Why it's free to use
- Filed December 9, 1993 and granted February 12, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 9, 2013.

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