Terms were not disclosed. RPX’s service will be announced in October 2008. “RPX helps technology and e-commerce leaders protect themselves from intellectual property litigation so they can focus on patent development rather than patent defense,” said John Doerr, partner at KPCB. More than 1,500 patent infringement lawsuits were filed in the United States in the first half of 2008 - many with multiple defendants. Average estimated litigation costs are approximately $4.5 million, according to a 2005 American Intellectual Property Law Association survey. These lawsuits cost operating companies billions of dollars annually. Total costs to companies are far higher when factoring in costs of non-litigation assertions and settlements. "As an early investor in the patent commerce market, we are impressed with RPX’s management team, how their business model complements other models in the market, and their opportunity to address the patent assertion and litigation problems for major companies," said Izhar Armony a general partner at CRV. RPX co-CEO John Amster said, “Patent assertion and litigation costs U.S. businesses billions of dollars every year. Our goal was to create an affordable service model that reduces the threat of assertion and litigation and provides efficient patent protection to subscribing companies.” About Kleiner Perkins Caufield & Byers Since its founding in 1972, Kleiner Perkins Caufield & Byers has backed entrepreneurs in over 500 ventures, including AOL, Amazon.com, Citrix, Compaq Computer, Electronic Arts, Genentech, Genomic Health, Google, Intuit, Juniper Networks, Netscape, Lotus, Sun Microsystems, Symantec, Verisign and Xilinx.
