In October, Arm cancelled Qualcomm’s license to the Nuvia ALA. It also demanded the destruction of Nuvia designs developed prior to the merger. Clearly, a verdict in favor of Arm would put Qualcomm in a tight corner, and also a who’s who of tech companies — Microsoft, Acer, Asus, Dell, HP, Lenovo, and Samsung — currently using Qualcomm’s Snapdragon designs.

This week, Qualcomm put forward an alternative view to explain Arm’s motivations. According to Qualcomm’s lawyers, Arm harbors ambitions to develop competing chips of its own, making it a direct competitor to Qualcomm. Evidence for this remains circumstantial, but to back this up Qualcomm claimed that Arm at one point misled it into disbanding its development team.

Stop being cheap

A difficulty for outsiders is untangling exactly what is really at issue and whether there’s more to this than meets the eye. According to Arm it’s about licensing agreements and the fees that arise from them. It believes Qualcomm used its IP in Nuvia-originated IP and should pay what Nuvia agreed and stop being cheap.
