A U.S. District Court judge has granted a complete victory to Qualcomm in a lawsuit brought by Arm. The ruling dismisses Arm’s claims that Qualcomm and its subsidiary, Nuvia, breached license agreements.
The decision, issued by the U.S. District Court for the District of Delaware, concludes a legal battle centered on Qualcomm’s acquisition of Nuvia. Arm had filed a lawsuit alleging that Qualcomm’s use of Nuvia’s technology constituted a breach of the architecture license agreement (ALA) between Nuvia and Arm.
This ruling affirms a unanimous jury verdict from a December 2024 trial. The jury found that Qualcomm had not breached the Nuvia ALA and that the CPU cores developed by Qualcomm, which incorporate technology from the Nuvia acquisition, were properly licensed under Qualcomm’s own separate agreement with Arm. The court has now upheld those jury findings, rejecting Arm’s attempts to have them overturned and denying its request for a new trial.
While this case has concluded, separate litigation between the two companies is ongoing. Qualcomm has filed its own lawsuit against Arm, alleging breach of contract and improper interference with customer relationships. That trial is expected to take place in March 2026. Arm said it plans to appeal.
Regarding this, Ann Chaplin, General Counsel & Corporate Secretary, Qualcomm Incorporated said:
With the Court’s decision today, Qualcomm and its subsidiary Nuvia have achieved a full victory. This decision follows Qualcomm’s December 2024 jury trial win and is a full and final judgment in Qualcomm’s favor. Our right to innovate prevailed in this case and we hope Arm will return to fair and competitive practices in dealing with the Arm ecosystem.
Arm said in a statement:
Arm remains confident in its position in its ongoing dispute with Qualcomm and will immediately file an appeal seeking to overturn the judgment.
