Why it's free to use
- Filed May 26, 1994 and granted July 27, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 26, 2014.

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