Hard to imagine that there won't be some sort of settlement (probably with a stack of money handed to ARM). ARM has no interest in slaughtering QCOM, which is one of their biggest customers.I think people are really missing on reading the last paragraph of the article.
If Arm is able to null and void the license because of the buyout, then Qcom would ether have to drop the goal, change it to fit into their own current ARM deal or expect to get hit again with another suit for royalties.
Even if Arm loses the first round they could hold up Qcom when their license runs out later.
