Open the CIPO recordAbstract From the Canadian patent
A multilayer automotive hose includes an innermost layer of elastomer material, and a separate outermost layer of elastomer material, each including between about 40% and about 80% vinylacetate by weight in a copolymer. The elastomer layers are formed by an extrusion process. The vinylacetate is copolymerized with polyethylene. Each of the elastomer layers has a fully saturated backbone. As a result, each of the innermost and outermost layers is a non-thermoplastic elastomer.

Why it's free to use
- Filed October 11, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 11, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 11, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
