Open the CIPO recordAbstract From the Canadian patent
An ice fishing device for trapping a fish in a hole in the ice includes a pair of coaxial, hollow cylinders one, of which is slidably mounted in the other. Flexible fingers extend inwardly from the outer cylinder through slots in the bottom end of the inner cylinder. The fingers have inwardly curving upper ends, so that downward movement of the inner cylinder into the outer cylinder causes the fingers to move inwardly to define a partial wall or gate, which prevents the escape of a fish from within the inner cylinder.

Why it's free to use
- Filed March 10, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 10, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 10, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
