Uncertainty looms over the impact of the trial's outcome on Qualcomm's business practices. The last week was a wild one for Qualcomm and Arm.

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

Internal Qualcomm documents showed the chip firm estimated it could eventually save as much as $1.4 billion a year on payments to Arm by purchasing a little-known startup in 2021, according to evidence shown at a trial on Wednesday.

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 After the two failed to come to an agreement, Arm argued the designs licensed to Nuvia were no longer valid, and that Qualcomm should destroy the technology created with them.

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.

A jury sided with Qualcomm on two of three key points, but couldn't reach a verdict on the third, resulting in a mistrial. The judge cautioned against a new trial and recommended mediation.

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.

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

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
