Open the CIPO recordAbstract From the Canadian patent
This invention provides garments for firefighters including a coat and trousers, each of which is adapted to include an outer layer and an inner layer. One of the layers has an extension member which extends from that layer and which is attachable to the other layer as an indication that both layers are present in the garment. The extension member may also remain unattached to the other layer, and in an unattached condition provides an indication that the inner liner is present within the outer layer. Customarily, the extension member is attached to the inner layer and extends from the inner layer and from the outer layer to indicate that the inner layer is present within the outer layer.

Why it's free to use
- Filed May 14, 1990 and granted June 6, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 14, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 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.
