Open the CIPO recordAbstract From the Canadian patent
A region of the Chlamydia trachomatis ItuB gene has been identified which is useful for performing amplification assays to determine specifically whether C. trachomatis is present in the sample being tested. Oligonucleotides useful for performing thermophilic Strand Displacement Assay (tSDA) reactions on this gene are disclosed. The disclosed oligonucleotides can be used in an assay which is specific for all strains of C. trachomatis and which does not show crossreactivity with the genomes of other microorganisms or with 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.
