Tokyo-based Nippon Steel said it is still suing Baoshan Iron & Steel Co., or Baosteel, a Chinese steelmaker that produces and supplies the steel that it alleges violates the patent.

Nippon Steel will continue its lawsuits against Baoshan, and will "firmly protect its intellectual property rights as the fruits of its technological development," it added.
