Why it's free to use
- Filed January 15, 1997 and granted November 30, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 15, 2017.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
