("Chip One"; head office: Yokohama-Shi, Kanagawa Prefecture, Japan; Representative Director: Masayuki Kojo) from infringing Nichia's patent (No. 4530094, or "patent No. 094") with regard to white LED products (product number: GT 3528 series) manufactured by EVERLIGHT ELECTRONICS Co., Ltd. (“Everlight”; head office: Tucheng Dist., New Taipei City, Taiwan; Chairman: Robert Yeh), the largest LED assembly manufacturer in Taiwan, and imported and sold by Chip One.
