Open the CIPO recordAbstract From the Canadian patent
A method of mutagenesis by which a predetermined amino acid is introduced into each and every position of a selected set of positions in a preselected region (or several different regions) of a protein to produce library of mutants. The method is based on the premise that certain amino acids play crucial role in the structure and function of proteins. Libraries can be generated which contain a high proportion of the desired mutants and are of reasonable size for screening. These libraries can be used to study the role of specific amino acids in protein structure and function and to develop new or improved proteins and polypeptides such as enzymes, antibodies, single chain antibodies …

Why it's free to use
- Filed April 5, 1991 and granted September 18, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 5, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 5, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
