In 2022 Patently Apple posted a report titled " Apple chip design supplier ARM is Suing Qualcomm and NUVIA for breach of license agreements and trademark infringement." The report noted that "Arm is seeking specific performance of the contractual obligation to destroy certain Nuvia designs, an injunction against trademark infringement as well as fair compensation for the trademark infringement."

We're now learning that Arm Holdings is cancelling an architectural license agreement that allows Qualcomm to use intellectual property to design chips, amid an ongoing legal battle between the two companies, Bloomberg News reports.

Arm has given Qualcomm a mandated 60-day notice of the cancellation of the licensing agreement. Arm had previously said the current design planned for Microsoft's Copilot+ laptops is a direct technical descendant of Nuvia's chip and it had cancelled the license for these chips.

The legal battle between the two tech giants is scheduled to begin in the federal court in Delaware in December.

An Arm victory in the litigation could force Qualcomm and its roughly 20 partners, including Microsoft, to halt shipments of the new Copilot laptops. It would also essentially unwind one of Qualcomm's biggest strategic acquisitions in recent years. 

A Qualcomm spokesperson said in an emailed statement: "This is more of the same from ARM – more unfounded threats designed to strongarm a longtime partner, interfere with our performance-leading CPUs, and increase royalty rates regardless of the broad rights under our architecture license."

Qualcomm's 'Snapdragon X Elite' (Oryon based) was derived  from a group of top-tier engineers that left Apple to start their own company called NUVIA. Qualcomm has been claiming that their new PC chip is more powerful than Apple's M-Series processors. The battle will continue with Apple's new M4 chip arriving next month in Macs.
