U.S. Water Servs., Inc. v. ChemTreat, Inc.
In April 2011, while its patent application was pending with the USPTO, U.S. Water Services, which “sell[s] water treatment and purification equipment, materials, and services,” especially “to ethanol process technologies,” sued its competitor, ChemTreat, for misappropriation of trade secrets. In October 2011, the USPTO issued the 244 patent covering a method to reduce the formation of insoluble scale deposits during the production of ethanol using enzyme, phytase, in its “pHytOUT® system.”Three days before U.S. Water and ChemTreat settled the misappropriation claim, ChemTreat filed counterclaims requesting declaratory judgments of noninfringement and invalidity of the 244 patent. The suit was filed before the Leahy-Smith America Invents Act, 125 Stat. 284, took effect, so the counterclaims independently did not establish appellate jurisdiction for the Federal Circuit. The district court granted ChemTreat summary judgment as to the noninfringement counterclaim and dismissed the invalidity counterclaim. The Eighth Circuit affirmed. Evaluating the “totality of [the] circumstances,” the district court did not err in finding the misappropriation action, together with U.S. Water’s statements to its customers and supplier, produced an objective, “reasonable apprehension of suit,” and did not err in concluding declaratory judgment subject matter jurisdiction existed. The decision did not constitute an advisory opinion. View "U.S. Water Servs., Inc. v. ChemTreat, Inc." on Justia Law
