Open the CIPO recordAbstract From the Canadian patent
The present invention relates to a cutter for cutting the ends from a mini blind so that the mini blind may be custom sized for a particular window opening. The mini blind cutter includes a framework which has a receiving area for receiving an end of the mini blind. A cutter blade is attached to a slide bar which is slidably mounted in the framework. The slide bar includes a rack engaged with a pinion gear that is rotated by a ratchet handle. Movement of the ratchet handle thus slides the slide bar along the framework and forces the cutter blade through the end of the mini blind.

Why it's free to use
- Filed January 24, 1994 and granted March 18, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 24, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 24, 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.
