Nichia has held a press conference in Taiwan to explain a patent dispute

Since 2002, Nichia has been involved in more than 50 global patent lawsuits, including against TG, Cree, Rohm and Osram, said Akutagawa. In most cases, the lawsuits ended respectably, in which both sides reached a settlement and exchanged patent rights. However, in Nichia’s case against LED high bay lighting, the Taiwanese manufacturer spread biased information over the past year, resulting in the Japanese manufacturer's skepticism of Everlight’s trustworthiness and patent development. Akutagawa frankly remarked there were no signs of conciliating with Everlight yet.

According to data from Nichia, there are currently eight patent lawsuits between the two companies. Out of these, Nichia accused Everlight over patent infringements in six cases, while the remaining two were filed by Everlight against Nichia.In the patent infringement case filed jointly by Everlight and U.S. fiber optic manufacturer Emcore against Nichia’s on April 9, 2012, the patent used by Everlight belonged to Emcore, according to Akutagawa.


This is the second time that Nichia has held a press conference in Taiwan to explain a patent dispute.Nichia’s attitude has become more hawkish compared to its last press conference back in June 2012 to explain Japan’s Patent Office’s ruling that invalidated the company's blue LED patents. Akutagawa pointed out, the main reason of organizing another press conference, was impact from information released by Everlight over the past year has mislead clients to believing the company patents were worthless. Nichia announced it will launch a full scale war against Everlight products that have infringed patent rights.
