There is a lot of hate for the patent system because it is obviously broken. First, as noted in the Ars Technica article, you don't actually have to show that your invention works to get a patent. Second, you don't actually have to be the one producing your invention and making it available to those who can benefit from it to claim patent rights. Third, independent invention doesn't defend you against a patent lawsuit. And fourth, the patent office does not even try to apply the actual standards required for an invention to be patentable: that it must be original, non-obvious, and an enhancement over prior art.

If those things were fixed, I think there would be a lot less hate for the patent system. Also, of course, this particular patent lawsuit would never have been possible.
