Qualcomm claims that Arm has been in breach of contract by misrepresenting the relationship between the two companies to Qualcomm’s customers, non-delivery of IP and misrepresenting its intentions as a design firm when it was preparing to sell proprietary ICs.
Qualcomm also claims that Arm interfered with its business by sending misleading communications to Qualcomm’s customers, suggesting Qualcomm was required to destroy custom CPUs developed by Nuvia. A proposition which is disputed.
Qualcomm is also alleging that Arm failed to license IP at reasonable prices.
In addition to court claims, Qualcomm has filed complaints alleging anti-competitive behaviour with regulators in the US, Europe, and Korea.
Qualcomm accuses Arm of curbing competition, 
restricting access to its technology and moving away from its traditional business model of open licensing to all on equal terms.
Arm is said to be developing a customisable CPU for servers, optimised for AI and HPC, with Meta as its first customer.
