Why it's free to use
- Filed January 22, 2001 and granted February 28, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 22, 2021.

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