Why is this in the PC section? It has nothing related to PC gaming at all. ConsoleSpot running out of ideas for PC articles as usual?
@-Unreal- They don't make news they just report it. Consoles are just more popular right now, get over it.
Nintendo, Sony, Microsoft, and Sega patented these game systems and controllers, but stopped short of releasing them.

The original Nintendo Entertainment System controller is as iconic as it is uncomfortable. The hard plastic rectangle certainly got the job done, but it wasn't exactly easy on the hands. Nintendo addressed this in the fall of 1993 with a more rounded controller that came packed in with the top-loading redesign of the NES hardware, but the company also received a patent for a different NES controller design that same year. The alternative redesign of the NES pad closely resembles the original rectangular pad, but with one key difference: there are two semi-cylindrical extensions on the back of the pad that would seem to curve along with players' fingers, giving the pad a bit more bulk for larger hands. Although such protrusions weren't often used at the time, they've become a staple of console pads in recent years, with Sony, Microsoft, and Nintendo all adding them to their standard gamepads.
