Why it's free to use
- Filed January 4, 1994 and granted February 25, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 4, 2014.

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