Netlist, an Irvine, California-based memory technology company, filed a formal complaint with the US International Trade Commission against Samsung, Google, and Super Micro. The filing, dated September 30, 2025, alleges infringement of six patents tied to DDR5 memory modules and high-bandwidth memory (HBM) products.
Netlist isn’t just asking for money this time. The company wants US Customs and Border Protection to physically block the import of Samsung’s infringing DRAM modules, Google’s Tensor Processing Units, and Super Micro’s servers.
A patent portfolio with teeth
In April 2023, a jury awarded Netlist $303.15 million against Samsung for patent infringement. A second jury verdict in November 2024 tacked on another $118 million against Samsung for separate infringements. And in 2024, Micron was ordered to pay Netlist $445 million for patent violations.
The six patents at the center of the new ITC complaint include US Patent Nos. 12,737,366, 10,025,731, 10,268,608, 10,217,523, 9,824,035, and 12,308,087. These patents cover technologies used in DDR5 and HBM products.
