> I think the "victims" of the patent troll should seek their own remedy, by filing a cause of action including but not limited to tortious interference with business contracts and relationships (not to mention challenging the patent itself).

I don't think it's reasonable to expect all or even many of the victims to have the resources to devote to challenging this kind of thing, especially considering that MPHJ Technology is certainly not the only patent troll out there. Having a state AG take action makes it more of a fair fight.
