ITC Launches Probe into Micron, Supermicro, and HPE Over Netlist DDR5 Memory Patent Allegations

The U.S. International Trade Commission (ITC) has opened an investigation into allegations that memory products manufactured by Micron Technology Inc. (Nasdaq: MU), Super Micro Computer Inc. (Nasdaq: SMCI), and Hewlett Packard Enterprise Co. (NYSE: HPE) infringe four patents held by Netlist Inc. (Nasdaq: NLST). The patents in question cover DDR5 registered dual in-line memory modules (RDIMMs) and multiplexer registered DIMMs (MRDIMMs), technologies widely used in data centers and high-performance computing environments.

The ITC’s probe follows a formal complaint filed by Netlist in August, seeking exclusion and cease-and-desist orders that could potentially restrict the importation of infringing products into the United States. Netlist’s Chief Executive Officer, C.K. Hong, emphasized the company’s commitment to enforcing its intellectual property rights, stating, “The Samsung agreement established an important industry benchmark for the value of our IP.”

This reference pertains to a landmark settlement reached in August between Netlist and Samsung Electronics Co., which resolved a protracted global patent dispute. Under the terms, Samsung gained access to Netlist’s patent portfolio, agreed to supply Netlist with DRAM and NAND products, and purchased 10 million shares of Netlist stock. The settlement followed two jury verdicts in Texas awarding Netlist a combined $421 million in damages during 2023 and 2024.

Despite the Samsung settlement, Netlist’s current ITC case against Micron involves a distinct set of patents and remains unresolved. Netlist’s shares declined approximately 2% in morning trading amid broader market weakness but saw retail investor sentiment improve from neutral to bullish on social media platform Stocktwits.

Among the targeted companies, Supermicro’s stock experienced the steepest decline, falling 3.4% amid overall market softness, while Micron’s shares dropped over 1.7%. Hewlett Packard Enterprise’s stock traded relatively flat. Retail sentiment on Stocktwits shifted to bearish for Supermicro and HPE, whereas Micron maintained a bullish outlook.

Micron has previously achieved significant legal victories against Netlist. Earlier this month, the U.S. Court of Appeals for the Federal Circuit upheld decisions by the Patent Trial and Appeal Board invalidating five Netlist patents challenged by Micron. These rulings underscore the ongoing contest over patent validity alongside infringement claims.

It is important to note that the ITC’s initiation of an investigation does not equate to a finding of infringement. Netlist bears the burden of proving its claims, while Micron and the other respondents retain the right to contest both infringement and the validity of the asserted patents.

In parallel, Micron is engaged in a separate patent dispute with Yangtze Memory Technologies Co. Ltd. (YMTC) concerning NAND flash memory technology. A German court recently issued injunctions related to two German utility models, restricting sales of certain products within Germany. Micron has appealed these rulings and disputes the findings. This litigation contrasts with Netlist’s focus on server memory technologies, including DDR5 and high-bandwidth memory (HBM).

Micron’s stock has demonstrated robust performance, gaining over 250% year-to-date and more than 530% over the past 12 months, reflecting strong investor confidence despite ongoing legal challenges.

The unfolding ITC investigation highlights the complex and competitive nature of intellectual property enforcement in the semiconductor memory sector, where companies vigorously defend their innovations amid rapid technological advancement and substantial market stakes.
