Patents by Inventor Curtis Hewitt

Curtis Hewitt 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: 11939597
    Abstract: This invention relates to modified parvovirus inverted terminal repeats (ITRs) that do not functionally interact with wild-type large Rep proteins, synthetic Rep proteins that functionally interact with the modified ITRs, and methods of using the same for delivery of nucleic acids to a cell or a subject. The modifications provide a novel Rep-ITR interaction that limits vector mobilization, increasing the safety of viral vectors.
    Type: Grant

    Date of Patent: March 26, 2024
    Assignee: The University of North Carolina at Chapel Hill

  • Patent number: 11920127
    Abstract: Non-destructive methods and devices are disclosed herein for overcoming the limitations associated with analyzing shell casings and other cylindrical items for biomolecular and fingerprint extraction and analysis. In a preferred embodiment of these methodologies and devices, the open end of a spent shell casing (or like object) is plugged with a handle. This approach reduces the risk of sample contamination by gunpowder residue, while also providing a convenient means for handling the shell casing that reduces the risk of contamination or sample loss. Spin baskets (or extraction tubes) are provided which may be customized to different shell casing diameters, thereby substantially reducing the volume of extraction buffer required for sample collection and enable ease of centrifugation. A strong surfactant is preferably utilized during collection, which may reduce the amount of time needed for collection to just minutes.
