Why it's free to use
- Filed July 26, 1991 and granted April 30, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 26, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 26, 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.
