Why it's free to use
- Filed November 20, 2002 and granted January 20, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 20, 2022.

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