Tim Keen 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).

  • POLYVALENT, PRIMARY HIV-1 GLYCOPROTEIN DNA VACCINES AND VACCINATION METHODS
    Publication number: 20110171258
    Abstract: Polyvalent, primary isolate nucleic acid compositions for inducing an immune response against HIV is disclosed. The compositions and methods described herein are for the use of a DNA composition that encodes one or more different HIV envelope glycoproteins. The DNA composition can encode an HIV Gag protein. The DNAs encoding one or more HIV proteins are a combination of different nucleic acids, such as DNA plasmids, generated from primary isolate DNA of different HIV major group genetic clades and/or different proteins. HIV protein compositions for inducing an immune response against HIV are disclosed. Methods for using the protein compositions as boosts following administration of the DNA compositions are provided.
    Type: Application
    Filed: February 3, 2011
    Publication date: July 14, 2011
    Applicants: UNIVERSITY OF MASSACHUSETTS, ADVANCED BIOSCIENCE LABORATORIES, INC.
    Inventors: Shan Lu, Shixia Wang, Ranajit Pal, Vaniambadi Kalyanaraman, Stephen Charles Whitney, Tim Keen, Balachandran Nair, Phillip Markham
