USITC launches patent probe into AI server power systems

The US International Trade Commission (USITC) has initiated a Section 337 investigation into several companies regarding the alleged infringement of vertical power delivery system patents. The probe follows a complaint filed by Massachusetts-based Vicor Corporation in September 2026.

The investigation targets products used in data center servers, artificial intelligence (AI) accelerators, and computing systems, including those powering GPUs, CPUs, and tensor processing units (TPUs).

The 20 named respondents include major international technology and manufacturing firms such as Delta Electronics, Hon Hai Precision Industry (Foxconn), Luxshare Precision, Infineon Technologies, Monolithic Power Systems, Flex, Celestica, and Quanta Computer.

The USITC noted that the commencement of this investigation does not constitute a final ruling on the merits of the case. An administrative law judge will be appointed to oversee hearings and issue a preliminary determination regarding potential violations of the Tariff Act of 1930.
