Open the CIPO recordAbstract From the Canadian patent
The invention is directed to expression of non-plant proteins in rice plants. Expression is optimized by use of a non-rice promoter of a monocot protein gene and its corresponding signal peptide for expression of the non-plant protein in rice plant at high yields. The invention is useful for making human proteins, polypeptides and peptides in rice seeds. The expressed protein product can be isolated from the rice seed for administration to humans or other animals.

Why it's free to use
- Filed December 23, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 23, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 23, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
