The statement from Micron reads:
“The Fuzhou Intermediate People’s Court, Fujian Province, China today notified two Chinese subsidiaries of Micron that it has granted a preliminary injunction against those entities in patent infringement cases filed by United Microelectronics Corporation (UMC) and Fujian Jinhua Integrated Circuit Co. (Jinhua).”
“The preliminary injunction enjoins Micron’s Chinese subsidiaries from manufacturing, selling, or importing certain Crucial and Ballistix-branded DRAM modules and solid state drives in China. The affected products make up slightly more than 1% of Micron’s annualized revenues. Since the fourth fiscal quarter is underway, Micron anticipates that the negative impact to revenue this quarter relating to the injunction will be approximately 1%, and the company continues to expect revenue to be within the previously guided range of $8.0 to $8.4 billion. Micron will comply with the ruling while requesting the Fuzhou Court to reconsider or stay its decision.”
“In January 2018, UMC and Jinhua filed patent infringement suits in Fujian Province, China against Micron’s China subsidiaries. The lawsuits claim that certain Crucial and Ballistix-branded DRAM modules and solid state drives infringe UMC and Jinhua’s patent rights in China. Each of the asserted patents was originally granted to UMC, a Taiwan-based logic semiconductor foundry that lacks advanced DRAM and NAND flash technology.”
“The patents are not used in Micron’s DRAM and NAND technology or products, and UMC and Jinhua rely on distorted interpretations of the patents and improper evidence to support their false allegations that Micron infringes the patents.”
“Moreover, Micron has submitted compelling evidence to the Patent Review Board of China’s State Intellectual Property Office demonstrating that the patents are invalid because they are directed to technologies that were previously developed and patented in other countries by other technology companies.”
Micron is current,y under investigation by China’s anti-trust authorities for collusion in price-fixing on memories.
It relies on China for a substantisl proportion of its sales. According to DRAMeXchange, China was expected to buy 20% of Micron’s flash bit output this yesr and 26% of Micron’s DRAM bit output.
