Last year, Light Guide Innovations LLC filed separate complaints against first TCL (TCT Mobile and multiple subsidiaries) and then Hisense, both in the Eastern District of Texas, targeting the provision of LED strips used for television or other display backlighting. Each defendant has yet to answer (or otherwise respond). Now, Light Guide has sued Walmart (2:25-cv-00312) in the same district, asserting 16 patents from the same former Suzhou Lekin Semiconductor Co. Ltd. (d/b/a LEKIN) portfolio. The plaintiff targets the provision of VIZIO Quantum, Quantum Pro, 4k, Full HD, HD, M-Series, V-Series, and D-Series televisions. VIZIO is not named as a defendant.
