how do you resolve trademark infringement — intellectual property law and protection

The short answer is that resolution almost never starts in a courtroom. How do you resolve trademark infringement in practice? By grading the threat, choosing the forum that matches it, and reserving litigation for the cases where nothing cheaper will stop the use.

Trademark infringement is one of the most serious threats a brand can face. When a third party uses a mark that is identical or confusingly similar to yours without authorization, in connection with similar goods or services, they may be infringing on your trademark rights. Understanding what constitutes trademark infringement and knowing how to respond effectively is essential for every business owner. PerspireIP helps clients identify infringement and take swift, strategic action to protect their brands.

What Is Trademark Infringement?

Trademark infringement occurs when a person or entity uses a trademark that is identical or confusingly similar to a protected mark in commerce, in connection with the sale, offering for sale, distribution, or advertising of goods or services, in a way that is likely to cause consumer confusion, mistake, or deception as to the source, sponsorship, or affiliation of the goods or services.

The key legal test for trademark infringement is likelihood of confusion — courts analyze whether an ordinary consumer encountering both marks is likely to be confused about the commercial source of the goods or services. This analysis involves multiple factors including the similarity of the marks, the similarity of the goods or services, the strength of the plaintiff’s mark, and evidence of actual confusion.

Common Examples of Trademark Infringement

Trademark infringement takes many forms in the modern business environment.

  • A competitor using a business name that is nearly identical to your registered trademark in the same industry
  • A website using your brand name as a domain name to sell competing products
  • A manufacturer producing counterfeit goods bearing your trademark without authorization
  • An online seller using your brand name in product titles or descriptions to draw traffic
  • A social media account posing as your brand to deceive consumers
  • A company using a logo that is visually similar to yours for related products or services

Trademark Infringement vs Counterfeiting

Trademark infringement and counterfeiting are related but distinct concepts. Trademark infringement involves the use of a confusingly similar mark that may not be identical to the original. Counterfeiting involves the use of a mark that is identical or substantially indistinguishable from a registered mark, typically on goods or services of the same type. Counterfeiting is a more serious offense and can result in criminal prosecution in addition to civil liability.

The Trademark Counterfeiting Act imposes criminal penalties including fines up to $2 million and imprisonment up to ten years for first-time offenders. Civil remedies for counterfeiting include treble damages and attorney’s fees in addition to standard infringement remedies. PerspireIP works with clients facing counterfeiting situations to coordinate both civil enforcement and, where appropriate, criminal referrals to law enforcement.

Defenses to Trademark Infringement Claims

Not every use of a similar mark constitutes trademark infringement. Several defenses may be available depending on the circumstances.

  • Fair Use: Descriptive fair use allows use of a term in its descriptive sense; nominative fair use allows use of another’s mark to refer to that brand’s products or services
  • Prior Use: A party who was using a mark in a geographic area before the trademark owner’s registration may have prior rights in that area
  • Abandonment: If the trademark owner has abandoned the mark, the registration may not be enforceable
  • No Likelihood of Confusion: The marks or goods and services are sufficiently different that confusion is unlikely
  • Functionality: Features that are functional cannot be protected as trademarks

How to Respond to Trademark Infringement

When you discover trademark infringement, the appropriate response depends on the severity and nature of the situation. PerspireIP recommends the following general approach when infringement is detected.

First, document the infringement thoroughly. Capture screenshots, purchase infringing products if possible, and gather evidence of the infringer’s commercial activities. This documentation will be essential if legal action becomes necessary. Second, assess the severity of the infringement — is it causing immediate harm to your business or reputation? Is it isolated or widespread? This assessment informs the urgency and nature of your response.

Cease and Desist Letters for Trademark Infringement

For most trademark infringement situations, the first formal step is sending a cease and desist letter. This letter notifies the infringer of your trademark rights, identifies the specific infringement, and demands that they stop using the infringing mark within a specified period. A well-drafted cease and desist letter can resolve many infringement situations without litigation.

PerspireIP drafts cease and desist letters that are firm but professionally calibrated to achieve the desired outcome. An overly aggressive letter can drive the infringer to seek a declaratory judgment that your mark is invalid, while an overly soft letter may not be taken seriously. The tone and content of the letter should be tailored to the specific circumstances.

Trademark Infringement Litigation

When a cease and desist letter does not resolve the trademark infringement, litigation in federal court may be necessary. Trademark infringement cases are heard in federal district courts under the Lanham Act. Remedies available in trademark infringement cases include injunctive relief ordering the infringer to stop using the mark, monetary damages including the infringer’s profits and the trademark owner’s lost profits, treble damages for willful infringement, and attorney’s fees in exceptional cases.

Litigation is expensive and time-consuming, but sometimes necessary to protect a valuable brand. PerspireIP coordinates with experienced trademark litigation counsel to provide clients with comprehensive enforcement support.

