Open the CIPO recordAbstract From the Canadian patent
Products that are aerated multiphase systems containing an aqueous continuous fluid phase which may include solutes thus forming an aqueous syrup and disperse phases like gas/air cells, water ice crystals and solid/semi-solid fat globules or aggregates thereof, whereas the disperse phases are that finely structured that their mean diameters are below phase specific critical maximum values and thereby generate a most preferred by consumers full rich , silky-creamy mouth feel at much lower fat content than usual in conventional related products like premium and super premium ice creams.

Why it's free to use
- Filed July 7, 2004 and granted November 20, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 7, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 7, 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.
