Patents by Inventor Massimo Levredo

Massimo Levredo 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).

  • Adenoviral vector with a deletion in the E1A coding region expressing a hetorologous protein
    Patent number: 6696420
    Abstract: Recombinant DNA modified by a nucleotide sequence coding for a specific polypeptide sequence whose expression is sought, this recombinant DNA being appropriate to the transformation of eucaryotic cell lines, notably human or animal, the endogenous polymerases of which are susceptible of recognizing the adenovirus promoters. The DNA according to the invention is more particularly characterized by the fact that the said insertion nucleotide sequence is placed under the direct control of the early promoter of the E1A region of the genome of adenovirus.
    Type: Grant
    Filed: July 20, 1993
    Date of Patent: February 24, 2004
    Assignees: Institut Pasteur, Centre National de la Recherche Scientifique, Institut National de la Sante et de la Recherche Medicale
    Inventors: Michel Perricaudet, Annick Ballay, Massimo Levredo, Pierre Tiollais
