"The patented coupon system is differentiated from other systems by allowing the coupon creator/author (retailer, manufacture or service provider) to determine, who, when and how the coupon is delivered to the end user. The coupon can be triggered to life by any number of conditions such as time/date, geo position, event, etc.
This system is particularly beneficial to the retail sector allowing a retailer to take back control of who, when and how an offer is issued as well as having full control of the discount offered to their customers. "

This could be absolutely massive difficult to put a potential revenue number on it but my guess would be a percentage of every Advertisement that incorporates this into their campaign maybe every coupon redeemed of sale made. Sounds like the kind of closed loop information retailers would pay big bucks for    . Market has missed this if you ask me
