David A. Patton 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).

  • Herbicide target genes and methods
    Publication number: 20020127537
    Abstract: The invention relates to genes isolated from Arabidopsis that code for proteins essential for normal plant development. The invention also includes the methods of using these proteins to discover new herbicides, based on the essentiality of the genes for normal growth and development. The invention can also be used in a screening assay to identify inhibitors that are potential herbicides. The invention is also applied to the development of herbicide tolerant plants, plant tissues, plant seeds, and plant cells.

  • Transgenic plants having increased biotin content
    Patent number: 5869719
    Abstract: The present invention reveals that biotin biosynthesis in a plant is enhanced when the level of one or more of the enzymes in the plant biotin biosynthetic pathway is increased. Based upon this revelation, methods that increase the level of one or more biotin biosynthetic enzymes in plant tissue are provided as a means for achieving enhanced levels of biotin in plant tissue. In particular, a method is provided for enhancing biotin levels by introducing into plant tissue a chimeric gene capable of expressing a biotin biosynthetic enzyme such as biotin synthase. Thus, transgenic plant tissue, including whole plants, having enhanced levels of biotin is likewise provided.

  • Flashlight holder
    Patent number: 4907769
    Abstract: A flashlight holder includes a C-shaped clamp that holds a flashlight by friction. The clamp is attached by an angled arm to a tripod that supports the arm in a fixed position of choice. Magnet assemblies in the legs of the tripod are mounted so as to swivel, allowing the flashlight holder to be secured by magnetic force to a ferromagnetic surface. The flashlight holder is preferably made of low-density polypropylene, which is both inexpensive to buy and easy to mold in molds that require little or no relief. The angled arm makes it easy to set a flashlight at any orientation with respect to an iron or steel surface to provide light to work on car and truck engines and the like.
