Open the CIPO recordAbstract From the Canadian patent
Methods and compositions are provided for remodeling nuclear donor material used in nuclear transfer procedures. By exposing donor chromatin to one or more exogenous remodeling factors, the limited ability of mammalian oocytes to remodel the chromatin of differentiated cells including fetal and live-born , somatic cells can be increased, resulting in dramatically improved cloning efficiencies.

Why it's free to use
- Filed June 14, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 14, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 14, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
