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

Arm has lost a battle over licensing of its microprocessor designs to Qualcomm, ending doubt over the immediate future of some of the chip maker's products.

The jury in the US District Court for the District of Delaware spent the week listening to arguments in the protracted and increasingly rancorous licensing dispute between Arm and Qualcomm over whether Qualcomm is properly licensed to use technology acquired when it bought startup Nuvia in 2021.

The verdict, delivered Friday, is hugely significant, not only for the parties involved but for the maze of other companies that have built their product development around their technology, however, the battle is not over yet. Although the jury found that Qualcomm did not breach Nuvia's license with Arm, and Qualcomm's chips using Nuvia technology are properly licensed, it could not agree on whether Nuvia had breached the terms of its license with Arm. That means there could potentially be yet another trial.
