Whether Universal infringed the plaintiff’s copyright by using the general plot, characters, and incidents of “Abie’s Irish Rose” in “The Cohens and The Kellys.”
Holding
No. The similarities were too abstract and generalized to constitute protected expression, and the two works differed substantially in their plots and characters.
Reasoning
Copyright protection cannot be confined to exact words; otherwise, a copier could evade liability through trivial changes. But the law also does not grant an author ownership over ideas. When a claimed appropriation concerns the overall structure of a play rather than a scene or dialogue copied verbatim, the court must distinguish protected expression from the underlying ideas expressed by the work.
Judge Hand described a spectrum of abstraction. A play may be described at increasingly general levels: first through particular scenes and incidents, then through broader plot patterns, and finally through a bare statement of its theme. At some point, the shared description becomes too general to protect. No fixed formula identifies that point, but courts must draw the line case by case.
Plots and characters may in principle receive protection when copied with sufficient specificity. A later work could infringe by closely reproducing a sufficiently developed character, just as it could infringe by taking a sufficiently concrete plot. But broad character types and generalized dramatic situations remain free for later authors to use. The less developed a character is, the narrower any copyright protection will be.
The plaintiff’s play concerns two religiously zealous fathers who oppose an interfaith marriage and eventually yield because of affection for their grandchildren. Universal’s film does not share that central dramatic conception. Religion plays no material role in the film; its reconciliation follows the Jewish father’s honest surrender of an inheritance and the Irish father’s generosity, not grandparental affection.
The common elements—a Jewish and an Irish father who quarrel, the marriage of their children, the birth of a grandchild, and eventual reconciliation—were only a generalized background or theme. Even if the plaintiff first made that subject popular, she could not monopolize it. A copyright protects her particular treatment, not the broad premise of conflict between Irish and Jewish families connected by their children’s marriage.
The characters likewise lacked actionable similarity. The young lovers in both works were only minimally developed: they were in love and had a child. The plaintiff’s Jewish father was a warm, patriarchal religious zealot, while the defendant’s was a vulgar, ostentatious man whose eventual honesty drives the resolution. The Irish fathers also served materially different functions. Any overlap consisted largely of familiar comic types and general traits, not protected character expression.
