Filed on October 26th last year and approved today, a design patent at the USPTO grants Google the rights to the ornamental design of its newly unveiled Project Glass augmented reality glasses. Patent D659,741 lays claim to the whole appearance of the whole "wearable display device," however looking at the images presented, the actual glass element that serves as the display isn't covered by the patent. It's represented by hashed lines, which serve to only illustrate design patents — what Google has the rights over is the frame and overall construction of the device. Engadget was first to spot the new information on the US Patent and Trademark Office website, while also noting a pair of other design patents, referring to some alternate frame ideas Google has been mulling over. As Sergey Brin said, Project Glass is still at the early prototype stage and we could still see the device's appearance change — so frameless or even glasses-free goggles aren't completely out of the question.
