Abstract From the Canadian patent

Methods for detecting the presence of Neisseria gonorrhoeae are described. Thesemethods are based upon amplifying a portion of the Neisseria gonorrhoeae genome and detecting the presence of the amplified nucleic acid. Various sets of primers and detectors are disclosed. The disclosed primers and detectors can be used in Strand Displacement Amplification assays, thermal Strand Displacement Amplification Assays and homogeneous, fluorescent real time thermal Strand Displacement Amplification assays to specifically detect the presence of Neisseria gonorrhoeae even in the presence of contaminating microorganisms and in the presence of human DNA.

Why it's free to use

  • Filed November 2, 1998 and granted December 31, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 2, 2018.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 2, 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.
