RPX Client Network Grows to 103 Companies

SAN FRANCISCO, Nov. 1, 2011 (GLOBE NEWSWIRE) -- RPX Corporation (Nasdaq:RPXC), the leading provider of patent risk management solutions, today announced that its client network grew to 103 member companies as of September 30, 2011, representing a diverse array of technology sectors including consumer electronics and PCs, e-commerce and software, media content and distribution, mobile communications and devices, networking, and semiconductors.

A partial list of new clients added in the second and third quarters of 2011 includes: Advanced Micro Devices, Inc., Avaya Inc., Ericsson AB, Vivitek Corporation's parent Luxeon International Holding LTD, MobiTV, Inc., Nikon Corporation, Pantech Co., Ltd., Pioneer Corporation, and WowWee Group Limited.

RPX combines principal capital with annual fees from its client network to acquire potentially dangerous patents in an array of technology categories important to its clients, removing them from circulation in the open market before they can be used offensively by NPEs. In recent years, NPEs have raised billions of dollars to buy and assert patents. RPX clients pay annual fees ranging from $60,000 to $6.6 million depending on company size, and automatically receive rights to the entire RPX patent portfolio. RPX will never assert patents or patent rights in its portfolio.
