Why it's free to use
- Filed November 24, 1997 and granted January 18, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 24, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 24, 2019.
