Why it's free to use
- Filed November 23, 2000 and granted May 1, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 23, 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.
