Abstract From the Canadian patent

An improved system and method are disclosed for peer-to-peer communications. In one example, the method includes retrieving a profile and a routing table from an access server by a first endpoint during an authentication process. The profile identifies at least a second endpoint as an endpoint with which the first endpoint has permission to communicate. The routing table contains address information needed for the first endpoint to communicate directly with the second endpoint. The first endpoint sends a notification message directly to the second endpoint using the address information to inform the second endpoint that the first endpoint is online.

Why it's free to use

  • Filed March 29, 2005 and granted August 21, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 29, 2025.
  • Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
