Sep 8, 2010
Nichia Corporation announced that it had filed four provisional injunction actions in Tokyo District Court to enjoin Tsannkuen Japan (Sankun Nihon Denki Kabushiki Kaisha) from infringing Nichia's patent.
Nichia believes white LEDs used in certain LED light bulb products of Tsannkuen Japan, sold by G.K. Seiyu and K.K. Yamada Denki, infringe Nichia's white LED patents (No. 3724498, No. 3995011, No. 4109297, No. 4530094).
The patent is one of Nichia's patents concerning the technology of combining phosphor with blue LED, and is employed in many white LED products that combine phosphor with blue LED.
