The U.S. International Trade Commission published a notice of institution on October 14, 2026, for Investigation No. 337-TA-1526, Certain Vertical Power Delivery Systems, Components Thereof, and Computing Systems Containing the Same. The Commission ordered the investigation on October 9, 2026, on a complaint Vicor Corporation of Andover, Massachusetts filed September 9, 2026, and supplemented September 10 (91 Fed. Reg. 65254-65256). Under 19 CFR 210.10(b)(1), an investigation is instituted by publication of the notice in the Federal Register.

Reg. 65255). The patent is titled "Delivering Power to Semiconductor Loads." The complaint requests a limited exclusion order and cease and desist orders (91 Fed. Reg. 65255).

Accused products and respondents

The notice's plain language description of the accused products is "vertical power delivery systems and components thereof, used in data center server, artificial intelligence and cloud computing systems, to power artificial intelligence ('AI') accelerators, tensor processing units ('TPU'), graphical processing units ('GPU') and central processing units ('CPU'), and computing systems containing the same" (91 Fed. Reg. 65255).

The notice names 20 respondents, including Delta Electronics, Inc., Infineon Technologies AG, Luxshare Precision Industry Co., Ltd., Monolithic Power Systems, Inc., Flex Ltd., Celestica Inc., Quanta Computer Inc., Hon Hai Precision Industry Co. Ltd. (d/b/a Foxconn), and Ingrasys Technology Inc. (91 Fed. Reg. 65255).

What the notice asks for next

The Office of Unfair Import Investigations will not participate as a party. The Commission said it is interested in the development of a thorough record on domestic industry, and that the presiding administrative law judge may wish to consider the extent to which Vicor's domestic industry allegations rely on expenditures made by third parties, and the extent to which expenditures are made outside the United States related to the domestic industry article(s) by any entity (91 Fed. Reg. 65255). Respondents' responses will be considered if received not later than 20 days after the Commission serves the complaint and notice, under 19 CFR 201.16(e) and 210.13(a) (91 Fed. Reg. 65255).
