Open the CIPO recordAbstract From the Canadian patent
The present invention relates to novel methods for making fusion proteins comprising a cytokine or growth factor fused to an immunoglobulin domain. The growth factor/cytokine can be fused directly to an immunoglobulin domain or through a peptide linker. The purified growth factor/cytokine-IgG fusion proteins produced by the novel methods are biologically active and can be used to treat diseases for which the non-fused growth factor/cytokine are useful.

Why it's free to use
- Filed July 13, 2000 and granted May 29, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 13, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 13, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
