Open the CIPO recordAbstract From the Canadian patent
Electrodeionization is used to demineralize milk products and derivatives with cationic ion exchange resins and weakly anionic ion exchange resins in a mixed bed or with, a strongly cationic resin alone in the dilution and concentration compartments if raw materials are treated other than more or less concentrated milk. In the case where more or less concentrated milk is used as a raw material, the dilution compartments are filled with cationic ion exchange resins and weakly anionic exchange resins in a mixed bed. The process enables considerable savings to be made in water and energy without using regenerating chemicals.

Why it's free to use
- Filed October 1, 1997 and granted January 15, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 1, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 1, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
