The US International Trade Commission (ITC) has opened investigation 337-TA-1526 after Vicor alleged that certain vertical power delivery systems, components and computing systems infringe its patent. Luxshare says the case is unlikely to materially affect its near-term business because the products involved remain in customer validation and have not entered mass production. That is the company’s assessment—not a decision on infringement or the case’s outcome.

What the investigation covers
Vicor filed its complaint on September 9, 2026, and the ITC instituted the investigation on October 9. The case concerns products imported into or sold in the United States in the categories named in the investigation: vertical power delivery systems, their components, and computing systems containing them.

The complaint identifies US Patent 10,903,734. Reporting describes the technology at issue as power-delivery products for computing and data-center applications.

23 The investigation’s product categories do not mean that every product in those categories—or every computer made by a respondent—has been found to infringe. The ITC has not yet made a decision on the merits.

The case names 20 respondents, including Luxshare Precision Industry and its subsidiary Dongguan Luxshare Technology, alongside companies involved in power components and computing systems.

45 The focus is on the specified power-delivery technology, not on Luxshare’s Apple-related manufacturing generally.

Why Luxshare expects limited near-term impact
Luxshare says the products relevant to the investigation are still undergoing customer verification and have not entered mass production. It therefore expects no material impact on current operations or near-term business results.

That statement describes Luxshare’s view of its current commercial exposure. It does not resolve whether the products infringe the patent, or rule out consequences if the ITC ultimately finds a violation. Depending on the products covered by any final remedy, a decision could affect their importation or certain US commercial activity. The available information does not quantify Luxshare’s potential financial exposure.

Luxshare has said it is responding to the case and working to protect shareholder interests.
27 The available reporting does not establish the details of its legal defenses, any proposed product changes, or specific customer agreements.
What Vicor is seeking
Vicor has asked the ITC for a limited exclusion order and cease-and-desist relief concerning the products it alleges infringe.
1 In general, an exclusion order can restrict imports of covered goods, while a cease-and-desist order can address specified commercial conduct involving those goods. Neither request amounts to a blanket ban on all products or business activity by every respondent; the scope would depend on the ITC’s findings and any order it issues.

What happens next
The ITC sets a target completion date within 45 days of instituting an investigation. That is a deadline for setting the case timetable, not a promise that the investigation will be completed in 45 days.
44
The case proceeds through an evidentiary process before an administrative law judge, who issues an initial determination. The commission may then review that determination and decide whether Section 337 was violated. Opening an investigation is not itself a finding of infringement or an order granting Vicor’s requested remedies.

If the commission issues remedial orders, they take effect when issued and become final after the 60-day review period unless the US Trade Representative disapproves them for policy reasons.

A separate Federal Register notice confirms that the ITC instituted another Vicor investigation on February 11, 2026.
43 The materials available here do not establish enough detail to assess how that proceeding’s patent claims or product scope relate to this case. The important distinction for 337-TA-1526 is that Luxshare’s expectation of limited near-term disruption is not a ruling on the merits: both the infringement allegations and the possibility of remedies remain unresolved.
