Google’s patent application for “MULTIPLE PARTY ON-LINE TRANSACTION” describes a method for making a purchase involving multiple individuals.  For example, you and your boss, where you need a product for work and your boss needs to make or approve the actual purchase.  

The summary describes the invention in this way.

“One method includes the actions of receiving a role associated with one or more parties involved with a purchase transaction, receiving a routing rule associated with the purchase transaction, the routing rule defining how the purchase transaction is routed among the one or more parties, and processing the purchase transaction based on the role of each party and the routing rule.”

The patent application’s first Claim reflects this.  Are there no other systems doing this today?  Perhaps a B2B procurement system?
