Open the CIPO recordAbstract From the Canadian patent
A fishing device known as a spreader for trolling a plurality of baited hooks from a single fishing line wherein the spreader is a planar device with sweep arms extending from the body of the planar device and vanes that cause it to rotate as it moves relative to the water thereby causing, at least two fishing lures attached to the sweep arms to move in a helical pattern simulating the motion of fish swimming together. The hydrodynamic design provides for smooth operation in the water and reduces the propensity for the fishing lures to become entangled.

Why it's free to use
- Filed March 14, 1990 and granted January 4, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 14, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 14, 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.
