Open the CIPO recordAbstract From the Canadian patent
The subject invention concerns Bacillus thuringiensis isolates designated B.t. PS157C1, B.t. PS86A1 and B.t. PS75J1, which are active against aphid pests. Thus these isolates, or variants thereof, can be used to control such pests. Further genes encoding novel .delta.-endotoxins can be removed from these isolates and transferreed to other host microbes or plants. Expression of the .delta.-endotoxins in microbe hosts results in the control of aphid pests, whereas transformed plants become resistant to aphid pests.

Why it's free to use
- Filed August 6, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 6, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 6, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
