Patent law is nice when it ensures that innovators are compensated for their work, but Apple has clearly been compensated. Perhaps it could benefit from an addendum -- not enforceable when you're already making a ton of money off your innovation.
Why would anyone do the work to innovate if they can't make a ton of money with patent protection? Who's to say what a "ton" of money is? How much did it the initial work cost? Worrying about compensation isn't a good metric for patent validity.
>Why would anyone do the work to innovate..
This is a very weak defense of the patent system. Innovation happened before patents existed, and would continue to exist without them.
