United States v. E. I. du Pont de Nemours & Co.

United States Supreme Court
351 U.S. 377 (1956)


Facts

E. I. du Pont de Nemours & Company (du Pont) (defendant) produced 75 percent of the cellophane sold in the United States. Cellophane sales comprised 17.9 percent of all sales of “flexible packaging materials” in the United States. Other flexible packaging materials included aluminum foil and Saran wrap. The United States government (plaintiff) brought suit against du Pont, alleging that du Pont’s market share of cellophane constituted an illegal monopoly under § 2 of the Sherman Act. The trial court found in favor of du Pont. The United States Supreme Court granted certiorari.
