The organic matrix of the composite article is formable at a temperature under about 150 ~C permits contact between an activating stimulus (e.g. water vapor and/or electromagnetic energy) and the C1O2-producing material when the composite article is exposed to the activating stimulus and is permeable to C1O2.

Why it's free to use
- Filed July 30, 2004 and granted October 29, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 30, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 30, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
