Arm has escalated its feud with Qualcomm by canceling the architecture license that allowed Qualcomm to use its intellectual property for chip design, following a lawsuit filed against its former partner in 2022. The British semiconductor company sent Qualcomm a 60-day notice of cancellation, potentially impacting both companies’ finances and operations if an agreement is not reached. Arm accused Qualcomm of not obtaining necessary permits for the acquisition of Nuvia, a licensee, leading to the termination of licenses. Qualcomm could face a significant revenue loss if they do not resolve the issue within 60 days, with the US company believing Arm’s actions are aimed at increasing royalties. Qualcomm refuted the claims, accusing Arm of disrupting the legal process with baseless threats. Arm defended its actions as necessary to protect its ecosystem, expressing confidence in the upcoming trial. The story was updated on October 23, 2024, to include Arm’s statement.
