Estimated reading time: 3–5 minutes
WASHINGTON D.C., October 14, 2026 – The United States International Trade Commission (USITC) has announced the start of an investigation concerning certain vertical power delivery systems and their related components. The investigation also includes computing systems that use these components.
The investigation, numbered 337-TA-1526, comes after a complaint filed on September 9, 2026, by Vicor Corporation. Vicor is based in Andover, Massachusetts. They allege that certain imported products violate section 337 of the Tariff Act of 1930. They believe these products infringe on specific claims of the U.S. Patent No. 10,903,734.
The products at the heart of this case are used in data centers and artificial intelligence systems. They help power AI accelerators, tensor processing units, graphical processing units, and central processing units.
The USITC wants to determine if an industry within the United States is affected by this alleged infringement. The Commission will consider several key claims of the ‘734 patent.
Vicor Corporation is requesting that the Commission issue an exclusion order and cease and desist orders if a violation is confirmed.
The investigation will look at whether companies such as Delta Electronics, Infineon Technologies, Luxshare Precision Industry, Monolithic Power Systems, Flex Ltd., Celestica Inc., Quanta Computer, Hon Hai Precision Industry (Foxconn), and others are involved. These companies are accused of importing or selling the infringing products in the United States.
The Chief Administrative Law Judge of the USITC will appoint the presiding Administrative Law Judge for the case. The Commission aims to develop a complete record concerning the domestic industry involved.
The accused companies must respond to the complaint and notice within 20 days. Failure to do so might lead to a default judgment against them. The Commission may then issue exclusion or cease and desist orders without further notice.
The investigation aims to protect domestic industries and ensure that U.S. patents are upheld.
For further details, interested persons can view the complaint on the Commission’s electronic docket. Assistance is available for anyone needing help accessing these documents.
The USITC continues to support fair trade practices and protect U.S. industries from unfair competition due to patent violations.
