Trademark Lawyers in NYC : Infringement Defense & Strategy

Trademark infringement occurs when a party uses a mark that is identical or confusingly similar to a registered or unregistered trademark in a way that is likely to deceive consumers about the source of goods or services. The Lanham Act, 15 U.S.C. § 1127, establishes federal protection and remedies. State common law also provides rights to owners of unregistered marks, though federal registration creates a presumption of ownership and validity that significantly strengthens enforcement. Courts evaluate infringement using a multifactor test that weighs the strength of the mark, similarity of the marks, relatedness of goods or services, and evidence of actual confusion. In practice, these cases are rarely as clean as the statute suggests; judges exercise considerable discretion in weighing factors, and outcomes often turn on how a court perceives the likelihood that consumers will be confused.

Liability extends beyond direct competitors. A company selling entirely different products can still infringe if its mark dilutes a famous brand or creates false association. Damages for infringement range from statutory damages of $1,000 to $200,000 per violation (or treble damages for willful infringement) to actual profits and costs. Injunctive relief is also available, which can require a defendant to cease use, rebrand, or destroy infringing materials. The financial exposure and operational disruption make early assessment critical.

A cease-and-desist letter is often the first formal notice of an infringement claim. Many businesses panic or ignore the letter entirely, both of which create legal risk. Ignoring a letter does not make the claim disappear; it may prompt litigation. Responding hastily without counsel can constitute an admission or waive defenses. The appropriate response depends on the merits of the claim, your business's use of the mark, and your risk tolerance. Counsel should evaluate whether your use qualifies as a fair use defense, whether the claimant's mark is actually valid and enforceable, and whether settlement or continued use is strategically sound. For trademark infringement claims, the first 30 days are critical; a well-crafted response (or strategic silence followed by negotiation) can set the tone for the entire dispute.

Several defenses and counterclaims can significantly alter the trajectory of an infringement dispute. Fair use (nominative use of a competitor's mark for comparison or descriptive use of a term) is a recognized defense if your use is not likely to cause confusion. Abandonment is another defense; if the claimant has not used the mark in commerce for three consecutive years, the mark may be vulnerable to cancellation. Genericness (the mark has become a common term for the category of goods) also defeats infringement claims. Counterclaims for cancellation of the claimant's registration or fraud in the USPTO application are common and can shift the entire case dynamics. Counsel experienced in trademark infringement suits will evaluate whether your facts support any of these defenses and whether pursuing a counterclaim is strategically advantageous.

Infringement damages are calculated using several methods. Actual damages include lost profits or unjust enrichment (profits the defendant earned from infringing use). Statutory damages, available only for registered marks, range from $1,000 to $200,000 per violation; willful infringement can triple this amount. Courts also award attorney fees in exceptional cases. Injunctive relief (an order to cease use and, in some cases, destroy infringing materials) is often the remedy most feared by defendants because it can shut down product lines or require rebranding. Settlement often involves a covenant not to sue, a license agreement, or a geographic or product-line limitation on use. Understanding the range of potential damages early helps inform whether settlement or litigation is the better path.

As counsel, I often advise clients that settlement early in the dispute, before discovery costs mount, is frequently more cost-effective than trial. However, the decision to settle depends on your assessment of liability risk, the strength of available defenses, and the business impact of the claimant's mark on your operations. If you face an infringement claim, evaluate whether the claimant's mark is truly strong (famous, distinctive, registered) and whether your use is genuinely likely to confuse consumers or whether the claim is overreaching.

Whether you are defending an infringement claim or seeking to protect your own mark, several strategic considerations should guide your next actions. First, conduct a comprehensive trademark audit to identify marks you own, their registration status, and renewal deadlines. Second, if you receive a cease-and-desist letter, do not respond without counsel; allow time for evaluation. Third, consider whether federal registration of your mark is necessary to strengthen your position in the marketplace and in potential disputes. Fourth, monitor the marketplace for unauthorized use of your mark, and document any instances for potential enforcement. Finally, if you are in an active dispute, evaluate early whether mediation or negotiation can resolve the matter more efficiently than protracted litigation. The goal is to protect your brand while managing legal costs and operational risk.
