Nichia Corporation today announced that the United States Court of Appeals for the Federal Circuit has affirmed a district court decision holding that Everlight Electronics Co., Ltd. and Everlight Americas, Inc. have infringed three Nichia patents.

The court of appeals upheld the district court’s judgment that Everlight has infringed Nichia’s Patent No. 8,530,250 (the “’250 Patent”), and affirmed the district court’s rejection of Everlight’s assertion that the ‘250 Patent is invalid. The ‘250 Patent covers an innovative process for manufacturing LEDs that Nichia developed in 2008, as well as LED products manufactured according to that process.

The Nichia products covered by the ‘250 Patent include Nichia’s 757 and 157 series of products, which are among the most popular LED products on the market today. The Everlight products found to infringe the ‘250 Patent include Everlight’s XI3030, XI3535, 62-217D, 62-257D, and 45-21S series of LED products.

The court of appeals also upheld the district court’s judgment that Everlight has infringed Nichia’s U.S. Patents No. 7,432,589 and No. 7,462,870, and affirmed the district court’s rejection of Everlight’s challenge to the validity of those patents.

Nichia filed its infringement claims against Everlight in 2013. The district court entered its judgment in 2016. The court of appeals’ decision affirming the district court’s judgment, Nichia Corp. v. Everlight Americas, Inc. et al., Nos. 2016-1585, -1618, was issued on April 28, 2017.
