Nintendo trademarks and copyrights everything in their games. Copyright is much more insidious, because it pretty much never runs out. You can't just patent a patent of a patent. It's not that easy. You need to extend the usefulness of the original patent with something new. And guess what? Anyone else can do that to your patent as well. But you can trademark an effect. Then, no matter what the code, no one can duplicate it. Apple haven't done that.
