Nearly two years ago, Optima Direct, LLC acquired eight US patents from AmTRAN Technology, five of them originating with Sarnoff (now STI International) and three, with Industrial Technology Research Institute (ITRI). Optima Direct has filed its first litigation over the acquired assets, asserting one of the former ITRI patents in separate cases against INPAQ (5:21-cv-02817), Sunlord (5:21-cv-02822), and Yageo (4:21-cv-02823) in the Northern District of California; Yageo subsidiary Pulse Electronics (3:21-cv-00768) in a separate suit in the Southern District of California; and Panasonic (1:21-cv-00177) and TI (1:21-cv-00176) in the Eastern District of Texas. The litigation, which is not Optima Direct’s first, targets the provision of certain chip antenna units, either alone or within larger “Wi-Fi modules”.
