Introduction: The Stakes in Protecting Your Brand

Your brand is more than a name or logo. It’s the hard-won trust of customers, the goodwill built over years, and the identity that sets you apart from competitors. When another business infringes your trademark—whether by deliberate counterfeiting or careless similarity—they’re not just borrowing your reputation; they’re diluting your identity and stealing your market share. Trademark infringement litigation is the tool trademark owners use to protect and vindicate their rights.

At DeepLaw, we represent trademark owners—plaintiffs—who need both strategic judgment and courtroom muscle to enforce their rights. From the first demand letter to treble damages after trial, we guide you through the litigation process with empathy, expertise, and determination.

Pre-Litigation: Demand Letters and Early Resolution

The first move in many infringement disputes isn’t filing a complaint, but sending a demand letter (sometimes called a cease-and-desist letter). This letter puts the infringer on notice of your rights and demands that they stop their unlawful use. A well-crafted demand letter:

• Identifies your registered (or common law) mark

• Describes the infringing conduct

• Explains the legal consequences of continued infringement

• Offers a chance for voluntary compliance before litigation

Sometimes, infringers back down quickly; other times, they dig in. Either way, the demand letter is the foundation of your claim—and can set the tone for everything that follows.

Filing the Complaint: Taking It to Court

If a demand letter doesn’t resolve the dispute, the next step is filing a complaint in federal court. Federal jurisdiction is proper for almost all trademark cases because trademarks are governed by the Lanham Act (15 U.S.C. §§ 1051 et seq.). The complaint:

• Alleges ownership of the valid trademark

• Sets out the infringer’s unlawful conduct

• Asserts causes of action (e.g., trademark infringement, unfair competition, dilution)

• Demands relief (injunctions, damages, attorneys’ fees)

The defendant then has the chance to respond, often raising defenses like fair use, abandonment, or non-likelihood of confusion. The early pleadings stage defines the battlefield.

Discovery: Digging for the Truth

Once the case begins, discovery is where the real work happens. Plaintiffs can demand documents, emails, marketing plans, and sales data from the defendant to prove infringement and damages. Discovery tools include:

• Document requests: Marketing, advertising, and sales records

• Interrogatories: Written questions to clarify facts

• Depositions: Oral questioning of witnesses under oath

• Expert reports: Analysis of confusion, consumer surveys, and economic damages

Discovery is often where defendants are forced to reveal just how much they benefited from their misuse of your mark—and how much it cost you.

Expert Witnesses: The Science of Confusion

Trademark cases frequently hinge on likelihood of confusion—would ordinary consumers think the defendant’s goods or services come from you? Expert witnesses can make or break these issues:

• Survey experts: Design and interpret consumer surveys

• Marketing experts: Assess brand strength and reputation

• Economic experts: Quantify damages and disgorgement of profits

The credibility and clarity of these experts can be decisive in persuading judges and juries.

Briefing and Motions: Legal Strategy in Action

Trademark litigation isn’t only about facts; it’s also about law. Both sides file motions to shape the case:

• Motions to dismiss: Challenge the sufficiency of your claims

• Summary judgment motions: Argue there’s no dispute of fact and one side should win as a matter of law

• Daubert motions: Attempt to exclude unreliable expert testimony

Plaintiffs must balance aggressive advocacy with strategic timing, always keeping the endgame in mind.

Trial: Telling Your Brand’s Story

If the case goes to trial, your lawyers must become storytellers. Trials are where you humanize your brand and show the jury why your trademark matters. Plaintiff’s trial strategy includes:

• Presenting evidence of your trademark’s strength and recognition

• Showing side-by-side comparisons of your mark and the infringer’s use

• Calling consumers or distributors to testify about actual confusion

• Demonstrating your investment in building goodwill

The goal: convince the factfinder that the infringer not only copied, but also caused harm that deserves redress.

Damages: The Rewards of Vindication

Trademark owners who prevail in court may recover:

• Actual damages: Compensation for lost sales, reputational harm, and corrective advertising

• Defendant’s profits: Disgorgement of the infringer’s unjust gains

• Treble damages: Tripling of damages for willful infringement (15 U.S.C. § 1117)

• Attorneys’ fees: Awarded in “exceptional cases” of deliberate or egregious conduct

• Injunctive relief: Court orders stopping the infringing conduct and sometimes requiring corrective measures

These remedies aren’t just about money—they’re about restoring balance and deterring others from infringing.

Empathy for Plaintiffs: Protecting the Heart of Your Business

For trademark owners, litigation isn’t abstract. It’s personal. Every day of infringement chips away at what you’ve built: your reputation, your customer trust, your unique place in the market. We understand the frustration, the indignation, and the determination that drives plaintiffs in these cases. We also know litigation is stressful, expensive, and disruptive. That’s why we aim for efficiency, cost-effectiveness, and empathy at every stage.
