Patents by Inventor Christian Leutenegger

Christian Leutenegger 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).

  • Nucleic acid amplification controls and kits and methods of use thereof
    Patent number: 11725242
    Abstract: The invention provides components and methods for polymerase chain reaction assays. The assays minimize both handling of material and time spent running samples. For example, a single internal positive control (IPC) polynucleotide pair can provide a means to ensure proper nucleic acid purification for both RNA and DNA test targets. Additionally, standard cycling conditions for all diagnostic tests allow the user to run both RNA and DNA targets side-by-side.
    Type: Grant
    Filed: December 20, 2018
    Date of Patent: August 15, 2023
    Assignee: IDEXX Laboratories, Inc.
    Inventors: Christian Leutenegger, Michael John Angelichio

  • Nucleic acid amplification controls and kits and methods of use thereof
    Patent number: 10174373
    Abstract: The invention provides components and methods for polymerase chain reaction assays. The assays minimize both handling of material and time spent running samples. For example, a single internal positive control (SPC) polynucleotide pair can provide a means to ensure proper nucleic acid purification for both RNA and DNA test targets. Additionally, standard cycling conditions for ali diagnostic tests allow the user to run both RNA and DNA targets side-by-side.

  • Feline interleukin-12 as immunostimulant
    Publication number: 20030157059
    Abstract: The use of feline interleukin-12 (IL-12) is described as an adjuvant (or immunostimulant) and in the vaccination and therapy of infectious diseases in Felidae. In addition, a procedure is disclosed which makes it possible to express the two subunits of IL-12 in the requisite mass ratio.
