No one seems to want Arm to sue Qualcomm.

Qualcomm obviously doesn’t, given that Arm’s suit last week asks for damages as well as the company to throw out the work that Nuvia, once the saving grace of Arm’s desktop processor ambitions, has put into place.

Microsoft shouldn’t, assuming that it still believes in a competitive hardware ecosystem for Windows on Arm that has been spearheaded by Qualcomm and its Snapdragon processors.

And Arm shouldn’t, either, given that Qualcomm has a chance to crack open the PC market, which is currently a toss-up between the rival X86 architectures of AMD and Intel. (Well, okay — neither one of these two companies would benefit from the increased competition.)

But here we are, with Arm threatening Qualcomm, one of its chief licensees, as the entire Snapdragon PC ecosystem sputters along while Nuvia works behind the scenes to save the day.

Neither Qualcomm nor Windows on Arm is down and out. But boy, a lawsuit is exactly what Qualcomm doesn’t need right now.

According to Reuters, Arm is seeking an injunction that would ask Qualcomm to “destroy” the designs that Nuvia is working on with Qualcomm. In 2021, Qualcomm bought the Nuvia design team and intellectual property. Nuvia has never announced a product, but the suspicion was that Nuvia was working on an Arm processor that could be used for both servers as well as mobile PCs, and perhaps even desktops.

Arm contends that it had separate business and licensing agreements with Nuvia and Qualcomm, and that Qualcomm was required to re-negotiate the agreement after it bought Nuvia. Qualcomm did not, and Arm says Nuvia’s work is therefore illegally using Arm’s intellectual property.

Windows on Arm with Qualcomm’s Snapdragon already suffered from two problems: a lack of pure performance and compatibility concerns. The latter, at least, has been largely solved. Still, Qualcomm’s Snapdragon processors already lag rival Intel badly in terms of performance; in PCWorld’s tests, the 2021 Snapdragon 8cx Gen 2
