David O. Willer 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).

  • DNA JOINING METHOD
    Publication number: 20110143399
    Abstract: The present invention provides a method to directionally clone any linear template DNA molecule into any linearized vector. The vector ends may be generated from any restriction enzyme cleavage. The method does not require a ligation step nor the use of carefully controlled conditions as is required with methods involving specific exonucleases alone. It has been determined that specific DNA polymerases are able to efficiently join one or more linear DNA molecules sharing ends with appropriate complementation.
    Type: Application
