RE: Poynt and Foursquare are growing Big: try this one on for a size!
"Foursquare Labs, Inc., the company behind the popular check-in service, has been slapped with its first patent infringement lawsuit by a company called Mobile Commerce Framework."
"According to MCF, Foursquare infringes its patent by creating and distributing mobile apps that can be used by people to obtain information and offers from merchants by searching, based on their physical location and merchant type."
"Mobile Commerce Framework is asking for monetary damages and that “Foursquare be directed to withdraw from distribution all infringing products, and that all infringing products or materials be impounded or destroyed”."
The issued MCF patent that is being referred to is here: https://www.google.com/patents/US7693752 . Their earliest priority date is 2004. Poynt's base IP was filed earlier than that -> https://www.stockhouse.com/Bullboards/MessageDetailThread.aspx?sv=2&p=0&m=29267140&r=0&s=PYN&t=LIST
