“Our last patent report for 2012 goes to a new patent application that was published by the US Patent office last week regarding an advanced ‘Active Stylus,'” Jack Purcher reports for Patently Apple.

“Apple’s engineers have been working on ‘reinventing’ the stylus for years now,” Purcher reports. “Even the idea that it was too easy to lose a stylus has been overcome with the advent of Apple’s work with encoded magnets that’s behind the iPad’s Smart Cover product.”

Purcher reports, “Today, the stylus is more like a crayon than a pen. Samsung’s Galaxy Note product with a stylus is a case in point. It just sucks as a pen. Apple’s latest invention introduces the ‘active stylus’ to overcome common stylus problems and names the iPhone and iPad by name as products that may be able to take advantage of the active stylus in the future.”
