DuPont says it has settled a patent infringement lawsuit it filed earlier this year against Jiangsu Trustchem Chemicals in China.

"DuPont aggressively protects its intellectual property and will enforce its rights to prevent counterfeiting of its product, infringement of its patents and trademarks, theft of its trade secrets and other illegal activities," said Glen Baldwin, lead counsel for DuPont Crop Protection.

Under the terms of the settlement, Trustchem will reportedly pay monetary compensation and make a public apology to DuPont for losses resulting from Trustchem actions. Financial terms of the agreement were not disclosed.

DuPont initiated the lawsuit in the Nanjing in March in response to illegal Trustchem sales of agricultural products containing rimsulfuron, which are protected by a DuPont patent in China. Rimsulfuron is an active ingredient in crop protection herbicides that are marketed around the world under the Titus, Matrix and Resolve trademarks.

This lawsuit represents part of an ongoing DuPont Crop Protection program to protect its intellectual property rights worldwide. Based on these investigations, DuPont says it has filed similar patent infringement actions against several other companies, issued numerous "cease and desist" letters and is actively investigating several other businesses in China that are suspected of violating DuPont patents.
