Abstract From the Canadian patent

Conformational epitopes of the envelope protein E2 of the Hepatitis C virus (HCV) have been identified and characterized using a panel of monoclonal antibodies derived from patients infected with HCV. These conformational epitopes have been determined to be important in the immune response of humans to HCV and may be particularly important in neutralizing the virus. Based on the identification of these conformational epitopes vaccines containing , peptides and mimotopes with these conformational epitopes intact may be prepared and administered to patients to prevent and/or treat HCV infection. The identification of four distinct groups of monoclonal antibodies with each directed to …

Why it's free to use

  • Filed November 30, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 30, 2021.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 30, 2023.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
