Open the CIPO recordAbstract From the Canadian patent
Modified plants are disclosed which have enhanced starch-producing capability as a result of a change in the concentration of one or more of the metabolites which take part in glycolysis and the TCA cycle in the plant. The effect may be achieved for example by a genetic modification to reduce the activity of NAD-malic enzyme.

Why it's free to use
- Filed November 27, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 27, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 27, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
