Wichita, Kan. and Collierville, Tenn. — Koch Agronomic Services LLC (KAS), a subsidiary of Koch Fertilizer LLC and Helena Chemical Co. said Jan. 8 that litigation between the two companies over intellectual property rights has been settled. Helena will continue to market both its N-FIXX™ nitrogen stabilizer brands, as well as KAS’s Agrotain ® nitrogen stabilizers. The parties said they look forward to future collaboration on products and services, and believe that joint efforts between the companies will provide value to all users of nitrogen stabilizer products. While the parties did not immediately disclose further details of the litigation and terms of the settlement, Koch filed suit against Helena July 26, 2012, in U.S. District Court for the Eastern District of Texas, Tyler Division, citing patent infringement. Koch raised its concerns with Helena in January 2012. It later amended its complaint March 28, 2013, saying Helena introduced a new infringing product, N-FIXX™ PF, after the first complaint was filed. Koch alleged Helena developed its N-FIXX by copying one or more of Koch’s Agrotain products with knowledge that it was patented. The District Court referred the matter to a mediator May 21, 2013. In December, the Court granted a joint motion to dismiss.
