Open the CIPO recordAbstract From the Canadian patent
This invention relates to recombinant DNA-technology. Specifically this invention relates to new recombinant yeast cells transformed with SEB1 gene. Yeast cells transformed with several copies of SEB1 gene or overexpressing , the Seb1 protein by some other means have an increased capacity to produce secreted foreign or endogenous proteins. Further said new recombinant cells, when transformed with genes expressing suitable hydrolytic enzymes can utilize appropriate macromolecular compounds more efficiently which results in , increased cell mass production and/or more versatile utilization of the compounds in relevant biotechnical applications.

Why it's free to use
- Filed July 8, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 8, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 8, 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.
