The company claims that its automatic query and information integration patents are being violated.
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.
Likewise, Xerox says that Google's YouTube infringes upon its integration patent.
Xerox is seeking treble damages because it claims the defending companies are aware of its patents and that their infringement is willful.
"We have been in dialog with Google and Yahoo for some time about licensing these patents, without reaching a resolution," a Xerox spokesperson said in an e-mailed statement. "We believe we have no option but to file suit to properly protect our intellectual property."
Google's senior litigation counsel Catherine Lacavera, said in an e-mail, "These claims are entirely without merit, and we'll vigorously defend ourselves against them."
Yahoo offered a similar statement. "Yahoo does not believe we infringe and plans to fight this case," a company spokesperson said via e-mail.
Google and Yahoo both support the Coalition for Patent Fairness, a group that has been lobbying for patent reform.
Supporters of patent reform argue that the patent system hasn't been amended since 1952 and have been trying for several years to rally support for legislation to change the patent system.
Google in the Enterprise SurveyThere's no doubt Google has made headway into businesses: Just 28 percent discourage or ban use of its productivity products, and 69 percent cite Google Apps' good or excellent mobility. But progress could still stall: 59 percent of nonusers distrust the security of Google's cloud. Its data privacy is an open question, and 37 percent worry about integration.
