occasional gem, but often you'll read scores of pages only to discover that the so-called invention has already been put to use by others. In this instance, Apple has successfully patented the idea of using NFC to establish a master/slave relationship between two smartphones, as a prelude to making a fully-fledged WiFi connection that allows the sharing of contact details or more complicated sequences of actions. Now, this is a smart idea, especially since the patent specifically talks about retail applications (shown above), but is the end result so wildly different to Android Beam or even Bump? Even Fujitsu came up with a similar concept for using NFC to trigger location-relevant workflows. Either there's some significant overlap here, or we've spent too long playing reed instruments.
