ST. LOUIS - Syngenta AG is promising to appeal a federal jury ruling favoring agribusiness rivals Monsanto Co. and a Dow Chemical Co. biotechnology subsidiary in a patent-infringement flap over insect-resistant corn.
U.S. District Court jurors in Delaware determined Tuesday that Monsanto and Indianapolis-based Dow AgroSciences did not infringe on a Syngenta patent, essentially finding the patent invalid because Switzerland-based Syngenta did not actually invent the technology.
