Why it's free to use
- Filed November 28, 1989 and granted January 18, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 28, 2009.

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