Having just listened to the "When Patents Attack!" podcast today (http://www.npr.org/blogs/money/2011/07/26/138576167/when-pat...), I question how this addresses what I saw as the fundamental challenge with patent trolls -- shell corporations. These companies are spawned as needed to sue the alleged patent infringers. Since the shell companies are just a bunch of lawyers and the ownership of a patent, there's little in the way of assets to counter sue for (i.e. there's not much for the suing entity to lose). I don't think these guys will be swayed by a moral or ethical argument either. And since these shell companies don't employ coders, well, I don't expect it will impact who coders decide to work for.
