Why it's free to use
- Filed August 10, 1999 and granted October 11, 2016. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 10, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 10, 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.
