Abstract From the Canadian patent

Methods for determining quantities of nucleic acid sequences in samples include the steps of amplifying a plurality of known quantities of a nucleic acid sequence in respective calibration samples and an unknown quantity of a nucleic acid sequence in a test sample in parallel, during a, time interval. These samples may be amplified using an isothermal amplification method such as Strand Displacement Amplification (SDA) or a, thermal cycling amplification method such as Polymerase Chain Reaction (PCR), for example. Indicia of the quantities of a nucleic acid sequence being amplified in the calibration and test samples are then measured using conventional techniques, at measurement points in …

Why it's free to use

  • Filed April 27, 1998 and granted August 5, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 27, 2018.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 27, 2020.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
