Open the CIPO recordAbstract From the Canadian patent
A method of constructing a water-resistant corner for a tent or other fabric structure and the corner formed therefrom. A protective panel may be laid over a flooring material sheet and the sheet and the protective panel are folded into a corner. The formed corner may then be turned inside out so that the protective panel is located on the outside of the newly-formed corner. The protective panel thereby covers the outermost corner of the flooring and the seam formed at that corner. An interior waterproof layer such as a waterproof sealing tape, may be attached on the inside of the inverted corner to act as a further moisture barrier.

Why it's free to use
- Filed October 17, 2002 and granted June 12, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 17, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 17, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
