It's interesting that you suggest the little guys need patent trolling to get ahead, as from my own reseearch it seems that the currennt patent system benefits the larger companies far more and that those larger firms are perhaps far worse patent trolls as they have the money to back it up.
One need only look at the recent problems with King and how it went after the trademark Candy, to push Candy Swipe out of the market (despite it being a much older game with more of a market pedigree) and then attempted to trademark Saga and block The Banner Saga from using the name.
Similarly Samsung and Apple go at each other whenever they get a chance, buying companies full of patents in order to use them against one another.
And the little guys don't even get protected by it. Look at the way Zynga copies almost all of its big name games from smaller developers. Those developers never won any money or received compensation.
That said, I can see the benefit in taking time to collate data from several studies. If a change is going to be made to patent law, it shouldn't be rushed.
