I hate patent trolls. I don't know how anyone can be okay with making money by charging someone for their own work. It would be similar to a photographer that sold a photo to a bunch of clients. Then someone else copywrites the photo and makes the the original photographer pay royalties.
Hopefully the LOT Network will cut down on patent trolls. They have started out with some big names.
Now we just need a network for Photography Forum Trolls.
I'm an economist that works in IP. I think this is one of those situations where it should work in theory, but doesn't. I see nothing wrong with companies selling their IP rights to people who specialize in defending those rights. It just allows companies to commoditized their IP. i.e companies specialize for a reason, some companies are good at coming with IP, some companies are good at producing and marketing products that use the IP, and some companies are good at defending IP. So on the surface, there is no problem.
The real problem is that the patent office is a complete mess and the legal system for adjudicating this mess is even worse. In short, this allows trolls to hold up legitimate business with patents of questionable value. If the legal system got it's head out of it's ass, and started cracking down on people that tried to enforce questionable patents, then I think many of the problems would go away. Some patents are the result of legitimate and expensive R&D, and that type of thing needs/should be protected, even if it's done by a company that does not produce stuff. But sadly, the legitimate enforcement has been drowned out by the trolls.
