It doesn't solve the problem of getting sued by a troll -- what patent are you going to use to counter-sue a business that doesn't have any business?

There is some good news though. Recent court cases (Alice, etc.) are really cramping the trolls' style. Intellectual Ventures and the like are backing away from the troll model because their crappy software patents are getting invalidated in court left and right.
