The verdict followed a five-day trial in Wilmington, Delaware, in which Qualcomm accused Arm of violating its Architecture License Agreement (ALA), withholding software patches and processor verification tools, and refusing to offer commercially reasonable licensing terms. Qualcomm alleged that Arm deliberately withheld Arm Compliance Kit verification materials and software patches needed to validate its custom CPUs, and refused to renew licenses for Cortex-A720, Cortex-A520 and Cortex-M55 processor cores under its Technology License Agreement (TLA).
Qualcomm also argued that Arm sought to undermine its customer relationships by threatening to terminate its architecture license and leaking the corresponding notice to the media in October 2024, disrupting negotiations with Meta and causing it to lose contracts. Arm denied any wrongdoing, saying Qualcomm had failed to demonstrate substantial financial losses, and suggested the litigation was an attempt to obtain more favorable licensing terms and avoid billions of dollars in royalty payments.
The jury sided with Qualcomm on two issues: that Arm breached its longstanding ALA, and that it intentionally interfered with Qualcomm's business relationship with Meta. It awarded $1 in damages on each claim. Arm prevailed on four of the six claims submitted to the jury, which included additional allegations of TLA breaches, violations of the implied covenant of good faith and fair dealing, negligent interference with prospective economic advantage, and unfair competition.
"We are gratified that the jury found Arm breached its long-standing Architectural License Agreement with Qualcomm, failed to honor its commitments, and intentionally acted to disrupt Qualcomm's businesses," Qualcomm said in a statement. "Together with Qualcomm's prior court victory, this outcome further exposes Arm's broader intentions to harm Qualcomm and its ecosystem."
The case follows Qualcomm's earlier win in a separate licensing dispute with Arm over CPU cores developed by Nuvia, the chip designer Qualcomm acquired. Qualcomm then sued Arm in the U.S. early this year over the alleged contract breaches.
