On September 21, the Federal Circuit handed down its most recent Monsanto patent-related decision, Monsanto Company v. Bowman, reaffirming the company’s intellectual property rights and its licensing and enforcement strategies. This post provides some context for, and a discussion of, the issues raised in this case.
Monsanto invented the herbicide glyphosate in the 1970s (see U.S. Patent #3,799,758) and began selling it under the trade name Roundup in 1973. Roundup enjoyed great commercial success and is still widely used today. Monsanto later invented technology which allowed them to create genetically altered seeds that would grow into plants resistant to glyphosate. These genetically altered seeds, marketed as “Roundup Ready,” have similarly enjoyed great commercial success. Monsanto patents (see, e.g., U.S. Patent #5,352,605) cover the genetically modified seeds, which pass on their glyphosate-resistive properties to subsequent seed generations.
The licensing agreements under which Monsanto commercializes their Roundup Ready seed technology have generally prohibited, among other things, transfer or re-use of genetically altered seed for replanting, effectively requiring that every farmer wanting to plant Roundup Ready seed must, every season, go back to Monsanto to purchase additional seed. This policy has angered many farmers who have traditionally kept seed grown in one season to plant in the next, or purchased seed in bulk from other sources.
Monsanto has disclosed that since 1997 it has filed suit against 145 farmers for patent infringement and proceeded through trial against eleven. A handful of these cases have become high profile patent suits. Continue reading
