Open the CIPO recordAbstract From the Canadian patent
A subscriber-defined call processing program designed for execution in a communications network is subjected to testing procedures which simulate a call processing environment involving the execution of the program. The testing procedures assess the program's fitness for execution in a communications network and compute threshold values of network resource consumption by calls invoking execution of the program so that those calls can be terminated when those threshold values are exceeded in the course of processing those calls in the communications network.

Why it's free to use
- Filed November 16, 1993 and granted June 17, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 16, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 16, 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.
