Chinese Chipmaker Sues Micron for Alleged Patent Infringements

According to the lawsuit, Micron turned to YMTC's patented technology to fend off competition from YMTC and to gain and protect market share, saying Micron was not paying its fair share to use the patented inventions. Micron declined to comment.

Micron makes DRAM chips and NAND flash memory chips. YMTC is one of its smaller rivals and was barred last year by the U.S. from buying particular American components. The U.S. has increased restrictions on exporting chipmaking technology to China.

Reuters says Micron was embroiled in a dispute in 2018 involving Chinese state-backed chipmaker Fujian Jinhua, accused of trade secret theft. Later that year, its main products were subject to a temporary sales ban in China.

China was once Micron's biggest market, generating half its $20 billion revenue in fiscal 2017. That share shrank to 16% in 2022, a year in which it closed DRAM operations in Shanghai.
