Vicor seeks import and sales restrictions. Luxshare says its affected products remain in customer testing and expects no material business impact.
Listen to this story
The U.S. International Trade Commission opened a Section 337 investigation on October 9, 2026, after Vicor alleged that imported vertical power delivery systems and computers containing them infringe its patents. The 20 respondents include major AI-server suppliers Foxconn, Luxshare and Quanta, putting components as well as complete systems under scrutiny. Vicor is seeking import-exclusion and cease-and-desist orders, but the commission has made no infringement finding; the case must proceed through an evidentiary hearing and review before any remedy is decided.
The products at issue deliver power to high-end chips from directly beneath them, and the investigation covers systems, components and computers containing them.
Luxshare said its products are still in customer testing, are not in mass production and are not expected to materially affect its business.
The commission will set a target completion date within 45 days; an administrative law judge will first issue a determination subject to commission review.
Vicor is seeking to block disputed AI-server power products from the United States, while Luxshare expects no material business impact. The U.S. International Trade Commission voted on October 9, 2026, to open a patent investigation naming Foxconn, Luxshare and Quanta among its respondents. The case covers power components and computers containing them.
The case follows a complaint filed on Vicor’s behalf on September 9 and supplemented the next day. Vicor alleges that imports and sales of the products infringe claims of its patent, violating Section 337 of the Tariff Act of 1930.
The technology at issue is called vertical power delivery: systems that feed electricity to high-end chips from directly beneath them. The investigation covers those systems, their components and computers containing them.
Several corporate families appear through multiple entities. Foxconn appears as Hon Hai Precision Industry, Foxconn Industrial Internet and FII USA. Quanta appears through Quanta Computer, Quanta Cloud Technology and their U.S. entities.
The official list includes multiple entities from several corporate families.
Luxshare said in an October 10 filing that it does not expect the investigation to materially affect its production, operations or results, according to The Next Web, citing Bloomberg. The company said its products are still being tested by customers and are not in mass production.
Vicor has requested a limited exclusion order and cease-and-desist orders to block imports of the disputed products and stop their sale. The commission has not decided whether infringement occurred.
The commission’s chief administrative law judge will assign the case to a judge who will schedule and hold an evidentiary hearing. That judge will issue an initial determination on whether Section 337 was violated, subject to commission review.
Within 45 days of opening the investigation, the commission will set a target date for completing it. It says it will reach a final determination at the earliest practicable time.
If the commission issues remedial orders, they take effect when issued and become final 60 days later unless the U.S. Trade Representative disapproves them for policy reasons.
