Michael Felder 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).

  • Topoisomerase linker-mediated amplification methods
    Patent number: 7078501
    Abstract: A Vaccinia topoisomerase-adapted linker, which contains an oligonucleotide primer binding site of known sequence, useful for specifically joining the linker to the end of a polynucleotide of unknown sequence and allowing subsequent PCR amplification of the polynucleotide or DNA is provided. Kits containing the invention Vaccinia topoisomerase-adapted linker and one or more linker-specific oligonucleotides for annealing to the linker in PCR are also provided. In addition, the invention provides methods for using the invention linkers in linker-mediated PCR amplification procedures for isolation and optional sequencing of isolated PCR amplification products.
    Type: Grant
    Filed: February 23, 2001
    Date of Patent: July 18, 2006
    Assignees: Invitrogen Corporation, South Carolina Research Institute
    Inventors: John A. Heyman, Gabor Szalai, Michael Felder, Knut R. Madden
