What Is Trade Dress for Product Designs? What the Statute and the Supreme Court Say

Direct answer: Cornell's Legal Information Institute defines trade dress as "the design and shape of the materials in which a product is packaged," and says "Product configuration, the design and shape of the product itself, may also be considered a form of trade dress." Whether a particular design is protected depends on the facts and on the court. This guide only reports what the statute and one Supreme Court opinion say. It is not legal advice.

TL;DR: For unregistered trade dress, the federal statute puts the burden on the person claiming protection to prove the design "is not functional." In a 2000 case about product design, the Supreme Court held that a product's design is protectible "only upon a showing of secondary meaning." If someone raises trade dress about your product, read the exact claim and consider talking to a lawyer.

What trade dress is

Cornell's Wex entry says: "The Lanham Act protects trade dress if it serves the same source-identifying function as a trademark." It adds that "It is possible to register a trade dress as a trademark, but for practical reasons most trade dress and product configurations are protected without registration under 15 U.S.C. § 1125(a)." That entry was last reviewed in June 2024 per its page.

Note the framing. In these sources trade dress is about identifying who made a product, the same job a trademark does. For the copyright side of designs, see who owns the copyright in designs in a bundle.

What the statute says about the burden

15 U.S.C. § 1125(a)(3) reads: "In a civil action for trade dress infringement under this chapter for trade dress not registered on the principal register, the person who asserts trade dress protection has the burden of proving that the matter sought to be protected is not functional."

So for unregistered trade dress, the statute assigns the burden to the party asserting it. The statute does not say how a court decides what counts as functional in a given case.

What the Supreme Court held about product design

In Wal-Mart Stores, Inc. v. Samara Brothers, Inc. (2000), the Court wrote: "We hold that, in an action for infringement of unregistered trade dress under 43(a) of the Lanham Act, a product's design is distinctive, and therefore protectible, only upon a showing of secondary meaning."

The Court explained "secondary meaning" this way: it "has since come to refer to the acquired, source-identifying meaning of a non-word mark". That is a holding about product design as such. The opinion also treats packaging separately and notes there "will indeed be some hard cases at the margin". Do not read it as a rule about every design or every claim.

What this means for sellers

Where a preflight helps

A BundleShield preflight is a check you run before you list. It takes your ZIP with the license text inside and flags brand-name patterns in filenames and readable license text, byte-identical duplicates and unsafe active content, with a per-file result of Clear, Review or Remove and the reason attached. It does not scan the artwork, so it cannot tell whether a design resembles someone's trade dress. Clear means no issue flagged by these limited checks. The checks are rule-based: every upload is checked against the same rubric, the same way. A risk check, not legal clearance. See what a report looks like on the sample report page.
