This study used USPC, ECLA, WIPS and Delphoin database to analyze Nichia patents. Results showed Nichia Corporation had 4561 patents and most of patents applied predominately in Japan.. Family A is based on nitride crystal to produce mono-crystal and bulk crystal through methods of pressure, temperature and ammonia solution. Family C is based on nitride structure, through arrangement, phosphor concentration, material and wavelength to control hybrid light. Through citation analysis, it showed Nichia had high independent R & D capability and extension of research results. Through priority analysis, we found Nichia focused mainly on Japan. But patent strategy is very peculiar in in Poland, Nichia started to cooperate with somebody, so do competitors.
