DuPont Asserts Anti-Trust, Patent Claims Against Monsanto

DuPont Affirms 'Stacking' Can Occur Under Existing Monsanto License Agreement

ST. LOUIS, June 16 /PRNewswire/ -- DuPont (NYSE: DD) today filed an answer and
counterclaims to a recent Monsanto lawsuit that seeks to block farmers' access
to innovative new soybean lines from DuPont business Pioneer-Hi Bred. These
soybeans would contain Pioneer's proprietary Optimum(R) GAT(R) trait and --
through Monsanto's royalty-bearing license agreement -- the Roundup Ready(R)
trait.

In its federal court filing here today, DuPont affirmed that combining, or
"stacking," of Optimum(R) GAT(R) and Roundup Ready(R) technologies is clearly
within its rights under the license agreement with Monsanto. DuPont also said
that patents relating to Monsanto's Roundup Ready(R) soybeans are invalid and,
therefore, are not infringed when Optimum(R) GAT(R) and Roundup Ready(R)
traits are "stacked" in soybeans. In addition, DuPont is seeking broad relief
under anti-trust laws that would end Monsanto's multifaceted, anti-competitive
scheme to unlawfully restrict competition.

"We believe we have every right through our existing Monsanto license
agreement to 'stack' our Optimum(R) GAT(R) trait with Pioneer soybean genetics
already containing a Roundup Ready(R) trait," said DuPont Group Vice President
James C. Borel. "We will vigorously defend our rights to bring valuable new
technologies to the market.

"Monsanto's lawsuit is another tactic used to restrict the availability of
competitive products. Farmers want and deserve diverse technology options
that can best satisfy their specific needs to help meet the increasing global
demands for agriculture. Advancements in agriculture productivity, for
example, hinge on having technology options available in the market. Our
proprietary Optimum(R) GAT(R) trait combined with the Roundup Ready(R) trait
in elite Pioneer soybean genetics would be superior to any other product on
the market -- better yields and broader, more flexible weed control options,"
Borel added. "The seed industry, U.S. growers, and, ultimately, consumers are
best served when seed companies can assemble the best combinations of traits
and germplasm for their customers -- without the anti-competitive restrictions
imposed by Monsanto."
