I`m certainly not ``techie`` enough to provide an adequate response re: what ARM could try and pull off. My understanding is that our patented technology is fundamental in all ``fast`` micro-processors, so with my very limited knowledge and taking this claim as truth, I don`t see how they can escape.
I actually think it would be in ARM`s best interest to seek settlement under the best terms they can. If for nothing else to reduce the concerns of their customers.
My thoughts on the possibility of royalties has to do with the potentially huge amount they have to pay, whether based on pre-trial settlement or court judgment. If they can`t come up with the cash, that leaves them with other alternatives; e.g., installment payments, royalties, offering ARM stock or stock options, first born male child, etc. (or some combo).
I don`t KNOW, but I`d think a reasonably fat up-front licensing fee plus ongoing royalties is commonplace (the up-front fee intended to compensate for past infringement, royalties to cover future infringement until infringement ceases).
Hope this helps. All JMHO.
