Apple seems to have big plans for sapphire with the latest clue coming from a freshly-published patent filing.
Published on Thursday by the US Patent and Trademark Office, a patent application dubbed simply "Attachment Techniques" describes ways to securely attach sapphire to an iPhone. Apple has already used sapphire for the lens cover on the iPhone 5 and the surface of the fingerprint sensor on the iPhone 5S. But the company wants to expand its use, at least as envisioned in the patent filing.
