Trade Dress Infringement: Protecting Product Design and Packaging

Last updated: November 2026

Trade dress is the total image of a product or its packaging: shape, color, design, texture, graphics, even a restaurant's decor. Trade dress infringement is actionable under section 43(a) of the Lanham Act when the dress is distinctive, is not functional, and the defendant's imitation is likely to confuse consumers about source. (15 U.S.C. § 1125(a)(1)(A), (a)(3).) For product design, distinctiveness must be proved through secondary meaning. Kolmogorov Law, P.C. litigates trade dress claims for Orange County, Los Angeles, and other California businesses.

What trade dress covers

A trademark is usually a word or a logo. Trade dress is everything else that tells a customer where a product came from: the shape of a bottle, the color scheme of a box, the layout of a store, the configuration of the product itself. The Lanham Act does not use the term in its definition of a mark, but section 43(a) reaches any word, term, name, symbol, or device, or any combination of them, used in a way likely to cause confusion. (15 U.S.C. § 1125(a)(1)(A).) Courts have read that language to cover a product's overall appearance for decades.

Trade dress can be registered as a mark, and some of it is. Most trade dress cases, though, involve unregistered dress, and the statute puts an extra burden on that plaintiff.

The three elements of trade dress infringement

To win a trade dress claim, the plaintiff proves three things. The dress is distinctive, either inherently or because it has acquired secondary meaning. The dress is not functional. And the defendant's dress is likely to cause confusion about the source or sponsorship of the goods. For unregistered trade dress, the plaintiff bears the burden of proving non-functionality. (15 U.S.C. § 1125(a)(3).) Each element is a separate fight, and the first two are where most claims are lost.

Packaging versus product design

The Supreme Court drew a line that controls these cases. Product packaging can be inherently distinctive, because customers expect packaging to signal source. Product design cannot. A plaintiff claiming the design of the product itself must prove secondary meaning: that the buying public associates the design with a single source. (Wal-Mart Stores, Inc. v. Samara Brothers, Inc. (2000) 529 U.S. 205, 216.) When it is unclear whether a feature is packaging or design, courts classify it as design and require secondary meaning. (Id. at p. 215.)

That rule has consequences for a small business. A distinctive box or label can be protected from the first sale. The shape of the product inside it is protected only after enough advertising and sales that customers recognize it. That usually takes years, and it takes proof: sales figures, advertising that features the design, unsolicited press, copying by competitors, and sometimes a survey.

Functionality

A feature that is essential to the use or purpose of the product, or that affects its cost or quality, is functional and cannot be trade dress, no matter how recognizable it is. The reason is patent policy. Useful designs are protected, if at all, by utility patents for a limited time; trademark law cannot extend that protection forever. Courts also treat as functional a design feature that competitors need in order to compete effectively, sometimes called aesthetic functionality. A plaintiff whose own advertising touts the design's advantages has written the defendant's brief for it.

Likelihood of confusion

Once distinctiveness and non-functionality are established, the confusion analysis is the same one used for word marks, under the Sleekcraft factors. Our page on proving infringement walks through them. In trade dress cases the comparison is of the overall impression of the two products as they sit on a shelf or a screen, not a feature-by-feature checklist. A defendant who copied the look but added its own name in small type has not necessarily avoided confusion.

How it comes up for business owners

A consumer products company finds a competitor's product on a marketplace in a box that mirrors its own: same colors, same layout, same photography style, different name. That is a packaging case, and a strong one if the packaging is distinctive. Our marketplace complaints page covers the fast first step.

A restaurant group learns that a former manager has opened a competing location with the same interior design, menu format, and uniforms. That is a decor case, treated like packaging, and the question is whether the overall look is distinctive or just the common style of the category.

A maker of a well-known tool shape sees a knockoff with the same silhouette. That is a product design case. The maker must prove secondary meaning and must confront the functionality argument, and a design patent or copyright, if the maker had obtained one, may be the better claim. We handle the litigation of those rights; our copyright registration guide explains that filing.

Remedies and where cases are heard

A successful trade dress plaintiff can obtain an injunction, the defendant's profits, its own damages, and in exceptional cases attorney fees. (15 U.S.C. §§ 1116(a), 1117(a).) Our damages and remedies page covers them. The claim is heard in federal court, for Orange County at the Ronald Reagan Federal Building in Santa Ana and for Los Angeles at the First Street Courthouse, often with a California unfair competition claim alongside it. (Bus. & Prof. Code, § 17200.)

What to bring to the first meeting

Samples or clear photographs of your product and packaging and the competitor's, side by side. The date you adopted the design and every version since. Advertising that features the look itself, not just the name. Sales figures by year. Any press or customer comments about the design. And any patent, copyright, or trademark filings covering it.

Frequently asked questions

What is trade dress?

The overall look of a product or its packaging that identifies its source: shape, color, graphics, layout, and the combination of them. It is protected under section 43(a) of the Lanham Act when it is distinctive and not functional. (15 U.S.C. § 1125(a)(1)(A), (a)(3).) Store and restaurant decor can qualify.

How do you prove trade dress infringement?

Show that your trade dress is distinctive, that it is not functional, and that the defendant's imitation is likely to confuse consumers about source. For unregistered dress you carry the burden on functionality. (15 U.S.C. § 1125(a)(3).) For product design you must prove secondary meaning. (Wal-Mart Stores, Inc. v. Samara Brothers, Inc. (2000) 529 U.S. 205, 216.)

Can product packaging be a trademark?

Yes. Distinctive packaging can be protected as trade dress from first use, and it can be registered as a mark. The packaging must do more than look attractive; it must serve to identify the source. Ordinary or common packaging for the category gets no protection.

Can I protect the shape of my product?

Only with proof of secondary meaning, and only if the shape is not functional. The Supreme Court has held that product design is protected as trade dress only on that showing. A design patent, where available, protects a new ornamental design without that proof for a limited term, and copyright may cover separable artistic features. We litigate those rights but do not prosecute patents.

Is trade dress infringement the same as counterfeiting?

No. Counterfeiting requires a spurious mark identical to or substantially indistinguishable from a registered mark. (15 U.S.C. § 1127.) Most trade dress cases involve a look-alike, not an identical copy, and unregistered dress is not eligible for the counterfeiting remedies at all.
