Qualcomm Accuses Arm of Anticompetitive Practices in Global Regulatory Complaints
Qualcomm has filed confidential complaints with antitrust regulators in the US, Europe, and South Korea, accusing Arm Holdings of leveraging its dominance to suppress competition in chip design. The filings, submitted to the US FTC European Commission and Korea Fair Trade Commission, alleged that Arm is restricting access to critical technologies and altering licensing terms to favor its own chip ventures, Bloomberg reported. Arm swiftly denied the claims, claimining that this is a distraction from a broader commercial dispute. "Arm remains focused on enhancing innovation, promoting competition, and respecting contractual rights and obligations," a company spokesperson told Tom's Hardware. "Any allegation of anti-competitive conduct is nothing more than a desperate attempt by Qualcomm to detract from the merits and expand the parties' ongoing commercial dispute for its own competitive benefit. Arm is confident that it will ultimately prevail in this dispute."
Qualcomm's filings argue that Arm is abandoning its longstanding open licensing model, which enabled a global ecosystem of chipmakers and software developers. Instead, the company claims Arm is prioritizing its compute subsystems (CSS)—pre-packaged chip designs for client devices and data centers—by limiting rivals' ability to license core technologies. Qualcomm also alleges Arm is withholding IP and violating agreements, particularly for clients developing custom silicon based on CSS designs. The complaints follow a recent legal victory for Qualcomm in a Delaware court, where a judge ruled the company did not breach licensing deals by acquiring chip startup Nuvia and using its IP in Snapdragon X processors for PCs. Arm, which plans to appeal the decision, insists Qualcomm's regulatory push is an escalation of the same dispute. According to Bloomberg's sources, Qualcomm's EU complaint—filed before the December court ruling—warned that Arm's post-2024 licensing changes would force chipmakers to obtain direct architecture licenses to use CSS designs, which could marginalize competitors. Arm confirmed it is preparing a formal response to the EU filing, while Qualcomm has reportedly engaged regulators in Washington and Seoul on similar concerns.
