Why it's free to use

• Filed June 22, 1999 and granted September 10, 2002. 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.
