Patent trolls aren't the problem. The problem is that it's a profitable business model to have an idea, patent it, and then sit on it waiting for somebody to accidentally recreate it.

The reason this is a profitable business model is because too many obvious patents are granted. If granted patents were truly non-obvious, the likelihood of accidental infringement should be exceedingly low.

Patent trolls are merely a symptom of this issue. Hurting trolls does little to attack the wider problem.
