Businesses invest time and money in names, logos, and other branding that customers associate with their products or services. Trademark infringement generally occurs when someone uses a mark in commerce in a way that is likely to confuse customers about the source, sponsorship, approval, or affiliation of goods or services.
The consequences can extend beyond a lost sale. Confusing branding may divert customers, undermine a company’s reputation, or lead customers to blame one business for another’s products or conduct. A business accused of infringement may face demands to change its name, withdraw products, revise advertising, or pay money damages.
For example, an established home-services company may discover that a new company serving the same area has adopted a similar name and logo. Customers begin calling the established company about work performed by the newcomer. Those circumstances may support an infringement claim, but similarity alone does not resolve the dispute. The strength of the claimed mark, each party’s rights, the services offered, and the way customers encounter the branding all matter.
What Does a Trademark Protect?
A trademark identifies and distinguishes the source of goods. A service mark performs the same function for services; the term “trademark” is often used to cover both. Protection may extend to business or product names, logos, slogans, and other distinctive identifiers.
Trademark law does not give a business ownership of a word for every purpose. Rights depend on the mark, the relevant goods or services, geographic scope, and other circumstances. Two businesses may sometimes use similar names without infringement when their uses are not likely to confuse customers.
Some disputes concern trade dress, meaning the source-identifying appearance of packaging, a product, or a business presentation. Trade dress has additional requirements, including that protected features cannot be functional. A company cannot use trademark law simply to prevent competitors from copying useful product features.
Does a Trademark Have to Be Registered?
Not always. Federal law provides a claim for infringement of federally registered marks, and it can also protect qualifying unregistered marks through claims addressing false designation of origin and misleading affiliation. An unregistered mark still must qualify for protection, and the claimant must establish the relevant rights.
Registration on the federal Principal Register provides important evidentiary benefits concerning validity, ownership, and the right to use the mark for the goods or services identified. It does not establish an unlimited right to stop all similar uses or guarantee success in an infringement lawsuit. Earlier users and other defenses may remain important. See 15 U.S.C. § 1114, 15 U.S.C. § 1115, and 15 U.S.C. § 1125(a).
Registering a company name with a state or obtaining a domain name is not the same as obtaining federal trademark registration. Nor does either step, by itself, establish that the name can be used without infringing someone else’s rights.
What Must Be Proven?
1. A Valid, Protectable Mark
The claimant must establish that the asserted name, design, or other identifier qualifies for trademark protection. Distinctiveness is central: does the designation identify a particular source, or does it merely describe the product or name the product category?
- Fanciful or arbitrary marks use invented terms or existing words unrelated to the goods or services. They can be inherently distinctive.
- Suggestive marks require some imagination to connect the mark with the product or service and can also be inherently distinctive.
- Descriptive terms directly describe a characteristic of the goods or services. They generally require acquired distinctiveness, also called secondary meaning: customers have come to associate the term with a particular source.
- Generic terms name the relevant category of goods or services and cannot receive trademark protection for that category.
A designation’s classification depends on its use in relation to the particular goods or services, not on the word in isolation. A business’s investment in advertising does not automatically make an otherwise unprotectable term exclusive property.
2. Ownership and Superior Rights in the Relevant Market
The claimant must establish its right to enforce the mark against the challenged use. Relevant evidence may include when and where the parties used their marks, registration and application records, assignments, licenses, and whether use continued.
Priority is not always resolved by asking who formed a company first or who first reserved a website address. Actual trademark use, federal filing rights, geographic scope, and the nature of each party’s use require examination.
3. Infringing Use in Commerce
The challenged use must meet the requirements of the applicable claim, including use in commerce in connection with goods or services. Disputes may involve product labels, business names, advertising, websites, online listings, or branding used after a license ends.
Not every reference to another business’s name is infringement. Identifying a product for a legitimate comparison, describing goods, and making a claim of affiliation raise different questions. The context and manner of use matter.
