Suppose you are in a cafe and of course you have a laptop with you. All of the sudden, a little box pops up and says “Brian Groth is nearby and you have a meeting next week. Click here to see more details.”
Microsoft and I recently got patent number 455041200 that explains how this works. It is titled “Automatic Detection and Notification of Proximity of Persons of Interest”
It took a few years to get through the USPO and I am not able to find it via the USPO web site, but it can be found via Google’s Patent Search site.
Thanks to Shish letting me know that it was finally approved. Good luck on your patent Shish!
