Why it's free to use
- Filed April 28, 1999 and granted January 28, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 28, 2019.

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