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.
