Reports said a five-day jury trial in Qualcomm’s separate contract dispute with Arm began in Delaware on October 5, 2026. Qualcomm alleges that Arm withheld chip-testing tools required under their contract and disclosed a 2024 threat to terminate a license agreement. Qualcomm says the disclosure harmed its negotiations with Meta Platforms for a chip deal.

The action was filed by Qualcomm Incorporated and Qualcomm Technologies, Inc. against ARM Holdings PLC in the U.S. District Court for the District of Delaware. The case docket identifies it as No. 1:24-cv-00490.

What Qualcomm alleges—and Arm’s response

Qualcomm’s claims concern access to chip-testing tools and the disclosure of the license threat. Arm denies breaching the contract and argues that the alleged harm to Qualcomm’s prospective chip deals is speculative. Arm also argues that Qualcomm should not recover damages over the alleged disclosure because Qualcomm itself disclosed confidential information about antitrust investigations involving Arm.

The royalty remedy Qualcomm is seeking

Qualcomm is asking to stop paying Arm royalties for up to five years. The royalties at issue have been described as potentially worth billions of dollars; that figure concerns the potential scope of the requested remedy.

A separate case from Arm’s earlier lawsuit

This action is distinct from Arm’s earlier case involving Qualcomm and Nuvia over a license agreement. Qualcomm said a final judgment for Qualcomm and Nuvia was entered in that case on September 30, 2025, after the court rejected Arm’s remaining claim and request for a new trial. Qualcomm’s statement about that judgment also said its separate lawsuit against Arm remained ongoing.
