Arm and Qualcomm clash over chip design rights
The legal battle in the US court could reshape the chip industry.

Attorneys for Arm and Qualcomm are clashing in a US federal court this week over a dispute that could shape the future of the chip industry. The case centres on whether Qualcomm’s acquisition of Nuvia in 2021 for $1.4 billion allowed the transfer of computing core designs that build on Arm’s architecture. Arm, whose technology dominates the smartphone market and is increasingly used in laptops, argues that Nuvia’s designs are derivatives of its intellectual property and fall under licensing restrictions.
At the heart of the trial is the testimony of Gerard Williams, a former Apple executive who founded Nuvia. While Arm’s attorneys contend that Nuvia’s work is derived from Arm’s technology, Williams insisted the influence of Arm’s architecture was minimal, estimating it made up ‘one percent or less’ of Nuvia’s final designs. Qualcomm’s lawyers are defending their right to use Nuvia’s cores, highlighting how the company customises and extends Arm’s technology.
The outcome of this trial could impact Qualcomm’s ambitions in the laptop market, where it partners with Microsoft to compete against Apple’s custom chips. With potential losses of $50 million annually in licensing fees for Arm at stake, both companies are vying for control over the boundaries of intellectual property rights. A verdict could come as early as this week, and Qualcomm’s CEO Cristiano Amon may soon take the stand.
