Patents by Inventor Stephane Villoing

Stephane Villoing has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12502426
    Abstract: The invention derives from the discovery that the immunogenicity of piscine orthoreovirus (PRV) can be significantly increased by inactivating the virus in a way different from the prior art: by incubation with an aziridine the vaccine potency against challenge infection by cohabitation is much improved over prior art approaches. This allowed the development of an effective inactivated vaccine against infection and disease caused by PRV.
    Type: Grant
    Filed: December 15, 2020
    Date of Patent: December 23, 2025
    Assignee: Intervet Inc.
    Inventors: Johanna Jacoba Elisabeth Bijlsma, Sven Leininger, Stephane Villoing
  • Publication number: 20230174996
    Abstract: The present invention is directed to a reassorted ISA virus comprising Genome segments 1-8 wherein at least one genome segment is from Genotype I and at least one genome segment is from genotype II, wherein genome segment 6 is of Genotype II. The reassorted ISA virus was found to grow well in suspension culture. The present invention is also directed to method to make the reassorted virus as well as vaccination methods using the reassorted ISA virus and to vaccine compositions comprising the reassorted ISA virus.

  • Patent number: 7794724
    Abstract: The present invention relates to veterinary immunology, namely to the immunological response of fish to a virus. More specifically, the invention provides an epitope of salmonid alphaviruses which epitope is capable of inducing a virus neutralising immune response. In particular the invention relates to a polypeptide comprising a certain amino acid sequence, a protein comprising such polypeptide, to a carrier comprising such protein, and to a method of producing antibodies. Further the invention relates to a nucleic acid encoding such polypeptide or such protein, and to a carrier comprising such a nucleic acid. Also, the invention relates to a vaccine and a diagnostic kit comprising such a polypeptide, protein, carrier, or nucleic acid.
