Nichia wins Texas patent infringement lawsuit against Everlight

Japan-based LED maker Nichia Corp says that the US District Court for the Eastern District of Texas has judged that Taiwanese LED packaging firm Everlight Electronics Co Ltd and its US subsidiary Everlight Americas Inc have infringed three Nichia patents. Nichia filed with the court for patent infringement in September 2013.

The court judged that Everlight has infringed Nichia's Patent No. 8,530,250, and rejected Everlight's assertion that the patent is invalid. The patent covers a process for manufacturing LEDs that Nichia developed in 2008, as well as LED products manufactured using the process. The Nichia products covered by the patent include Nichia's 757 and 157 series of products. The Everlight products found to infringe the patent include the XI3030, XI3535, 62-217D, 62-257D and 45-21S series of LED products.

The court also found that Everlight has infringed Nichia's US Patents No. 7,432,589 and No. 7,462,870. It also denied Everlight's contentions that these patents are invalid.

In response, Everlight notes that the court issued no damages against it and denied Nichia's request of injunctive relief (to prevent Everlight from selling LED products in the USA). Everlight aims to appeal.

Everlight also notes that in 2012 it filed a declaratory judgment action against Nichia's US Patent Nos. 5,998,925 and 7,531,960 (regarding YAG phosphor used in LEDs and the phosphor concentration) for invalidity and non-infringement. On 19 January, the District Court for the Eastern District of Michigan denied Nichia's motion for judgment and confirmed the jury verdict of invalidity on all Nichia's asserted claims.
