Anne Nichols authored the enormously successful 1922 stage play 'Abie's Irish Rose,' a comedy about the interfaith marriage of a Jewish man and an Irish Catholic woman and the ensuing conflict between their bigoted, strong-willed fathers. The play's comedic set pieces include ethnic stereotypes, misunderstandings, religious officiants (a rabbi and a priest), and ultimately a reconciliation catalyzed by the birth of grandchildren. Universal Pictures released the 1926 motion picture 'The Cohens and the Kellys,' the first in a series about a feuding Irish family (the Kellys) and a Jewish family (the Cohens) who are neighboring shopkeepers. The film also featured bickering patriarchs of Irish and Jewish descent, comic set pieces arising from cultural and religious differences, and a romance between the younger generation that softens the feud and leads toward reconciliation. Nichols sued Universal in federal court, alleging that the film unlawfully copied protected elements of her play's plot, characters, and scenes. The district court entered judgment for Universal, concluding that any similarities were at the level of ideas and stock materials. Nichols appealed to the Second Circuit.
Did Universal's film unlawfully infringe Nichols's copyright by appropriating protectable expression from 'Abie's Irish Rose,' or did it merely use unprotectable ideas, stock characters, and generalized plot elements common to works about interfaith romance and feuding families?
Copyright protects an author's particular expression of an idea, not the idea itself. Similarity that exists only at higher levels of abstraction—such as themes, basic plots, stock characters, or incidents that naturally flow from a premise—is not infringement. Judge Learned Hand's 'abstractions' test recognizes a continuum from concrete details (protectable) to increasingly general ideas (unprotectable), and infringement turns on whether the defendant appropriated the plaintiff's protected expression (e.g., distinctive character delineation and sequence of incidents) rather than unprotected generalities. The less developed and more stereotyped a character, the less copyright protection it receives.
No infringement. The similarities between the works existed only at the level of unprotectable ideas—ethnic families (Irish and Jewish), interfaith romance, parental opposition, and ultimate reconciliation—and the defendant did not appropriate the plaintiff's protected expression or sufficiently delineated characters. The Second Circuit affirmed judgment for Universal.
Judge Learned Hand emphasized that once literal copying is not at issue, courts must distinguish between an author's protected expression and unprotected general ideas. He explained that any narrative can be described at increasing levels of abstraction. As one moves upward—from specific dialogue, incidents, and detailed character traits, to more general plot outlines and finally to broad themes—copyright protection diminishes and ultimately disappears. No author can monopolize general ideas, such as a romantic comedy about feuding ethnic families reconciled by the marriage of their children. Applying that framework, the court found that the overlap between the play and the film—Irish and Jewish patriarchs, interfaith romance, comedic culture clash, rabbi/priest set pieces, and reconciliation via the younger generation—was confined to the generalized premise and stock comedic devices long present in dramatic literature. The detailed sequence of incidents, the arrangement of scenes, and the specific development of characters in the film differed materially from the play. On character protection, the court stressed that stereotyped or lightly sketched figures—such as a gruff Irish father or parsimonious Jewish father—are not protectable as such; 'the less developed the characters, the less they can be copyrighted.' While distinctive, well-delineated characters might be protectable, the figures here were conventional types lacking the unique, concrete traits that would warrant exclusive rights. Judge Hand also observed that many similarities were scènes à faire—elements that naturally flow from the chosen premise of an interfaith, interethnic romantic comedy (e.g., religious officiants, parental quarrels, culture-specific jokes). Because such elements are effectively dictated by the idea and are common in the genre, they are not protected expression. Even assuming defendants had access and drew inspiration from the play, they did not take the plaintiff's protected arrangement of incidents or distinctive character expression; they adopted only unprotectable ideas and conventions.
Nichols is a foundational case defining the idea–expression dichotomy and introducing the 'abstractions' test that remains central to substantial similarity analysis. It teaches that infringement requires appropriation of protectable expression—distinctive character delineation, concrete sequences of incidents, and original arrangements—not mere borrowing of themes, genres, stock characters, or predictable set pieces. The case also anchors modern approaches to character copyrightability and anticipates the scènes à faire doctrine. Law students repeatedly encounter Nichols across IP courses and in later cases applying or refining its principles in film, television, and literary disputes.
Nichols v. Universal Pictures crystallizes the modern approach to copyright infringement of narrative works: protection for expression, freedom for ideas. By mapping similarity onto an abstraction continuum, Judge Learned Hand provides a durable, flexible tool that helps courts and practitioners sort protectable detail from unprotectable theme.
