Richard L. BEARDSLEY 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).

  • Chromatography method for quantifying a non-ionic surfactant in a composition comprising the non-ionic surfactant and a polypeptide
    Patent number: 11680931
    Abstract: The invention provides methods for quantifying a non-ionic surfactant in a composition comprising a polypeptide and the non-ionic surfactant, where the quantification exhibits reduced interference between the non-ionic surfactant and the polypeptide. Also provided are methods where the composition further includes N-acetyl tryptophan, and the quantification exhibits reduced interference between the non-ionic surfactant, the polypeptide, and N-acetyl tryptophan.
    Type: Grant
    Filed: April 11, 2022
    Date of Patent: June 20, 2023
    Assignee: Genentech, Inc.
    Inventors: Mary Montti, Richard L. Beardsley, Michael S. Chinn
