Open the CIPO recordAbstract From the Canadian patent
A method of characterizing a nucleic acid sample is provided that includes the steps of: (a) conducting a DNA polymerase reaction that includes the reaction of a template, a non-hydrolyzable primer at least one terminal phosphate-, labeled nucleotide DNA polymerase, and an enzyme having 3'.fwdarw.5' exonuclease activity which reaction results in the production of labeled polyphosphate; (b) permitting the labeled polyphosphate to react with a phosphatase to produce a detectable species characteristic of the sample; (c) detecting the detectable species; and (d) characterizing the nucleic acid sample based on the detection.

Why it's free to use
- Filed August 29, 2002 and granted December 10, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 29, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 29, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