Documenting and Proving Trademark Infringement

When you discover potential trademark infringement, the quality of your documentation can make the difference between a successful enforcement action and a failed one. Courts and opposing counsel will scrutinize the evidence you gathered, and evidence that was not properly documented may be inadmissible or carry little weight. PerspireIP advises clients on best practices for documenting infringement from the moment they first discover a potential violation.

The most important rule is to document first, act second. Before you contact the infringer, send a cease and desist letter, or take any other action, thoroughly document the infringement. Take screenshots of all relevant web pages, social media posts, product listings, and other online evidence, making sure to capture the URL, date, and time of each screenshot. If the infringer is selling physical goods, purchase a sample if possible — this creates authenticated physical evidence of the infringing goods.

For online evidence, consider using a web archiving service like the Internet Archive’s Wayback Machine or a commercial archive service to create a permanent, timestamped record of the infringing content. Infringers often remove infringing content quickly once they become aware of a trademark owner’s interest, so creating a permanent archive before contacting them preserves critical evidence. Screenshots alone can be challenged as having been altered, while third-party archives provide more reliable documentary evidence.

Keep a detailed log of all evidence gathered, all steps taken, and all communications relating to the trademark infringement situation. This log should include dates, times, the nature of each infringement observed, and any responses to your enforcement efforts. A well-maintained enforcement log demonstrates the scope and persistence of the infringement and your good faith efforts to stop it — factors that courts consider when deciding whether to award enhanced damages or attorney’s fees in trademark infringement cases.

Trademark Infringement and Brand Reputation Management

Trademark infringement does not only cause legal and financial harm — it can cause significant reputational damage that is harder to quantify but equally serious. When consumers encounter inferior goods bearing your trademark, they may blame you for the inferior quality. When a company with a similar name engages in unethical business practices, your brand may be unfairly associated with those practices. Managing the reputational dimensions of trademark infringement requires both legal action and proactive public communications.

When significant trademark infringement is detected — particularly counterfeit goods or impersonation schemes that could deceive consumers — consider whether public communications are appropriate to protect your brand reputation. A clear statement on your website and social media channels explaining how to identify authentic products, warning consumers about counterfeits, and providing a way for consumers to verify authenticity can reduce the reputational harm caused by infringers while demonstrating your commitment to consumer protection.

PerspireIP coordinates with clients’ marketing and communications teams to ensure that trademark enforcement actions and public communications about infringement are aligned and consistent. Our goal is not only to achieve legal outcomes but to protect and restore the brand’s reputation in the marketplace. This holistic approach to trademark infringement response — combining legal enforcement with strategic communications — delivers the most complete protection for our clients’ brands.

International Trademark Infringement Challenges

Trademark infringement in international markets presents unique enforcement challenges because trademark rights are territorial — your US trademark registration does not give you enforcement rights in other countries. To enforce against infringement in a foreign market, you need trademark rights in that jurisdiction. This is why building an international trademark portfolio in key markets is so important before infringement occurs rather than after.

When infringement occurs in a foreign market where you have a registered trademark, enforcement requires working with local counsel familiar with that country’s trademark enforcement procedures. The remedies available, the burden of proof, the cost of enforcement, and the time to resolution all vary significantly by jurisdiction. PerspireIP coordinates international trademark enforcement through our global network of local counsel, managing the overall strategy from our US base while leveraging local expertise for each jurisdiction’s specific enforcement procedures. Contact PerspireIP today if you are experiencing trademark infringement in international markets — the sooner you act, the more enforcement options you have available.

The Statutory Basis for a Trademark Infringement Claim

Before deciding how do you resolve trademark infringement in a particular case, it is worth being precise about which statute the claim actually rests on, because the answer shapes both the evidence you need and the remedies available.

  • Section 32 of the Lanham Act (15 U.S.C. § 1114) — infringement of a federally registered mark. The registration is prima facie evidence of validity, ownership and the exclusive right to use the mark for the goods listed, which removes a whole layer of proof from the case.
  • Section 43(a) (15 U.S.C. § 1125(a)) — false designation of origin. This is the route for unregistered marks and for trade dress, and it is why a business with no registration is not without a remedy. The price is that you must prove the mark is distinctive and protectable, and for unregistered trade dress that it is non-functional.
  • Section 43(c) (15 U.S.C. § 1125(c)) — dilution by blurring or tarnishment, available only to owners of marks that are famous in the sense of being widely recognised by the general consuming public of the United States. This is a narrow gate, and most well-known regional brands do not pass through it.

The practical consequence is that registration status changes the shape of the dispute rather than the existence of a right. An unregistered claimant is not barred, but will spend time and money establishing what a registrant gets by presumption.

Likelihood of Confusion: Federal Court and the TTAB Are Not the Same Forum

Both a district court and the Trademark Trial and Appeal Board will ask whether confusion is likely, but they are answering different questions. A court decides whether the defendant’s use infringes. The Board decides whether a mark should be registered. A party can lose at the Board and continue trading, or win a registration and still be enjoined.

