Abstract

A software rental system that offers commercial software products to client systems on the rental basis over a communication network is disclosed, wherein the commercial software product is installed on the client terminal in the client system. Every software product installed on the client terminal has a first license manager built thereinto. When a software component of the software product that resides on the client terminal is activated and terminated by the user, the first license manger is enabled to intercept the start time and end time, and send this time information, over the communication network, to a second license manager within the appropriate server system that has licensed the user to use the software product. On the server system, the start time and end time information received from the first license manager is analyzed, and the usage fee to be charged to the user is calculated. A firewall is provided between the client systems and the server systems so that only signals that conform to a particular communication protocol can be passed through the firewall. The communications between the client systems and the server systems over the communication network can occur without having to care about the communication paths along which the communications travel and as if the first license manager in the client systems and the second license manager in the server systems reside on the same LAN.
