It has been named as a defendant in one U.S. patent case and has not been tracked as a plaintiff. This suit was filed in the U.S. District Court for the Eastern District of Texas, a common venue for patent disputes.

The single tracked case is Light Guide Innovations LLC v. Hisense Company Ltd. et al., filed in early 2025. The plaintiff, Light Guide Innovations, has been identified by industry sources as a non-practicing entity (NPE). The lawsuit involves patents related to LED backlight technology used in modern televisions. The patents were originally developed by LG Innotek and later acquired by Light Guide Innovations, which has also sued other major television manufacturers, including Samsung and TCL, using the same portfolio.
