Abstract From the Canadian patent

A target analyte which may be found in a substance such as a biological or environmental substance is assayed by inoculating a media with a sample of the substance. The target analyte is a unique nucleotide sequence of the RNA or DNA of a suspect organism or any nucleotide target, or a combination of nucleotide sequences thereof which organism may be found in the substance. The media contains selected target analyte amplifiers which will result in the amplification of any target analytes which are present in the substance. The media may also contain one or more labeled analyte-specific materials (LASMs) which can migrate through the media. The nature of the media is such that it will …

Why it's free to use

  • Filed February 5, 1998 and granted January 29, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 5, 2018.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 5, 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.
