Nihon steel corp. raised a lawsuit against Posco (Korea) and Posco japan on the reason of patent infringement at Tokyo District Court. The reason of the lawsuit is that those companies clearly infringe the patent right on the grain-oriented magnetic steel sheet, which is owned by Nihon steel, and hence Nihon steel claims the compensation of damages of 1000 oku-yen (1 oku-yen = 100,000,000 yen) from those companies and demands for those companies to halt the manufacture and sales of any products manufactured based on the patent technology. Written referring to
Nikkan Kogyo shimbun.
