Judge: Richard G. Andrews
Court: Delaware District Court
Case Summary:
Walker Digital, a Stamford based
company creating applications and business solutions filed a suit against
Google, Yahoo! and Microsoft for unauthorized use of its intellectual
properties. The patent involved in the suit was US7801802, entitled ‘Method,
system and computer program product for facilitating an auction behavior and
automatic bidding in an auction’ issued on Sep 21, 2010 and expiring[i]
by Mar 10, 2020. The patent is assigned to Walker
Digital and Jay Walker (founder), also one of the
named inventors of the patent in suit.
Walker
Digital alleges that the defendants have used the patented technology for
advertising and cites each company’s brand of targeted ad services including Ad
words ad placement auction, Search advertising service and Advertising ad center
as infringing technologies. Complaint sought judgment of infringement, money
damages, permanent enjoinment from using their patents and attorneys’ fees and
other relief, the Court may deem just and proper.
In July 2012, stipulation of
dismissal as to Yahoo! was filed by the parties and the Court ordered granting
the dismissal. In Jul 2013, Google was terminated from the case and two days later,
a final verdict was rendered (as a result of stipulation of non-infringement
filed) in favor of Microsoft, ordering that the accused products do not
infringe the claims asserted in the ‘802 patent. Counterclaims against Walker
Digital were dismissed without prejudice. Further details of the verdict are not disclosed.
