Ronald Hitzeman 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).

  • Automatic eukaryotic artificial chromosome vector
    Publication number: 20050019924
    Abstract: The present invention is directed to novel recombinant nucleic acids for introducing yeast chromosomal elements into the genomes of bacteria. The invention provides methods to convert the modified bacterial genomes into artificial yeast chromosomes by fusing the bacteria with yeast that linearize the modified bacterial genomes, to produce artificial chromosomes.
    Type: Application

  • Monolithic structure with redundant load paths
    Patent number: 6443392
    Abstract: A monolithic structure for use as a pressure bulkhead for an aircraft includes a first web, a redundant second web spaced from the first web, stiffeners disposed between and connecting the webs to each other, and first and second outer attachment rings respectively provided on the outer peripheries of the first and second webs for attaching the bulkhead to fuselage structure. One of the webs comprises a pressure web for supporting pressure loading, and the other web defines at least one aperture therethrough. The stiffeners are integrally fabricated along with at least one of the webs and associated attachment ring as a one-piece monolithic part.

  • Eukaryotic vectors and plasmids having PGK regulatory signals
    Patent number: 4865989
    Abstract: Novel compositions and methods employing the compositions are provided involving eukaryotic plasmids having a replication system or replicon from an extrachromosomal element, a chromosomal replicator, and the regulatory signals of the structural gene for yeast 3-phosphoglycerokinase controlling expression of a structural gene. The plasmids find particular use in yeast for production of poly(amino acids).
