Patents by Inventor Richard A. Winchurch

Richard A. Winchurch 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: 10799600
    Abstract: The invention in the various aspects provides nanogel compositions that are safe for topical, local, and/or systemic delivery, and which can be targeted to select tissues or cells, including pathogens. In some embodiments, conjugation of antibiotics to the nanogel surface, and in particular antibiotics that disrupt outer membranes of Gram negative bacteria or antibiotics that inhibit cell wall synthesis, provide for highly effective targeting and killing of bacterial pathogens, including drug-resistant bacteria.
    Type: Grant
    Filed: April 15, 2019
    Date of Patent: October 13, 2020
    Assignee: NANODERM SCIENCES, INC.
    Inventors: Roy R. Yeoman, Richard A. Winchurch

  • Patent number: 9694085
    Abstract: Disclosure of methods and compositions related to chemical conjugations to nanoparticles of polysaccharides cross-linked to poloxamers as well as nano-sized colloids comprised of polysaccharides and poloxamers. The nanoparticles may be produced by various methods including inverse miniemulsion polymerization processes which create nanogels of desired size, shape, and stability for controlled therapeutic drug delivery, imaging, and theragnostic applications.