The factor tests differ by forum and by circuit. The TTAB applies the DuPont factors. The Second Circuit applies the Polaroid factors; the Ninth Circuit applies the Sleekcraft factors. The headings overlap heavily — similarity of the marks, proximity of the goods, strength of the senior mark, evidence of actual confusion, the defendant’s intent, purchaser sophistication — but the weight given to each varies, and which circuit you are in genuinely affects the odds.

The two forums are not hermetically sealed from one another. In B&B Hardware, Inc. v. Hargis Industries, Inc. (2015), the Supreme Court held that a TTAB finding on likelihood of confusion can have issue-preclusive effect in later infringement litigation, provided the usages adjudicated by the Board are materially the same as those before the court. That decision raised the stakes of opposition and cancellation proceedings considerably: a proceeding once treated as a low-cost registry skirmish can now bind you in court.

Remedies: Injunctions, Profits, and the Romag Rule on Willfulness

The remedy you can realistically obtain should drive the strategy from the first letter, not be discovered at the end of it.

  1. Injunctive relief under 15 U.S.C. § 1116. For most brand owners this is the point of the exercise — stopping the use matters more than collecting money — and a preliminary injunction can effectively end the dispute.
  2. Monetary relief under 15 U.S.C. § 1117(a): the defendant’s profits, any damages sustained, and the costs of the action, with discretion to enhance damages and to award attorney fees in exceptional cases.
  3. Statutory damages for counterfeiting under § 1117(c), which allow recovery without proving actual loss — often the only workable route against anonymous or offshore sellers.

One recent change matters a great deal to settlement value. In Romag Fasteners, Inc. v. Fossil Group, Inc. (2020), a unanimous Supreme Court held that a finding of wilfulness is not an absolute precondition to an award of the infringer’s profits under § 1125(a). Several circuits had previously imposed that requirement. Wilfulness remains highly relevant to the court’s discretion, but it is no longer a threshold the plaintiff must clear, and an innocent-infringement defence is correspondingly weaker than it was.

Resolving Infringement Without Filing Suit

Most infringement is resolved commercially, and the question of how do you resolve trademark infringement efficiently usually has an answer well short of a federal complaint.

  • A calibrated demand letter. The risk of an aggressive one is that it hands the recipient standing to file a declaratory-judgment action in their home forum, taking control of venue away from you. Tone and specificity are tactical choices, not stylistic ones.
  • A coexistence or consent agreement. Where the parties genuinely operate in different channels or territories, a written allocation of goods, geography and presentation resolves the conflict and can simultaneously clear a Section 2(d) refusal at the USPTO.
  • Opposition or cancellation at the TTAB. Cheaper than litigation and aimed at the registration rather than the use — but, after B&B Hardware, capable of producing findings that follow you into court.
  • Platform enforcement. Marketplace brand-protection programmes and registrar complaints remove listings far faster than any court, though they address symptoms rather than the underlying use.
  • UDRP proceedings for abusive domain registrations, which are quick and inexpensive but limited to transfer or cancellation of the domain.

Delay is the one strategy with no upside. Laches and acquiescence are live defences, and a brand owner who has tolerated a use for years will find both the injunction and the profits award harder to obtain.

How Do You Resolve Trademark Infringement Across Borders?

Trademark rights are territorial. A U.S. registration gives you nothing in Germany, and a party using your brand in a market where you hold no rights is, as a matter of law, frequently not infringing anything at all. That reframes the question entirely once a dispute crosses a border.

The first step is almost never enforcement — it is establishing whether you hold a right in the relevant jurisdiction. The Madrid Protocol allows a single international application, based on a home registration or application, to seek extension of protection in the member countries you designate. It is administratively efficient, but for the first five years the international registration remains dependent on the home mark, so a successful attack on the base registration can bring the whole structure down. That is the so-called central attack, and the remedy is transformation into national applications within a defined window.

Where rights do exist abroad, the practical toolkit differs from the U.S. one:

  • Customs recordation. Recording a registration with U.S. Customs and Border Protection — and with the equivalent authorities in other markets — stops counterfeit goods at the border, which is usually far more effective than pursuing the overseas manufacturer.
  • The EUIPO route. A single EU trade mark covers all member states, but it is equally vulnerable as a unitary right: a successful attack in one state can take down the whole registration.
  • First-to-file jurisdictions. In many markets, prior use counts for little and the registry decides. Trademark squatting is a genuine commercial risk, and the cure — buying the mark back — is usually cheaper than the litigation.

So how do you resolve trademark infringement in a market you never filed in? Realistically, by filing first and enforcing second, and by treating the filing programme as the enforcement strategy rather than a separate exercise. The brands that handle cross-border infringement well are the ones that registered ahead of expansion rather than in response to a problem.
