Open the CIPO recordAbstract From the Canadian patent
A buttoning accessory for facilitating one-hand passage of a button through a buttonhole has a flexible handle to one end of which is secured a flat retainer having two substantially right-angular limbs each of which has a slot therein. The angular relationship of the limbs forms an elbow having an inside edge and an outside edge. Both the handle and the retainer are of such width and thickness as to pass freely through the buttonhole. Movement of the accessory through the buttonhole causes a button accommodated in the slot of the retainer also to pass through the buttonhole.

Why it's free to use
- Filed November 14, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 14, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 14, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
