Qualcomm won the key licensing questions in the 2024 trial over technology it acquired from Nuvia, and a 2025 court judgment ruled for Nuvia on Arm’s failure to prove harm. But the result did not decide every issue: the jury deadlocked on whether Nuvia breached its own Arm license, Arm’s appeal is pending, and a separate Qualcomm–Arm lawsuit remains active. The dispute matters to Qualcomm’s Oryon CPU designs, but it is not a ruling that every product or future use is settled.
What was the ARM vs. Qualcomm lawsuit about?
Arm’s original case was a contract and licensing dispute, not a challenge to Arm’s ownership of its instruction-set architecture (ISA). An ISA is a specification of instructions that a processor can execute. Arm licenses its ISAs and documents them in architecture reference manuals that engineers use when designing CPUs.
The dispute arose after Qualcomm acquired Nuvia, a chip-design startup, in 2021. Reuters described the acquisition value as $1.4 billion in 2024. Nuvia had an Arm Architecture License Agreement (ALA). Arm argued that Qualcomm’s acquisition attempted to transfer that license without Arm’s consent, triggering termination provisions. Qualcomm countered that its own Qualcomm ALA covered the relevant technology and products, including architected cores developed with Nuvia technology.
Arm said it notified Nuvia in March 2022 that its ALA would terminate effective March 1, 2022. In its August 31, 2022 statement, Arm said the attempted transfer without consent caused Nuvia’s licenses to terminate. Arm then sued Qualcomm, Qualcomm Technologies and Nuvia in the U.S. District Court for the District of Delaware, alleging license breaches and trademark infringement. It sought specific performance, including an order to stop using or destroy certain Nuvia-developed designs.

What happened in the original case?
- 2021 — Qualcomm acquired Nuvia. The acquisition put Nuvia’s Arm license and its CPU-design work at the center of the dispute.
- March 2022 — Arm gave notice of termination. Arm said Nuvia’s license would terminate effective March 1 because the license had been transferred or used without required consent.
- August 31, 2022 — Arm filed suit. Arm alleged that Qualcomm and Nuvia breached license terms and also asserted trademark infringement. Qualcomm denied that its use was unlicensed.
- December 16–20, 2024 — The case went to trial. The jury found that Qualcomm had not breached the Nuvia ALA and that Qualcomm’s use of the relevant Arm code was licensed under Qualcomm’s ALA. It did not reach a verdict on whether Nuvia itself breached its ALA.
- September 30, 2025 — The court entered post-trial judgment. Judge Maryellen Noreika denied Arm’s renewed request for judgment or a new trial, granted Nuvia judgment as a matter of law because Arm had failed to prove harm, and directed final judgment. Arm’s FY2026 report says its appeal to the Third Circuit is pending.
Did Qualcomm win the Arm lawsuit?
Qualcomm prevailed on the central questions about its own license, but “Qualcomm won everything” would overstate the result. The jury’s findings resolved whether Qualcomm breached the Nuvia agreement and whether Qualcomm’s ALA licensed the relevant Arm code in Qualcomm’s use. The jury did not decide Nuvia’s separate breach question; the subsequent judgment for Nuvia rested on Arm’s failure to prove harm. Arm’s appeal means the original case is not fully beyond challenge.
| Issue | What the available rulings establish |
|---|---|
| Qualcomm’s alleged breach of the Nuvia ALA | The jury found Qualcomm had not breached it. |
| Whether Qualcomm’s ALA covered its use of relevant Arm code | The jury found that the use was licensed under Qualcomm’s ALA. |
| Whether Nuvia breached its own ALA | The jury did not reach a verdict. The court later granted Nuvia judgment as a matter of law because Arm had not proved harm. |
| Arm’s trademark allegations | Arm also pleaded trademark infringement. The contract and licensing findings described above do not establish a separate trademark verdict. |
| Appeal | Arm’s Third Circuit appeal was pending in Arm’s FY2026 report. |
The stated rulings do not establish a damages total, royalty rate or settlement amount. They also do not resolve the pending appeal.

Can Qualcomm still use Oryon cores?
The verdict supports Qualcomm’s position that its own Arm license covered the relevant Arm code used in the disputed designs. Oryon is the CPU family associated with Qualcomm’s designs and the Nuvia technology at issue, so the result is significant to Qualcomm’s ability to develop and ship Arm-based processors, including laptop and AI-PC chips.
That is not the same as a blanket court ruling on every Oryon design, product or future use. The appeal remains pending, and the verdict addressed the specific license questions and uses presented in this case. For consumers considering an Arm-based Windows computer, the dispute by itself does not establish that a particular product is unlawful, unavailable, or more or less capable.

What is the separate Qualcomm–Arm case?
Qualcomm filed a separate action against Arm on April 18, 2024. Arm’s FY2026 report says that action was consolidated with a later Arm Limited case in March 2026, and that Qualcomm amended its complaint on March 30, 2026. Arm said the matter was expected to go to trial in Q4 2026. That is a company-reported schedule, not a guaranteed trial date, and this separate case should not be confused with the 2022 lawsuit’s verdict and appeal.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What does the dispute mean for consumers and the chip market?
The direct stakes are contractual rights to use Arm technology in CPU designs, rather than a finding that Arm’s ISA belongs to Qualcomm or that all Arm-based devices are affected. The dispute has drawn attention because Qualcomm’s Oryon processors feature in laptop and AI-PC products. However, the court rulings do not predict product prices, availability, performance, or future licensing terms. Those outcomes are not established by the verdict.
