Open the CIPO recordAbstract From the Canadian patent
A kickboard for training a swimmer has a posterior transverse edge that defines a pair of handholds to encourage a natural and relaxed grip. The posterior edge further defines a notch adapted to partially envelop the swimmer's head or torso and to create additional space between the swimmer and the kickboard. The kickboard is further characterized by a pair of posterior arm-supports and a pair of lateral fins for engaging the swimmer's forearms to reduce fatigue and increase control. The kickboard also defines a pair of indentations in its broad surface for engaging the balls of the swimmer's hands to facilitate open-handed control.

Why it's free to use
- Filed February 2, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 2, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 2, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
