Open the CIPO recordAbstract From the Canadian patent
A method of manufacturing particles, especially nanoparticles by way of , precipitation from solution on a rotating surface (1) of a rotating surface reactor is disclosed. Nanoparticles with a tight size distribution may be manufactured in bulk and without the problems of agglomeration that are associated with traditional stirred-tank reactors. Use of a rotating surface reactor allows precipitation of nanoparticles from viscous supersaturated , solutions by way of homogeneous nucleation aided by strong micromixing.

Why it's free to use
- Filed July 22, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 22, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 22, 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.
