Enforcing Your Trademark Rights

By Hank FasthoffJune 9, 2026

A federal registration strengthens enforcement, but it doesn't convert every similar use into infringement. The registration covers the mark and the listed goods or services, subject to territorial rights, statutory defenses, and other limits. Liability ordinarily depends on how the parties use their marks and whether consumers are likely to be confused.

Monitoring Applications and Marketplace Use

A trademark watch service may identify applications and published marks that a manual search misses. Monitoring the Trademark Official Gazette allows an owner to assess whether to request an extension or file an opposition during the statutory period. A watch limited to USPTO records won't identify unregistered uses.

Marketplace monitoring may include ecommerce listings, paid search advertisements, social media accounts, domain names, industry directories, trade publications, and trade show materials. The appropriate scope depends on the goods or services, territories, sales channels, customers, and ways in which unauthorized use would cause harm.

Evidence may disappear after the owner contacts a seller or platform. Before sending a demand, the owner may need dated screenshots, complete URLs, account information, advertising, product photographs, packaging, communications, and a lawfully acquired sample. The file should distinguish information observed directly from assumptions about the seller, source, volume, or intent.

Assessing the Use Before Acting

A similar word or design doesn't establish infringement by itself. The assessment includes ownership and priority, the registration's status and scope, similarity between the marks, the relationship between the goods or services, sales channels, consumers, market conditions, and the likelihood of confusion under the governing circuit's factors.

Possible defenses are also part of the first review. A challenged party may assert descriptive fair use, nominative fair use, prior use in a limited territory, abandonment, acquiescence, license, or a protected expressive or noncommercial use. An incontestable registration narrows certain challenges but doesn't eliminate every defense under Section 33(b).

The business objective affects the response. An exact counterfeit, a confusing product listing, a new application, a critical reference to the brand, and a domain name held for resale present different legal and commercial questions. The response should address the conduct that threatens the mark without claiming rights beyond the available evidence.

Cease and Desist Letters

Trademark law doesn't require a cease and desist letter before suit. In many disputes, a letter provides an efficient opportunity to end or limit the challenged use. In others, advance notice may prompt a declaratory judgment action, destruction of evidence, transfer of assets, or movement of counterfeit inventory.

A demand ordinarily identifies the asserted rights, the challenged conduct, the legal basis for the objection, the requested action, and a response deadline. Depending on the record, the requested action may include stopping use, changing packaging or trade dress, transferring a domain name or social media account, preserving evidence, identifying suppliers, or accounting for sales.

The letter should separate confirmed facts from allegations and avoid remedies the law doesn't support. Its tone should reflect the evidence, urgency, recipient, and desired resolution rather than a fixed template. Communications made before suit may later appear in a complaint, declaratory judgment record, fee request, or settlement dispute.

Negotiated Resolutions

A negotiated resolution may require an immediate stop, a limited selloff, a transition period, geographic or product restrictions, changes to trade dress, transfer of online assets, or a license. The agreement should define the marks, goods or services, territories, channels, deadlines, quality controls, existing inventory, and consequences of breach.

Consent and coexistence agreements serve different purposes depending on their terms. Parties may submit a consent agreement to the USPTO when responding to a likelihood of confusion refusal, but the agency isn't bound to accept their conclusion. A private coexistence agreement may allocate use between the parties even when no application is pending.

A settlement that permits continuing use requires attention to trademark quality control. An uncontrolled trademark license may impair the owner's rights. The agreement should therefore state the standards and oversight that apply when one party authorizes the other to use the mark.

TTAB Proceedings Address Registration

An owner may oppose a pending application or seek cancellation of an existing registration before the Trademark Trial and Appeal Board. Those proceedings may protect the federal register and remove a cited registration, but the Board can't order a party to stop using a mark or award damages.

When marketplace use and registration both require attention, the owner may need a federal court claim, a Board proceeding, or coordinated proceedings. The article on TTAB opposition and cancellation proceedings explains the available grounds, deadlines, and limits on the Board's authority.

Federal Trademark Litigation

Section 32 of the Lanham Act addresses specified unauthorized uses of registered marks that are likely to cause confusion, mistake, or deception. Section 43(a) also covers specified false designations and misleading representations involving unregistered marks or trade dress. The claimant bears the burden of establishing each element of the asserted claim.

