Why it's free to use
- Filed October 18, 1996 and granted April 25, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 18, 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.
