New York Times has a nice article over-viewing various patents which bear Steve Job's name (there are 313 total though I'm not sure the Times has them all indicated). Many relate to iconic Apple products. But many are just design patents including the casing for desktop computers, packaging for the iPhone, and the design layout for the iPod.
So Apple's secret seems to be claiming a monopoly on things people find cute. What's next? Patents on adorable kitten videos?
