Open the CIPO recordAbstract From the Canadian patent
A method is disclosed to detect and to determine subtypes of HCV antibodies in a large number of samples efficiently, and to provide oligonucleotides and oligopeptides used in the method directly and indirectly. Also disclosed is a detection system and a determination system of HCV antibody using one or more of oligopeptides described in SEQ ID 3 and 4. Oligopeptides can be obtained by means of chemical synthesis. Also oligopeptides can be obtained by means of gene technology with genetic recombination of oligonucleotides having the nucleotide sequence described in SEQ ID 1 and 2 and those coding, for oligopeptides having the amino acid sequence described in SEQ ID 3 and 4, into a host cell.

Why it's free to use
- Filed December 23, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 23, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 23, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
