TOKYO -- Nippon Steel is seeking a court injunction to stop Toyota Motor from producing electric vehicles, in a patent infringement suit against the carmaker and a Chinese steelmaker.

The Japanese company said on Thursday that it has filed a lawsuit against Toyota and Baoshan Iron & Steel, a subsidiary of China's state-run China Baowu Steel Group. It accuses the two companies of infringing Nippon Steel patents that cover nonoriented electrical steel sheet, which is used in electric vehicle motors.
