A jury in U.S. federal court in Delaware on Friday said it was deadlocked on one of the questions that it has been asked to resolve in Arm Holdings' lawsuit against Qualcomm, but is still deliberating the two other questions before it.

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.

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

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.
