Open the CIPO recordAbstract From the Canadian patent
A tricistronic vector (i.e. a vector capable of expressing three exogenous genes, which are not fused together, under the control of one promoter) effectively can encode an immunoglobulin-presenting polypeptide and two immunoglobulin (Ig) polypeptides. The encoded Ig-presenting polypeptide is able to associate with at least one of the Ig polypeptides via co-expressed associating agents. A vector according to the present invention particularly is suited for phage display technology e.g. when the Ig-presenting , polypeptide is a phage coat protein and the Ig polypeptides associate to form a Fab.

Why it's free to use
- Filed July 30, 2003 and granted November 5, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 30, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 30, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
