In U.S. Patent Application 20130339891 Apple Inc. claims "An interactive capability enables a user to dynamically adjust the content of an electronic map" as well as "Geospatial applications can be integrated with the map to provide information pertaining to the area displayed on the map, and to refine search results to those that are relevant to the area." Apple seeks to patent these ideas based on a number of claims.
The claims the patent application makes seem overly broad and applicable to many GIS capabilities; starting with "A method for displaying a map on a computing device, Comprising: storing information to be displayed on the map in a memory of the computing device, the stored information comprising a plurality of different layers of information, wherein each layer contains a respective type of information."
Surely there is prior art in many GIS systems that can be cited to refute this claim. Please do so.
