Patent ID: 7418421

Claim:
A computer-implemented method of dynamically negotiating a transaction comprising: determining a plurality of potential transactions according to transaction parameters stored within at least one transaction parameter data store, said transaction parameters being associated with two or more potential transaction participants, and, for each potential transaction, assigning to each of said participants a separate transaction score such that a plurality of scores, one for each of said participants, is associated with each potential transaction; ranking each potential transaction based on a mutual benefit of each potential transaction to all transaction participants and assigning a higher rank to a particular potential transaction that has a higher mutual benefit than that for another potential transaction, wherein said mutual benefit is computed taking into consideration of a total score of all participants and a participant score differential for each potential transaction, wherein each participant score differential measures a difference between transaction scores respectively assigned to each participant for a corresponding potential transaction, wherein a smaller participant score differential means a higher mutual benefit; sequentially presenting to each of said participants each potential transaction according to decreasing rank until all transaction participants agree to a presented potential transaction or until no potential transactions remain to be presented; determining whether an acceptable potential transaction more favorable to the at least one rejecting transaction participant can be generated by another participant altering at least one associated transaction parameter; and notifying said another participant that an acceptable potential transaction can be generated if said participant modifies at least one associated transaction parameter.
