It's obviously a ridiculous patent, so Apple can not possibly claim their competitors are piggy backing on their expensive research in this case.
Also, let's ride with the carbon fibre example. Is it really desirable that the world will have to wait for 50+ years until carbon fibre bicycles can be made accessible to the mainstream? Let's not forget that it is the public, proxied by the government, who grants patents, so obviously they should only grant patents if it benefits the public. This is not the case with patent trolling, because it only stiffles innovation (basically you need an army of lawyers to do anything interesting) and drives up prices.
