4 Luxshare expects little near-term business disruption, but that is the company’s assessment—not a determination that it will prevail or that future products face no risk.

Scope and patent connection
- Complaint and respondents: Vicor’s September 9, 2026 complaint led to the October 9 investigation covering 20 respondents, including Luxshare Precision Industry, Dongguan Luxshare Technology and companies across the power-component and computing-system supply chain.

19
- Technology: The allegations concern US Patent 10,903,734 and vertical power delivery technology used in data-center power applications, including processor power modules and integrated power-supply solutions.

- Important limit: The product-category description does not establish that every vertical power delivery product—or every computing system made by a respondent—infringes. Insufficient evidence is available here to identify the precise asserted patent claims, map their individual limitations to accused products, or assess validity and infringement.
- Apple connection: Luxshare’s identity as an Apple supplier should not be confused with the subject of this case: the available reporting describes data-center power technology, not a general investigation into its Apple-related manufacturing.

Business impact and Luxshare’s response
- Near-term exposure: Luxshare’s late-Saturday filing said the affected products remain under customer verification and have not entered mass production, explaining its expectation of no material effect on current operations or near-term results.
- Interpretation: That rationale addresses current commercial exposure, not the legal merits. Potential future risks include delayed qualification or launch, redesign or licensing costs, and restrictions on US market access if covered products are ultimately found to infringe.
- Response preparations: Reporting on the disclosure describes Luxshare preparing a coordinated technical, legal and business response and communicating with customers and supply-chain partners to safeguard its interests and shareholders.
22 Insufficient evidence is available to specify its defenses, proposed design changes, customer agreements or quantified financial exposure.
Remedies and earlier disputes
- Requested relief: Vicor seeks limited exclusion and cease-and-desist orders concerning allegedly infringing products.
28 A limited exclusion order would restrict covered imports associated with the respondents; cease-and-desist relief could restrict specified US commercial activities involving covered goods, rather than impose a blanket worldwide ban on those companies’ businesses.
- February proceeding: An official Federal Register notice confirms a separate Vicor investigation instituted on February 11, 2026.
7 The evidence supplied here is insufficient to independently establish its complete product and respondent scope or the precise relationship between its patent claims and this new case.
- “Third complaint” and Amphenol: Insufficient evidence is available to verify the “third Vicor complaint in three years” count or Luxshare’s exact earlier assurances concerning the Amphenol patent case. The supplied Amphenol SEC filing concerns a dividend, not that litigation, and cannot support those assertions.
1
- Earlier company assurances would not, by themselves, establish the outcome of this separate investigation.
Next steps and when remedies become final
- Scheduling: The ITC sets a target completion date within 45 days after institution; that is a deadline for setting the timetable, not for finishing the investigation.
- Merits proceedings: An administrative law judge conducts the evidentiary process and hearing and issues an initial determination on whether Section 337 was violated; that determination is subject to possible full-commission review.
- Commission decision: Institution alone neither resolves the merits nor grants Vicor’s requested remedies; any relief depends on the subsequent findings and commission decision.
- Presidential review: If remedial orders issue, they are effective upon issuance but become final after the 60-day review period unless the US Trade Representative disapproves them for policy reasons under the presidential-review authority.
The key distinction is therefore between limited current commercial exposure and unresolved future legal exposure: Luxshare’s reassurance does not eliminate the possibility of remedies, while Vicor’s complaint and the ITC’s decision to investigate do not establish infringement.3
