Why it's free to use
- Filed July 25, 1990 and granted September 12, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 25, 2010.

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