Why it's free to use
- Filed January 20, 1997 and granted October 31, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 20, 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.
