Seoul Semiconductor of South Korea issued a statement in a white LED lawsuit with Nichia Chemical Industry that the company has not infringed on the European patent EP541373 owned by Nichia Chemical Industry. On September 16, 2008, Nichia Chemical Industry filed a lawsuit in the UK. It refers to Seoul Semiconductor's white LED Acriche infringing the patent.
Seoul Semiconductor said: Acriche accepted the technical licenses of Gertrude Neumark Rothschild and the University of California, Santa Barbara, and has no relationship with the patents of Nichia Chemical Industry. Furthermore, regarding the patent (EP541373) of the Nichia Chemical Industry that heat-treats the p-type GaN-based semiconductor film at a high temperature of 400 ° C or higher, Seoul Semiconductor believes that because of similar advanced technology, the Japanese patent has invalid reasons (Seoul semiconductor).
