Open the CIPO recordAbstract From the Canadian patent
A method and apparatus for automatic area code dialing includes a processor software, and a memory for storing telephone numbers. At a dial tone a caller , dials a ten-digit number. The processor sends an area code dial request to the caller for future calls. The caller can confirm the request of the dialed number as a frequently-dialed number. The processor stores the number as a seven-digit portion and an area code portion. On subsequent calls to only the seven-digit portion of the number, the processor compares the seven-digit number to a group of stored numbers. If a match is found the processor , transmits both the seven-digit number and its corresponding area code.

Why it's free to use
- Filed January 27, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 27, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 27, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
