On September 23, 2026, the US International Trade Commission (ITC) voted to initiate a 337 investigation (337-TA-1523) into certain dynamic random access memory (DRAM) devices, downstream products, and components. The probe follows a complaint filed on August 11, 2026, by California-based Netlist, Inc., alleging patent infringement by companies importing and selling such products in the US. The asserted patents include US Patent Nos. 10,025,731, 10,217,523, 12,373,366, and 12,675,407. Named as respondents are Micron Technology, Micron Semiconductor Products, Hewlett Packard Enterprise, Lenovo Group (Hong Kong), Lenovo (United States), and Super Micro Computer. Netlist is seeking a limited exclusion order and a cease-and-desist order. The ITC will set a target completion date within 45 days of initiation. Any remedial orders issued would become effective upon issuance and final after 60 days, unless vetoed by the US Trade Representative.
