Open the CIPO recordAbstract From the Canadian patent
A non-linear cryopreservation protocol and method for improving cryopreservation protocols for cells involves producing a simulation of cellular responses to a range of cooling parameters; determining optimal cooling parameters required to minimize cryoinjury to the cells; and incorporating optimal parameters into the protocol. The simulation is based on mathematical models of cellular parameters. A non-linear cryopreservation protocol for cryopreserving stem cells is also diclosed.

Why it's free to use
- Filed September 17, 2004 and granted September 16, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 17, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 17, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
