XEROX SUES YAHOO & GOOGLE OVER
SEARCH-ENGINE PATENTS
Feb. 2010 —
Google Inc. and Yahoo! Inc., owners of the two biggest U.S. search
engines, were sued by Xerox Corp. over patent-infringement claims
related to search queries and data integration.The suit, filed Feb. 19
in federal court in Wilmington, Delaware, seeks cash compensation and an
order that would prevent Yahoo, Google and Google’s YouTube from
further using the patented Xerox technology without permission.The
inventions come from Xerox research into managing documents on the Web,
said Bill McKee, a spokesman for the Norwalk, Connecticut-based
company.“We’ve been in dialogue with Google and Yahoo for some time
without coming to a resolution,” McKee said in a telephone interview.
“We believe we have no option but to file suit to properly protect our
intellectual property.”One patent, issued in 2004, is for a way to
automatically generate a query based on keyword searches. Xerox claims
that Google’s AdSense and AdWords software, and Yahoo’s Search
Marketing, Publishing Network and Y!Q Contextual Search software are
infringing that patent.The second patent, issued in 2001, is for a way
of updating pages based on user reviews. Google Maps, Google Video, the
YouTube service and Yahoo Shopping all use that patented technique,
Xerox contends.‘Without Merit’
“We believe these
claims are without merit and we will defend against them vigorously,”
said Catherine Lacavera, Mountain View, California-based Google’s senior
litigation counsel.Officials with Sunnyvale, California-based
Yahoo didn’t immediately return messages seeking comment.Google had 65.4
percent of the U.S. search market in January, down from 65.7 percent in
December, according to ComScore Inc. in Reston, Virginia. Microsoft’s
market share rose to 11.3 percent in January from 10.7 percent the
previous month, while Yahoo dropped to 17 percent from 17.3 percent,
ComScore said.The case is Xerox Corp. v. Google Inc., 10cv136, U.S.
District Court for the District of Delaware (Wilmington).
