Tatyana Ya. Dutova 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).

  • Anisotropic films based on 1,8-naphthoylene-1?,2?-benzimidazole sulfonates and lyotropic liquid crystal systems and methods for making
    Patent number: 7262305
    Abstract: Optically anisotropic films based on sulfoderivatives of 1,8-naphthoylene-1?,2?-benzimidazole are disclosed. These compounds form stable lyotropic liquid crystal systems that exhibit excellent optical properties with films that are significantly thinner that the current state of the art. The lyotropic liquid crystal systems may be deposited on substrates for use in a wide variety of commercial applications.
    Type: Grant
    Filed: August 25, 2005
    Date of Patent: August 28, 2007
    Assignee: Nitto Denko Corporation
    Inventors: Tatyana Ya. Dutova, Elena N. Sidorenko
