Georges L. Freyssinet 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).

  • Production of .gamma.-linolenic acid by a .DELTA.6-desaturase
    Patent number: 5789220
    Abstract: Linoleic acid is converted into .gamma.-linolenic acid by the enzyme .DELTA.6-desaturase. The present invention is directed to isolated nucleic acids comprising the .DELTA.6-desaturase gene. More particularly, the isolated nucleic acid comprises the promoter, coding region and termination regions of the .DELTA.6-desaturase gene. The present invention provides recombinant constructions comprising the .DELTA.6-desaturase coding region in functional combination with heterologous regulatory sequences. The nucleic acids and recombinant constructions of the instant invention are useful in the production of GLA in transgenic organisms.
    Type: Grant
    Filed: January 28, 1997
    Date of Patent: August 4, 1998
    Assignee: Rhone-Poulenc Agrochimie
    Inventors: Terry L. Thomas, Avutu S. Reddy, Michael Nuccio, Andrew N. Nunberg, Georges L. Freyssinet
