Patents by Inventor William Ratcliffe

William Ratcliffe 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).

  • Publication number: 20080030133
    Abstract: Light-emitting structures of reduced size are realized with combinations of light-emitting diodes, resistive and conductive films, and interconnect members. Other embodiments are provided which simplify fabrication and assembly.
    Type: Application
    Filed: October 8, 2007
    Publication date: February 7, 2008
    Inventor: William Ratcliffe
  • Publication number: 20060250793
    Abstract: Light display structures are provided that are simple and comprise few parts so that they can be economically fabricated from various polymers and quickly assembled. They are especially suited for carrying light-emitting elements and lend themselves for realization in a variety of forms such as elongate display structures and sheet-like display structures. They are based upon a plurality of light-emitting elements (e.g., light-emitting diodes) that are coupled between first and second conductors with the addition of other structures (e.g., spacers, wire bonds, tabs) that facilitate the energizing of the light-emitting elements.

  • Publication number: 20060245191
    Abstract: Useful light display structures are configured so that they can be economically fabricated and assembled. The light display structures generally comprise a plurality of light-emitting elements that are coupled between first and second conductors with the addition of other structures (e.g., spacers, light redirectors, substrates, wire bonds, tabs, posts, ground planes and blocks) that support or augment the conductors.
