Japan’s Nichia Corp yesterday said it won a patent fight against Taiwan’s Everlight Electronics Co (億光電子) in a recent patent suit in China.
Based on a written judgement of China’s Beijing No. 1 Intermediate People’s Court on Oct. 22, Nichia said the court’s ruling upheld the validity of two of its patents, collectively called “Nichia’s YAG patents,” registered in China.
The court’s judgement came after Everlight, the nation’s largest LED chip packager, appealed to the court to challenge a previous decision by the Patent Reexamination Board, which is supervised by the Chinese government’s State Intellectual Property Office, Nichia said.
The court dismissed all of Everlight’s requests and affirmed the decision of the Patent Reexamination Board was valid, the Japanese firm said.
Everlight yesterday said the ruling will not impact on its business.
As of September, Everlight and Nichia had filed a total of 28 lawsuits against each other in countries including China, Japan, Germany and Taiwan, Nichia said.
Among all, Nichia had received 19 favorable rulings in Japan and China and is still waiting for judgement from a Japanese court amid its appeal, the company said.
Nichia yesterday did not update the media on latest developments in another eight legal cases involving Everlight.
