Supronics LLC has filed a Western District of Texas complaint against Home Depot (7:24-cv-00331) over three LED lighting patents that it received, in a group of six, from Sinotechnix LLC in September 2024. This past July, Sinotechnix filed suit against Samsung in the Eastern District of Texas over six patents from among 18 that it has received from Seoul Semiconductor (or a subsidiary), between May and July of this year.

Sinotechnix LLC has filed what appears to be its first litigation, accusing Samsung (2:24-cv-00544) of infringing six patents from a portfolio received from Seoul Semiconductor back in May 2022. The patents are broadly directed to various aspects of lighting technologies—including “irradiation-redistribution lenses”, LED devices, LED fabrication, LED packages, and more—with infringement allegations in the new Eastern District of Texas complaint targeting Samsung over the provision of monitors and TVs that incorporate screen lighting technologies such as certain diffusion plates, lead frames, and lenses.
