Patents by Inventor Ian Jepson

Ian Jepson 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).

  • Plant-derived enzyme and DNA sequences and uses thereof
    Patent number: 5866792
    Abstract: The chemically-inducible 27 kD subunit of the enzyme glutathione-S-transferase, isoform II (GST-II-27) and sequences encoding it are provided. In particular, a genomic DNA sequence encoding the gene promoter for the GST-II-27 subunit is provided. Then linked to an exogenous gene and introduced into a plant by transformation, and GST-II-27 promoter provides a means for the external regulation of expression of that exogenous gene. Transformation with DNA encoding glutathione-S-transferase polypeptides produces herbicide resistance transgenic plants.
    Type: Grant
    Filed: June 17, 1996
    Date of Patent: February 2, 1999
    Assignee: Zeneca Limited
    Inventors: Ian George Bridges, Simon William Jonathan Bright, Andrew James Greenland, David Charles Holt, Ian Jepson, Wolfgang Walter Schuch
