Open the CIPO recordAbstract From the Canadian patent
The invention relates to methods of genotyping single nucleotide differences in a nucleic acid sample. More particularly the invention provides methods of , identifying the nucleotide at a polymorphic site or a group of polymorphic sites in a sample of genomic DNA. The method uses tagged primer extension in which a set of tag sequences correspond to the identity of the nucleotides at the polymorphic sites. Primer extension products are PCR amplified using a common set of tag-specific primers, the downstream primers bearing distinguishable labels. Following separation by size and/or charge the , detection of distinguishable label in a product of the anticipated size determines the …

Why it's free to use
- Filed June 20, 2003 and granted September 11, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 20, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 20, 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.
