I'm not sure which is more corrupt, inept, incompetent, and useless -- the USPTO or the USgov. It's easy to see the real point of the patent system when you read that the patent "examiners" have to fulfill a monthly quota for granted patents, and also that the USPTO charges what I would consider a rather hefty fee to "re-examine" a patent they never should have granted in the first place.

Unfortunately, like everything politicians touch, it's been twisted, corrupted, and mangled into something that barely resembles its former self.
