Qualcomm is claiming complete victory over Arm in their licensing spat, after a court in Delaware ruled it has not breached the terms of any architecture license agreement (ALA) with the chip designer.
This latest [1]verdict [PDF] follows the court case at the end of last year, when [2]a jury found largely in favor of the California chipmaker . This legal row concerned whether Qualcomm had broken the terms of its licenses with Arm when it [3]acquired Nuvia , a startup developing Arm-based processors for the datacenter, and incorporated its technology into Qualcomm chips.
In those hearings, the jury was unable to reach a consensus on whether Nuvia had breached its own ALA with Arm. The final ruling this week by District Judge Maryellen Noreika finds in favor of Nuvia and Qualcomm, that Nuvia did not in fact breach its ALA with the UK-based chip designer.
[4]
This means that for the three issues raised in the December trial, the court has come down on the side of Qualcomm's in each case. As detailed previously, these were:
Did Arm prove that Nuvia had breached the terms of its architecture license agreement (ALA) with Arm?
Did Arm prove that Qualcomm breached the terms of Nuvia's ALA?
Did Qualcomm prove that its CPUs that include designs acquired in the Nuvia acquisition were licensed under its ALA?
"With the Court's decision today, Qualcomm and its subsidiary Nuvia have achieved a full victory," said Qualcomm's General Counsel & Corporate Secretary Ann Chaplin.
"This decision follows Qualcomm's December 2024 jury trial win and is a full and final judgment in Qualcomm's favor. Our right to innovate prevailed in this case and we hope Arm will return to fair and competitive practices in dealing with the Arm ecosystem," she added.
[5]
[6]
However, Arm indicated that it intends to appeal against the verdict.
"Arm remains confident in its position in its ongoing dispute with Qualcomm and will immediately file an appeal seeking to overturn the judgment," the company said in a statement sent to The Register .
[7]
This would seem to be at odds with Qualcomm's view of things, as its CEO Cristiano Amon told a [8]conference call for investors earlier this year that Arm "has no current plan to terminate the Qualcomm Architecture License Agreement."
The crux of this legal battle centered on whether Qualcomm had the right to use Nuvia's technology after acquiring the company, despite Qualy already having licenses of its own.
Arm took the view that the licenses it had granted to Nuvia to design its own Arm-based chips could not simply be transferred to Qualcomm without its permission, and this would breach the license terms.
[9]
The Brit-based biz claimed Qualcomm had not obtained consent or a new licensing agreement, despite lengthy negotiations, but had pushed ahead with incorporating Nuvia technology into its chips, such as the Snapdragon X Elite used in laptops.
For its part, Qualcomm alleged Arm's lawsuit was [10]"payback" for its earlier opposition to [11]Nvidia's bid to buy the UK chip designer , which ultimately failed. It has also claimed Arm is aiming to [12]produce its own datacenter processors , and sought to nobble Qualcomm as a potential rival in this market.

[15]Arm gives up on killing off Qualcomm's vital chip license
[16]Jury spares Qualcomm's AI PC ambitions, but Arm eyes a retrial
Neil Shah, Research VP at Counterpoint Research, said this court ruling is "monumental for Qualcomm," clearing the way for it to accelerate deployment of custom Nuvia-based CPU cores across a much broader spectrum of applications from PCs, smartphones, and automotive to high-performance computing domains like AI servers.
"While Arm's decision to pursue legal action was an understandable measure to protect its business, it was an unfortunate necessity that strained its relationship with a premier customer and partner," he said.
"Moving forward, it is imperative for Arm to seize this opportunity to mend fences and rebuild trust with Qualcomm," Shahn added, as it is a critical player in the Arm market.
Qualcomm's counter lawsuit against Arm for breach of contract and improper interference, which it [17]filed [PDF] in April 2024, is still ongoing, with a trial expected in March 2026, so this entire saga is not over just yet. ®

Re: How silly, Arm
Jason Bloomberg
I understand the sentiment but I agree with the verdict and expect it would have been the same under any non-biased jurisdiction.
Qualcomm found a way to advantage themselves which ARM took exception to and didn't like the idea of losing huge licensing payments they believed they deserved.
As the court has found, and I agree, they don't and didn't.
I'm not going to shed tears for any ruthless money grabbing Capitalist Bastard stopped in their tracks..

It's not too late for the world to pivot from Arm to RISC-V
Re: Goose, golden, egg

My employer (very large company you’ve heard of) is getting its first RISC-V silicon samples back shortly. ARM has screwed the pooch.

No but it's apparently impossible for people working on RISC-V to avoid poking the Torvalds bear.

So your magic ISA is little endian but it's not guaranteed that an instruction to byte swap data to big endian exists? Yeah good luck with that.

I really don't know what the execs at ARM were thinking when they decided to go after one of their largest ARM licensees, I can only think they imagining the dollar signs in their yearly bonus should they have won the case.
All it was ever going to achieve even if ARM won, is to make Qualcomm and other licensees think more seriously about adopting RISC-V in their future SOC to get out from underneath ARMs thumb. So it was only ever going to be a short term win.
How silly, Arm
Arm sued an American company in an American court. What did it expect?
