One recently formed NPE affiliated with Empire IP LLC has asserted a familiar patent in a new litigation campaign, while another has expanded an existing campaign, both in Texas. Listou Search Technologies LLC filed separate complaints against clothing retailers Men’s Wearhouse (5:16-cv-00144) and Stanley Korshak (5:16-cv-00145), asserting a single patent (6,216,139) generally related to the display of dialog boxes in a computer system. As in the prior campaign, litigated by the inventor in Delaware, the accused products are the defendants’ websites. Meanwhile, Theft Prevention Innovations LLC has added cases against AeroScout and Stanley Black & Decker (2:16-cv-01060), Elpas and Tyco (2:16-cv-01057), and RF Code (2:16-cv-01059). Two patents (7,671,741; 9,165,446) from a three-patent family generally related to anti-theft systems are asserted in the campaign, which targets the defendants’ asset tags and tracking systems.
Theft Prevention Innovations LLC (TPI), a newly formed affiliate of Empire IP LLC, has filed three complaints against four location tracking companies, AwarePoint (2:16-cv-00469), AiRISTA and Ekahau (2:16-cv-00470), and Sonitor Technologies (2:16-cv-00472). The May 3 complaints each assert two patents (7,671,741; 9,165,446) from a family of three that generally relate to a security system based on attachable security tags, each of which has an alarm that sounds when the tag is removed or moved into a predetermined “warning zone”. Defendants are accused of infringement through the sale of real-time location systems (RTLS) that use RFID or ultrasonic security tags.
