Imagine I'm a small software company, and I can't fight a patent troll, and I don't want to pay them or go bankrupt in legal costs. Can't I short-circuit that by just selling services elsewhere? Aren't there companies that just refuse to abide or negotiate with patent trolls, out of spite, what happens then? Can a patent troll shut down a company? At some point, wouldn't that make the news? What are the risks? What allows patent trolls to have legitimacy? I can understand that it's mostly a scam operation to extort money to those who want them to go away, but that can't always work. I've heard it's mostly a few courts in Texas or elsewhere. Isn't it possible to just not interact with the states where those patent trolls are?
