Katherine Witherspoon 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).

  • Reproducible sample preparation method for quantitative stain detection
    Patent number: 10041866
    Abstract: A stain-barrier is described along with methods of its application to a fabric. The stain barrier reduces variability between samples of different dilution or fabric type so that limits of stain detection can be assigned more accurately and precisely and stain detection techniques can be transparently compared.
    Type: Grant
    Filed: April 22, 2016
    Date of Patent: August 7, 2018
    Inventors: Zhenyu Lu, Brianna Cassidy, Katherine Witherspoon, Stephanie Dejong, Raymond G. Belliveau, III, Michael Myrick, Stephen L. Morgan
  • Reproducible sample preparation method for quantitative stain detection
    Patent number: 9885147
    Abstract: A stain-barrier is described along with methods of its application to a fabric. The stain barrier can be applied to fabric samples and limits the amount of fabric with which deposited liquid is able to interact. This stain barrier reduces unwanted variability between samples of different dilution or fabric type so that limits of stain detection can be assigned more accurately and precisely and stain detection techniques can be transparently compared.
