With the lawsuits filed in 2021, Nippon Steel sought compensatory damages from Toyota, Baoshan, Mitsui & Co and Mitsui & Co. Steel, alleging their infringement of its patents relating to non-oriented electrical steel sheets.

The Japanese steelmaker has terminated the lawsuits against Toyota and Mitsui by waiving claims against them, it said in a statement.

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.
