Google and Yahoo have countersued Xerox, which accused them of infringing its patents with their search technology.
According to Xerox’s filing, YouTube, Google Maps, AdWords, and Yahoo Shopping transgress on a patent covering technology to “automatically generate queries based on the content of web pages to retrieve related advertisements.”

The copying company is also suing for violation of a second patent that details a method of “integrating information from heterogeneous document and data sources”, which it claims is used in Google Maps and Video.
“We’ve been in dialogue with Google and Yahoo for some time without coming to a resolution,” Bill McKee, a spokesman for Xerox, told Bloomberg.
“We believe we have no option but to file suit to properly protect our intellectual property,” he added.
In filings in Delaware federal court, the defendants argued they did not infringe the two patents at issue, and that the patents are invalid and thus cannot be enforced by Xerox.
Xerox is seeking compensation for past infringements, and a ban on the defendants’ use of the technology.
