U.S. Trade Commission Launches Patent Investigation into Computing Devices

Estimated reading time: 4–6 minutes

On February 11, 2026, the U.S. International Trade Commission (ITC) voted to begin an investigation under Section 337 of the Tariff Act of 1930.

This comes after a complaint was filed on January 12, 2026, by Vicor Corporation of Andover, Massachusetts. The complaint was later updated on January 21, January 23, and January 26, 2026. A revised version was submitted on January 27, 2026.

The complaint says that certain companies are importing, selling, or offering for sale in the U.S. power converters, circuit board assemblies, and computing systems that contain these parts. Vicor believes these products break the law by infringing on its U.S. Patent No. 12,395,087.

According to Vicor, these violations involve numerous claims under the ‘087 patent. Vicor also states that a U.S. industry exists and is being harmed.

The ITC agreed to start this investigation to see if a violation of Section 337(a)(1)(B) has happened. This section focuses on products that are imported, sold for import, or sold in the U.S. after import that infringe on intellectual property rights.

The products under investigation are:

  • Power converters used in data center servers, artificial intelligence (AI) systems, and cloud computing setups.

These power converters provide power to:

  • AI accelerators,
  • Tensor Processing Units (TPUs),
  • Graphics Processing Units (GPUs), and
  • Central Processing Units (CPUs).

Also included are circuit board assemblies and computing systems that include these converters.

Vicor requests that the ITC issue:

  • A limited exclusion order,
  • Cease and desist orders against the accused companies.

The accused parties are:

  • Delta Electronics, Inc. (Taiwan)
  • Delta Electronics (Americas) Ltd. (Fremont, CA)
  • DET Logistics (USA) Corporation (Fremont, CA)
  • Luxshare Precision Industry Co., Ltd. (Dongguan, China)
  • Dongguan Luxshare Technology Co., Ltd. (also known as Luxshare-Tech) (Dongguan, China)
  • Shanghai Peiyuan Electronics Co., Ltd. (also known as MetaPWR Electronics Co., Ltd.) (Shanghai, China)
  • Monolithic Power Systems, Inc. (Kirkland, WA)
  • Chengdu Monolithic Power Systems Co., Ltd. (Chengdu, China)
  • MPS International (Shanghai) Ltd. (Shanghai, China)
  • Wistron Corporation (Taipei, Taiwan)
  • Wiwynn Corporation (New Taipei City, Taiwan)
  • Quanta Computer Inc. (Taoyuan, Taiwan)
  • Quanta Cloud Technology Inc. (Taoyuan, Taiwan)
  • Quanta Cloud Technology USA LLC (San Jose, CA)
  • Quanta Computer USA Inc. (Fremont, CA)

The Commission assigned the Chief Administrative Law Judge to appoint an Administrative Law Judge for this case.

The Office of Unfair Import Investigations will not be part of the case.

The accused companies must respond within 20 days of being served with the complaint and the notice of investigation. This is in line with Rule 210.13 of the Commission’s Rules of Practice and Procedure.

If a company does not respond in time, it may lose its right to contest the claims. A result could be the issuing of an exclusion order or cease and desist orders without further warning.

For public access, the complaint (excluding confidential information) is available on the Commission’s electronic docket system at https://edis.usitc.gov.
