Why it's free to use
- Filed March 25, 1993 and granted February 18, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 25, 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.
