Why it's free to use
- Filed June 16, 1998 and granted January 28, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 16, 2018.

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