Open the CIPO recordAbstract From the Canadian patent
This invention relates to peptides and their preparation. The peptides each have a sequence that corresponds to the immunodominant region of the HIV-1 group O gp41 envelope protein. The sequence is characterized in that it does not correspond to any known naturally occurring group O sequence or variant. Furthermore the peptide binds anti-HIV-1 group O antibodies. There are several uses for the peptides including the detection of antibodies produced in response to HIV-1 group O infection. The peptides may also be incorporated in mosaics and expressed recombinantly.

Why it's free to use
- Filed November 23, 1999 and granted December 29, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 23, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 23, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
