Mazer v. Stein: Art Keeps Its Copyright Even as a Lamp Base

Mazer v. Stein, 347 U.S. 201 (1954), decided whether a work of art forfeits copyright protection when it is mass-produced and put to a practical, commercial use. The respondents, Stein and his company, created original statuettes of male and female dancing figures in semivitreous china, registered them as works of art with the Copyright Office, and then sold them both as standalone sculptures and, far more often, as bases for fully wired electric table lamps. When a competitor, Mazer, copied the statuettes and sold its own lamps, Stein sued for infringement. Mazer argued that once a sculpture is manufactured in quantity and embodied in a utilitarian article — a lamp — it belongs to the domain of design patents, not copyright, and loses any copyright it might once have had. Writing for the Court, Justice Reed rejected that argument and held that neither mass production nor intended use in a useful article defeats copyright in the artistic work.

The facts and the copyright-versus-design-patent objection

Stein’s statuettes were unmistakably sculptural: small, original figures of dancers, conceived and executed as works of art. Stein obtained copyright registrations for them as “works of art” under the Copyright Act, then licensed them into commerce chiefly as lamp bases, wiring each figure with a socket, harp, and shade to make a finished lamp. The commercial success of the lamps, not any market for the bare statuettes, drove the enterprise — and drove the copying. Mazer produced knock-off statuettes and marketed competing lamps.

Mazer’s defense was categorical rather than factual. It did not deny that the figures were artistic or that it had copied them. It argued that the works had crossed a doctrinal boundary: art that is industrialized — reproduced in quantity and made the functional element of a manufactured product — is the proper subject of a design patent, which protects ornamental designs of articles of manufacture subject to patent law’s rigorous standards and shorter term. To let a creator claim a long, easily obtained copyright over what was really an industrial design, Mazer contended, would let copyright swallow the design-patent regime and monopolize useful articles.

The Court’s holding: dual protection and no forfeiture

Justice Reed’s opinion made several moves that continue to structure the law. First, the Court held that the availability of design-patent protection does not preclude copyright. The two systems are not mutually exclusive; a work eligible for a design patent may also, insofar as it is an original work of art, be protected by copyright, and the existence of one regime does not oust the other. An author need not choose patent over copyright merely because the artistic object could conceivably qualify for both.

Second, and central to the holding, the Court ruled that neither the intended use of the statuettes as lamp bases nor their manufacture and sale in large numbers stripped them of copyright. “We find nothing in the copyright statute to support the argument that the intended use or use in industry of an article eligible for copyright bars or invalidates its registration,” Reed wrote. The figures were works of art when created; embedding them in a lamp and reproducing them commercially did not transform them into something copyright refused to protect. The Court also relied heavily on the long-standing administrative practice of the Copyright Office, which had for decades registered artistic works of exactly this kind, and on the corresponding regulatory recognition that works of art could be embodied in useful articles — an interpretive gloss Congress had left undisturbed through successive reenactments.

Third, the Court took care to define the scope of what copyright secured. Copyright protects only the expression — the artistic form of the statuette — not the idea, and it confers no monopoly over the lamp’s utilitarian function. “Unlike a patent,” Reed explained, “a copyright gives no exclusive right to the art disclosed; protection is given only to the expression of the idea — not the idea itself.” Stein could stop others from copying his particular sculpted dancers, but he could not use copyright to bar anyone from making lamps, or from independently designing different figures to serve the same practical purpose. That limitation reconciled the holding with the constitutional and statutory design: copyright rewards original expression without granting control over the useful article itself.

From Mazer to the separability doctrine

Mazer answered the forfeiture question but did not fully articulate how to separate protectable art from unprotectable function when the two are fused in a single object. Following the decision, the Copyright Office amended its regulations to recognize that the “artistic features” of a useful article are copyrightable only insofar as they can be identified separately from the article’s utilitarian aspects, and Congress codified that principle in the 1976 Act. The Act’s definition of “pictorial, graphic, and sculptural works” protects the design of a useful article “only if, and only to the extent that, such design incorporates pictorial, graphic, or sculptural features that can be identified separately from, and are capable of existing independently of, the utilitarian aspects of the article.” That is the separability test, and Mazer is its origin: the statuette was easily separable because it was a complete sculpture that happened to be used as a base.

The Court returned to this terrain in Star Athletica, L.L.C. v. Varsity Brands, Inc. (2017), which addressed the two-dimensional decorative designs on cheerleading uniforms. Building on Mazer, the Court held that a feature of a useful article is eligible for copyright if it can be perceived as a two- or three-dimensional work of art separate from the article and would qualify as a protectable work — on its own or fixed in some other medium — if imagined apart from the useful article. Mazer’s core insight, that art embedded in a functional product keeps its copyright, thus runs straight through to modern doctrine.

Open questions

Because Mazer involved a freestanding sculpture that merely doubled as a lamp base, it did not have to resolve the hard cases where artistic and functional elements are genuinely inseparable — industrial designs, fashion garments, furniture, and product shapes whose aesthetic and utilitarian features cannot be teased apart. Courts spent decades developing competing separability tests (physical versus conceptual separability, and several variants) before Star Athletica attempted a unifying rule. Even after Star Athletica, disputes persist over how to apply the “imagine it separately” inquiry to three-dimensional designs and over the line between protectable surface decoration and unprotectable useful shape. Mazer supplied the foundational principle; the boundary work it left open remains contested.

Implications

• Functional use does not forfeit copyright. Embedding an original artistic work in a useful, mass-produced article does not destroy the copyright in the work’s artistic features.
• Copyright and design patents can coexist. A design eligible for a design patent may also be protected by copyright; the creator is not forced to elect one regime.
• Copyright protects expression, not function. Copyright in the artistic work confers no exclusive right over the utilitarian article or its function — only over copying the protected expression itself.
• Separability is the modern gatekeeper. Mazer’s principle survives as the useful-articles/separability doctrine, codified in the 1976 Act and refined in Star Athletica; artistic features are protected only to the extent they can be identified and imagined separately from the article’s utility.

Frequently asked questions

What did Mazer v. Stein hold? The Supreme Court held that statuettes of dancing figures were copyrightable as works of art, and that they did not lose copyright protection because they were mass-produced and used as the bases of electric lamps. A work of art incorporated into a useful article retains its copyright in its artistic features.

Does using art in a functional product forfeit its copyright? No. Mazer established that intended or actual use as an element of a manufactured, utilitarian article does not bar or forfeit copyright in the artistic work itself. The copyright protects the expression embodied in the sculpture; it does not give any exclusive right over the lamp’s mechanical or utilitarian function.

How does Mazer relate to the modern useful-articles test? Mazer is the doctrinal ancestor of today’s separability analysis. Congress codified its principle in the 1976 Act’s definition of “pictorial, graphic, and sculptural works,” which protects design features of a useful article only if they can be identified separately from, and exist independently of, the article’s utilitarian aspects — the test the Supreme Court later refined in Star Athletica v. Varsity Brands (2017).
