Matthias Liebergesell 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).

  • Genes from chromatium vinosum for the production of polyhydroxyalkanoate
    Patent number: 6515205
    Abstract: Genes encoding polyhydroxyalkanoate synthase, &bgr;-ketothiolase and acetoacetyl CoA reductase are isolated from the publicly available bacterium Chromatium vinosum. Recombinant genomes of plants or other species of bacteria which contain these genes are capable of producing polyalkanoate polymers. The nucleotide sequences of the said three genees have been determined.
    Type: Grant
