Late yesterday Patently Apple discovered a unique patent application from Apple that was published in Europe. The patent contains a feast of cool new ideas floating around Cupertino's R&D labs. Apple's many inventions are illustrated on both MacBooks and a possible future iPen. Apple discusses varying flex display designs and a new illumination process that is very cool. Some of the features described in this latest patent filing could easily be applied to future wearable devices from Apple. All-in-all Apple's European patent application was a lot of fun to explore and I think that you'll really enjoy our report covering its many highlights.
