The Copyright Act of 1790 did not provide a formal definition of infringement, stating only that “any person or persons who shall print or publish any manuscript, without the consent and approbation of the author or proprietor thereof... shall be liable to suffer and pay to the said author or proprietor all damages occasioned by such injury.” Furthermore, the Copyright Act of 1909 simply provided that any person who “shall infringe the copyright in any work protected under the copyright laws of the United States… shall be liable” for various remedies.
