Patents by Inventor Johannes Joseph Wilhelmus de Haard

Johannes Joseph Wilhelmus de Haard 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: 11827701
    Abstract: The present invention provides binding molecules (e.g., antibodies or antigen binding fragments thereof) that specifically bind to and inhibit the biological activity of IL-6 (e.g., human, mouse and non-human primate IL-6). In a preferred embodiment, the antibodies or antigen binding fragments of the invention bind to IL-6 and inhibit its binding to an IL-6 receptor. Such antibodies or antigen binding fragments are particularly useful for treating IL-6-associated diseases or disorders (e.g., inflammatory disease and cancer).

  • Patent number: 11649295
    Abstract: The present invention relates to multispecific antibodies, for example bispecific antibodies, and methods for the isolation or purification of the same. The antibodies of the invention comprise first and second heavy chain-light chain pairings wherein each pairing comprises a distinct selective recognition site including one or more amino acid residues contributed from the heavy chain and the light chain of the pairing. The first and second selective recognition sites differ by at least one amino acid residue and can be differentially bound by first and second selective recognition agents according to the methods of the invention. Such methods facilitate the production of antibody preparations enriched for multispecific antibodies having the correct functional heavy chain-light chain pairings.

  • Patent number: 11479879
    Abstract: A triple expression vector is disclosed for expressing an antibody molecule comprising an Fc domain in prokaryotic cells and in eukaryotic cells. The triple expression vector comprises a polynucleotide encoding an Fc domain; a polynucleotide encoding a phage coat protein; a cloning site for cloning genes encoding an antibody molecule or a part thereof wherein the antibody molecule or part thereof does not comprise an Fc domain; a prokaryotic secretion signal sequence and a eukaryotic secretion signal sequence, or a secretion signal sequence that drives efficient secretion in both prokaryotic and eukaryotic cells; a promoter for mediating expression in eukaryotic cells; and a stop codon for preventing expression of the phage coat protein in eukaryotic cells.

  • Patent number: 10040870
    Abstract: Disclosed is an immune library obtained from a Camelid species containing at antibody chains belonging to at least 7 human germline antibody chains. The presence of a large number of human germline antibody chain families in the library contributes to the usefulness of the library in producing antibodies to human target antigens. The antibodies produced from the library have low inherent immunogenicity.

  • Patent number: 9926364
    Abstract: Provided are chimeric, camelid-human (e.g., llama-human) polypeptides comprising a first antigenic polypeptide portion and a second antigenic polypeptide portion wherein the first antigenic portion is a derived from a first portion of a camelid (e.g., llama) and the second antigenic portion is a human polypeptide homolog of a second portion of the camedid antigen. The chimeric polypeptides are useful inter alia for epitope mapping and generation of antibodies that bind to a desired region of human antigen.
