Open the CIPO recordAbstract From the Canadian patent
A vertical feed mixer has an auger with a center post that has an inclined upper surface that is substantially flat. Flights of varying shapes can be used. The upper part of the flight extends above the upper surface. The inclined upper surface increases the versatility and efficiency of the mixer since feed bales are unlikely to block the mixer.

Why it's free to use
- Filed August 10, 2000 and granted April 22, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 10, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 10, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
