Patents by Inventor James Casbon

James Casbon 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: 10626441
    Abstract: Described herein is a method for adding a counter sequence to the individual polynucleotide molecules of an initial nucleic acid sample. After addition of the counter sequence, the sample may be amplified and the number of initial target molecules in the sample can be estimated by counting the number of counter sequences associated with the amplified target molecules.
    Type: Grant
    Filed: April 27, 2017
    Date of Patent: April 21, 2020
    Assignee: Agilent Technologies, Inc.
    Inventors: Robert Osborne, James Casbon, Andreas Claas, Gi Mikawa, Esther Musgrave-Brown

  • Patent number: 9670536
    Abstract: Aspects of the present invention include methods and compositions for determining the number of individual polynucleotide molecules originating from the same genomic region of the same original sample that have been sequenced in a particular sequence analysis configuration or process. In these aspects of the invention, a degenerate base region (DBR) is attached to the starting polynucleotide molecules that are subsequently sequenced (e.g., after certain process steps are performed, e.g., amplification and/or enrichment). The number of different DBR sequences present in a sequencing run can be used to determine/estimate the number of different starting polynucleotides that have been sequenced. DBRs can be used to enhance numerous different nucleic acid sequence analysis applications, including allowing higher confidence allele call determinations in genotyping applications.
