Open the CIPO recordAbstract From the Canadian patent
A mat adapted to relieve fatigue in a person standing on it without shoes or boots, and formed from fine cell foam having a density of between 1.5 and 2.5 pounds per cubic foot, with thickness between 0.75 and 1.5 inches, and a compression strength at 25% compression of between 10 and 17 p.s.i. The mat has sloping edges and is covered by carpet. When a person in bare or stocking feet stands on the mat, the mat partially compresses but has remaining resiliency such as to produce a swaying motion in the person. This results in increased muscle action and blood circulation in the feet, legs and hips and some spinal movement, reducing fatigue.

Why it's free to use
- Filed April 11, 1994 and granted June 16, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 11, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 11, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
