On May 16, 2013, the US Patent & Trademark Office published a patent application from Apple that reveals their ongoing work with their future "Shopping App." Apple first revealed an extensive patent filing for NFC as it related to "Shopping" back in 2010 as a companion app to their future iWallet. Just like Apple's Passbook keeps gift cards, coupons, tickets and passes into an organized app, Apple's iWallet is likely to contain another round of things that relate to their financial app and the "Shopping" feature is just one. Last week's update to the Shopping app focused on methods of setting payment option preferences and more. Today's patent application adds at least five major aspects to the "Shopping" apps patent claims. The base of the patent doesn't change much if any. It's all about securing key aspects of the invention that Apple wants to protect, just in case they have to go court over it in the future.
