Open the CIPO recordAbstract From the Canadian patent
The present invention provides a method for enhancing the expression of genes in plants by supplying a virally encoded booster sequence comprising the 5' proximal region of the potyvirus genome to the plant. The booster sequence enhances the expression of foreign genes or endogenous plant genes in plants by employing any known methodology of expressing introduced genes in plants. The booster sequence may be used to enhance expression of any gene, including foreign genes or endogenous plant genes introduced by means of stable transformation into the genome of the plant or introduced by expression from a plant viral expression vector.

Why it's free to use
- Filed March 27, 1998 and granted March 1, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 27, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 27, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
