Why it's free to use

  • Filed May 13, 2004 and granted November 24, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 13, 2024.

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