Deb Narayan Chakravarti 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).

  • Publication number: 20130011428
    Abstract: The present invention relates to newly identified open reading frames comprised within the genomic nucleotide sequence of Streptococcus pneumoniae, wherein the open reading frames encode polypeptides that are surface localized on Streptococcus pneumoniae. Thus, the invention relates to Streptococcus pneumoniae open reading frames that encode polypeptides encoded by the Streptococcus pneumoniae open reading frames, vectors comprising open reading frame sequences and cells or animals transformed with these vectors. The invention relates also to methods of detecting these nucleic acids or polypeptides and kits for diagnosing Streptococcus pneumoniae infection. The invention finally relates to pharmaceutical compositions, in particular immunogenic compositions, for the prevention and/or treatment of bacterial infection, in particular infections with Streptococcus pneumoniae.
    Type: Application

  • Patent number: 8241642
    Abstract: The present invention relates to newly identified open reading frames comprised within the genomic nucleotide sequence of Streptococcus pneumoniae, wherein the open reading frames encode polypeptides that are surface localized on Streptococcus pneumoniae. Thus, the invention relates to Streptococcus pneumoniae open reading frames that encode polypeptide antigens, polypeptides, preferably antigenic polypeptides, encoded by the Streptococcus pneumoniae open reading frames, vectors comprising open reading frame sequences and cells or animals transformed with these vectors. The invention relates also to methods of detecting these nucleic acids or polypeptides and kits for diagnosing Streptococcus pneumoniae infection. The invention finally relates to pharmaceutical compositions, in particular immunogenic compositions, for the prevention and/or treatment of bacterial infection, in particular infections with Streptococcus pneumoniae.
