Nanae Kawate 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).

  • Norbornene-type formate monomers and polymers and optical waveguides formed therefrom
    Patent number: 8716421
    Abstract: This invention discloses and claims a series of polycyclic monomers and polymers useful in the production of optical waveguides. The polymers of the invention comprise one or more repeating units represented by the formula (IV): Wherein m, X, R1 and R2 are as defined herein. The films formed from the polymers of this invention exhibit significant changes in refractive index (greater than or equal to 0.5%) after exposure to suitable actinic or thermal energy thereby having superior optical transmission performance, which is of importance for modern optical applications such as wave guiding and optical data storage.
