On September 5, 2011, LED manufacturer Yiguang Electronics filed a request for invalidation of JP-A Chemical JP4530094 patent with the Japan Patent Office. Yiguang said that the company had received a notice of trial and approval from the Japan Patent Office a few days ago and found that the patent was invalid in Japan.
For this result, Yiguang pointed out that JP4530094 is a patent for Nichia White Light Technology. This time, the Japanese Patent Office has invalidated the judgment, which is of great significance to Yiguang. In the future, Yiguang will be expected to fully open the Japanese market.
It is understood that the Japanese Patent Office issued a notice on May 1, 2014, which confirmed that all the rights of the patent in Japan were invalid, and its invalid rights included the phosphor concentration distribution of the white LED.
