US patent application 13/501,392, filed on Oct 12, 2010 and published on Sep 27, 2012.
It appears that the main claim is simply to be able to refer to a latitude/longitude point through a unique identifier, which in turn is persisted in a database of entities for later fetching via “computing devices”.
I believe that this covers any technology which stores locations with a primary key in a database. This is incredibly common and would likely apply to many products like Google Places, Yelp, or Foursquare.
It really boggles my mind that somebody would file a patent for this (as I can think of so many existing products that operate in this manner) and was hoping to see what you guys thought in terms of potential prior art.
