Copyright protects an author’s original expression, not the underlying facts, ideas, themes, or stock elements used to tell a story. Although substantial similarity ordinarily presents a factual question, summary judgment is appropriate where the claimed common material falls entirely outside copyright protection.
reasoning
Many of Alexander’s comparisons involved historical or contemporary facts, such as slavery, manumission, abolitionism, westward settlement, and the presence of mixed-race women in New Orleans. Haley could use such facts even if he had learned of them from Jubilee, because facts do not become proprietary when an author includes them in a work.
reasoning
Other alleged overlaps came from common sources, public-domain material, and Black American folk customs. Practices such as laying out a body on a cooling board, using herbal remedies, cockfighting, and jumping the broom reflected shared cultural history rather than Alexander’s original expression.
reasoning
The court also treated many asserted parallels as scenes a faire: standard or practically inevitable incidents in a narrative about American slavery. Escapes through woods, pursuit by dogs, the separation and sale of enslaved family members, sexual exploitation by slaveholders, punishment, and songs of sorrow or joy are conventional elements of the subject matter, not protectable literary choices belonging to one author.
reasoning
Still other comparisons rested on clichés, ordinary words, stock phrases, or conventional descriptions, including terms such as “poor white trash” and familiar descriptions of cotton. Copyright does not grant an author ownership of language, stereotypes, or the limited ways in which an idea may commonly be expressed.
reasoning
Several proposed similarities showed only a shared theme or setting, such as puberty, youthful sexuality, or religious hypocrisy. Those elements are the unprotected skeleton of a story; copyright protects the author’s particular expression, not general subject matter.
reasoning
Finally, some comparisons failed at the factual level because the passages did not actually depict the same event. For example, Alexander characterized a passage in Roots as a secret organized religious meeting, but the court found that it was neither secret nor religious nor an organized meeting. Taken together, the comparisons were strained, scattered, and legally insufficient.
