Trademark infringement occurs when someone uses a name, logo, or other brand identifier that is likely to cause confusion with yours — regardless of whether they knew about your mark or intended to copy it. In Louisiana, business owners face infringement in two distinct forms: someone in the local market using a similar name for a similar business, and national or online competitors whose use bleeds into Louisiana through digital channels. What you can actually do about it depends heavily on what kind of trademark rights you have, where the infringer is operating, and how aggressively you want to move. Most disputes never reach a courtroom — but the outcome of the ones that do almost always reflects the quality of the rights you built before the infringement happened.

The Likelihood of Confusion Standard

Federal trademark law uses a multi-factor test to determine whether infringement has occurred, and the central question is whether an ordinary consumer would likely be confused about the source of the goods or services. Courts apply factors including the similarity of the marks in appearance, sound, and meaning; the similarity of the goods or services; the channels of trade; and evidence of actual confusion.

For Louisiana business owners, the geographic market matters specifically. A restaurant in New Orleans that discovers a similarly named restaurant opened in Shreveport is dealing with a different analysis than one that discovers the name appearing on a competitor's website serving the same national customer base. In a world where every business has an online presence, geographic separation provides less protection than it once did.

Cease and Desist: The Starting Point, Not the End Point

The first step in most trademark disputes is a cease and desist letter — a formal written demand that the infringing party stop using the mark. A well-drafted letter identifies your rights, describes the infringing use specifically, and demands that the infringing party cease use, destroy infringing materials, and confirm compliance in writing.

Many infringements resolve at this stage. But cease and desist letters also have a secondary function: they establish that the infringer had notice of your rights. If litigation follows, continued use after receiving notice supports a finding of willful infringement — which opens the door to enhanced damages and attorney's fees under federal law.

Federal Court vs. Louisiana State Court for Trademark Claims

Federal trademark infringement claims under the Lanham Act are litigated in federal court. In Louisiana, the Eastern District covering New Orleans and the Western District covering Shreveport handle these cases. Federal courts have nationwide jurisdiction, can issue nationwide injunctions, and can award the infringer's profits, actual damages, and — for willful infringement — up to three times damages plus attorney's fees.

For businesses with only Louisiana state registrations — not federal registrations — enforcement is limited to Louisiana state courts and the geographic area where you have established common law rights. This is one of the most concrete reasons federal registration matters.

When You've Been Accused of Infringement

Receiving a cease and desist accusing you of infringing someone else's mark requires prompt, strategic response. The worst response is to ignore it. The second worst is to respond aggressively without first assessing whether the claims have merit.

When you receive a cease and desist, have trademark counsel assess the strength of the claimant's rights and the plausibility of the infringement claim. Many cease and desist letters are sent on weak foundations. The response — whether a negotiated rebrand, a licensing arrangement, a substantive rebuttal, or litigation — depends entirely on that assessment.

Frequently Asked Questions

Q: Can I sue for trademark infringement if I don't have a federal registration?

Yes. Common law trademark rights arise from use, and you can bring a state law infringement action in Louisiana state court without a federal registration. But your rights are geographically limited to where you've actually used the mark in commerce, and you don't have access to the Lanham Act's federal remedies.

Q: What damages are available in a trademark infringement case in Louisiana?

Under the Lanham Act in federal court: the infringer's profits, your actual damages, costs of the action, and — for willful infringement — up to three times damages plus attorney's fees. In state court actions, damages are typically limited to actual harm and, in some cases, injunctive relief.

Q: How quickly does a trademark infringement action move in federal court?

In the Eastern District of Louisiana, a trademark case on a standard track can take 18 to 36 months from filing to trial. Emergency injunctive relief can be obtained within days or weeks when the facts support it. Most cases settle before trial.

Q: What is trademark dilution and is it different from infringement?

Dilution is a separate federal claim for owners of famous marks — it protects against uses that blur the distinctiveness of the mark or tarnish its reputation, even without consumer confusion. For most Louisiana small business owners, infringement is the relevant claim.

If you've discovered someone using your brand — or you've received a cease and desist — schedule a consultation with BLG before you respond. What you do in the first 30 days of a trademark dispute often determines the outcome.
