Open the CIPO recordAbstract From the Canadian patent
The inventions relates to a fractionation or screening device with a fractionation or screening structure and a bearing for mounting the fractionation or screening structure on a rigid machine base. The bearing (5 12, 15) has greater compliance than the fractionation or screening structure (1 6a) itself, thus excess stress can be avoided in the fractionation or screening structure.

Why it's free to use
- Filed September 24, 2004 and granted June 26, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 24, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 24, 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.
