FMC Corporation announced it has initiated litigation against Summit Agro LLC and Summit North American Holdings Corporation in United States District Court in Wilmington, Del., seeking injunctive and monetary relief for Summit’s infringement of an FMC patent covering production of FMC’s sulfentrazone herbicide, which is marketed in the United States under the Spartan and Authority brands. The complaint also alleges that Summit has engaged in unfair competition.

“FMC has invested significantly in developing sulfentrazone and associated production technology, as well as in establishing the strong reputation of Spartan and Authority brands in the minds of our customers,” said Marc Hullebroeck, North America and EMEA vice president and business director, FMC Agricultural Solutions. “FMC will vigorously defend its intellectual property rights.”

In 2012, FMC had annual sales of approximately $3.4 billion. The company employs approximately 6,000 people throughout the world, and operates its businesses in three segments: FMC Agricultural Solutions, FMC Health and Nutrition and FMC Minerals. 

Summit Agro USA, LLC has its office at Cary, N.C. Records show the company was formed under Delaware law in the spring of 2011. Summit Agro International Ltd. is 100 percent owned by Sumitomo Corporation with its head office in Tokyo, Japan.
