Patents by Inventor Anthony R. Welch

Anthony R. Welch 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).

  • Herpes virus proteinase and method of assaying
    Patent number: 6410296
    Abstract: A herpes virus proteinase has been found to be encoded by a member of a family of four nested genes in simian cytomegalovirus. Another member of the nested genes encodes the assembly protein precursor, which is a substrate for the proteinase. Homologous genes are found in other herpes viruses. Cleavage sites recognized by the proteinase are identified in cytomegalovirus and are found to be highly conserved in other herpes viruses. Substrates, inhibitors, assay kits, and methods of assaying are provided which rely on the proteinase and its activity.
    Type: Grant
    Filed: June 2, 2000
    Date of Patent: June 25, 2002
    Assignee: Johns Hopkins University
    Inventors: D. Wade Gibson, Anthony R. Welch
