Microsoft has finally picked up a patent for their Microsoft Touch Cover, thanks to the good people over at the US Patent and Trademark Office who were the ones who granted this particular patent. If one were to be more specific, it would boil down to Microsoft's design of the Touch Cover itself that picked up this particular patent, alongside the design that makes up the magnetic base for the cover that enables it to quickly and tightly hook up the Surface tablet to itself.
