Google, Yahoo countersue Xerox on search patents
Google Inc, its YouTube video service, and Yahoo Inc on Thursday filed counterclaims against Xerox Corp in a lawsuit accusing them of infringing the document management company’s patents on Internet searches.
In filings in Delaware federal court on Thursday, the defendants sought declarations that they did not infringe the two patents at issue, or variantly that the patents are invalid and thus cannot be enforced by Xerox.
