A US jury has found that Arm breached its long-standing Architectural Licence Agreement (ALA) with Qualcomm, a decision that deepens one of the semiconductor industry's most consequential legal disputes. The verdict, confirmed by Qualcomm in a statement dated 13 October, also determined that Arm intentionally acted to disrupt Qualcomm's business operations.

The damages figure, however, undercuts the scale of the rhetorical victory. The jury awarded Qualcomm just one dollar on each of its two remaining claims — a total of two dollars — while finding for Arm on four claims of its own.

The case has its roots in a dispute over custom CPU architectures, licensing rights and the deployment of advanced silicon design. Qualcomm had already characterised an earlier court ruling last year as a full victory in the broader legal battle, and this week's verdict extends that sequence of decisions in the US district court.

What does the verdict actually decide?

Legally, the jury's core finding is that Arm failed to honour its contractual commitments under the ALA, the foundational licence that governs how Qualcomm designs chips around Arm's processor architecture. The jury additionally found that Arm's conduct amounted to an intentional disruption of Qualcomm's business.

The monetary award is almost symbolic. Arm was quick to seize on that point, stating it was "pleased with jury's decision today finding for Arm on four claims and awarding only one dollar in damages on each of Qualcomm's other two claims".

Arm framed Qualcomm's litigation as an attempt to weaken its licensing position. "Despite Qualcomm's pursuit of this case in an attempt to deprive Arm of billions of dollars under our licence agreements, the jury's verdict confirms that Arm operated in good faith under its technology licence agreement and its award of only two dollars confirms the merit of Arm's arguments in the case," the company said.

How did Qualcomm respond?

Qualcomm cast the outcome as a win for market competition and for its own technology roadmap. The company connected the verdict to its previous court success, arguing the pattern reveals Arm's intentions toward its business and partners.

"Together with Qualcomm's prior court victory, this outcome further exposes Arm's broader intentions to harm Qualcomm and its ecosystem," Qualcomm said in its statement. "This outcome is a victory for innovation and competition, and we remain focused on developing and delivering industry-leading semiconductor products including our Oryon CPUs to customers and consumers worldwide."

The reference to Oryon CPUs is commercially significant. The custom CPU core family sits at the centre of the dispute over architectural licensing, and Qualcomm's statement signals that the verdict removes, in its view, a barrier to shipping those designs to customers at scale.

Who really won?

Both companies declared victory, and the split verdict gives each side material to support its claim. Qualcomm can point to the jury's finding of a breach and intentional interference — a reputational blow to Arm's licensing conduct. Arm can point to the two-dollar award as evidence that Qualcomm suffered no meaningful measurable harm, and to the four claims decided in its favour.

For an industry that depends on the Arm–Qualcomm relationship, the practical question is what happens to licensing terms between the two companies next. The dispute has already run through multiple rounds, including Qualcomm's claimed win last year, and this week's verdict narrows the legal ground left to contest.

Neither company indicated in its statements whether further proceedings or appeals are planned, and no new licensing settlement has been announced. What is clear is that the ruling keeps pressure on the commercial relationship behind a large share of the world's mobile silicon, with Qualcomm pledging to press ahead with Oryon-based products and Arm maintaining that it honoured its agreements.
