Abstract From the Canadian patent

In accordance with the invention, nucleic acid polymers are sequenced in a method comprising the steps of: a) obtaining forward and reverse data sets for forward and reverse strands of the sample nucleic acid; b) determining the apparent sequence of bases for the forward and reverse data sets; c) comparing the apparent forward and reverse sequences of basis for perfect complementarity to identify any deviations from complementarity in the apparent sequence, any such deviation presenting a choice between two bases only one of which is correct; d) applying a confidence algorithm to peaks in the data set associated with a deviation to arrive at a numerical confidence value; and e) …

Why it's free to use

  • Filed June 25, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 25, 2019.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 25, 2021.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
