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.

Qualcomm's central processors are properly licensed under an agreement with Arm Holdings, a jury found in a trial in U.S. federal court that removed some, but not all, uncertainty around the mobile chipmaker's expansion into the laptop market.

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