Ukrainian civilians filed multiple lawsuits in Texas accusing Intel, AMD, Texas Instruments and Mouser Electronics of enabling chip diversion into Russian weapons.
Plaintiffs argue U.S. firms demonstrated “willful ignorance” as sanctioned components surfaced in drones and missiles used in Ukraine.
Cases escalate political and regulatory scrutiny on semiconductor export controls amid growing geopolitical tensions.

A series of lawsuits filed in Texas has thrust some of the world’s largest chipmakers into the center of a high-stakes legal and geopolitical storm, accusing them of failing to prevent their semiconductors from appearing in Russian missiles and Iranian-made drones used against Ukrainian civilians. The filings target Intel, AMD, Texas Instruments and Mouser Electronics—a Berkshire Hathaway subsidiary—alleging corporate negligence and “intentional disregard” for export-control obligations. The cases reflect escalating pressure on U.S. technology companies as Washington tightens oversight of the global semiconductor supply chain, now viewed as a critical front in the conflict between Russia and the West.

Allegations of Diversion and Weak Export Controls

The lawsuits, filed on behalf of dozens of Ukrainian civilians, claim that the companies enabled or failed to prevent third-party resellers from diverting restricted components into Russia and Iran. While all named manufacturers publicly insist they halted business in Russia immediately after the invasion and enforce strict compliance policies, plaintiffs argue those measures were insufficient to stem illicit procurement routes.

According to the filings, components associated with Intel and AMD appeared in Iranian drones, while Texas Instruments chips were identified in Russian KH-101 cruise missiles and Iskander ballistic missiles involved in deadly strikes between 2023 and 2025. Lawyers cite the companies’ “willful ignorance,” alleging they knew that resellers were circumventing sanctions and continued to operate without adequate diversion-monitoring mechanisms.

The suits lean heavily on a Bloomberg investigative series showing that long-standing sanctions have repeatedly failed to prevent Western chips from reaching Russia’s defense industry, underscoring the challenge of policing a vast global distribution network.

Berkshire-Owned Mouser Faces Additional Scrutiny

Mouser Electronics, a key distributor acquired by Berkshire Hathaway in 2007, is accused of facilitating transfers to shell companies controlled by Russian proxies. Plaintiffs allege that Mouser’s domestic logistics operations constitute a “substantial component” of the misconduct contributing to civilian harm abroad. Mouser declined detailed comment, saying it would respond in court, while Berkshire Hathaway has not yet issued a public statement.

The cases were filed in Texas because the companies are headquartered or heavily operational in the state, and because active wartime conditions make litigation in Ukraine impractical.

Mounting Pressure From Washington and Investors

The lawsuits come as bipartisan pressure grows in Washington for stricter export-control enforcement. U.S. lawmakers, including Senator Richard Blumenthal, have previously criticized chipmakers for “objectively and consciously failing” to prevent Russia from exploiting American technology. Regulators may now face renewed calls to impose tighter oversight, expand reporting requirements and accelerate efforts to identify illicit transshipment hubs.

For investors, the suits highlight reputational and financial risks that could expand as geopolitical conflict increasingly intersects with the supply chains of Western technology firms. The semiconductor sector—already strained by export restrictions targeting China—may now face a parallel legal risk emerging from Russia-related diversion.

What to Watch Next

The Texas cases mark one of the most aggressive legal challenges yet to U.S. chipmakers over wartime technology diversion. If successful, they could set a precedent forcing global manufacturers to adopt more stringent monitoring of downstream distributors, potentially reshaping compliance costs and export-control obligations across the industry. With geopolitical tensions unlikely to ease, semiconductor firms may find themselves under sustained legal, political and regulatory pressure to demonstrate that their technology cannot be weaponized on distant battlefields.
