The jury delivered its decision Friday in an industry-defining licensing battle that started over a $50 million royalty dispute.

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 After the two failed to come to an agreement, Arm argued the designs licensed to Nuvia were no longer valid, and that Qualcomm should destroy the technology created with them.

A federal jury in the United States on Friday delivered a key win to mobile commputing titan Qualcomm in a licensing dispute with Arm, although proceedings between the chipmakers ended in mistrial.

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.

Mobile-phone chip giant Qualcomm largely prevailed Friday in a licensing dispute with chip design firm Arm Holdings. A Delaware jury ruled that Qualcomm had a valid license to use Arm’s basic chip architecture for central processors it developed with the acquisition of a startup called Nuvia in 2021.

Arm Holdings' lawsuit against Qualcomm ended on Friday with a jury delivering a mixed verdict that found for Qualcomm on a crucial issue, saying Qualcomm had properly licensed its central processor chips.
