Rothschild Patent Imaging LLC (RPI) filed eight new suits this week, accusing Badoo Trading Limited (d/b/a Badoo Software Ltd.), Foursquare, Grindr, MeetMe, Photobucket, Skout, TangoMe, and Yahoo (Tumblr) of infringing an image processing patent (8,437,797). At issue are the defendants’ mobile applications that allow users to send photos to each other. To date, nearly thirty companies have been sued over the ‘797 patent via three separate litigation campaigns, all waged by various entities controlled by inventor Leigh M. Rothschild. Past defendants include Apple, Canon, HTC, LG Electronics, Microsoft, Panasonic, Samsung, and Sony, as well as Ricoh, which was sued earlier this month.
