On June 13, 2013, the US Patent & Trademark Office published a patent application from Apple that reveals an all-new kind of tablet cover. The patent filing is deadly focused on the make-up and process in creating the cover using various materials with non-radio portions so as not to interfere with the tablet's various radios. Considering that Apple's original Smart Cover was introduced in early 2011 and that this new filing was only filed in December 2012, it's pretty clear that Ive's Industrial Design Team have something completely new in mind. Could it be a new iBooks centric design? Only time will tell.
