Title: Todd S. Glassey, Michael McNeil and Datum (Symmetricom)'s Joint Statement about IPR claimed in Glassey GeoSpatial Keying and Evidentiary Digital Testimony Models Received: May 29, 2003 From: Todd Glassey Please be advised that I (Todd S. Glassey), Michael McNeil and Datum (Symmetricom now) to varying degrees jointly hold rights to a patented set of technologies as specified in EuroPatent # EP 0 997 808. My and Mc Neil's rights therein are identified in a settlement agreement in addition to the patent and so the settlement agreement is a key piece in understanding the scope of licensable rights and their applicability. This includes, but is not limited to the Glassey GeoSpatial Keying ** and Evidentiary Digital Testimony Models and encompasses what is referred to as Phase One technologies in the settlement between Datum and us. All rights to Phase Two technologies rest with GMT. If there is an issue with this claim or you are interested in licensing this technology, contact me through my attorney, Dennis Kennelly Esq, at 650-853-1291. ** GeoSpatial keys are elements of location data from GPS or other sources, that are used a part of a cryptographic or evidentiary process within a digitally signed model. The use of geospatial keying allows for mechanically placed constraints to be setup on digital events so that they are particular to their physical location. One example of this would be the use in Cell Phones, but the reverse model is useful also as part of digital evidence statements based on a particular location. Todd S. Glassey IP owner.
