TORONTO (ICIS news)--DuPont said on Wednesday it had settled a patent infringement lawsuit against a Chinese firm and would be compensated for its losses.


DuPont brought the case against Trustchem, also known as Jiangsu Trustchem Chemicals, in March, charging it with illegal sales of agricultural products containing rimsulfuron.


Rimsulfuron, an active ingredient in crop protection herbicides that are marketed around the world under the Titus, Matrix and Resolve trademarks, is protected by a DuPont patent in China, it said.


DuPont did not disclose the financial terms of its settlement with Trustchem.


The company added it had filed similar patent infringement actions against other companies, issued numerous "cease and desist" letters, and was investigating several other businesses in China that were suspected of violating its patents.
