The patent for use of NiMH batteries in cars expired in 2018, so there is no need for any legal maneuverings.

People just don't make large format NiMH because LiIon cells have better performance/price.


"But Chevron Corp. held the patent US6969567 for the NiMH multi-cell battery pack for cars[37] until its expiration on August 23, 2018"
