Whether copyright protection in a factual compilation extends to the underlying facts collected by the compiler.
Holding
No. Facts are never copyrightable, and a compilation copyright protects only original expression in the compiler's selection, coordination, or arrangement of those facts.
Reasoning
The constitutional and statutory foundation of copyright is originality. A work must be independently created and possess at least a minimal degree of creativity. Facts fail this test because they are discovered rather than created: the person who first finds or reports a fact is not its author or originator.
A factual compilation may qualify for copyright because a compiler can make original choices about which facts to include and how to select, coordinate, or arrange them. But the resulting copyright is necessarily thin. It protects those original choices, not the underlying facts, which remain in the public domain for later authors to use.
The Court rejected the older "sweat of the brow" or "industrious collection" doctrine, under which copyright rewarded the labor spent gathering facts and effectively barred competitors from using the gathered information. That approach improperly creates a monopoly over public-domain facts and conflicts with the constitutional purpose of copyright, which protects original expression while allowing others to build on facts and ideas.
The 1976 Copyright Act confirms this rule. Section 102(a) requires an original work of authorship; § 102(b) denies copyright protection to ideas, discoveries, and facts; § 101 defines a copyrightable compilation as one whose selection, coordination, or arrangement makes the work original; and § 103(b) limits a compilation copyright to the compiler's original contributions rather than the preexisting material.
