DuPont settles lawsuit

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

Under the terms of the settlement, Trustchem will 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, Jiangsu Province 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 is said to represent part of an ongoing DuPont Crop Protection program to protect its intellectual property rights worldwide. Based on these investigations, DuPont has filed similar patent infringement actions against several other companies, issued numerous "cease and desist" letters and is investigating several other businesses in China that are suspected of violating DuPont patents.
