things, the purchase by the Investors of shares of the Series B Stock;

WHEREAS, the Company, the holders of Series A Stock and Series A-1 Stock, and the Founders have previously entered into that certain Voting Agreement dated as of August 12, 2008 (the “Prior Agreement”) and desire to amend and restate the Prior Agreement and to accept the rights created pursuant hereto in lieu of the rights created under the Prior Agreement; and

WHEREAS, to induce the Investors to enter into the Purchase Agreement and purchase shares of Preferred Stock thereunder, the Company and the Founders desire to enter into this Agreement with such Investors;

NOW, THEREFORE, in consideration of the foregoing premises and certain other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

1. Agreement to Vote. Each Investor hereby agrees on behalf of itself and any transferee or assignee of any shares of voting securities of the Company, to hold all of such shares registered in its name (and any securities of the Company issued with respect to, upon conversion of, or in exchange or substitution of such shares, and any other voting securities of the Company subsequently acquired by such Investor) (hereinafter collectively referred to as the “Investor Shares”) subject to, and to vote the Investor Shares at a regular or special meeting of stockholders (or by written consent) in accordance with, the provisions of this Agreement. Each Founder hereby agrees on behalf of itself and any transferee or assignee of any shares of voting securities of the Company, to hold all of such shares and any other securities of the Company acquired by such Founder in the future (and any securities of the Company issued with respect

to, upon conversion of, or in exchange or substitution for such securities) (the “Founder Shares,” and together with the “Investor Shares,” the “Shares”) subject to, and to vote the Founder Shares at a regular or special meeting of stockholders (or by written consent) in accordance with, the provisions of this Agreement.

2. Board Size. Subject to Section 3(a) below, the holders of Shares shall vote at a regular or special meeting of stockholders (or by written consent) such shares that they own (or as to which they have voting power) to ensure that the size of the Board shall be set and remain at seven (7) directors (the “Board Size”).

3. Election of Directors.

(a) In any election of directors of the Company, the Parties shall each vote at any regular or special meeting of stockholders (or by written consent) such number of Shares then owned by them (or as to which they then have voting power) as may be necessary to elect three (3) directors nominated by the holders of a majority of the then outstanding shares of Common Stock held by the Founders (the “Common Directors”), who shall initially be Xxxx Xxxxxx, Xxxxxxxx X. Xxxxxx and Xxxx Xxx; provided, however, that the number of directors elected pursuant to this Section 3(a) shall be reduced by one (1) director for each Founder whose service to the Company as an employee or consultant is terminated; provided further, however, that the number of Common Directors elected pursuant to this Section 3(a) shall in no event be reduced below one (1). In the event the number of Common Directors is reduced pursuant to the terms of this Section 3(a), the Board Size shall likewise be reduced by the same number of directors and the Investors and the Founders each hereby agree to vote at any regular or special meeting of stockholders (or by written consent) such number of voting securities of the Company then owned by them (or as to which they then have voting power) as may be necessary to amend this Agreement to appropriately reflect such decrease in the Board Size.

(b) In any election of directors of the Company, the Parties shall each vote at any regular or special meeting of stockholders (or by written consent) such number of Shares then owned by them (or as to which they then have voting power) as may be necessary to elect as the “Preferred Directors,” as that term is defined in the Amended and Restated Certificate of Incorporation of the Company (as amended from time to time, the “Restated Certificate”), (i) one (1) director nominated by KPCB Holdings, Inc. or its affiliates (“KPCB”), who shall initially be Xxxxx Xxxxxxx, (ii) one (1) director nominated by Xxxxxxx River Ventures, LLC or its affiliates (“CRV”), who shall initially be Xxxxx Xxxxxx, and (iii) one (1) director nominated by Index Ventures Growth I (Jersey), L.P. or its affiliates (“Index”), who shall initially be Xxxxxxxx Xxxxx (collectively, the “Preferred Directors”).

(c) In any election of directors of the Company, the holders of shares of Common Stock and holders of shares of Preferred Stock (on an as-converted to Common Stock basis), voting together as a class, shall have the right to elect one (1) director (the “Mutual Director”). The Parties shall each vote at any regular or special meeting of stockholders (or by written consent) such number of Shares then owned by them (or as to which they then have voting power) as may be necessary to elect a Mutual Director that is approved by a majority of the Common Directors then in office and a majority of the Preferred Directors then in office.

