A license dispute between Arm Holdings , and Qualcomm went before a jury on Thursday after attorneys from both sides completed closing arguments.

It’s mine, no it is mine Attorneys representing Arm and Qualcomm grilled a former Apple executive in a pivotal legal battle over intellectual property (IP) ownership tied to Arm's computing architecture.

Qualcomm Inc.’s chief executive officer told a jury that its business suffered when customers were misled by computer-chip designer Arm Holdings Plc about the companies’ licensing agreement for chip technology vital to the electronics ecosystem.

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.
