ITC Launches Investigation into Samsung Memory: High-Stakes Escalation in the Netlist Dispute

The U.S. International Trade Commission (ITC) has formally instituted a Section 337 investigation into Samsung Electronics' memory products. This move follows a complaint by Netlist, Inc., alleging infringement of patents related to high-performance memory modules. The investigation carries the risk of a Limited Exclusion Order (LEO), which could effectively bar the importation of Samsung’s flagship memory technologies, including High Bandwidth Memory (HBM) and DDR5, into the United States.
On January 2, 2026, the ITC announced its decision to investigate Samsung Electronics Co., Ltd., and its subsidiaries (along with co-respondents Google and Supermicro) regarding the importation and sale of certain semiconductor devices, specifically memory modules and components thereof. The complaint, filed by Irvine-based Netlist, Inc., asserts that Samsung's products infringe upon several key patents essential for high-speed, high-density memory operations. These patents are central to the architecture of server-side memory and the burgeoning HBM market, which is critical for AI infrastructure.
The relationship between Samsung and Netlist transitioned from collaboration to litigation in 2015. Originally, the two companies entered into a joint development and licensing agreement. However, disputes over the scope of the license and payment obligations led to a total breakdown. In recent years, Netlist has successfully secured significant jury verdicts in the Eastern District of Texas, including a $303 million award in 2023 and a subsequent $445 million verdict in 2024 related to different patent portfolios.
"The ITC is often used as a 'nuclear option' by patent owners because of its speed and its ability to block market access entirely, rather than just seeking monetary damages."
Samsung’s legal strategy has focused on challenging the validity of Netlist's patents through Inter Partes Review (IPR) at the Patent Trial and Appeal Board (PTAB). While some claims have been invalidated, several key patents remain enforceable, giving Netlist the leverage to pursue an exclusion order at the ITC.
For IP counsel, the Samsung-Netlist saga is a masterclass in parallel litigation. Managing simultaneous proceedings in District Courts, the ITC, and the PTAB requires meticulous coordination. A win in one venue can be negated by a loss in another. Practitioners must ensure that arguments made during PTAB validity challenges do not inadvertently weaken infringement positions at the ITC.
Unlike District Courts, which under the eBay v. MercExchange precedent rarely grant permanent injunctions against large manufacturers, the ITC operates under a different mandate. If infringement and the existence of a 'Domestic Industry' are proven, an exclusion order is the default remedy. For legal operations teams, this necessitates a contingency plan for supply chain diversification if a key component is suddenly barred from the U.S. market.
With Samsung competing fiercely with SK Hynix and Micron for dominance in the HBM market (essential for NVIDIA’s AI GPUs), an ITC exclusion order would be catastrophic. It would hit Samsung’s revenue and could reshape competition across the AI hardware industry.
The ITC investigation typically takes 12 to 15 months to reach a final determination. During this period, the pressure on Samsung to reach a global settlement will escalate. Key milestones to watch include the Administrative Law Judge's (ALJ) Initial Determination and any potential intervention by the Presidential administration on public interest grounds. Given the critical nature of memory chips to the U.S. technology sector, the 'public interest' argument will likely be Samsung's primary defense if infringement is found.
