(Reuters) - A federal judge has ruled in favor of global seed giant Monsanto Co, dismissing a lawsuit brought by a consortium of U.S. organic farmers and seed dealers who said their industry is at risk from Monsanto's growing market strength.

U.S. District Court Judge Naomi Buchwald, for the Southern District of New York, threw out the case brought by the Organic Seed Growers and Trade Association (OSGATA) and dozens of other plaintiff growers and organizations, criticizing the groups for a "transparent effort to create a controversy where none exists."

The Public Patent Foundation (PUBPAT) filed the suit last March on behalf of more than 50 organizations challenging the agricultural giant's patents on its genetically modified seeds. The group wanted a ruling that would prohibit Monsanto from suing the farmers or dealers if their organic seed becomes contaminated with Monsanto's patented biotech seed germplasm.

But Judge Buchwald said Monsanto had not sued or even started the process of suing anyone of the plaintiffs or anyone in "similar stead."
