Venzie Corp. v. United States Mineral Products Co‪.‬

Plaintiffs, the Venzie Corporation and F. M. Venzie & Company, Inc., appeal from an order granting defendants motion for judgment n.o.v. on their claim of a concerted refusal to deal. In their complaint, plaintiffs asserted that defendants United States Mineral Products Company, Inc. ("Mineral") and William Armstrong & Sons, Inc. ("Armstrong") had by agreement refused to sell a fireproofing material to plaintiffs in violation of Section 1 of the Sherman Act. Plaintiffs also attack an order of the district court directing a verdict for defendants on their claim that defendants had illegally tied the sale of the fireproofing product of Mineral to the purchase of the application services of Armstrong.
