People will mention the problem with patents but I see another, perhaps bigger, problem: We do not have equal access to our judicial system in the United States. If you have money, you have the power to legally hold people with less over a barrel. That exploitable inequality is poison for a well functioning society. That is the problem that needs solving.
It's actually the opposite. These patents trolls are typically very small operations suing massive corporations. They aren't rich guys screwing the little guy. It's the little guy screwing whoever he can. These little guys have too much access to the legal system. That's why it's hard to clamp down on. Nobody wants to make it so only big guys can have access to the legal system.
#1: Big corporations can push small guys out of business by tying up their products in patent disputes.
#2: Patent trolls can bleed corporations big and small while producing nothing of value.
These problems are specific to the patent industry.
Are there similar problems in other areas of the law? If so, we may be able to identify and try to solve the larger problem. If not, we just need to focus on patent reform which is an easier problem.
