The Apple iPod Shuffle Design Patent
Though usually more advanced and complex designs are popular, this iPod shuffle seems to suggest otherwise. This design patent protects the image of the iPod shuffle - a simplistically easy-to-use MP3 player. It is designed compact with only 4 buttons and no screen (a relatively innovative idea to the MP3 player market). It simply shuffles through your playlist. Thus, this patent protects its popularly simple look and feel.
