Re: "There is no inventive concept that provides something more than the abstract idea itself"
A patent is basically a law. It says that only company X, or people they approve, can do this thing. Anyone else has to pay a fine to company X, and stop.
Going to court to contest a patent claim is just not possible for most people, only the largest companies can afford the cost.
So I strongly disagree with your claim that the patent office shouldn't ensure that the patent is completely valid before granting it! They are making a law that normal people will not be able to fight. So they should treat that with the seriousness and great care which it deserves. They should ensure the patent is clear, and is genuinely a novel invention worthy of patent protection.
