Last Thursday a number of very interesting patents surfaced at the US Patent and Trademark Office that Patently Apple amply covered. Yet a couple of minor yet interesting patent applications came to light that we thought shouldn't go unreported. The first one covers a new schematic mapping system for iOS devices, especially those with smaller displays such as the iPhone and iPod touch. The new schematic mapping technology will present maps that are very much like those that you'd see in a typical subway station. While the subway track itself may actually twist and turn from station to station, a typical subway map only represents the subway route as being in a straight line. Apple wants to simplify the mapping-out of routes for users by providing schematic routes to destinations. The second patent is an interesting one for business travels who would like their iPhone to carry a secondary mobile profile so that they could operate it in a foreign country without roaming charges.
