Asian Tech Press (Nov 13) -- Chinese chipmaker Yangtze Memory Technologies Corp. (YMTC) has sued its US counterpart Micron Technology Inc. in the US over patent infringement.

Information from the U.S. District Court for the Northern District of California shows that YMTC has sued Micron and wholly-owned subsidiary Micron Consumer Products Group LLC on November 9 for infringing eight of its US patents.

YMTC said in the patent infringement complaint that the lawsuit is to "put an end to Micron's widespread and unauthorized use of YMTC's patented innovations."

Founded in 2016, YMTC is China's largest 3D NAND flash memory chips manufacturer, and has become a key player in the global 3D NAND market.

Micron has used YMTC's patented technologies to fend off competition from YMTC and to gain and protect market share, the Chinese chipmaker said in the lawsuit.

The lawsuit seeks to "address one facet of Micron's attempts to hinder competition and innovation via its attempts to force YMTC out of the 3D NAND flash memory market," YMTC noted.

YMTC accused Micron of infringing U.S. Patent Nos. "10,950,623," "11,501,822," "10,658,378," "10,937,806," "10,861,872," "11,468,957," "11,600,342" and "10,868,031".

In response, Micron said it would not comment on pending litigation.
