Re: The law is clear
He has a patent and apparently he was the developer (of what he believed is) a valid patent. In my book he is not a patent troll.
In that context *we* cannot judge whether the patent is valid or not - that's his decision to enforce his patent through the courts and the court's job to decide whether it's valid or not. No level of jaw ache by people here will make any difference unless they are called as expert witnesses for the case.
