Why it's free to use
- Filed January 4, 1990 and granted March 13, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 4, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 4, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
