Open the CIPO recordAbstract From the Canadian patent
A process for thinning stone fruit blossoms is disclosed. In the process, a compound selected from certain alkoxylated amines and alkoxylated quaternary ammonium compounds is applied to stone fruit trees at some point after 50% blossom to thereby reduce the number of blossoms on the stone fruit tree. In this manner the amount of fruit thinning which must be done by hand can be substantially reduced without decreasing the quantity of marketable fruit produced by an orchard or harming the trees or the workers in the orchard.

Why it's free to use
- Filed June 25, 1991 and granted August 28, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 25, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 25, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
