China did not ignore the LFP patent. Hydro Quebec (LFP+C Consortium), the owners of the LFP patent had an agreement with China, that Chinese companies can make LFP batteries in China without a license fee as long as those batteries are sold to the local market.

Hydro Quebec didn’t want another long costly legal battle in China with only 10 years left on their LFP patent, so they made an agreement.
