Morrison & Foerster and Young Conaway Stargatt & Taylor are representing U.K. microprocessor designer Arm Ltd. in a licensing and trademark dispute with wireless giant Qualcomm Inc.

Arm alleges that it licensed its processor architecture in 2019 to Santa Clara startup Nuvia Inc., which was working on an energy-efficient central processing unit, or CPU, for data center servers. A year later Nuvia announced “a custom core based on the ARM architecture.”
