The patent with JP No 2927279 is one of NICHIA's patents related to a white-LED technology, especially to obtaining white color emission by combining a semiconductor device and a phosphor that is excited by the light emitted from the semiconductor device. NICHIA holds patents regarding this technology in many countries.

NICHIA believed that the white LEDs with model numbers 99-215UWC/TR8 and 67-21UWC/S400-A4/TR8 handled by E&E JAPAN infringe upon NICHIA's above mentioned white LED patent and, therefore, filed a petition for a preliminary injunction order with the Tokyo District Court.

In fact, NICHIA in 1999 had a patent dispute with EVERLIGHT JAPAN regarding NICHIA's patent with JP No. 2900928, claimed a preliminary injunction order to cease EVERLIGHT JAPAN from marketing the infringing products (model Nos. 333uwc, 383uwc, and 204uwc). This dispute was settled due to the undertaking EVERLIGHT JAPAN gave for no more infringement on NICHI's patent.

NICHIA CORPORATION plans to continue to take appropriate worldwide actions toward any possible infringing company so as to safeguard its patents and other intellectual property rights in the future.
