Why it's free to use
- Filed March 31, 1993 and granted January 12, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 31, 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.
