Open the CIPO recordAbstract From the Canadian patent
Particles of edible fat are precrystallised at edible fat and are blended with an aqueous ice cream precursor phase in the presence of at least one emulsifier to form a dispersion. The precrystallised particles of edible fat each contain a multiplicity of individual crystals. The resulting dispersion is gasified and frozen so as to form an ice cream. The precrystallisation is preferably performed cryogenically.

Why it's free to use
- Filed August 12, 2003 and granted October 9, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 12, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 12, 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.
