BOE HC Semitek Ltd. (Hengqin), a China-based LED manufacturer affiliated with display giant BOE Technology, has acquired 72 U.S. LED patents from Suzhou Lekin Semiconductor Co., Ltd., according to U.S. patent records dated February 20, 2025.
The deal marks BOE HC Semitek’s first known acquisition of U.S. patents from a third party.
Suzhou Lekin Semiconductor previously drew attention for purchasing 2,000 U.S. LED patents from Korea's LG Innotek in 2021. Since then, it has gradually divested portions of its portfolio to several entities.
According to public records, Lekin sold 9 U.S. LED patents to Focus Lightings Tech in 2022, 9 to Wangs Alliance Corporation in 2023, 27 to Light Guide Innovations in 2024, 164 to Fairlight Innovations in 2024, and 5 to SMR Intelligent, also in 2024.
Among the buyers, Light Guide Innovations is currently involved in multiple U.S. patent infringement lawsuits related to LED technology.
