What I don't understand is this. Obviously Apple has the right to stop paying royalties if they wish so. Should not they then stop using the components/technologies with Qualcomm IP in them? Do they feel entitled to the right to use Qualcomm IP regardless of whether they pay for it or not?
Apple has spent years doing this.
Think back to their complaints and lawsuits about Motorola's rates. I'm not sure Apple ever paid them. Too bad, it might've kept Moto a US company.
Apple did the same to Nokia, who then sued them in Delaware for a jury trial. Apple, not having the advantage of a home California jury, saw the light and settled out of court.
Mind you, it's considered normal to do this for a short while (using ETSI FRAND patents until a deal is made). But Apple's lawyers have turned it into a delay art form. After all, the worst case is they pay back royalties after denying funds to their patent holding competitors for years. The best case is, they find a sympathetic court which sets a much lower rate.
