VeriSign, Inc., on behalf of itself and its Related Entities, irrevocably covenants that, subject solely to the conditions described below, it will not assert any of its U.S. or foreign patents, having claims necessary for the implementation of the OpenID Specifications listed below, against that portion of a product that implements the covered specifications listed below (OpenID 1.1 Implementation).
Conditions: this covenant shall not apply with respect to:

- for implementations that are not required by the listed Specifications or can be implemented by an alternative design not covered by VeriSign's patents and still be in conformance with the Specifications.
This statement is not an assurance either:
- that any of VeriSign's issued patents cover an OpenID 1.1 Implementation or are enforceable; or
- that an OpenID 1.1 Implementation would not infringe patents or other intellectual property rights of any third party.