A preliminary injunction may stop challenged conduct while the case proceeds. The movant must satisfy the governing requirements for likelihood of success, irreparable harm, the balance of equities, and the public interest. Under Section 34(a), a finding of likely success on an identified Lanham Act violation establishes a rebuttable presumption of irreparable harm for a preliminary injunction or temporary restraining order.

Section 35(a) permits recovery, subject to statutory limits and principles of equity, of the defendant's profits, damages sustained by the plaintiff, and costs. A court may award reasonable attorney fees to the prevailing party in an exceptional case. Available relief depends on the claim, evidence, equitable considerations, and limits elsewhere in the Lanham Act.

In Romag Fasteners, Inc. v. Fossil, Inc., 590 U.S. 212 (2020), the Supreme Court held that willfulness isn't an absolute prerequisite to an award of the defendant's profits under Section 43(a). The defendant's mental state remains an important consideration when the court selects an equitable remedy.

Counterfeiting has separate remedial provisions. Instead of profits and damages under Section 35(a), the plaintiff may elect statutory damages from $1,000 to $200,000 per counterfeit mark per type of goods or services. The maximum increases to $2 million per counterfeit mark per type of goods or services when the court finds willful use.

Platform Reports Operate Under Private Rules

Major ecommerce and social media platforms provide reporting systems for trademark complaints. These procedures operate under each platform's policies and don't replace a court's infringement analysis. A report may remove a listing or restrict an account, but the platform may reject the report, request more information, or restore content after a response.

The owner should preserve the listing and related evidence before submitting a report. The complaint should identify the relevant registration, explain the challenged use accurately, and avoid treating criticism, resale, compatibility references, or other lawful uses as counterfeiting. Platform terms and applicable law govern the consequences of an erroneous or bad faith report.

Domain Name Disputes

The Uniform Domain Name Dispute Resolution Policy requires the complainant to establish three elements. The domain name must be identical or confusingly similar to a mark in which the complainant has rights, the registrant must lack rights or legitimate interests, and the domain must have been registered and must be used in bad faith. A UDRP panel may order transfer or cancellation, but it can't award money or enjoin conduct outside the domain registration.

The Anticybersquatting Consumer Protection Act requires a bad faith intent to profit and other statutory elements under Section 43(d). A successful claimant may elect statutory damages from $1,000 to $100,000 per domain name. The article on the UDRP domain name dispute process compares the administrative procedure with an ACPA action.

Customs Recordation

A trademark on the USPTO's Principal Register may qualify for recordation with U.S. Customs and Border Protection through its electronic recordation system. Marks on the Supplemental Register don't qualify. Recordation supplies CBP with information it can use when examining imported merchandise for goods bearing counterfeit or infringing recorded marks.

Gray market protection requires a separate analysis. CBP's current guidance describes protection when the United States and foreign marks have different owners that aren't under common ownership or control. When common ownership or control exists, the owner may request Lever rule protection for goods that are physically and materially different from authorized United States goods and satisfy the agency's requirements.

Recordation doesn't replace marketplace monitoring or litigation. The owner must maintain the federal registration and CBP recordation, provide useful product and supply chain information, and update ownership or contact records when required.

Enforcement Priorities and Delay

Trademark law doesn't require an owner to pursue every unauthorized reference or remote use. Enforcement priorities should reflect the likelihood of confusion, proximity to the owner's market, scale, consumer harm, counterfeiting, expansion plans, available evidence, and cost of the response. Documenting those decisions helps the owner apply the same criteria as new uses appear.

Delay can nonetheless affect relief against a particular defendant through defenses such as laches or acquiescence. Widespread third party use may also narrow the strength or scope attributed to a mark, depending on the nature and extent of that use. Neither principle means that tolerance of one unrelated use forfeits the mark or compels immediate litigation against everyone.

An enforcement program works best when monitoring, evidence preservation, legal analysis, business priorities, and follow through operate together. Registration supplies valuable presumptions and remedies, but disciplined decisions determine how well those tools protect the brand.
