"Toward a Fair Use Standard", 103 Harv. L. Rev. 1105 (1990) (alt. citation: v.103, n5. March 1, 1990), is an influential 1990 law review article on the fair use doctrine in US copyright law, written by then-District Court Judge Pierre N. Leval. The article argued that the most critical element of the fair use analysis is the transformativeness of a work, the first factor in the statutory factors listed in 17 U.S.C. 107.
Leval's article is widely accepted as initiating a shift in judicial treatment of copyright fair use cases, toward a transformativeness analysis and away from emphasizing the "commerciality" analysis of the fourth factor. Prior to Leval's article, the fourth factor had often been described as the most important of the factors.
In his article, Leval noted:
I believe the answer to the question of justification turns primarily on whether, and to what extent, the challenged use is transformative. The use must be productive and must employ the quoted matter in a different manner or for a different purpose from the original. ...[If] the secondary use adds value to the original—if the quoted matter is used as raw material, transformed in the creation of new information, new aesthetics, new insights and understandings—this is the very type of activity that the fair use doctrine intends to protect for the enrichment of society.
Leval's thesis was generally critiqued by Lloyd Weinreb in 1990, in "Fair's Fair: A Comment on the Fair Use Doctrine", 103 Harvard Law Review 1137 (1990).
