Natalia T. Sokoluk 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).

  • Photo-chemical generation of stable fluorescent derivatives of rhodamine B
    Patent number: 6280904
    Abstract: The present invention relates to the field of optical recording materials, in particular, fluorescent compounds and matrices suitable for use in optical memory systems, including three dimensional optical memory systems for READ ONLY MEMORY (ROM). In particular, nonfluorescent Rhodamine B lactams are photochemically transformed into fluorescent Rhodamine B derivatives.
    Type: Grant
    Filed: February 17, 2000
    Date of Patent: August 28, 2001
    Assignee: Tridstore IP, LLC
    Inventors: Natalia T. Sokoluk, Vladimir V. Shubin, Eugene B. Levich, Jacob N. Malkin

  • Photochemical generation of stable fluorescent amines from peri-phenoxiderivatives of polycyclic P-quinones
    Patent number: 5945252
    Abstract: The present invention relates to the field of optical recording materials, in particular, fluorescent compounds and matrices suitable for use in optical memory systems, including three dimensional optical memory systems for READ ONLY MEMORY (ROM). More particularly, nonfluorescent peri-phenoxiderivatives of polycyclic quinones are transformed into fluorescent aminoderivatives of anaquinones.
