Kang In Na 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).

  • Patent number: 7645450
    Abstract: Humanized antibodies specifically binding to hTNF-? are prepared from a mouse monoclonal antibody by the CDR (complementarity determining region) grafting method, and they show an antigen binding affinity similar to the original mouse monoclonal antibody and significantly low immunogenicity. Therefore, the humanized antibodies can be effectively used for treating a hTNF-?-related disease such as rheumatoid arthritis, Crohn's disease, psoriatic arthritis, psoriasis, septicemia, asthma, Wegener's granulomatosis, inflammation, and ankylosing spondylitis.
    Type: Grant
    Filed: December 29, 2005
    Date of Patent: January 12, 2010
    Assignee: Yuhan Corporation
    Inventors: Tae Hyoung Yoo, Moo Young Song, Chang Seok Kim, Sang Koo Park, Kang In Na, Byung Kyu Lee, Heui Il Kang
  • Patent number: 7435414
    Abstract: A humanized antibody of the present invention shows similar antigen-binding affinity to a mouse monoclonal antibody and significantly low immunogenecity. Therefore, the humanized antibody of the present invention can be effectively used for treating chronic hepatitis B and preventing HBV infection of a patient received liver transplantation and vertical transmission from a mother infected with HBV to a fetus.

  • Patent number: 7196177
    Abstract: An antibody variable region of a monoclonal antibody specifically binding to human tumor necrosis factor-? contains at least one of a heavy chain variable region and a light chain variable region having specific complementarity determining regions therein. A nucleic acid molecule encoding the same, a recombinant vector containing the nucleic acid molecule, and a cell transformed with the recombinant vector are also provided.
