If you read my article, you'll see that's not what the study finds. They estimate that less than 10 percent of the wealth lost by defendants goes to patent trolls. The rest is destroyed.
There is quite another type, alive and well in our political and legal system, that have no problem stealing or ruining thousands for a few dollars gain for themselves. I well and truly wish these folks hadn't been born.
I feel as soon as humanity grows out of the stage where this kind of behavior is tolerated, we'll be well on our way to the utopia that most of us hope for. Once you nip this impulse in the bud, it won't matter if the systems are socialist, capitalist or whatever, they'll probably work just dandy. This is why we can't have nice things.
If you dig into the dataset you can see that patent trolling drastically increased after 2005, given the stock market trends over that period it's not surprising that companies would lose a lot of value after a litigation event in a market defined by lack of confidence.
Also, as the case progresses the market will price back in the EV of the litigation, how do they account for that? A lawsuit is big news, a technical maneuver in court that absolves a lot of liability may not because of the complexities involved.
