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.

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.

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.
