Patently Apple has discovered a new patent application in Europe that's quite fascinating. Many assume that Apple is using Corning's Gorilla glass for the iPhone 5 but Apple's latest patent puts that into question to a certain degree. Especially in light of Apple's use of thinner In-Cell glass, Apple may have used a new process for strengthening their thinner glass. The patent doesn't confirm if the patent pending process was used in the manufacture of the current iPhone 5 or is one destined for future iDevices. But it's abundantly clear that Apple has a new process for strengthening thin glass that involves the use of a very sophisticated "Glass Ion Exchange Bath" system. While those who love Apple products can feel the magic of using their iDevices, most will never know the depth and lengths that Apple will go to get a product just right. Apple's latest patent is proof of Apple's dedication to excellence.
