Groupon, LivingSocial, Discount Marketers, Sued Over Patent Groupon Inc. (GRPN) and LivingSocial Inc. were sued by a patent owner claiming the discount online marketers are infringing protected technology for mobile telephone advertising. XcellaSave Inc., based in Middle Village, New York, asks for a jury trial and unspecified damages from Chicago-based Groupon and LivingSocial of Washington, according to two lawsuits filed Aug. 29 in federal court in Delaware. It’s accusing the companies of infringing patent 8,254,894, which was issued Aug. 28. The infringing companies continue “to create and disseminate promotional and marketing materials” and technical information in applications including the iPhone, Android, BlackBerry and Windows-based mobile phones, without permission, XcellaSave alleges in court papers. Groupon spokeswoman Julie Mossler declined to comment on the lawsuit. LivingSocial spokeswoman Maire Griffin didn’t immediately return an e-mail message seeking comment on the lawsuit. The cases are XcellaSave v. Groupon, 12-cv-1085 and XcellaSave v. LivingSocial, 12-cv-1086, U.S. District Court, District of Delaware (Wilmington).
