TOKYO (AP) — Nippon Steel Corp. is suing Toyota Motor Corp. over a patent for a technology used in electric motors in a rare case of legal wrangling between Japan’s top steelmaker and top automaker over intellectual property.

Tokyo-based Nippon Steel filed the lawsuit Thursday in Tokyo District Court, demanding compensation for damages totaling 20 billion yen ($177 million). Also named in the lawsuit is Baoshan Iron & Steel Co., or Baosteel, a Chinese steelmaker that produces and supplies the steel that allegedly violates the patent.
