Why it's free to use
- Filed February 12, 1991 and granted November 5, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 12, 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.
