Opinion of the Court
see generally Ochoa, Patent and Copyright Term Extension and the Constitution: A Historical Perspective, 49 J. Copyright Soc. 19 (2001). The courts saw no "limited Times" impediment to such extensions; renewed or extended terms were upheld in the early days, for example, by Chief Justice Marshall and Justice Story sitting as circuit justices. See Evans v. Jordan, 8 F. Cas. 872, 874 (No. 4,564) (CC Va. 1813) (Marshall, J.) ("Th[e] construction of the constitution which admits the renewal of a patent, is not controverted. A renewed patent . . . confers the same rights, with an original."), aff'd, 9 Cranch 199 (1815); Blanchard v. Sprague, 3 F. Cas. 648, 650 (No. 1,518) (CC Mass. 1839) (Story, J.) ("I never have entertained any doubt of the constitutional authority of congress" to enact a 14-year patent extension that "operates retrospectively"); see also Evans v. Robinson, 8 F. Cas. 886, 888 (No. 4,571) (CC Md. 1813) (Congresses "have the exclusive right . . . to limit the times for which a patent right shall be granted, and are not restrained from renewing a patent or prolonging" it.).7
Further, although prior to the instant case this Court did not have occasion to decide whether extending the duration of existing copyrights complies with the "limited Times" prescription, the Court has found no constitutional barrier to the legislative expansion of existing patents.8 McClurg v.
7 Justice Stevens would sweep away these decisions, asserting that Graham v. John Deere Co. of Kansas City, 383 U. S. 1 (1966), "flatly contradicts" them. Post, at 237. Nothing but wishful thinking underpins that assertion. The controversy in Graham involved no patent extension. Graham addressed an invention's very eligibility for patent protection, and spent no words on Congress' power to enlarge a patent's duration.
8 Justice Stevens recites words from Sears, Roebuck & Co. v. Stiffel Co., 376 U. S. 225 (1964), supporting the uncontroversial proposition that a State may not "extend the life of a patent beyond its expiration date," id., at 231, then boldly asserts that for the same reasons Congress may not do so either. See post, at 222, 226. But Sears placed no reins on Congress' authority to extend a patent's life. The full sentence in Sears, from which Justice Stevens extracts words, reads: "Obviously a State could not,
