Open the CIPO recordAbstract From the Canadian patent
Vigour of various types of seed is determined by measuring volatile gases emitted from the seed when exposed to various conditions. For example ethanol produced by canola (Brassica napus) seed in an enclosed container stored, for 24 hours at room temperature after the seed has been made up to 20 % moisture, is measured by gas chromatography or by colour change in an indicator substance. The quantity of ethanol determined by either method of analysis indicates the vigour, of the seed.

Why it's free to use
- Filed April 18, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 18, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 18, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
