On March 13, the US Patent & Trademark Office published two of Apple's patent applications pertaining to Cover Flow being used on an iPod classic and iPhone. The patent illustrates Apple’s calendar, address book, iPhoto and other applications being accessed on an iPod-like device in varying ways. Some methods include Apple’s touch screen technology on a classic iPod as well as using both a click wheel and/or touch pad. One of the 3D effects presented in the patent is rather cool. In light of the Microsoft patent that I presented yesterday, the timing of Apple’s updated Cover Flow patent for portables is more interesting than ever.
