Apple has been granted patent rights for a new process using high temperatures to shape and mold a curved glass casing, similar to the one currently on newer Samsung devcies, as opposed to the very flat screen found on the iPhone 5.
This exact patent doesn't have a huge influence on Apple's actual production line, and definitely doesn't portend anything as interesting as a new iPhone design. But it does show that Apple has been researching how to make this kind of curved glass for a long time, and that the company's very interested in finding more and easier ways to make its world-famous device components.
The process also covers glass of all shapes and sizes, so while the images included with the patent (as seen above) hint that it would be used to make new iPhones and other portable devices, the documents also say that the glass could be shaped for larger devices, including "displays, monitors and televisions." Apple's work on processes like this is an investment not just in determining how to create today's devices, but a look ahead to what it might create in the future as well.
