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.

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 After the two failed to come to an agreement, Arm argued the designs licensed to Nuvia were no longer valid, and that Qualcomm should destroy the technology created with them.
