Sophie Dufour 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).

  • Identification of biological (micro) organisms by detection of their homologous nucleotide sequences on arrays
    Patent number: 7205104
    Abstract: A method for identifying or quantifying an organism by a detecting its nucleotide sequence among at least 4 other homologous sequences comprising amplifying nucleic acids from the organism to generate target nucleotide sequences to be detected; contacting the target nucleotide sequences with single stranded capture nucleotide sequences bound by a single predetermined link to an insoluble solid support and discriminating the binding of a target nucleotide sequence specific of an organism with a signal resulting from a hybridization by complementary base pairing between the target nucleotide sequence and its corresponding capture nucleotide sequence is disclosed. The capture nucleotide sequence is bound to the insoluble solid support at a specific location on an array having a density of at least 4 different bound single stranded capture nucleotide sequences/cm2. The location of the signal on the array allows identification or quantification of the organism.

  • Identification of a large number of biological (micro)organisms groups at different levels by their detection on a same array
    Patent number: 7202026
    Abstract: The present invention is related to an identification and/or quantification method of a large number of biological organisms groups at different levels (family, genus, species) or part of those (possibly present in a biological sample) by a detection of their nucleotide sequence.
