Open the CIPO recordAbstract From the Canadian patent
A wind resistant and water vapor permeable composite fabric is provided. The composite fabric includes an inner fabric layer, an outer fabric layer and an intermediate vapor barrier. The vapor barrier may be selected from an adhesive material or an adhesive/membrane combination that is designed so that the fabric has a variable water vapor diffusion resistance which substantially decreases as air speed impinging on the fabric increases.

Why it's free to use
- Filed August 27, 1999 and granted January 3, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 27, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 27, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
