Nippon Drops Electrical Steel Lawsuit Against Toyota, as Automaker Embraces e-Mobility
Embracing a future of e-mobility with many types of electric vehicles, Toyota will no longer have to worry about Nippon Steel's patent infringement
lawsuits involving electrical steel for Toyota's motors. President Koji Sato presented the company's new vision at Japan Mobility
Show 2023, formerly the Tokyo Motor Show.
Embracing a vision of finding your future in e-mobility, Toyota's
future will no longer be in court battling Nippon Steel in three
patent infringement cases over the giant automaker's use of
electrical steel for its motors. After two years of litigation, the
cases were closed about the same time that Toyota proclaimed
its " Find Your Future " theme at Japan Mobility Show 2023,
formerly the Tokyo Motor Show, envisioning the adoption of
multiple forms of electric vehicles.
The company announced on November 2 that Nippon Steel has
decided to drop its lawsuits over electrical steel sheet patents
against Toyota brought in 2021 and the cases have been
closed. Toyota had been the target of three patent infringement
lawsuits by Nippon Steel related to electrical steel sheets used
in EV motors and manufactured by Baoshan Iron & Steel Co.,
Ltd. (Baosteel) of China.
For the next two years, the court heard arguments over the
possibility of patent rights being infringed. But on November 2,
according to an announcement by Toyota, Nippon Steel began
waiving all claims related to the lawsuits. A waiver of claim is
a termination of the litigation initiated by the plaintiff and has
the same effect as a final judgment. This closes the lawsuits
between Nippon Steel and Toyota regarding electrical steel
sheets, declared Toyota.
Electrical steel, also known as silicon steel, is a specialty steel
used in the cores of electromagnetic devices such as motors,
generators and transformers because it reduces power loss.
It is an iron alloy which utilizes the ferromagnetic properties of
iron with silicon as the main additive element. Electrical steels
are the most-used (over 90% by volume) materials among all
soft magnetic materials.
Nippon Steel has been a major steel provider to Toyota over

many years. Other top players in the electrical steel market are
Thyssenkrupp, POSCO, JFE Steel, NLMK Group, Tata Steel,
China Baowu Steel, Aperam, ArcelorMittal, Baosteel, Cleveland-Cliffs,
Slovenian Steel and Voestalpine.
From the outset, Toyota argued that as a user of electrical steel
sheets it should not have been made a party to the litigation. " In
our dealings with various material manufacturers, our company
implements on each occasion a careful process of confirming
with them that there are no patent conflicts. Concerning the
electromagnetic steel sheets manufactured by Baoshan Iron &
Steel Co., Ltd. (Baosteel), as well, we confirmed that there was
no infringement of another company's patent before concluding
a contract. We also received a written statement from
Baosteel to that effect. Because Nippon Steel mentioned to us
its concerns, we confirmed again with Baosteel, which, in turn,
expressed its view to us that there was no patent infringement. "
