Open the CIPO recordAbstract From the Canadian patent
This invention relates to edging efficiency of a binding support type ski, taking advantage of the non linear relationship between edge to surface pressure and resistance to movement perpendicular to the ski edge. In the ski according to this invention, edging efficiency is enhanced by providing localized, longitudinally spaced edge to running surface high pressure sections improving both edge, control and ski directional stability. The ski comprises a novel ski runner wherein the longitudinal flex substantially resides in flanges adjacent to the ski runner side margins.

Why it's free to use
- Filed May 10, 1993 and granted July 18, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 10, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 10, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
