Apple's done plenty of patent trolling of their own. Remember the rounded rectangle fiasco?
That's all beside the point. If patents are reformed so that only big corporations like Apple can use them to attack their competitors, what really will have changed? Sure, the swarm of bees (NPEs) might be gone but we'll still have to deal with the angry bear. And what of small inventors without the means to capitalize on their innovations? What will protect them if their legal power to enforce licensing deals is removed?
