Open the CIPO recordAbstract From the Canadian patent
This patent application discloses new genes the expression of which is inducible by SAR inducing compounds, and in a particular embodiment by both SAR inducing compounds and ISR inducing compounds. These genes enable the establishment of novel methods for testing chemical compounds and natural products for their capability to induce an enhanced resistance status (ERS) and particularly SAR or ISR, in plants and for screening a multiplicity of chemical compounds, for compounds or compositions having the capability to induce ERS in plants. This disclosure also enables the use of recombinant DNA molecules comprising these DNA molecules in transgenic plants to confer enhanced tolerance …

Why it's free to use
- Filed May 19, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 19, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 19, 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.
