Apple invented a video headset back in 2006 and was granted a patent for it in September 2009. Since that time Apple has added a few inventions to keep their project evolving over time (one, two), with the most recent mention of a headset being noted in a patent application relating to hidden audio sensors. Over the weekend we covered a patent that Apple acquired from PrimeSense regarding an advanced headset to add to Apple's patent portfolio on head mounted displays. Today, the US Patent and Trademark Office officially published a knockout granted patent for a detailed head mounted head display that resembles the Oculus Rift which is the buzz of the gaming world at the moment. Apple's patent makes it clear that gaming is one of the main entertainment options for this device. It's also designed to be a personal display system so that you could enjoy full HD widescreen experiences on the go with your iPhone or at Home with your Apple TV. Without a doubt, it's the surprise granted patent of the year.
