Abstract From the Canadian patent

An endless drive track for a snowmobile is provided with traction lugs that are inclined relative to normal to the track base. When the traction lugs are inclined away from the direction of travel for the track the traction lugs can compress the snow before engaging the snow for traction thereby providing lift for a snowmobile traveling in deep snow.

Why it's free to use

  • Filed February 23, 2004 and granted August 6, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 23, 2024.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 23, 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.
