Abstract From the Canadian patent

The invention relates to a method and test kit for quantitative determination of the amounts or relative proportions of polynucleotides in a mixture. The invention enables assessment of dynamic variations in a mixed population of organisms using affinity aided solution hybridization. The test kit comprises organized pools of polynucleotide probes having approximately the same number of nucleotides, which are distinguishable using resolution enabling tags providing the probes with different sizes. The resolution enabling tags may simultaneously act as tracer, affinity or primer tags. The probes are allowed to hybridize with affinity tagged analyte polynucleotides. The result is …

Why it's free to use

  • Filed July 4, 2003 and granted June 11, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 4, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 4, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
