Open the CIPO recordAbstract From the Canadian patent
Microchannel devices and method of use are disclosed wherein a reaction microchamber (52) is in thermal contact with a heat exchange channel (61). An equilibrium limited exothermic chemical process occurs in the reaction microchamber (52). Sufficient heat is transferred to the heat exchange channels to substantially lower the temperature in the reaction microchamber (52) down its length to substantially increase at least one performance parameter of the exothermic chemical process relative to isothermal operation. Optionally, an endothermic reaction occurs in the heat exchange channel (61) which is sustained by the exothermic chemical process occurring the exothermic reaction …

Why it's free to use
- Filed March 11, 2003 and granted October 15, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 11, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 11, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
