Patents by Inventor John Schenk

John Schenk 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: 7629113
    Abstract: Improved insemination systems particularly adapted to use for sex-selected sperm sorting include systems which achieve superovulation and then multiple embryo production with sexed embryos. These systems combine with other techniques, including techniques for enhanced sheath fluid and other strategies which minimize stress on the sperm cells, and, potentially, a 2.9 percent sodium citrate sheath solution for bovine species and a hepes bovine gamete media for equine species. Improved collection systems and techniques for the process are described so that commercial application of sperms samples as well as the resulting animals may be achieved.

  • Publication number: 20070099171
    Abstract: The present invention provides a method of cryopreserving sperm that have been selected for a specific characteristic. In a preferred embodiment, the method is employed to freeze sex-selected sperm. Although the cryopreservation method of the invention can be used to freeze sperm selected by any number of selection methods, selection using flow cytometry is preferred. The present invention also provides a frozen sperm sample that has been selected for a particular characteristic, such as sex-type. In preferred embodiments, the frozen sperm sample includes mammalian sperm, such as, for example, human, bovine, equine, porcine, ovine, elk, or bison sperm. The frozen selected sperm sample can be used in a variety of applications. In particular, the sample can be thawed and used for fertilization. Accordingly, the invention also includes a method of using the frozen selected sperm sample for artificial insemination or in vitro fertilization.

  • Publication number: 20070026378
    Abstract: The inventive technology relates to methods and apparatus for reducing protein content in sperm cell extenders and may include one or more of the following features: techniques for reducing protein content in a sperm cell extender; techniques for reducing protein content in a cryoprotectant-containing B fraction of a sperm cell extender; techniques for preparing sperm cell extenders that do not require clarification; techniques for preparing low density gradient sperm cell extenders suitable for centrifugation; techniques for reducing protein content between individual steps in preparing a sperm cell extender, and techniques for establishing novel values of reduced protein content in sperm cell extenders.
