Open the CIPO recordAbstract From the Canadian patent
An aqueous foam-forming composition of physiologically acceptable quality having a viscosity not below 5 cP to be used for homogeneously incorporating water to a lipophilic phase. The lipophilic phase is liquefied or ground to a powder and there is incorporated therein by blending a foam of fine air or gas bubbles in the composition, then it is allowed to cool and degas. The foam formation is due to the presence of a foamer for instance an amphipatic surfactant, and it is stabilized by viscosity enhancers and thickeners. The method is applied to the hydration of chocolate in order to improve its storage stability and heat resistance; the foamer can be selected from esters of fatty acids …

Why it's free to use
- Filed June 27, 1990 and granted January 2, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 27, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 27, 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.
