A granule with an allergenic component has reduced dust by including antifoam added during the production of the granule. The antifoam may be dispersed throughout the granule or added to one of the components of the granule. The granule with antifoam produces at least 30 % less dust than a comparable granule produced according to a process in which no antifoam is added.

Why it's free to use
- Filed April 1, 2002 and granted July 10, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 1, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 1, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
