I'm not sure how Apple hasn't been rewarded for their efforts. What more, exactly, do they need ... We've had years of Apple sitting on an epic pile of money
What you are doing is looking at the success story and saying 'they already made 100x on their investment that should be enough!' but neglecting to consider the chance of failure. We don't have patents so that Apple can make 150x times their investment instead of 100x, we have them so that companies looking at 150:1 odds instead of 100:1 will try to make those big changes in the first place.
Do they also get to make spurious patent claims left and right now
Absolutely Apple should continue to get advantages over non-innovating competitors even though Apple already has gobs of money.
