The US Patent and Trademark Office (USPTO) has issued some 52 patents to Apple in the course of the last seven days, including 22 awarded on January 10th, an additional eight awarded on the 12th and a further 22 patents today. One of the most interesting is a "smart garment" patent that may foretell an expansion of the Nike+iPod line, along with a patent that hints at a future Apple TV. Others of note include a longer "trackbar" for notebooks with secondary zones, and what may end up being another Apple attempt at a headset for the iPhone.
