Why it's free to use
- Filed April 7, 2005 and granted October 8, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 7, 2025.
- 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.
