About Trademark Infringement
Trademark infringement occurs when a party uses a mark in commerce that is identical or confusingly similar to a registered or established trademark, creating a likelihood of confusion among consumers regarding the source, sponsorship, or affiliation of goods or services. Trademark infringement claims are primarily governed by the Lanham Act (15 U.S.C. §§ 1114 and 1125(a)), which provides remedies for both registered and unregistered marks. The central question in any trademark infringement case is whether the defendant's use of a mark is likely to cause consumer confusion — meaning that an appreciable number of ordinarily prudent consumers would believe the defendant's goods or services come from, are sponsored by, or are affiliated with the plaintiff.
Federal courts evaluate likelihood of confusion using a multi-factor test that varies slightly by circuit but generally considers: the strength of the plaintiff's mark, the similarity of the marks, the similarity of the goods or services, evidence of actual confusion, the defendant's intent, the quality of the defendant's goods, the sophistication of the consumers, and the likelihood of expansion into related markets. Beyond standard infringement, the Lanham Act also provides causes of action for trademark dilution (which protects famous marks against blurring or tarnishment even without consumer confusion) and cybersquatting (the bad-faith registration of domain names incorporating another's trademark).
Trademark infringement attorneys represent both plaintiffs seeking to protect their brand rights and defendants accused of infringement. The stakes in these cases can be substantial: successful plaintiffs may recover the defendant's profits, their own damages, attorney's fees in exceptional cases, and injunctive relief permanently prohibiting further infringement. Conversely, defendants may face costly injunctions requiring immediate rebranding. Early legal intervention is critical, as delay in enforcing trademark rights can result in a defense of laches or a finding of acquiescence.
Why You Need a Trademark Infringement Attorney
Trademark infringement poses a direct threat to brand value, consumer trust, and market position. When a competitor or counterfeiter uses a confusingly similar mark, consumers may be diverted from the legitimate brand, leading to lost sales and diminished customer relationships. Even if the infringing products are of comparable quality, the brand owner loses control over its reputation and the consumer experience associated with its mark. When infringing products are inferior, the damage is compounded as consumers mistakenly attribute poor quality to the legitimate brand.
The economic impact of trademark infringement is substantial. According to the International Trademark Association, counterfeiting and piracy are estimated to drain $4.2 trillion from the global economy annually by 2022. Beyond counterfeiting, garden-variety trademark infringement between legitimate businesses is equally costly, with federal trademark litigation averaging $375,000 to $2 million or more through trial. For brand owners, the failure to enforce trademark rights is not just a missed opportunity — it can constitute abandonment or acquiescence, permanently weakening the legal protections they have built.

Likelihood of Confusion Claims
Litigating cases where a competitor has adopted a mark that is confusingly similar to the plaintiff's mark for related goods or services, the core claim under the Lanham Act.
Counterfeiting Actions
Pursuing claims against parties who use identical or virtually indistinguishable copies of a registered trademark, often involving counterfeit goods sold online or through unauthorized channels.
Trademark Dilution Claims
Bringing claims under the Federal Trademark Dilution Act for owners of famous marks to prevent use that blurs the distinctiveness of or tarnishes the reputation of the famous mark.
Cybersquatting & Domain Name Disputes

Know Your Rights
- As a trademark owner, you have the right to prevent others from using confusingly similar marks in commerce for related goods or services, regardless of whether you have a federal registration.
- Federal registration creates a presumption of validity and ownership, and enables you to recover the infringer's profits, your actual damages, costs, and attorney's fees in exceptional cases.
- You can seek preliminary and permanent injunctive relief to stop ongoing infringement immediately, without waiting for a full trial on the merits.
- Under the Lanham Act, you may recover treble damages and attorney's fees in cases involving willful infringement or counterfeiting.
- You have the right to pursue both federal and state law claims for trademark infringement and unfair competition, providing multiple avenues for relief.
- If accused of infringement, you have the right to assert defenses including fair use, nominative use, parody, laches, and the first sale doctrine.
- You can report trademark counterfeiting to U.S. Customs and Border Protection and seek the seizure and destruction of infringing goods at the border.
What to Look for in a Trademark Infringement Attorney
Trademark infringement cases require an attorney with substantial litigation experience in federal court, as nearly all trademark infringement claims are brought under the federal Lanham Act. Look for an attorney who has handled cases from the initial cease-and-desist stage through trial and appeal, and who understands the multi-factor likelihood of confusion test applied in your particular federal circuit. Experience with preliminary injunction practice is critical, as temporary restraining orders and preliminary injunctions are common early-stage remedies in trademark cases.
Evaluate whether the attorney has experience on both the plaintiff and defense sides, as this provides a more well-rounded understanding of the strengths and weaknesses of infringement claims. Ask about their experience with e-commerce enforcement, UDRP proceedings, and customs recordation if your brand is affected by online infringement or counterfeiting. Consider whether the firm has the resources to handle discovery-intensive litigation and the willingness to pursue the case to trial if settlement negotiations fail.
Questions to Ask Your Trademark Infringement Attorney
- 1Have you litigated trademark infringement cases in the federal circuit where my case would be filed, and are you familiar with that circuit's likelihood of confusion test?
- 2What is your assessment of the strength of my infringement claim based on the facts presented, and what are the likely defenses?
- 3Do you recommend sending a cease-and-desist letter first, or is immediate litigation warranted given the circumstances?
- 4What is the estimated cost of this matter through each stage — cease-and-desist, early resolution, discovery, and trial?
- 5Do you have experience seeking preliminary injunctions in trademark cases, and what is required to obtain one?
- 6What damages am I likely to recover if successful, and is a contingency fee arrangement available?
- 7Can you help with e-commerce takedowns and platform enforcement in addition to formal litigation?
Understanding Trademark Infringement Legal Costs
Trademark infringement legal costs vary widely depending on the complexity of the case and whether it resolves early or proceeds to trial. Cease-and-desist letters and pre-litigation negotiations typically cost $2,000 to $10,000. UDRP domain name proceedings generally cost $3,000 to $8,000 including filing fees. Federal trademark litigation costs escalate significantly: through the discovery phase, costs typically range from $100,000 to $350,000, and through trial, the median cost is $375,000 to $2 million or more according to AIPLA surveys. Some attorneys handle trademark infringement cases on a contingency fee basis (typically 30-40% of any recovery), though hourly billing is more common. Defendants face similar cost ranges. The availability of attorney's fees in "exceptional cases" under the Lanham Act provides additional incentive for both sides to litigate in good faith.
