Why it's free to use
- Filed February 28, 1992 and granted September 23, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 28, 2012.

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