Why it's free to use

• Filed November 13, 1992 and granted January 21, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 13, 2012.
• A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 13, 2014.
• We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