4. A Likelihood of Customer Confusion
The central question is whether the challenged use is likely to confuse customers about the source of the goods or services or a relevant business connection. The marks do not have to be identical, and confusion can involve mistaken sponsorship or approval rather than a belief that the businesses are literally the same company.
Intentional copying is not required for every infringement claim. A business may adopt a name without intending to mislead anyone and still face liability if the legal requirements are met. See 15 U.S.C. §§ 1114 and 1125(a).
How Do Courts Evaluate Likelihood of Confusion?
Courts consider multiple factors rather than simply placing two logos side by side. Depending on the governing court and circumstances, relevant considerations include:
- The strength of the claimed mark: how distinctive it is and how strongly customers associate it with a particular source.
- Similarity of the marks: their appearance, sound, meaning, and overall commercial impression as customers encounter them.
- Relatedness of the goods or services: whether customers could reasonably believe they come from the same source or connected businesses.
- Sales and advertising channels: whether the parties reach overlapping customers through similar stores, websites, advertising, or other channels.
- Purchasing conditions: the care and attention customers are likely to exercise.
- Intent: whether the challenged branding was adopted to trade on another business’s reputation or cause confusion.
- Evidence of actual confusion: misdirected orders, inquiries, complaints, or reliable survey evidence.
The factors and their weight vary by court and case. Evidence of actual confusion can be important, but a claimant need not necessarily wait until customers report mistakes before seeking relief. Conversely, isolated confusion does not automatically establish infringement. See George & Co. LLC v. Imagination Entertainment Ltd., 575 F.3d 383 (4th Cir. 2009).
What Defenses and Limitations May Apply?
A defendant may dispute whether the claimant owns enforceable rights, whether those rights cover the challenged market, or whether confusion is likely. Other issues may include:
- Earlier rights: the defendant may have priority or a protected area of prior use.
- Descriptive fair use: a term may be used fairly and in good faith to describe goods or services rather than as the defendant’s own trademark.
- Permission or licensing: the use may be authorized, although exceeding a license’s scope or continuing after termination can present different issues.
- Abandonment: the claimant may have lost rights through discontinued use without an intent to resume, or other conduct meeting the legal requirements for abandonment.
- Delay, consent, or reliance: unreasonable delay or conduct indicating acceptance may affect relief under doctrines such as laches, acquiescence, or estoppel.
These defenses have specific requirements. A disclaimer does not automatically cure confusing branding, and the fact that a business used its owner’s surname does not necessarily eliminate infringement risk. Even a registration that has become “incontestable” remains subject to specified defenses and still requires proof of infringement. See 15 U.S.C. § 1115.
How Does Infringement Differ from Counterfeiting, Dilution, and Cybersquatting?
These claims can overlap, but they are not interchangeable.
Counterfeiting concerns a narrower category of unauthorized imitation involving counterfeit marks as defined by statute. Not every confusingly similar name or logo is a counterfeit. Qualifying counterfeiting cases can support special remedies.
Trademark dilution concerns certain uses that impair the distinctiveness or harm the reputation of a qualifying famous mark. Federal dilution law requires fame among the general consuming public of the United States, not merely recognition in a local market or specialized industry. Unlike ordinary infringement, qualifying dilution does not require likely confusion.
Cybersquatting concerns specified domain-name conduct undertaken with a bad-faith intent to profit from another’s mark. Registering a similar domain does not automatically establish the claim; the statutory requirements and defenses must be evaluated. See 15 U.S.C. § 1125(c)–(d).
Damages and Other Civil Remedies
Proving infringement does not automatically establish entitlement to every remedy. The claim, the defendant’s conduct, the connection to the requested recovery, and equitable considerations all matter.
Actual Damages
These compensate for proven harm caused by infringement. Depending on the evidence and applicable standards, recovery may include lost profits from diverted sales, injury to business goodwill, or qualifying corrective-advertising expenses.
The claimant must provide a supported basis for calculating the loss. Gross revenue is not the same as profit, and a decline in sales does not establish that infringement caused every lost dollar. Speculative reputational harm or an unsupported demand for the cost of an entire rebranding effort does not automatically establish recoverable damages.
