Qualcomm won the central district-court case over Arm licenses and CPU designs developed by Nuvia, but the dispute is not over: Arm appealed, and a separate Qualcomm lawsuit against Arm remains active. Qualcomm’s “complete victory” description refers to the outcome in the trial court, not the end of every legal dispute between the companies.
What Qualcomm won in the Delaware case
The case concerned whether Qualcomm could use Nuvia-developed CPU designs under Qualcomm’s own agreements with Arm after Qualcomm acquired Nuvia in 2021. On December 20, 2024, a jury found that Qualcomm had not breached Nuvia’s Architecture License Agreement (ALA) and that Qualcomm CPUs incorporating the relevant Nuvia-derived designs were covered by Qualcomm’s ALA.

The jury did not reach a complete verdict: it left unresolved whether Nuvia itself had breached its separate agreement with Arm. On September 30, 2025, the judge entered judgment for Nuvia on that remaining issue, upheld the favorable jury findings, dismissed Arm’s remaining claims, and rejected Arm’s request for a new trial. Qualcomm announced the result as a “complete victory” on October 1, 2025. Qualcomm’s trial statement and its October 2025 announcement describe those outcomes.
Why Nuvia and Oryon were at the center
Nuvia, a CPU-design startup founded by former Apple engineers, held its own Arm ALA. Qualcomm acquired the company in 2021 and drew on its engineering and designs for custom CPUs, including Oryon-based processors. Arm argued that Nuvia’s licensed technology could not simply be transferred or used after the acquisition without Arm’s consent or without meeting the agreement’s termination requirements.

The contractual distinction matters. An ALA grants rights related to implementing Arm’s instruction-set architecture; it is not the same as a license to use Arm-developed technology or implementation materials. Qualcomm also has a Technology License Agreement (TLA). The dispute involved Nuvia’s ALA, Qualcomm’s ALA, and Qualcomm’s TLA, but the district-court judgment supports Qualcomm’s position only as to the relevant Nuvia-derived designs and agreements at issue. It does not mean Qualcomm owns Arm’s architecture or has unrestricted rights to every Arm-compatible design. Arm’s annual-report filing describes the agreements and litigation.
What the judgment means for Qualcomm’s chips
The district-court result removes the immediate threat posed by Arm’s claims in that case and supports Qualcomm’s ability to use the relevant Nuvia-derived designs under Qualcomm’s license. That is strategically important to Qualcomm’s custom-CPU roadmap, which reaches markets including phones, PCs, and automotive systems.

It is not a ruling on processor performance, sales, market share, or customer adoption. Nor does it decide every possible future disagreement about new designs, different conduct, or later contractual obligations. Qualcomm remains subject to its agreements with Arm, and the judgment does not make every Qualcomm product immune from future Arm-related claims.
Why “complete victory” has a limited scope
Qualcomm’s phrase describes the final disposition of Arm’s claims in the Delaware district court. It is not a neutral label for the overall relationship: the jury initially left one issue open, the judge resolved it later, and Arm then appealed. A trial-court judgment can be final at that level while still being reviewed by an appellate court.

Arm filed a notice of appeal to the U.S. Court of Appeals for the Third Circuit on October 1, 2025. Qualcomm and Arm later described the appeal as pending. An appeal generally examines alleged legal or procedural errors rather than retrying the entire case from the beginning; the cited filings do not establish how the appeal will be decided. See the companies’ Qualcomm filing and Arm filing.

Qualcomm filed a separate Delaware action against Arm on April 18, 2024. Qualcomm alleges, among other things, that Arm failed to provide contractual deliverables, improperly sought or threatened to terminate Qualcomm’s ALA, publicized its termination position, and failed to offer TLA licenses on commercially reasonable prices and terms. These are Qualcomm’s allegations, not findings in the Nuvia case.

Qualcomm amended its complaint in December 2024 and June 2025. In January 2026, it filed a substantially similar complaint against Arm Limited, and the matters were later consolidated. Qualcomm’s March 2026 filing scheduled trial for October 5, 2026; that is a filed schedule, not a guarantee the trial will occur on that date. Arm’s annual-report filing also describes the separate action and its expected timing.

Arm issued Qualcomm a breach notice on October 22, 2024, alleging breaches related to Qualcomm’s marketing and use of CPUs containing Nuvia-related designs, requests for Arm support or verification, and Qualcomm’s own lawsuit. Qualcomm disputed the allegations. On January 8, 2025, Arm withdrew the notice and said it had no current plan to terminate Qualcomm’s ALA, while reserving its rights. The withdrawal removed that immediate notice; it did not settle the companies’ broader contractual disagreements. Qualcomm’s filing recounts the notice and withdrawal.
Quick Recap
What the case may mean for the industry
- Custom CPU investment: The judgment gives Qualcomm a stronger legal footing for the Nuvia-derived designs covered by the case, but it does not guarantee the commercial success of Oryon products.
- Licensing certainty: The result may reassure companies that the effect of an acquisition on architecture-license rights depends on the contract and facts involved. It does not create a universal rule that all such rights transfer automatically.
- Arm’s licensing model: The dispute highlights tensions between Arm’s licensing arrangements and customers seeking to build more differentiated processors. The judgment did not invalidate Arm’s model or prevent Arm from enforcing its contracts.
- Negotiating leverage: The appeal and Qualcomm’s separate claims leave important contractual questions unresolved, including deliverables and licensing terms. Their outcome could affect the companies’ negotiating positions, but it is not yet known.
