I am sure this group is aware of the TCS patent. Pretty irksome given that PIDF, LO, PIDF-LO, SUPL and so forth are all open, freely available standards. To use an open standard and then patent an idea about how to use an open standard. Give me a break. In all my years in the geospatial industry, I have never seen anything like this. Even more irksome given that the LO is totally generic and application neutral. Also, in the GIS/geotagging community there is I suspect significant prior art.
The format of the Presence Information Data Format--Location Object (PIDF-LO) as defined by the Internet Engineering Task Force (IETF) is extended or modified to accommodate, within the standard PIDF-LO format, an association of geospatial location to virtual content on the Internet. A filename of virtual content is associated with geospatial location information (either a specific location, zone, or direction). The filename is inserted into a <presence . . . > section of a Presence Information Data Format-Location Object (PIDF-LO) compliant document as defined by the Internet Engineering Task Force (IETF). In this way, geospatial location information is associated with Internet based virtual content using a standard PIDF-LO format.