2

4. Removal. Any director of the Company may be removed from the Board in the manner allowed by law and the Restated Certificate and Bylaws, but with respect to a director designated pursuant to subsections 3(a), 3(b) and 3(c) above, only upon the vote or written consent of the stockholders entitled to designate such director. In the event that any Party or Parties entitled to designate a director pursuant to Section 3 above shall notify the Company of a desire to remove or change from the Board the incumbent director who occupies the Board seat that such Party or Parties are entitled to designate, the Company shall take such reasonable actions as are necessary to facilitate such removals and/or elections, including, without limitation, soliciting the votes of the appropriate stockholders, and the Parties shall vote their Shares to cause: (a) the removal from the Board of the director so designated for removal; and (b) the election to the Board of any new designee so designated.

5. Certificate of Incorporation. In the event that the Company has determined that it is necessary to increase the number of authorized but unissued shares of Common Stock to a number of shares sufficient to provide for the conversion of all outstanding shares of Preferred Stock in accordance with the terms of the Restated Certificate, each Party to this Agreements agrees to vote its Shares in favor of an amendment to the Restated Certificate that effects such increase in the number of authorized shares of Common Stock.

6. Legend on Share Certificates. Each certificate representing any Investor Shares or Founder Shares shall be endorsed by the Company with a legend reading substantially as follows:

“THE SHARES EVIDENCED HEREBY ARE SUBJECT TO A VOTING AGREEMENT (A COPY OF WHICH MAY BE OBTAINED UPON WRITTEN REQUEST FROM THE ISSUER), AND BY ACCEPTING ANY INTEREST IN SUCH SHARES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF SAID VOTING AGREEMENT.”

7. Covenant of the Company. The Company will not, by any voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be performed hereunder by the Company.

8. No Liability for Election of Recommended Directors. Neither the Company, the Founders, the Investors, nor any officer, director, stockholder, partner, employee or agent of any such Party, makes any representation or warranty as to the fitness or competence of the nominee of any Party hereunder to serve on the Company’s Board by virtue of such Party’s execution of this Agreement or by the act of such Party in voting for such nominee pursuant to this Agreement.

9. Grant of Proxy. Upon the failure of any Party to vote their Investor Shares or Founder Shares, as applicable, in accordance with the terms of this Agreement within five (5) days of its receipt (as determined pursuant to Section 13 hereof) of the Company’s request to do so, such Party hereby grants to a stockholder designated by the Board of Directors of the Company a proxy coupled with an interest in all Investor Shares and Founder Shares owned by such Party, which proxy shall be irrevocable until this Agreement terminates pursuant to its

3

terms or this Section 9 is amended to remove such grant of proxy in accordance with Section 16 hereof, to vote all such Investor Shares and Founder Shares in the manner provided in Sections 2 and 3 hereof.

10. Specific Enforcement. It is agreed and understood that monetary damages would not adequately compensate an injured Party for the breach of this Agreement by any other Party, that this Agreement shall be specifically enforceable, and that any breach or threatened breach of this Agreement shall be the proper subject of a temporary or permanent injunction or restraining order. Further, each Party hereto waives any claim or defense that there is an adequate remedy at law for such breach or threatened breach.

11. Execution by the Company. The Company, by its execution in the space provided below, agrees that it will cause the certificates issued after the date hereof evidencing the shares of Investor Shares and Founder Shares to bear the legend required by Section 6 hereof, and it shall supply, free of charge, a copy of this Agreement to any holder of a certificate evidencing shares of capital stock of the Company upon written request from such holder to the Company at its principal office. The parties hereto do hereby agree that the failure to cause the certificates evidencing the shares of Investor Shares and Founder Shares to bear the legend required by Section 6 hereof and/or failure of the Company to supply, free of charge, a copy of this Agreement, as provided under this Section 11, shall not affect the validity or enforcement of this Agreement.

12. Captions. The captions, headings and arrangements used in this Agreement are for convenience only and do not in any way limit or amplify the terms and provisions hereof.

18. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

19. Binding Effect. In addition to any restriction on transfer that may be imposed by any other agreement by which any Party hereto may be bound, this Agreement shall be binding upon the Parties, their respective heirs, successors, transferees and assigns and to such additional individuals or entities that may become stockholders of the Company and that desire to become Parties hereto; provided that for any such transfer to be deemed effective, the transferee shall have executed and delivered an Adoption Agreement substantially in the form attached hereto as Exhibit A. Upon the execution and delivery of an Adoption Agreement by a transferee reasonably acceptable to the Company, such transferee shall be deemed to be a Party hereto as if such transferee’s signature appeared on the signature pages hereto.
