Edward E. Sponsler 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).

  • Patent number: 5639505
    Abstract: Articles of manufacture which are adapted for use in contact with one or more biologically active agents are coated with a glassy carbohydrate film. The glassy film provides a reduced surface energy coating which exhibits a reduced degree of binding with biologically active agents. Methods for applying the glassy carbohydrate film are disclosed wherein the glassy film is adsorbed directly onto the article surface.The coated articles are for use both in vitro and in vivo where contact with biologically active agents is expected.
    Type: Grant
    Filed: May 23, 1995
    Date of Patent: June 17, 1997
    Assignee: The Regents of the University of California
    Inventors: Nir Kossovsky, Andrew E. Gelman, Edward E. Sponsler

  • Patent number: 5334394
    Abstract: A biologically active composition made up of core particles having diameters of less than about 1000 nanometers which are coated with a layer which is designed to allow attachment of biologically active proteins, peptides or pharmacological agents to the microparticles. When Human Immunodeficiency Virus (HIV) viral protein is attached to the core particles, the result is a viral decoy which accurately mimics native HIV in size, structure and surface character while being entirely devoid of virulent activity due to the microparticle core. The HIV decoy is useful as a vaccine for treating mammals to elicit an immune response.
    Type: Grant

  • Patent number: 5306508
    Abstract: A red blood cell surrogate which is composed of a nanocrystalline core particle to which an oxygen carrier such as hemoglobin is bound. An oxygen carrier anchor coating is provided between the nanocrystalline core particle and the oxygen carrier in order to provide binding of the oxygen carrier to the nanocrystalline core particle without denaturing the oxygen carrier or otherwise destroying its oxygen carrying capacity. The nanocrystalline core particle with the oxygen carrier bound thereto is coated with an exterior layer of lipid.
