Yes, agreed, which is why I think it is hypocritical of King to file for the patent, and for the patent office to see it as a reasonable patent to approve.
Quote: "I don't think it matters who made the first wheel, just who filed the first patent."
Nice example
The wheel was patented in 2001 by an Australian guy. However, he did it to ridicule the system and won't be suing anyone who ever made a wheel.
The best patent ever in my opinion is the patent trolling patent, That is, the idea that you buy patents simply in order to sue people. Therefore, if you are a patent troll, you can be sued by the owner of the patent trolling patent (Halliburton Energy Services)!
How silly can it get though? Apple have a patent for round corners on electronic devices. If you have a tablet or phone with rounded corners that isn't an Apple device, it's infringing this patent. This is absurd, as the original reason for rounding corners was because it was cheaper to manufacture ("square" looking cars didn't appear until the 80s for this very reason). Did the patent office never see a ZX Spectrum, Nintendo 64, Gameboy etc?
