Rapaport v. Nivoda

Judge: William Nardini
Opinion Date: September 4, 2026

A company that provides information to the diamond industry publishes a weekly price list for diamonds, categorizing them by attributes such as size, color, and clarity. This list, which the company claims is based on its expert opinion and proprietary methods, is distributed to paid subscribers. The company alleged that another business operating an online diamond marketplace copied prices from this list and displayed them on its website, showing the difference between its own prices and those in the list.

The United States District Court for the Southern District of New York granted the defendant’s motion to dismiss the complaint. The district court found that the “merger doctrine” applied, reasoning that the idea of the market price for diamonds based on their characteristics could only be expressed in one way—by the specific numbers listed—and that protecting these numbers would impermissibly grant copyright protection to an idea rather than its expression. The district court did not reach other arguments, such as whether the plaintiff had proper copyright registration or whether fair use applied.

On appeal, the United States Court of Appeals for the Second Circuit reviewed the district court’s decision de novo. The appellate court held that the district court erred in applying the merger doctrine at the motion to dismiss stage, as there were unresolved factual questions about how the price list was created and whether the prices could only be expressed in one way. The appellate court concluded that, based on the complaint’s allegations, the list may reflect the plaintiff’s opinion and expert judgment, not just objective market facts. The Second Circuit vacated the district court’s judgment and remanded the case for further proceedings, including consideration of alternative grounds for dismissal. View “Rapaport v.
