Legal doctrines are not static commandments; they evolve through judicial iteration and technological pressure. Explore the lineages of Transformative Use, Idea/Expression Dichotomy, Alice/Mayo Patent Eligibility, and the Functionality Doctrine.
Origin: Folsom v. Marsh (1841) / Leval Commentary (1990)
The dominant inquiry under Factor 1 of Fair Use (§ 107), assessing whether a secondary work alters the original with new expression, meaning, or message, or serves a distinct commercial/functional purpose.
Coined the term 'transformative use' in 'Toward a Fair Use Standard'.
Adopted Leval's formulation into SCOTUS jurisprudence for parody.
Expanded transformativeness to computational search indexes without altering text.
Applied transformativeness to software declaring code for cross-platform utility.
Recalibrated test: secondary use sharing the same commercial objective is not transformative without independent justification.
Does the secondary use serve a genuinely distinct purpose from the original's primary market?
Post-Warhol requires looking at the specific transaction/license, not merely broad artistic nuance.
Does the new work create commentary, criticism, or indexing rather than a derivative adaptation?
Protects § 106(2) exclusive right to prepare derivative works from being swallowed.
If commercial, is copying the original work reasonably necessary to achieve the transformative purpose?
Parody requires taking the original; satire does not.
