> The current state of the patent system is such that having been granted a patent legally supersedes in power the act of enabling technological advancement. That is to say that the power of the patent system has surpassed its social justification...

I'm not sure what your first sentence actually means, but there is not enough evidence to support the following sentence. I know it's a popular opinion around here, but really, it's because this place is an echo chamber when it comes to certain topics.

There are studies that show how NPEs have beneficial effects (see work by Michael Risch, Jay Kesan, Anne Layne-Farrar etc.), and others showing their harmful effects are not as bad as media makes it look. The GAO report on NPEs, for instance, found that they are no big problem, really.

Unfortunately, the data available is limited in a big way: there is no data at all on demand letters that trolls like Lodsys send. There's an act that would help track these things too (http://www.patentlyo.com/patent/2013/11/patent-reform-2013-d...), and that's the one I'm really looking forward to. That data would give a much clearer picture of the NPE situation.
