Open the CIPO recordAbstract From the Canadian patent
The biosynthesis of lignin in plants is regulated by insertion into the plant genome by altering the plant's ability to synthesize the enzyme O-methyl-transferase, an enzyme involved in the lignin biosynthetic pathway. Production of O-methyl-transferase may be enhanced by insertion into the plant genome by transformation of one or more additional copies of the O-methyl-transferase gene or production may be inhibited by insertion of a gene encoding anti-sense mRNA directed against the mRNA encoded by the endogenous O-methyl-transferase gene.

Why it's free to use
- Filed September 9, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 9, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 9, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
