Why it's free to use
- Filed December 23, 1996 and granted April 11, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 23, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 23, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
