Re: RPX Corporation
     Amendment No. 1 to Registration Statement on Form S-1
     File No. 333-171817

Dear Mr. Rothenberg:

RPX Corporation (the “Company”) electronically transmitted via EDGAR Amendment No. 1 (“Amendment No. 1”) to its Registration Statement on Form S-1 (the “Registration Statement”) on March 4, 2011. The Company has discovered that the Company’s Consolidated Statements of Cash Flows on Page F-6 of Amendment No. 1 contains an administrative error. Under the heading “Cash flows from operating activities,” Amendment No. 1 includes a line item titled “Utilization of deferred tax asset” that was included due to administrative error and should have been deleted.

Enclosed with this letter is a copy of Page F-6 as it should read. The Company confirms that it will not be marketing its offering with a copy of the prospectus that includes the administrative error and will correct the error in the next amendment to the Registration Statement.

Please do not hesitate to contact me at (650) 463-5244, if you have any questions or would like additional information regarding this matter.

Very truly yours,

GUNDERSON DETTMER STOUGH

VILLENEUVE FRANKLIN & HACHIGIAN, LLP
