Another study by James E. Bessen: “The Private and Social Costs of Patent Trolls”
Patent trolls did cost society over $500 billion in the past 20 years. That’s not the money they sued for – that’s the money shareholders lost because of diving quotes because of a lawsuit. It’s money that was converted to nothing. No one, not even the trolls, had any advantage from it.
The study also shows that patent trolls only sue big companies. This is an indication of a weakness in the current patent system (the one after the “huge” reform).
