Some have dissed the iPhone 7 for being too similar to the 6S. But a new patent shows that Apple may have an interesting direction for a future iPhone.

The US Patent and Trademark Office granted a patent to Apple on Tuesday for a bendable or foldable iPhone, according to Patently Apple, which was first to report the news. It looks as though such a design has been on Apple's mind for a while. The company applied in 2014 for the patent titled "Electronic devices with carbon nanotube printed circuits," according to the USPTO.

Although a folding iPhone sounds like it could be fun, there's no telling when or if this idea will come to fruition. Samsung, for instance, in April of this year was granted a patent for contact lens augmented-reality displays, but that technology seems awhile away.

Apple did not immediately respond to a request for comment.
