On May 17, 2023, Nichia Corporation (“Nichia”) and CoreStaff Co., Ltd. (“CoreStaff”) settled the patent infringement lawsuit pending before the Tokyo District Court (Case No. Reiwa 5 (Wa) No. 70062) based on Nichia’s Japanese Patent No. 4974310, relating to KSF (PFS) phosphors, in which Nichia had sought an injunction against patent infringement and damages.

Out of respect for Nichia's intellectual property rights and other considerations, CoreStaff, promptly and without proceeding with the lawsuit, discontinued handling the products subject to the lawsuit, specifically the “F90” family of LEDs made by the U.S.-based LED manufacturer Bridgelux, Inc, which CoreStaff had been selling.

While Nichia welcomes fair competition and believes it often leads to improved innovation, which ultimately serves the greater good of the industry and its consumers, Nichia will not shrink from steadfastly protecting its intellectual property, including its KSF phosphor-LED patent portfolio. As a leading innovator, known for producing high quality LEDs and ever improving the nature of light and optical mechanisms, Nichia's intellectual property serves as a springboard for its own future innovation, and therefore must be defended.
