Why it's free to use

  • Filed May 10, 2006 and granted May 1, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 10, 2026.

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