Open the CIPO recordAbstract From the Canadian patent
The present invention relates to a new useful and, humane foot-snare trap for trapping of fur-bearing animals. More particularly the invention relates to a unique snare trap design which utilizes a vertically oriented coiled spring which, when triggered releases, vertically to cause constriction of the snare about the leg of the animal in the trap. The vertical arrangement of the coiled spring leads to an upward release of the snare which provides a means to minimize the loss of snared animals while also minimizing the discomfort or injury to the animal and damage to the animal pelt by the recoil spring action.

Why it's free to use
- Filed February 16, 1990 and granted January 18, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 16, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 16, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
