Why it's free to use
- Filed June 22, 1999 and granted October 14, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 22, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 22, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
