Abstract From the Canadian patent

A method for automated service provisioning for telecommunications companies. A caller establishes a connection with the company and requests one or more service changes. The caller's voice or DTMF tone information is converted into data compatible with the processors of the automated method. The caller's data is then validated to determine whether the caller is an existing customer entitled to the requested service. Upon proper validation, a service order is automatically generated and the service, order is processed. In some embodiments a log feature logs the caller's telephone number to enable a subsequent dial back confirming that the order has been executed.

Why it's free to use

  • Filed September 29, 1997 and granted October 31, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 29, 2017.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 29, 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.
