To date, our most comprehensive report on Liquidmetal was posted back in April 2013. Today, Patently Apple is the first to discover four new yet painfully detailed patents in Europe on this subject matter. These extremely difficult reads were more about the science behind liquidmetal than products and yet at the heart of each we were able to find a few interesting trickles of new thinking of how Apple could translate this material into elements related to future products. In fact, one of the four patents delves into liquid metal as it relates to plastics and more particularly, to plastic injection molding. It makes you wonder if there's a connection between Apple's new iPhone 5c and Apple's work with liquidmetal.
