Open the CIPO recordAbstract From the Canadian patent
High-fiber baked goods contain an improved powdered cellulose fiber derived from cottonseed linters. The powder has a very small particle size and good hydration capability. As compared with cellulose derived from wood, the baked goods have improved volume. The combination of small particle size and good hydration characteristics permits the substitution of the powdered cellulose for a large percentage of the flour in bread to create high-fiber and/or reduced-calorie breads.

Why it's free to use
- Filed January 17, 1990 and granted January 9, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 17, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 17, 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.
