Reference excerpt

Mazer v. Stein, 347 U.S. 201 (1954), was a copyright case decided by the United States Supreme Court. In an opinion written by Justice Stanley F. Reed, the Supreme Court held that the statuettes—male and female dancing figures made of semivitreous china—used as bases for fully equipped electric lamps were copyrightable, even though the lamp itself was a utilitarian mass-produced item. The case is notable for the quotation, "Unlike a patent, a copyright gives no exclusive right to the art disclosed; protection is given only to the expression of the idea—not the idea itself." 347 U.S. at 217 (citing F. W. Woolworth Co. v. Contemporary Arts, 193 F.2d 162; Ansehl v. Puritan Pharmaceutical Co., 61 F.2d 131; Fulmer v. United States, 122 Ct. Cl. 195, 103 F.Supp. 1021; Muller v. Triborough Bridge Authority, 43 F.Supp. 298.) Congress incorporated the Mazer decision into the Copyright Act of 1976 as the concept of separability. For many years, there was confusion over how to determine separability, so tests proliferated and competed against one another. The Supreme Court addressed this issue in the 2017 case Star Athletica, LLC v. Varsity Brands, Inc. and created a canonical test for separability.

Worked examples

Example 1 — a first encounter with Mazer v. Stein

Start with the simplest possible case. Write down what Mazer v. Stein claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mazer v. Stein before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mazer v. Stein ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mazer v. Stein

In research: Mazer v. Stein appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mazer v. Stein in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mazer v. Stein is common in secondary-school and first-year university syllabi. It links to neighbouring topics Light fixtures, United States Supreme Court cases, United States Supreme Court cases in 1954, so understanding it makes those chapters shorter.
In everyday life: Look for Mazer v. Stein outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
