Why it's free to use
- Filed May 5, 2006 and granted August 20, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 5, 2026.
- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
