Why it's free to use

  • Filed September 5, 2005 and granted November 3, 2020. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 5, 2025.

  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
