ARM's case is that a uarch is necessarily tied to its ISA and that their license isn't transferrable because the contract plainly says so. If Qualcomm can show up and say "here's our uarch running a different ISA", it disproves that point and at most leaves dispute about some patents where Qualcomm can probably get a quick settlement for far less than the royalties would cost them. The whole point of Znew is to transform RISC-V into something so similar to ARM64 that they can swap out the decoder and be good to go.
