Ask Patents is a question and answer site for people interested in improving and participating in the patent system. It's 100% free, no registration required.

The patent as described at http://www.google.com/patents/US20130318182 seems to describe a service already offered by Foursquare, and probably by Facebook and Google.

It claims to cover a server sending messages to mobile devices based on their geo-location.

So are FS/FB/etc. in breach? What's going on here?
