RPX Corporation (NASDAQ: RPXC) is a leading provider of patent risk solutions, offering defensive buying, acquisition syndication, patent intelligence, insurance services, and advisory services. Since its founding in 2008, RPX has introduced efficiency to the patent market by providing a rational alternative to litigation. The San Francisco-based company's pioneering approach combines principal capital, deep patent expertise, and client contributions to generate enhanced patent buying power. By acquiring patents, RPX helps to mitigate and manage patent risk for its growing client network. 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. As of September 30, 2012, RPX had invested over $500 million to acquire more than 2,950 US and international patent assets and rights, and had a client network of 128 members active in seven key sectors: consumer electronics and PCs, E-commerce and software, financial services, media content and distribution, mobile communications and devices, networking, and semiconductors. RPX promises it will never assert patents or patent rights in its portfolio.
