Netlist Seeks Import Ban on Essential Memory Chips Used by Major Tech Giants

Washington, Tuesday, 29 September 2026.
Netlist asked U.S. trade regulators to block Micron artificial intelligence chips, targeting Nvidia and Google in a patent dispute that threatens critical technology supply chains.

Netlist Initiates ITC Complaint

Patent licensing firm Netlist has filed a legal complaint with the U.S. International Trade Commission (ITC) seeking an import ban on certain memory chips manufactured by Micron Technology (MU) [1]. The legal action was initiated on 28 September 2026, targeting technologies used in high-performance computing and artificial intelligence infrastructure [2]. If granted, an import exclusion order could disrupt key supply chains within the domestic AI hardware ecosystem [1]. This filing represents a significant escalation in the intellectual property dispute surrounding high-bandwidth memory components [6].

Targets Include Major Tech Giants

The legal action extends beyond Micron to target major enterprise customers using the technology, including Nvidia (NVDA), Alphabet’s Google (GOOGL), and Broadcom (AVGO) [3]. Netlist is seeking exclusion and cease and desist orders against these named respondents regarding its high-bandwidth memory patent portfolio [2]. The complaint targets Micron DRAM, as well as graphics processors, servers, and other equipment from the listed companies that incorporate the components at issue [1]. Micron, Google, Nvidia, and Broadcom did not immediately comment on the filing [1].

Patent Specifics and Technology

Netlist alleges these technologies infringe two of its patents related to high-bandwidth memory, specifically U.S. Patent Nos. 12,308,087 and 12,646,537 [2]. The complaint focuses on HBM3E, HBM4, and HBM4E products used in AI computing [2]. Netlist says it is seeking to protect memory technologies developed over several decades and now widely used in AI infrastructure [1]. The company states this action reflects its continued commitment to protecting foundational technologies from unauthorized use [2].

Prior Legal Battles

This new action is part of a broader dispute between Netlist and Micron, following a 2024 federal court order in Marshall, Texas, requiring Micron to pay $445 million to Netlist for patent infringement [1]. In August 2026, Netlist had already filed with the ITC over Micron chips found in products from Super Micro Computer, Hewlett Packard Enterprise, and Lenovo [1]. The ITC voted to investigate those earlier DRAM products on 23 September 2026, instituted as Investigation 337-TA-1523 [2]. Earlier this month, Netlist lost its appeal in a separate patent case against Micron involving computer memory systems [3].

Market Implications

The inclusion of Nvidia, Broadcom, and Google alongside Micron reflects the supply-chain structure of the claim, since HBM is an input into the accelerators and systems those firms ship [6]. Historical patterns in comparable ITC memory and chip cases suggest respondents have tended to settle or license well before exclusion becomes a live risk [6]. Outright import bans on strategically important components have been rare in previous proceedings [6]. Netlist acknowledges that monetizing and defending its patent portfolio may not be successful due to the unpredictability and costs of litigation [2].

Outlook for Supply Chains

Netlist identifies various operational risks, including potential supply chain failures and changes in international trade and tariff policies [2]. The company filed its Annual Report on Form 10-K for the fiscal year ending December 27, 2025, with the U.S. Securities and Exchange Commission on 19 March 2026 [2]. Market observers note that the timeline of the investigation, rather than the filing itself, is the tradable signal for investors [6]. The commission’s decision on whether to institute the investigation and the target date for completion will be critical factors to watch [6].
