Patents by Inventor Masahisa Takatsu

Masahisa Takatsu 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).

  • Polymer for detecting fingerprint, method of producing the same, composition for detecting fingerprint and method of detecting fingerprint using the same
    Patent number: 8268919
    Abstract: It is intended to provide a polymer for detecting a fingerprint, which can be easily handled in a scene of the fingerprint detection as a substitute for conventionally employed 2-cyanoacrylate (a monomer), and a composition for detecting a fingerprint. It is also intended to provide a method of detecting a fingerprint whereby a fingerprint can be detected at a high sensitivity regardless of the color or conditions of a specimen and wherein the specimen can be well restored. The present polymer and composition for detecting a fingerprint and method of detecting a fingerprint using the same make it possible to definitely detect a fingerprint by using fluorescence even from an almost white specimen such as a shopping bag or an aluminum foil from which a fingerprint can be hardly detected by the existing methods.
