If a competitor copies the look and feel of your packaging, retail space, restaurant interior, or branded display, the legal issue may involve trade dress. In general terms, trade dress is a branch of trademark law that can protect the overall visual appearance of goods or services when that appearance helps consumers identify source. That protection can extend beyond names and logos to packaging, décor, layouts, color arrangements, and other design elements in the right circumstances.
This area gets technical quickly. A box shape that feels distinctive to a founder may look ordinary to a court. A striking store interior may still be unprotectable if its design features are functional. And even strong visual branding often turns on evidence: consumer recognition, consistency of use, and proof that the claimed look is more than decoration.
In this post, you’ll learn how courts and the USPTO generally evaluate whether product packaging or store design may qualify for trade dress protection, what makes these claims stronger or weaker, and when an attorney may help assess whether the design is protectable or just visually appealing. If you want a broader foundation first, this overview of how trade dress law treats visual branding and consumer confusion provides helpful context.

Under the Lanham Act, unregistered trade dress can be enforced if its use is likely to cause confusion and the claimed dress is not functional. Federal law also places the burden of proving nonfunctionality on the party asserting unregistered trade dress rights. See 15 U.S.C. § 1125(a).
Courts and the USPTO describe trade dress broadly enough to include product design, product packaging, color, and even the interior of a restaurant or similar service environment. The USPTO’s Trademark Manual of Examining Procedure explains that trade dress may include the packaging in which a product is sold and recognizes that the interior of a restaurant has been treated as akin to product packaging in the service context. See TMEP § 1202.
That distinction matters because the legal test is not always the same for:
A lot of real-world disputes sit near the line between these categories. And when the classification is unclear, the law often treats the design more skeptically.
One of the biggest legal dividing lines comes from the Supreme Court’s decision in Wal-Mart Stores, Inc. v. Samara Bros.. The Court held that product design trade dress can never be inherently distinctive and therefore requires proof of secondary meaning, meaning consumers have come to associate the design with a single source. The USPTO follows the same rule and notes that ambiguous trade dress is treated as product design. See TMEP § 1202.02.
That makes classification step one.
In Two Pesos, Inc. v. Taco Cabana, Inc., the Supreme Court held that inherently distinctive trade dress can be protected under Section 43(a) without proof of secondary meaning. That case involved the overall décor of a restaurant, and the USPTO still cites it as an example of service-environment trade dress similar to packaging. See Two Pesos and TMEP § 1202.
So if the claimed look is truly packaging or store décor, there may be a path to arguing inherent distinctiveness. If the claimed look is really the product itself, the claimant generally ends up in the tougher secondary-meaning lane.
