Open the CIPO recordAbstract From the Canadian patent
The present invention relates to a method for the treatment of cerebral ischaemia and a drug for the treatment of cerebral ischaemia in particular in humans, as occurs for example in the case of stroke patients. It was found surprisingly that peripheral administering of erythropoietin to the , cerebral tissue affected by the ischaemia has a distinctly protective effect. Erythropoietin has the effect thereby that the region of the cerebral tissue which is damaged permanently, in particular in the penumbra is dramatically , reduced relative to conventional measures in the case of cerebral ischaemia without erythropoietin administration.

Why it's free to use
- Filed December 13, 1999 and granted May 17, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 13, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 13, 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.
