Xerox Files Patent Suit Against Google, Yahoo [informationweek.com]

Xerox Corporation on Friday filed a patent infringement lawsuit against Google, Yahoo, and YouTube over disputed Internet search and e-commerce technology. The document management company alleges that Google has infringed upon its patent "System for automatically generating queries" with its AdWords and AdSense software. It also claims that Google Maps and Google video violate a different patent, "Method and apparatus for the integration of information and knowledge," which has to do with updating Web pages based on user reviews. Yahoo, Xerox claims, has infringed on its query patent with Yahoo Search Marketing, Yahoo Publisher Network and Y!Q Contextual Search. And the company further claims that Yahoo Shopping steps on its integration patent.
