Open the CIPO recordAbstract From the Canadian patent
The invention relates to nucleic acid sequences isolated from sugarcane and to methods of using them. In particular, the invention relates to nucleotide sequences which are derived from sugarcane polyubiquitin genes and which are capable of directing constitutive expression of a nucleic acid sequence of interest that is operably linked to the sugarcane polyubiquitin nucleotide sequences. The sugarcane polyubiquitin nucleotide sequences are useful in regulating expression of a nucleic acid sequence of interest in monocotyledonous and dicotyledonous plants.

Why it's free to use
- Filed March 18, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 18, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 18, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
