CHARTS: EV battery metals bill sets new low as lithium, nickel, cobalt price slump continues
The raw materials bill for the average EV is now down to $510 compared to a peak of more than $1,900 at the beginning of last year.
Seven Chinese rare earth companies are taking Japan’s Hitachi Metals to court in the United States, claiming the firm violated international patent law and established unfair market barriers against them.
The dispute revolves around neodymium-iron-boron magnets, which are widely used in in electric engineering, wind power, automotive and high tech industries. About half of the global consumption of rare earths is related to this magnetic alloy, whose intellectual property rights are mostly held by the Japanese firm.
According to China Business News, Hitachi Metals owns more than 600 neodymium iron boron magnet patents, but has authorized only eight Chinese companies to use them in a total of 149 patents.
Long-dragged battle
China produces 70,000 to 80,000 tons of the magnets annually, with half of the products used domestically. Only a quarter of the magnet manufacturers have patent licenses enabling the products to be sold offshore.
The battle over neodymium-iron-boron patents is nothing new. In 2012 the Tokyo-based filed a U.S. trade complaint against more than two dozen companies, seeking to block imports of competitors’ rare-earth magnets used in electronics, mostly coming from China.
Hitachi’s own material patent in the U.S. expired in July, opening the door for Chinese companies that had neodymium iron boron magnet patents different from those of the Japanese firm to demand being allowed to sell their products in the U.S.
