US Patent 6859792 Product suite licensing method

A license management method specifies a predetermined number of assigned units for each of a plurality of individually selectable programs in a product suite. A discrete node running total equals the assigned units of the highest assigned units program running on each node. Each node can run additional programs where the assigned units of the additional programs are equal to or less than the node running total without changing the node running total. Termination of the highest assigned units program on a node causes the difference between the assigned units of the terminated program and the next highest assigned units of a program running by the node to be re-added to the available units.
