Study Finds US and Japan Hold Core Patents Despite China’s Rare Earth Supply Dominance
A recent study highlights that China dominates global rare earth mining and processing, accounting for about 70% of mining and nearly 90% of processing capacity. However, the United States and Japan hold most core patents for advanced rare earth functional material technologies, including permanent magnets, catalysts, and luminescent materials. This indicates China’s upstream supply advantage has not extended to leadership in key downstream technologies, prompting calls for enhanced innovation and collaboration amid strategic competition.
