Open the CIPO recordAbstract From the Canadian patent
A track for a snow vehicle is described herein. The track is provided with two different rows of lugs that together define a generally smooth convex profile. The lugs of the first and second rows are staggered, thereby allowing an adequate traction even when the vehicle is severely tilted, without defining a ski-like outer profile that would cause the vehicle to slide sideways.

Why it's free to use
- Filed September 2, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 2, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 2, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
