James Christopher Stephen Clegg 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).

  • Method of making microencapsulated DNA for vaccination and gene therapy
    Patent number: 6743444
    Abstract: A method of making a microparticle that contains DNA coding for a polypeptide is described in which a solvent extraction method is used and solvent extraction takes place at elevated temperature. Oral administration of the microparticle leads to its expression. DNA coding for an immunogen is for stimulating antibody formation in a recipient and DNA coding for a non-immunogenic polypeptide is for gene therapy applications. DNA is incorporated into the microparticle without destruction of its function.
    Type: Grant
    Filed: July 3, 2001
    Date of Patent: June 1, 2004
    Assignee: Microbiological Research Authority
