Open the CIPO recordAbstract From the Canadian patent
A method of characterizing a nucleic acid molecule is disclosed. The method comprises synthesizing DNA in the presence of a reaction mixture comprising a nucleic acid template, a primer molecule an enzyme that extends the primer so , that a DNA molecule may be synthesized four canonical deoxynucleoside , triphosphates and at least one non-canonical deoxynucleoside triphosphate. The non-canonical deoxynucleoside triphosphate is incorporated into the synthesized DNA in place of a portion of only one canonical deoxynucleoside triphosphate. The synthesized DNA is treated with an N-glycosylase that excises a base portion of the non-canonical deoxynucleoside triphosphate from the …

Why it's free to use
- Filed September 25, 1996 and granted August 27, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 25, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 25, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
