Abstract From the Canadian patent

A system for managing a telemarketing complex is disclosed wherein the probability of meeting a given performance objective by the agents servicing an automatic call distributor (ACD) within the complex is computed for each subinterval of a predetermined service interval. This probability is then compared with threshold levels in order to determine whether the ACD requires that calls be shifted to meet the performance objective or whether calls can be accepted by that ACD. A record is maintained for each subinterval of the probabilities computed for that subinterval and as to whether the system succeeded or failed in achieving the performance objective at the end of the service interval. …

Why it's free to use

  • Filed July 21, 1994 and granted August 18, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 21, 2014.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 21, 2016.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
