suraj.sun (1348507) writes "Xerox has filed a complaint against Google and Yahoo on Friday in U.S. District Court in Delaware (click for PDF), as operating products and services that infringe on two Xerox patents for organizing documents. The two patents, No. 6,778,979 and No. 6,236,994, were granted to Xerox in 2004 and 2001, respectively.
In its complaint, Xerox said various services from Google and Yahoo--including AdWords, Yahoo Search, and YouTube--fall under the scope of the patents, entitled "System for Automatically Generating Queries" and "Method and Apparatus for the Integration of Information and Knowledge." Xerox is seeking an injunction against Google and Yahoo as part of the case, which is a relatively common move in patent trials.
