Arm Holdings announced plans to appeal a U.S. federal judge's decision in its high-profile licensing dispute with Qualcomm. The ruling, issued by Judge Maryellen Noreika in Delaware, left intact a jury verdict that largely favored Qualcomm, strengthening the chipmaker's position in the case.

The dispute centers around Qualcomm's subsidiary, Nuvia, and whether the central processing units it developed were properly licensed under an agreement with Arm. Last year, a jury found that Qualcomm had not violated its licensing terms, siding with the company on two of three counts. The jury deadlocked on the third count, resulting in a mistrial.

Arm had sought to overturn the verdict by requesting either a dismissal of Qualcomm's victories or a new trial. However, the judge denied both motions, solidifying Qualcomm's courtroom win. Following the decision, Arm stated it "remains confident in its position" and will promptly pursue an appeal to overturn the judgment.

Qualcomm, on the other hand, welcomed the ruling. Ann Chaplin, the company's general counsel, emphasized that the verdict validated Qualcomm's approach to innovation. "Our right to innovate prevailed in this case and we hope Arm will return to fair and competitive practices in dealing with the Arm ecosystem," she said.

The outcome of this case carries significant weight in the semiconductor industry. Arm is a critical technology supplier for Qualcomm, as well as other leading chipmakers including Apple and Taiwan's MediaTek. Arm's architecture underpins billions of devices worldwide, making the licensing agreements central to the broader chip ecosystem.

The forthcoming appeal will keep the legal battle ongoing, potentially shaping how licensing terms are interpreted and enforced in the rapidly evolving semiconductor sector. As the conflict continues, the industry is closely watching to see how the balance between chip innovation and licensing rights unfolds.
