Everlight Electronics Co (億光電子), the nation’s top LED chip packager, yesterday said the Japan Patent Office (JPO) had upheld its previous decision to invalidate all claims of Nichia Corp’s blue LED patent.
The JPO’s latest ruling came after Nichia appealed to the office on Nov. 12 last year for a correction trial, after the office rendered the Japanese firm’s patent JP2780691 invalid in the first trial.
It also ends a two-year fight between the two companies over the blue-light LED patent JP2780691.
Everlight’s shares closed up 0.11 percent at NT$47.2 yesterday on the news, outperforming the benchmark TAIEX, which fell 0.23 percent.
Everlight said in the statement that it “did not initiate patent litigations arbitrarily.”
However, the company will “counterattack without reservation when facing unscrupulous harassment from competitors, in order to protect the interests of Everlight’s customers,” it added.
The two companies still have other LED-related patent lawsuits ongoing in Taiwan, Japan and the US.
Separately, the Bureau of Standards, Metrology and Inspection (BSMI) yesterday said Taiwanese LED streetlight makers could send their products to certain institutions to see if they meet requirements to be labeled as energy-saving products.
The institutions include the government-funded Industrial Technology Research Institute’s Center for Measurement Standards, the Taiwan Electric Research and Testing Center, Metal Industries Research and Development Center and China Quality Certification Center’s office in Taiwan, the BSMI said.
