Patents by Inventor Darin K. Griffith

Darin K. Griffith 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: 8148312
    Abstract: The invention provides an aqueous bleaching solution for substrate treatment comprising a source of oxidant and a suspended polymer matrix having a plurality of optically functional particles associated with one or more copolymers present in the polymer matrix. The plurality of optically functional particles are associated with the copolymer during polymerization of at least one hydrophobic and at least one hydrophilic monomer so as to form a polymer matrix useful to impart an aqueous bleaching solution with optically functional properties providing a benefit to the solutions during storage, use and application to substrates for treatment.
    Type: Grant
    Filed: September 20, 2011
    Date of Patent: April 3, 2012
    Assignee: The Clorox Company
    Inventors: Thomas W. Kaaret, Darin K. Griffith, Klein A. Rodrigues, William L. Smith
