Kay S. Faaberg 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).

  • Viable viruses with foreign tags
    Patent number: 10729756
    Abstract: Multiple DIVA vaccines effective against porcine reproductive and respiratory syndrome virus (PRRSV) are disclosed. The DIVA vaccines may be negative DIVAs or positive DIVAs. The DIVA vaccines may be produced by modifying the nsp2 region of a modified live virus vaccine. The modification may be one or more deletions only (negative DIVAs) or a deletion with an insertion (positive DIVAs). The insertion may be of an epitope tag, such as a V5, S-Tag, or FLAG tag. Produced DIVA vaccines may be stable through multiple passes and thus may be effective for production and vaccination of animals.
    Type: Grant
    Filed: May 25, 2018
    Date of Patent: August 4, 2020
    Assignee: The United States of America, as represented by the Secretary of Agriculture
    Inventors: Kay S. Faaberg, Allyn Spear, Matthew A. Kappes, Kelly M. Lager

  • Porcine reproductive and respiratory syndrome virus and methods of use
    Patent number: 7041443
    Abstract: The present invention provides isolated European-like porcine reproductive and respiratory syndrome viruses, polynucleotides, and polypeptides. The present invention also provides methods for making antibodies to the viruses and polypeptides, methods for detecting porcine reproductive and respiratory syndrome viruses, immunogenic compositions, and methods for treating a porcine subject at risk of infection by, or displaying symptoms of, a porcine reproductive and respiratory syndrome virus infection.
