Abstract

A method and apparatus that allows for the distribution of electronic licenses is disclosed. The method and apparatus may be used in a network or non-network environment to facilitate product licensing and upgrades. Further, the method and apparatus accommodate the use of compact disc read-only media (CD ROM) product distribution. The method and apparatus provide the ability to disable electronically distributed material. Further, the method and apparatus provide the ability to license use of the material by some entity in the distribution chain. The method and apparatus protect multiple electronic licenses by disabling the license such that an enabler key is necessary to enable a license for use. The method and apparatus reduce the cost of electronic distribution by providing the ability to distribute multiple products, product versions, and licenses that are unusable prior to the execution of an enablement procedure. The method and apparatus provide the ability to take advantage of the benefits of CD ROM, or any other (high capacity or otherwise), distribution media. For example, a generic distribution CD-ROM can be manufactured for a wider enduser base that contains multiple product and licensing options. An enduser can contact a fulfillment entity to purchase products contained on the distribution CD-ROM. In return, the enduser receives enabling information that can be used with an enablement procedure operating on the consumer'"'"'s computer system to enable the purchased product(s). The method and apparatus can be used with a network server product that limits connection access electronically using connection-stratified server connection licenses or connection-stratified server executable files.

Claims

1. A method of electronic licensing distribution comprising the steps of:

creating a plurality of electronic license sets, each of said electronic license sets associated with one of said plurality of products, each electronic license set comprised of a plurality of electronic license;

disabling said plurality of electronic licenses in said plurality of electronic license sets;

transferring electronic copies of a plurality of products to a final distribution medium;

transferring electronic copies of said plurality of electronic license sets to said final distribution medium;

distributing said final distribution medium to an enduser.

2. The method of claim 1 further including the steps of:

selecting by said enduser one of said plurality of products;

selecting by said enduser one of said plurality of electronic licenses;

obtaining by said enduser an enabler key from a fulfillment agent based on said one of said plurality of products and said one of said plurality of electronic license;

executing in a computer system an enablement process to enable said one of said plurality of electronic licenses.

3. The method of claim 2 further including the step of installing said one of said plurality of electronic licenses in said computer system.

4. The method of claim 2 wherein said enablement process comprises the steps of:

extracting, by said enablement process executing in a computer system, an offset, said offset representing a location of a value within an encrypted portion of said one of said plurality of electronic licenses;

decrypting said value at said offset using said offset as a decryption key.
