Patently Apple was the first to discuss the possibility of Apple using sapphire crystal glass for future devices back in March 2013 before it was on anyone's radar screen. Since that time we've covered all of Apple's major patents concerning the use of Sapphire for displays in future iPhones. There was one covering a fusion process for adding a sapphire laminate layer to a future iPhone. Then there was the killer patent covering a futuristic sapphire flexible transparent display in December 2013 quickly followed by one covering techniques for using sapphire on iDevice displays in January. Today the news gets better as equipment for producing the sapphire materials has arrived at Apple's Arizona plant.
