In an article I found, one magician is suing another magician for copying the original magician’s trick. This brings up an interesting question, how far should copyright extend? Should actions be copyrighted as well, or just objects? The magician in question has fled the country and is doing a successful job of evading charges by simple having his whereabouts be unknown. So, how far should copyright extend? How can a law protect an action? To what extend should this be done? For example, if a coach on a sports team comes up with a particular play or technique, should it be copyrighted and not allowed to be passed on?
