Kevin Janssen 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).

  • Methods for the enrichment of mutated nucleic acid from a mixture
    Patent number: 9873908
    Abstract: The detection of the presence of rare somatic mutations from a biological sample is often challenging due to the simultaneous presence of a vast excess of wild-type DNA. The present invention describes methods that would allow the enrichment of mutant DNA by depleting amplifiable wild-type DNA.
    Type: Grant
    Filed: November 19, 2014
    Date of Patent: January 23, 2018
    Assignee: Roche Molecular Systems, Inc.
    Inventors: Amar Gupta, Nancy Schoenbrunner, Kevin Janssen
