Open the CIPO recordAbstract From the Canadian patent
Live, attenuated Delaware infectious bursal disease viruses are screened for effectiveness by a monoclonal antibody specific for said Delaware strain. Those which are not bound by the antibody are not or may not be as effective in conferring protection against homologous wild type infectious bursal disease infection. Currently available live attenuated vaccines do not include a virus having the binding site specified. A monoclonal antibody specific for the Delaware strain also provides a vaccine for passive immunization.

Why it's free to use
- Filed September 1, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 1, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 1, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