The Defendant’s Profits
A court may award profits attributable to infringement, subject to the applicable legal standards and principles of equity. This differs from compensating the claimant for its own losses. It does not mean the claimant automatically receives all revenue earned by the defendant.
For infringement under Section 1125(a), willfulness is not an absolute prerequisite to a profits award, although the defendant’s state of mind remains highly important. See Romag Fasteners, Inc. v. Fossil, Inc., 140 S. Ct. 1492 (2020).
The proper defendant also matters. A court cannot simply combine a defendant’s profits with those of separately incorporated affiliates that are not parties to the suit by treating them as one enterprise. See Dewberry Group, Inc. v. Dewberry Engineers Inc., 145 S. Ct. 681 (2025).
Increased Damages and Special Counterfeiting Remedies
Federal law permits certain adjustments to monetary awards, including an increase of actual damages up to three times the amount found, depending on the circumstances. Under the ordinary adjustment provision, the award must be compensatory rather than a penalty; infringement does not automatically create a separate punitive-damages award.
Qualifying counterfeiting claims have different rules. These can include treble profits or damages and attorney’s fees for specified intentional, knowing conduct, absent extenuating circumstances. A claimant may instead elect statutory damages in qualifying counterfeit-mark cases, rather than recovering actual damages and profits under the ordinary provision. Statutory damages are not generally available merely because ordinary trademark infringement has occurred. See 15 U.S.C. § 1117(a)–(c).
Injunctions
An injunction is a court order requiring someone to do—or stop doing—something. Relief may prohibit infringing branding and require changes to advertising, labels, signage, or online materials. The scope depends on the violation and the requirements for relief.
Federal trademark law provides a rebuttable presumption of irreparable harm after the required finding of a violation for permanent relief, or likely success on the merits for preliminary relief. A rebuttable presumption can be challenged with contrary evidence; it does not make an injunction automatic. See 15 U.S.C. § 1116(a).
Attorney’s Fees and Court Costs
Federal law permits reasonable attorney’s fees to the prevailing party in exceptional cases. Ordinary success in an infringement suit does not automatically satisfy that standard. Recoverable court costs are distinct from attorney’s fees and do not necessarily include every expense incurred in the dispute. Special counterfeiting provisions may impose different fee rules. See 15 U.S.C. § 1117.
Overlapping remedies do not permit duplicate recovery for the same injury. State-law claims, if applicable, require their own analysis.
What Evidence Matters?
Important evidence may include trademark registrations and applications, dated examples of use, sales and advertising records, licenses, assignments, and documents showing the geographic scope of each business’s activities.
Screenshots, packaging, advertisements, marketplace listings, and customer communications can show how the marks appeared in the market. Records of misdirected orders, inquiries, or complaints may help assess confusion. Financial records may be necessary to connect infringement to losses or profits.
Both sides should preserve relevant materials, including earlier versions of websites and branding. A business should not delete disputed advertising or communications without preserving the evidence and considering its legal obligations.
What If a Business Receives a Cease-and-Desist Letter?
A demand letter is an allegation, not a court ruling. The recipient should evaluate the claimed rights, the particular use being challenged, the supporting evidence, and the requested response before agreeing to stop using a name or pay money.
A dispute may be resolved through changes to branding, limits on particular uses, a license, a coexistence agreement, or another negotiated solution. Whether those options make sense depends on the strength of the parties’ positions and their business goals. A recipient should not assume that changing a logo, adding a disclaimer, or obtaining its own registration will necessarily resolve the problem.
How Quickly Should a Business Act?
Prompt evaluation can help preserve evidence, prevent further confusion, and assess whether emergency relief is appropriate. Delay may affect available relief, including through laches—a defense involving unreasonable delay that prejudices the other party.
The deadline analysis depends on the claims, the relevant court, and the conduct at issue. Businesses should not assume that all trademark claims have a single nationwide filing period or that continued use automatically eliminates the consequences of delay.
