Open the CIPO recordAbstract From the Canadian patent
A cutter link for a chain saw chain containing a conical raker spaced forward of a round cutter face. The raker protects most of the cutter face from sudden impact and, together with the cutting and rake angles of the cutter face, provides for a filing rather than a chiseling action by the cutter link. Saw chains incorporating the novel cutter link are impact and wear resistant.

Why it's free to use
- Filed January 23, 1991 and granted September 3, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 23, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 23, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
