Russell Dean Birkholz 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).

  • Large area organic electronic devices having conducting polymer buffer layers and methods of making same
    Publication number: 20030209973
    Abstract: Large area organic electronic devices having a doped conducting polymer buffer layer are described. Methods for applying a doped conducting polymer buffer layer to an electrode-coated large area substrate are described. The methods include web coating techniques such as microgravure coating or meniscus coating, which may be used in continuous coating processes.
    Type: Application
