Mazer v. Stein
The Supreme Court ruled that statuettes copyrighted as "works of art" don't lose their copyright protection just because they were designed to double as table lamp bases and sold that way in bulk.
The decision means an artist's copyright can coexist with commercial, mass-produced use of the same design, so long as competitors are only barred from copying the artistic form itself, not from making similar useful lamps.
“Unlike a patent, a copyright gives no exclusive right to the art disclosed; protection is given only to the expression of the idea”
Explaining the core difference between patent and copyright protection.
How it got here: A federal trial court dismissed the infringement suit; the Fourth Circuit reversed and upheld the copyrights; the losing lamp manufacturers asked the Supreme Court to review the ruling.
The Case in Depth
What happened
A sculptor made original clay statuettes of male and female dancing figures, which were cast in china and sold mostly as bases for electric table lamps, with wiring and shades attached. The sculptor's business partners registered the statuettes for copyright as \"works of art.\" A rival lamp-making partnership copied the statuettes and used them in their own lamps without permission, prompting an infringement lawsuit.
The question before the Court
Could a sculptor keep a copyright on statuettes that were designed and sold mainly as lamp bases?
Why it matters
The ruling let manufacturers protect ornamental designs used on everyday products through copyright rather than the more demanding design-patent process, shaping how companies protect the look of lamps, housewares, and other mass-produced goods that combine art with utility.
What changes now
The ruling is final on the merits and affirms that the statuettes' copyrights are valid, meaning the copying lamp manufacturer remains liable for infringement. Justice Douglas's concurrence flagged an unresolved constitutional question -- whether sculptural works count as 'writings' under the Constitution's Copyright Clause -- and urged the case be reargued on that point, but the majority did not take up that suggestion, leaving the constitutional question open for a future case.
What this does not decide
The Court expressly limited itself to the copyright question and did not decide whether the statuettes could also have been protected by a design patent, nor whether obtaining one form of protection would have barred the other. It also left unresolved a constitutional question, raised only by the concurrence, about whether sculptures qualify as 'writings' under the Constitution.
Concurrences and dissents
Concurrence — Justice Douglas
Justice Douglas agreed with the Court's statutory analysis but flagged a deeper constitutional question the majority didn't address: whether a sculptor counts as an 'author' and a statue as a 'writing' under the Constitution's Copyright Clause. He noted this had never been squarely decided and that the constitutional materials on the question were thin. Rather than deciding it now, he argued the case should be put down for reargument so the issue could be fully briefed.
How the Court got there
The legal reasoning, step by step
- The Court traced the history of the copyright statute, showing Congress steadily expanded protectable subject matter from books and maps to paintings, statues, and eventually removed language limiting protection to the 'fine arts,' signaling an intent to cover art with practical uses too.
- It looked to the Copyright Office's own long-standing practice of registering decorative items with utilitarian functions -- lamps, bookends, ashtrays -- as evidence that the agency charged with administering the law had consistently read 'works of art' broadly.
- The Court held that whether a work qualifies for copyright turns only on whether it is an original, tangible expression of the artist's ideas -- not on whether the artist intends it to be mass-produced or incorporated into a manufactured product.
- Applying that standard, the Court found the dancing-figure statuettes were original sculptural works regardless of their later use as lamp bases, so their intended and actual use as lamp components did not disqualify them from copyright.
- The Court distinguished copyright from design-patent protection: copyright protects only the artistic expression itself, not the useful article's mechanical or functional features, so a copyright holder cannot stop others from making similar lamps -- only from copying the statuette's artistic form.
- Because patentability and copyrightability serve different purposes and nothing in either statute makes one exclude the other, the Court held that a work being potentially eligible for a design patent does not bar it from also qualifying for copyright.
