Jury Finds Arm Breached Qualcomm Licensing Agreement in Major Chip Industry Dispute

A federal jury in Delaware has ruled in favour of Qualcomm on two important claims in its legal dispute with British chip technology company Arm Holdings. The verdict, delivered on October 13, 2026, found that Arm breached its Architectural License Agreement with Qualcomm and intentionally interfered with Qualcomm’s business relationship with Meta Platforms. The jury awarded Qualcomm nominal damages totalling just $2, or $1 for each successful claim. Although the monetary award was small, the decision represents a significant development in the dispute between the two semiconductor companies. The case centres on allegations that Arm failed to honour contractual obligations and took actions that damaged Qualcomm’s commercial interests. Both companies claimed partial victories because the jury also rejected several other allegations brought by Qualcomm.

Qualcomm had accused Arm of withholding software patches and technical tools that it said were required under their licensing agreement. These resources are important because Qualcomm relies on Arm’s computing architecture to develop processors used in smartphones, personal computers and other electronic devices. Qualcomm argued that Arm’s actions undermined its ability to develop and commercialise products under the agreement. Arm, however, disputed the allegations and argued that Qualcomm had not demonstrated meaningful financial harm. The jury ultimately found that Arm had breached the overarching licensing agreement, but it did not accept every claim presented during the trial. The mixed verdict reflects the complexity of the contractual relationship between the two companies and the competing interpretations of their commercial obligations.

Another major issue involved Qualcomm’s business relationship with Meta Platforms, the parent company of Facebook, Instagram and WhatsApp. Qualcomm alleged that Arm intentionally interfered with its commercial negotiations with Meta by leaking a letter to Bloomberg News in 2024. The letter reportedly notified Qualcomm that Arm believed the chipmaker was in breach of a key licensing agreement. Qualcomm argued that the disclosure created uncertainty during negotiations over a potential chip deal with Meta. Arm disputed the claim that its conduct caused financial damage, arguing that changes in Meta’s product strategy affected the negotiations. The jury nevertheless found that Arm had intentionally interfered with Qualcomm’s business relationship, although the nominal damages awarded did not establish a substantial financial recovery for Qualcomm.

The dispute has broader implications because Qualcomm depends heavily on Arm’s processor architecture, while Arm earns revenue by licensing its technology to companies that design their own chips. Their relationship has become increasingly strained as Arm expands its ambitions beyond licensing intellectual property and moves further into developing and selling its own semiconductor products. Qualcomm has argued that contractual protections should limit how Arm changes licensing terms and supplies essential technical resources. Arm, meanwhile, has challenged Qualcomm’s interpretation of agreements that were negotiated years ago under different market conditions. Qualcomm’s licence for Arm’s computing architecture runs until 2033, making the outcome of the dispute important for future product development and negotiations over access to newer versions of the technology.

Despite the verdict, several important legal questions remain unresolved. Qualcomm has argued that a contractual provision could allow it to stop paying royalties to Arm for up to five years following a qualifying breach, potentially involving billions of dollars. However, the jury’s $2 award does not itself establish that Qualcomm can suspend those payments. US District Judge Maryellen Noreika must address the relevant contractual and legal questions, including the enforceability of the proposed royalty remedy and issues concerning future licensing negotiations. Both companies may also pursue further legal challenges depending on the court’s decisions. The case therefore remains financially significant despite the small damages award. Its eventual outcome could influence the companies’ negotiations, their future commercial relationship and the wider semiconductor industry’s approach to technology licensing.
