Open the CIPO recordAbstract From the Canadian patent
A new approach in the field of plant gums is described which presents a new solution to the production of hydroxyproline(Hyp)-rich glycoproteins (HRGPs) repetitive proline-rich proteins (RPRPs) and arabino-galactan proteins (AGPs). The expression of synthetic genes designed from repetitive peptide sequences of such glycoproteins, including the peptide sequences of gum arabic glycoprotein (GAGP), is taught in host cells including plant host cells.

Why it's free to use
- Filed July 21, 1998 and granted May 10, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 21, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 21, 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.
