Lee A. Donohue 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).

  • Methods of packaging thin metal films to maintain their physical characteristics
    Patent number: 11472582
    Abstract: The present disclosure is directed to the packaging of metal thin films deposited on polymeric substrates. The packaging method prevents deleterious change of surface energy/water contact angle as a function of time for metal thin films such as rolls, coils, sheets or strips of sputtered or vacuum deposited metal thin films. Methods and kits directed toward a unique packaging and storage scheme are also disclosed. This results in maintenance of the metal film's hydrophilicity and surface energy for extended periods of time.
    Type: Grant
    Filed: April 30, 2021
    Date of Patent: October 18, 2022
    Assignee: Materion Corporation
    Inventors: Lee A. Donohue, Margaret S. Fariss, Christopher Massing, Robert R. Newton, Kevin V. Goodwin
  • Methods for stabilizing palladium films
    Patent number: 11371956
    Abstract: The present disclosure relates to methods of creating a biosensor. A palladium film is deposited onto a surface of a substrate. The palladium film is then treated with an air plasma to stabilize the palladium and reduce or eliminate its catalytic activity. The biosensor is created from the treated palladium film and the substrate.
    Type: Grant
