Why it's free to use
- Filed November 10, 2000 and granted November 4, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 10, 2020.

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