The judge presiding over the case, US District Court Judge Maryellen Noreika, said she didn't think "either side had a clear victory."

Arm's lawsuit against Qualcomm seemingly has failed as the latter was not found guilty of using Arm's tech without a proper license. However, the actual fate between the two companies remains unknown.

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 After the two failed to come to an agreement, Arm argued the designs licensed to Nuvia were no longer valid, and that Qualcomm should destroy the technology created with them.

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.

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.

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.
