Today the U.S. Patent and Trademark Office officially granted Apple a patent that relates to redesigns of Apple Watch and MacBook (primarily) wherein their current metal casing would be replaced with one mainly made of glass ("plastic, glass, carbon fiber, ceramic, or other materials").

The patent also illustrates how this invention could apply to other devices such as an iPhone and Apple Pencil.
