You know those augmented reality glasses being developed by Google that everyone is going crazy over? Well, Google was just granted three patents covering the technology behind them. Google isn't the only one working on the technology, but they are the only ones to have gained patents for it which should give them a leg up on the competition.

The patent numbers, in case you should want to look them up, are D659,739, D659,740 and D659,741. They are for a "wearable display device" and a "wearable display device frame." The device first made an appearance in an online video last month and made its rounds around the internet, including here on TweakTown.

The patents were filed October 26, 2011, which shows that the technology has been development for some time. What's more is that they are being tested by Google executives which shows the support for the project is coming from the top. With that support, it is all the more likely that these will eventually hit store shelves.
