Patents by Inventor Chi-Yu Gregory Lee

Chi-Yu Gregory Lee 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: 11447562
    Abstract: A chimeric antigen receptor (CAR) having an antigen binding domain capable of binding to CA215. The antigen binding domain can have a binding affinity and specificity similar to the RP215 antibody. Methods of making and using such CARs are provided. The CARs can be used to treat cancer.
    Type: Grant
    Filed: December 22, 2017
    Date of Patent: September 20, 2022
    Inventor: Chi-Yu Gregory Lee

  • Publication number: 20130195873
    Abstract: Immunogenic compositions that contain haptens consisting of carbohydrate moieties are useful to induce an immune response to provide antibodies to epitopes contained in CA215 and also to elicit an immune response to cancers expressing these epitopes.

  • Patent number: 8361793
    Abstract: Monoclonal antibodies against gonadotropin releasing hormone (GnRH) receptor induce cellular apoptosis of various cancer cells expressing this surface receptor. The monoclonal antibodies and their humanized forms, or fragments thereof, can serve as anti-cancer agents for the treatment of cancer in humans, and can function as analogs of GnRH to affect regulation of reproductive functions or fertility in humans.

  • Publication number: 20120177636
    Abstract: The effective epitope of CA215, a known cancer marker and antigen, has been demonstrated to include a carbohydrate moiety of defined composition and to be non-reactive with anti-human IgG, IgA and IgM, although CA215 is an immunoglobulin heavy chain-like molecule. The defined epitope may be used to prepare immunogenic compositions for treatment and prevention of cancers in humans and may be optimized as to protocol and formulation in animal model systems. Improved protocols for diagnosis and treatment are also described.
