Richard T. Richardson 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).

  • Sperm antigen corresponding to a sperm zona binding protein autoantigenic epitope
    Patent number: 5820861
    Abstract: The present invention involves DNA encoding a mammalian Sp 17 protein, particularly human Sp17 protein, or antigenic peptides which are fragments thereof, along with said antigenic fragments. These proteins and peptides are useful as immunocontraceptive agents and/or for the diagnosis of autoimmune infertility. Avirulent host cells which express the antigenic proteins or peptides and which are useful as immunocontraceptive agents are also disclosed.
    Type: Grant
    Filed: May 8, 1995
    Date of Patent: October 13, 1998
    Assignee: The University of North Carolina at Chapel Hill
    Inventors: Michael G. O'Rand, Esther E. Widgren, Richard T. Richardson, Isabel A. Lea
