What to Do in Trade Dress Infringement Cases

Picture this: you walk down the cereal aisle and grab a box without reading the label, because you know the colors and shape at a glance. That instant recognition is exactly what trade dress law protects. When a rival brand mimics your packaging, your store layout, or the overall look of your product closely enough to confuse shoppers, you may have a trade dress infringement case on your hands. Here's what that actually means and what to do about it.

What Counts as Trade Dress

Trade dress covers the total visual image of a product or business — not just a logo or name, but the whole package. Courts have found trade dress protection in things like:

• The shape and color combination of a product (think the distinctive contour of a Coca-Cola bottle)

• Packaging design, including color schemes, layout, and graphics

• Restaurant décor and layout — this is actually how the concept got a big legal boost, in a Supreme Court case involving Taco Cabana's Mexican-themed restaurant design

• Product configuration, meaning the design of the product itself

Two things separate protectable trade dress from an ordinary design choice. First, it has to be distinctive — either inherently, or because it's earned "secondary meaning," meaning customers associate that look with your brand specifically. Second, it can't be functional. If a feature exists because it makes the product work better or cheaper to manufacture, trademark law generally won't protect it; that's what patent law is for.

How Infringement Gets Proven

To win a trade dress case under the Lanham Act (the federal law that governs this), you generally need to show three things:

1. Your trade dress is distinctive or has acquired secondary meaning

2. It's non-functional

3. The defendant's trade dress is confusingly similar, to the point where an average consumer might think the two products come from the same source or are affiliated

That third point is where most of the real fighting happens. Courts look at factors like how similar the designs actually are, whether there's evidence of actual customer confusion, how sophisticated the buyers are, and whether the alleged infringer copied on purpose. A strong showing of intentional copying — internal emails, before-and-after design mockups, that kind of thing — tends to carry a lot of weight.

Steps to Take If You Suspect Infringement

Document everything first. Before you contact anyone, gather proof that your trade dress existed and was in use before the alleged copycat showed up — dated product photos, packaging mockups, sales records, marketing materials. Also collect examples of the competing product: photos, packaging, purchase receipts.

Get a trademark attorney involved early. Trade dress cases hinge on nuanced legal tests (distinctiveness, functionality, likelihood of confusion), and a lawyer who handles this regularly can tell you quickly whether you have a real claim or a weak one. Many offer an initial consultation before you commit to litigation costs.

Consider a cease-and-desist letter. This is often the first formal move. It puts the other side on notice, lays out your rights, and demands they stop using the confusing design. A surprising number of disputes end here, especially when the infringement wasn't deliberate — the other company may simply not have realized the overlap.

Look into a formal trademark registration, if you haven't already. Trade dress can be protected without federal registration, but registering it with the U.S. Patent and Trademark Office gives you a legal presumption of validity and ownership, which makes any future dispute easier to win. If your trade dress isn't registered yet, this is worth doing regardless of whether you're currently in a dispute.

Weigh a lawsuit. If a cease-and-desist doesn't work, you can file suit in federal court. Available remedies include an injunction (a court order stopping the infringing use), monetary damages, and in some cases the infringer's profits or your attorney's fees. Litigation is expensive and slow, so most attorneys will also explore settlement or mediation before recommending you go all the way to trial.

Think about timing. Courts don't look kindly on brand owners who sit on their rights for years and then sue. If you've noticed the infringement, don't let it drag on — delay can weaken your case and, in some circumstances, bar certain remedies entirely.

If You've Been Accused of Infringement

The flow of this works both ways. If you're on the receiving end of a cease-and-desist letter or lawsuit, don't ignore it, and don't assume the accusation is automatically valid either. A lot of trade dress claims fail because the design at issue turns out to be functional, generic, or just not similar enough to cause real confusion. An attorney can assess whether the claimant's trade dress even qualifies for protection before you agree to change anything.

The Bottom Line

Trade dress protects the overall commercial impression your product or business makes — not any single design element in isolation. If you suspect someone has copied that impression closely enough to mislead your customers, start by documenting your case, then bring in a trademark attorney to evaluate distinctiveness, functionality, and likely confusion before deciding whether a cease-and-desist letter or a lawsuit is the right next move.
