Nippon Steel Sues Baosteel & Toyota Over Electrical Steel Patent
In addition, Nippon Steel has filed a petition for a preliminary
injunction before Tokyo District Court prohibiting Toyota from
manufacturing and selling motor-driven vehicles using nonoriented
electrical steel sheets that infringe upon its patent.
Nippon Steel makes a several brands of non-oriented electrical
steel sheet, notably Hilitecore, Homecore and Hiexcore,
that it says offer superb magnetic properties with only minimal
deviation, made possible by its advanced production equipment
and manufacturing technology.
Nippon Steel Corporation has filed lawsuits against Baoshan
Iron & Steel Co., Ltd., a Chinese steelmaker, and Toyota Motor
Corporation asserting the two companies have infringed
upon its patent relating to non-oriented electrical steel sheets,
typically used in the iron cores of motors for vehicles.
Nippon announced the legal moves in October, also seeking
a preliminary injunction to prohibit Toyota from manufacturing
and selling vehicles that use the sheets. Filed in Tokyo District
Court, the lawsuits seek compensatory damages of about
$175 million each from the two defendants.
Electrical steel sheet is widely used as the fundamental
material to produce iron cores for electric generators in power
plants, electrical products, motor-driven vehicles, and vibration
motors in mobile phones. Non-oriented electrical steel
sheets have crystal orientation precisely controlled so as to
demonstrate isotropic in-plane magnetic properties. They are
widely used in the iron cores of rotating machines such as
motors.
As reported earlier in Magnetics Magazine, the company
raised its investment to nearly $1 billion at two of its plants
in Japan to increase production capacity and improve quality
of its electrical steel sheets. The moves were designed to
boost its capacity 40% by the first half of 2023 to meet rising
demand for transformers and electric vehicles.
