Why it's free to use

  • Filed September 28, 2005 and granted September 3, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 28, 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.
