Why it's free to use
- Filed October 23, 1990 and granted August 2, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 23, 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.
