Why it's free to use
- Filed October 16, 1991 and granted May 21, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 16, 2011.

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