Stephan Schoft 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).

  • Layered electrically conductive material
    Patent number: 7880582
    Abstract: An electrical resistor has an electrically conductive stack, which includes a plurality of metal first layers and second layers. The stack allows to produce a highly anisotropic resistor, in which the resistance in the direction perpendicular to the layers is much higher than in the plane of the layers. The anisotropy allows the current flowing through the stack to be made homogenous, e.g., to be distributed over the entire stack surface, even if the current is input into the stack in an inhomogenous manner.
    Type: Grant
    Filed: April 7, 2009
    Date of Patent: February 1, 2011
    Assignee: ABB Research Ltd
    Inventors: Jens Tepper, Friedrich Koenig, Kaveh Niayesh, Stephan Schoft
