FMC Sues Summit Agro for Patent Infringement, Unfair Competition

FMC Corp. said it filed a lawsuit on Friday today against Summit Agro LLC and Summit North American Holdings Corp., alleging patent infringement of its sulfentrazone herbicide, which is sold in the United States under the Spartan and Authority brands.

The complaint, filed in the United States District Court in Wilmington, Delaware, also alleges that Summit Agro, which is a trading company of Japan-based Sumitomo Corp., 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.”

A response to an inquiry made by Farm Chemicals International to Sumitomo Corp. regarding the litigation was not immediately available.
