Why it's free to use

  • Filed March 29, 1996 and granted September 5, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 29, 2016.

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