Abstract From the Canadian patent

A system for providing personal communication services (PCS) is described, wherein a subscriber can tailor the telephone service to provide communication mobility and incoming call management. Calls to a personal number assigned to the subscriber are routed to a PCS service node which will re-route the call according to the subscriber's service profile stored in a database. The service node insures that attempts to communicate with the subscriber are handled with appropriate consideration for who is calling, when the call is made, and the urgency of the call. In addition, the subscriber is given control over how the system will work for them in routing incoming calls.

Why it's free to use

  • Filed May 5, 1993 and granted June 16, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 5, 2013.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 5, 2015.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
