In 2022, Arm ignited a legal battle after Qualcomm continued to pay its existing royalty fees to Arm, which were allegedly much lower than what Nuvia was paying. After the two failed to come to an agreement, Arm argued the designs licensed to Nuvia were no longer valid, and that Qualcomm should destroy the technology created with them.

Qualcomm Inc. prevailed at trial against Arm Holdings Plc’s claim that it breached a license for chip technology that the world’s largest maker of mobile-phone processors acquired when it bought a startup in 2021.
