ITC expands Section 337 vehicle parts investigation to 16 additional respondents across three patent claims

Executive Summary

The U.S. International Trade Commission declined to review an ALJ order on June 24, 2026, granting an unopposed motion to amend the complaint in an active Section 337 investigation into certain vehicle parts. The amendment adds 16 new respondents and extends design patent infringement allegations to five existing respondents across three U.S. design patents.

Bottom Line

The Commission's decision not to review the ALJ order makes the amendment final and operative. All 16 newly named entities are now active respondents subject to ITC process, discovery obligations, and potential exclusion order exposure. The five existing respondents facing new patent claims must now defend against a broader set of allegations than those in the original complaint. Domestic distributors named in the amendment are not shielded from exclusion order risk by their U.S. location.

Key Regulatory Signals

Respondent Pool Expands Significantly: Sixteen entities are now named respondents, including manufacturers and distributors based in China, Taiwan, and the United States. Each newly added party carries full respondent status and the associated litigation obligations from the date of the amendment.
Three Design Patents Now in Play: The investigation now asserts three U.S. design patents covering vehicle parts. Existing respondents ANTRC, Jiangsu Srumto, Quality Collision, Power Auto, and Tong Yang each face newly added patent claims beyond those originally alleged against them.
U.S.-Based Distributors Named: Two Warren, Michigan distributors, Quality Collision Parts and Power Auto Parts, are now subject to design patent infringement allegations. Domestic distributors of aftermarket vehicle parts sourced from named foreign manufacturers carry direct ITC exposure under this amendment.
Unopposed Amendment Signals Broad Complainant Confidence: The motion to amend was unopposed, and the Commission declined to review the ALJ's grant. This procedural posture accelerates the investigation's expansion without the delay of contested briefing, leaving newly named respondents with limited runway to prepare a response.

Regulatory Delta

- This amendment follows the standard ITC practice of expanding Section 337 investigations as complainants identify additional infringers, consistent with prior vehicle-parts proceedings.

- Adding 16 respondents in a single amendment is a materially larger expansion than typical mid-investigation amendments, which more commonly add two to five parties.

- No directly parallel Congressional or cross-agency action is currently pending that would alter the ITC's Section 337 jurisdiction over design patent claims in the automotive aftermarket.
