The Arm–Qualcomm trial began on December 16, 2024, in federal court in Delaware. It was a dispute over whether Qualcomm could use CPU technology developed by Nuvia—a chip-design company Qualcomm acquired—in reliance on Qualcomm’s existing Arm licenses, or whether the technology remained subject to Nuvia’s separate agreement with Arm. The case mattered to Qualcomm’s custom Oryon processors, including Snapdragon X chips for Windows PCs. “RISCy” was a computing pun, not a reference to RISC-V: this was an Arm licensing case.
The dispute in one sentence
After buying Nuvia, could Qualcomm use Nuvia-derived CPU designs under Qualcomm’s own Arm contracts, or did Arm’s separate license with Nuvia impose terms that still applied to that technology?
The question was not whether Qualcomm used Arm technology at all. Qualcomm licenses Arm technology. The disagreement was about which contractual license governed particular designs after the acquisition—and what each company was allowed to do under those agreements.

Why the Nuvia deal mattered
Arm licenses processor architecture and related technology to companies that build chips. Licensees can use Arm’s architecture while designing their own processors; Arm is not the maker of every chip that uses its architecture.

Nuvia, founded by former Apple chip engineers, was developing high-performance Arm-based CPU technology. Qualcomm announced its acquisition in January 2021 for about $1.4 billion; Qualcomm’s later filing identifies March 2021 as the acquisition date. The distinction matters: January was the announcement, not the reported closing.
Qualcomm wanted Nuvia’s people and technology to strengthen its custom CPU efforts. It incorporated Nuvia-derived work into its Oryon CPU program. Oryon powered Snapdragon X processors for Windows PCs and was part of Qualcomm’s broader plans for custom Arm-compatible CPUs. The dispute therefore had commercial significance beyond a narrow contract disagreement: Arm sought remedies that could affect use of technology Qualcomm said it had acquired and licensed.
Two licenses, two competing interpretations
Nuvia had an Arm architecture license agreement (ALA). Qualcomm had its own Arm ALA as well as a technology license agreement (TLA). Arm’s position was that Qualcomm could not simply acquire Nuvia and treat Nuvia’s separately licensed work as covered by Qualcomm’s different agreements. It alleged that the acquisition and subsequent use of the technology violated contractual requirements, including provisions governing consent, termination and what happened to technology developed under Nuvia’s license.

Qualcomm argued that its own Arm license covered the relevant CPU designs after the acquisition and that it had not breached the Nuvia agreement as Arm alleged. Qualcomm described Oryon as its custom CPU design, compliant with Arm architecture. Because the full licensing agreements were not publicly available, outsiders could not independently assess every disputed contract term; the companies’ competing interpretations should not be treated as established facts simply because either side stated them.

What Arm alleged—and what it sought
Arm alleged that Qualcomm had not obtained required consent for the transfer or use of Nuvia’s license, rejected the licensing terms associated with Nuvia, and continued using technology developed under that agreement after Arm terminated or sought to terminate Nuvia’s license in 2022. Arm’s filings describe allegations involving termination provisions and Qualcomm’s failure to destroy technology that Arm said had been developed under the Nuvia agreement.
Arm sought significant relief, including an order stopping use of disputed technology and requiring destruction of technology developed under Nuvia’s agreement. That is not the same as saying Arm asked a court to ban every Qualcomm chip or proved that all Snapdragon products infringed Arm rights. The claim concerned particular contractual rights and Nuvia-derived technology.

What the jury decided
The December 20, 2024 verdict was not a finding for Qualcomm on every question. The jury found that Qualcomm did not breach the Nuvia ALA and that Qualcomm CPUs incorporating technology acquired from Nuvia were covered by Qualcomm’s own Arm license. It could not reach a verdict on whether Nuvia itself had breached its agreement.
That deadlock left an issue for the court to address; it did not mean Arm had won that claim. Nor is it accurate to say the jury declared Arm’s entire case baseless. The jury answered particular questions about the contracts and disputed designs.

The later judgment and appeal
On September 30, 2025, the district court denied Arm’s renewed request for judgment as a matter of law or a new trial. It granted Nuvia judgment as a matter of law on Arm’s failure to prove harm and directed entry of final judgment. This resolved the remaining trial-level issue in Qualcomm and Nuvia’s favor.
Qualcomm reported that Arm filed a notice of appeal to the U.S. Court of Appeals for the Third Circuit on October 1, 2025. The notice means the case proceeded to appellate review; it does not establish that the appeal was decided. The available procedural record cited here does not establish a final appellate disposition, so the district-court result should not be described as the end of all possible litigation.

The case created legal uncertainty around Qualcomm’s ability to use specific Nuvia-derived technology—not an automatic shutdown order for all Snapdragon products. Snapdragon X PCs made the dispute especially visible because Oryon was central to Qualcomm’s effort to compete in Windows laptops with its own high-performance CPU design. Qualcomm also planned to use custom CPU technology in other Arm-based products.

More broadly, the dispute highlighted a tension in the chip industry. Arm relies on licensing its architecture and technology, while companies such as Qualcomm invest in custom CPU designs to differentiate products and control more of their chip road maps. When one licensee buys another, the treatment of existing licenses and previously developed technology can become strategically important. That is an implication of the case, not a broader legal rule established by the verdict.
Do not confuse it with Qualcomm’s separate case against Arm
Qualcomm filed a separate Delaware lawsuit against Arm in April 2024, alleging that Arm breached obligations under Qualcomm’s license, including by failing to provide contractual deliverables. Qualcomm later amended its claims to include allegations concerning Arm’s attempted termination actions and commercially reasonable licensing terms. This is a different case from Arm’s suit over Nuvia’s license and Qualcomm’s use of Nuvia-derived technology.
Qualcomm’s September 2025 filing said trial in that separate action was scheduled to begin on March 9, 2026. That date is a reported schedule, not proof that the trial took place then or that the case has since been resolved.
