TOKYO, Oct 14 (Reuters) – Japan’s biggest steelmaker Nippon Steel Corp (5401.T) said on Thursday it had filed patent infringement lawsuits against Toyota Motor Corp (7203.T) and China’s Baoshan Iron & Steel Co Ltd (Baosteel) (600019.SS) with a Tokyo district court.
Nippon Steel is seeking 20 billion yen ($176 million) in damages from each company, alleging the two firms have infringed on its patents on non-oriented magnetic steel sheets that are used in electric vehicles, it said in a statement.
Toyota said in a statement to Reuters the suit was “very regrettable” and that it had found no patent infringement issues before it signed a supply deal with the steelmaker.
Baosteel said it did not agree with Nippon’s claims and it would “firmly” defend its rights and interests.
“The electrical steel sheets are indispensable materials for automobile electrification and are one of our key products aimed at helping decarbonisation for cars, electrical products and power plants” a Nippon Steel spokesperson said.
The world’s fifth biggest steelmaker by output has decided to take legal action as it could not reach a resolution through discussions with both companies, it said.
This is the first time Nippon Steel has filed a patent infringement lawsuit against Toyota, the spokesperson added.
