The US Patent and Trademark Office (USPTO) has given Apple a total of 13 patents today, covering a wide range of topics from the design of the Thunderbolt Display to the (at the time) revolutionary interface for managing lists in iOS. The latter is an important patent that may be leveraged in future litigation, as most other smartphone competitors have copied it fairly closely in their own implementations. Apple was also given a patent for its now-discontinued Bluetooth headset.
