While Microsoft's Surface tablets may not be exactly clicking with consumers, some of its design elements have won the blessing of the U.S. Patent and Trademark Office.
The USPTO granted a trio of patents today for the touch/type cover keyboard design on Redmond's tablet, including its "ornamental design for an electronic tablet with input device coupling," as Microsoft described the construct in its patent application abstracts. Apparently thinking it was onto something big, Microsoft applied for patents covering its tablet's keyboard design last May, roughly a month before the mystery event that turned out to be the device's unveiling.
