Open the CIPO recordAbstract From the Canadian patent
A directory service has a number of databases and a processing system with a number of processors. A first processor receives requests and passes them to one of a number of other processors to access one of the databases. The service has a firewall and a monitor outside the firewall for randomly generating names to access the database. A configuration manager communicates with applications in the database and processors and with a directory to cause applications to reconfigure in response to certain events.

Why it's free to use
- Filed April 14, 1997 and granted March 5, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 14, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 14, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
