In late December, NorthStar Systems LLC expanded its first litigation campaign, begun in September 2020, with suits against H&M (2:20-cv-00407), Kohl’s (2:20-cv-00404), Lululemon (2:20-cv-00403), Target (2:20-cv-00405), and Walmart (2:20-cv-00406) in the Eastern District of Texas. The three patents-in-suit, received from Intellectual Ventures LLC (IV) in two December 2019 assignments, generally relate to a system for tracking an inventory of physical assets equipped with communication devices. The defendants are accused of infringement through the provision of RFID asset tracking systems deployed throughout their locations.
