Yangtze Memory Technologies Co. (YMTC) said on July 29 that online claims alleging the U.S. Patent and Trademark Office ruled all 19 claims of its core 3D NAND patent invalid on July 28 were "seriously misleading." The company also rejected another circulating claim that "all related YMTC concept stocks plunged," calling it a malicious fabrication built on the same misleading information and saying it was seriously inconsistent with the facts. In the same statement, YMTC said that since November 2023 it has filed patent infringement lawsuits against Micron Technology in the United States involving 27 patents and 295 patent claims. Those cases remain under review. YMTC added that it would not comment on ongoing litigation and said relevant case developments can be checked through public channels.
