Jury Weighs Qualcomm Claims Against Arm in High-Stakes Chip Licensing Dispute

A major legal battle between semiconductor companies Qualcomm and Arm Holdings has reached a critical stage, with a US jury considering whether Arm breached contractual obligations and deliberately damaged Qualcomm’s business interests. The trial took place in federal court in Wilmington, Delaware, and represents the latest chapter in an increasingly strained relationship between the two companies. According to Reuters, the jury began deliberations on October 9, 2026, but did not reach a verdict that day. Deliberations are expected to resume on Tuesday, October 13. The dispute centres on allegations that Arm failed to provide essential software tools and technical support, violated pricing agreements and attempted to undermine Qualcomm’s negotiations with Meta Platforms. Both companies play important roles in the global semiconductor market, making the outcome significant for their commercial relationship and the wider technology industry.

Qualcomm alleges that Arm withheld software patches, testing tools and other technical resources that it was contractually required to provide. These resources are important because Qualcomm designs processors that rely on Arm’s computing architecture, which is widely used in smartphones and other electronic devices. Qualcomm argues that access to the necessary technical tools is essential for developing, testing and improving its chips. The company also claims that Arm violated an agreement intended to keep Qualcomm’s payments for certain processor designs within 10% of the lowest price offered to comparable customers. Qualcomm maintains that these alleged actions damaged its ability to compete and weakened the contractual relationship on which parts of its chip business depend. Arm disputes the allegations and has argued that Qualcomm has not demonstrated that it suffered actual harm.

Another major issue concerns Qualcomm’s proposed business dealings with Meta Platforms. Qualcomm alleges that Arm attempted to damage those discussions by leaking a letter to Bloomberg in 2024 that warned Qualcomm it was allegedly in breach of a key licensing agreement. Qualcomm argues that the disclosure could have harmed its commercial reputation and interfered with negotiations over a potential chip arrangement with Meta. Arm has challenged this interpretation and disputes that its actions caused the damage Qualcomm describes. The disagreement illustrates how confidential licensing disputes can extend beyond contractual obligations and affect negotiations with other major technology companies. The allegations remain contested, and the jury must assess the evidence presented by both sides before determining whether Arm violated its agreements or engaged in conduct that caused legally recognised harm.

The financial stakes are potentially substantial. Qualcomm has asked the court to allow it to stop paying royalties to Arm for up to five years if the alleged contractual breaches are established. Such a result could involve billions of dollars, although the final outcome would depend on the court’s interpretation of the licensing agreements and applicable law. Arm has argued that the proposed royalty penalty is unenforceable, while a separate proceeding is examining whether Arm has negotiated licensing terms with Qualcomm in good faith. The two companies have also been involved in an earlier legal dispute: in 2024, a jury did not find that Qualcomm had breached its licensing agreement with Arm. The current case therefore reflects a continuing deterioration in the relationship between the companies, particularly as Arm expands beyond its traditional business of licensing chip architecture and moves towards selling its own processors.

The outcome could influence how semiconductor companies negotiate licensing agreements and resolve disputes over access to essential technology. Qualcomm depends on Arm’s architecture for important parts of its processor business, while Arm benefits from licensing its designs to manufacturers across the industry. A prolonged conflict could create uncertainty around future licensing terms, product development and commercial partnerships. Investors and technology companies are therefore watching the proceedings closely, although no final conclusion should be drawn before the jury delivers its verdict and the court resolves any remaining legal questions. As deliberations continue, the case highlights the importance of clear contractual obligations and reliable access to technical resources in an industry where intellectual property and chip architecture underpin billions of dollars in business activity.
