A computer implemented method and system enable users to create a social network providing access to other users. By providing access to such networks via a visual presentation (600), the system renders content available for access by other network members (620). Access is sometimes provided through propagation of metadata or other uniquely identifying indicia associated with the social network to all or at least certain other network members.

Why it's free to use
- Filed August 1, 2005 and granted November 26, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 1, 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.
