This week, Qualcomm scored a big legal win over Arm in a complex licensing fight. The US District Court judge in Delaware, Maryellen Noreika, ruled in Qualcomm’s favor on the final claim in the case. This decision came after a jury had already found in Qualcomm’s favor back in December 2024 on most counts. The last remaining claim was about whether Qualcomm or its acquisition, Nuvia, breached an architecture license agreement, or ALA.

In her ruling, Judge Noreika said neither Qualcomm nor Nuvia broke the licensing rules. Arm had argued that its technology was being used without proper licensing, which they said hurt their ecosystem. But the court disagreed and dismissed Arm’s claim. The judge’s opinion explained that Qualcomm’s use of Nuvia’s technology was properly licensed under their own agreement. This decision wrapped up the case in Qualcomm’s favor once and for all.

Qualcomm’s side called this a complete victory. Ann Chaplin, their general counsel, said the court’s ruling confirms their right to innovate and that they hope Arm will play fair in the future. Qualcomm also pointed out that the court previously found no breach related to their CPU cores using Nuvia tech, reinforcing their position.

Arm, meanwhile, isn’t giving up. The company’s spokesperson said they are confident in their stance and have already filed an appeal to challenge the court’s decision. They want to overturn the ruling and continue fighting. This move shows that, even after a big court win, Arm isn’t finished with the legal battle.

Industry experts see this case as a sign of ongoing tension between the two giants. Anshel Sag, a VP at Moor Insights & Strategy, noted that Qualcomm appears to believe the issue is settled, but Arm clearly disagrees. He pointed out that Arm has already filed its appeal and that the dispute might be driven by past countersuits and a desire to keep the pressure on. Sag also mentioned that these kinds of legal fights are not good for either company and could harm their relationships and the broader ecosystem.

Another analyst, Alvin Nguyen from Forrester Research, believes the court’s decision was pretty much what most expected. He explained that judges try to make their rulings stick and that Qualcomm is likely to stick with Arm’s technology since they’ve already invested heavily. However, Nguyen noted there’s an alternative—shifting to RISC-V, a different chip architecture. But moving to a new ecosystem like RISC-V would be a big change and could take time.

Nguyen also said that if legal issues continue to drag on and damage Qualcomm’s credibility or licensing deals, switching to RISC-V might become more appealing. For now, though, Qualcomm seems comfortable working with Arm’s designs, and the legal fight might just be a matter of patience and persistence.

This ongoing court case is more than just a legal battle; it could reshape relationships in the chip industry. Both companies have a lot riding on the outcome, and how they handle this dispute could influence the future of chip licensing and development worldwide.
