Qualcomm is claiming victory in its court battle with chip design giant Arm after a jury in the US found that its processor designs are properly licensed. However, the case ended in a mistrial, leaving the door open for Arm to return with a fresh action.

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 After the two failed to come to an agreement, Arm argued the designs licensed to Nuvia were no longer valid, and that Qualcomm should destroy the technology created with them.
