Melissa Holstein 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: 11732003
    Abstract: Methods of maintaining narrow residence time distributions in continuous flow systems, particularly applicable to virus inactivation such as during a protein purification process. Fluid sample is introduced into an axial flow channel and caused to flow therein in discrete packets or zones to minimize residence time distribution and axial dispersion. Embodiments described herein obviate or minimize the need for using large tanks or reservoirs for performing virus inactivation during a protein purification process; reduce the overall time required for virus inactivation, and/or reduce the overall physical space required to perform the virus inactivation operation during a protein purification process, which in turn reduces the overall footprint for the purification process.
    Type: Grant
    Filed: April 18, 2018
    Date of Patent: August 22, 2023
    Assignee: EMD Millipore Corporation
    Inventors: Ronald Tuccelli, John Caulmare, Luc Messier, Melissa Holstein, Christopher Gillespie, Roger Hill
