Continental Paper Bag Co. v. Eastern Paper Bag Co., 210 U.S. 405 (1908), was a case in which the Supreme Court of the United States established the principle that patent holders have no obligation to use their patent.[1]


Eastern Paper Bag brought an action to prevent its competitor Continental Paper Bag from using its patent for a "self-opening" paper bag. Continental Paper Bag alleged that Eastern Paper Bag was not using its patent but simply trying to suppress competition.

Decision of the Supreme Court[edit]

The Supreme Court rejected this argument by Continental Paper Bag, holding that it was the essence of the patent to exclude others without question of motive.
