What to Do When Someone Steals Your Intellectual Property

TL;DR: When intellectual property theft occurs, act fast. Secure your evidence, document the infringement, and consult an IP attorney. From there, you can send a cease-and-desist letter, file a takedown request, or escalate to a federal lawsuit depending on the severity of the case.

Discovering that someone has stolen your intellectual property is frustrating — and costly. Whether a competitor has copied your logo, a content farm has republished your writing, or a manufacturer is counterfeiting your patented product, the damage compounds every day you wait.

The good news? You have options. The IP infringement attorneys at Emerson Thomson Bennett walk you through the key steps to take when someone steals your intellectual property, from gathering evidence to escalating through official legal channels.

Immediate Steps When Your Intellectual Property Is Stolen

How Do You Secure Evidence of IP Ownership?

Before reaching out to the infringing party, build a solid foundation for your claim. Courts and platforms both require proof of ownership, so gather everything that establishes you as the original creator:

• Patent grants, copyright certificates, or trademark registration documents
• Design notes, draft files, or timestamped creative assets
• Screenshots of websites or social media pages showing the unauthorized use
• Archived links and copies of source code from the offending material

Act quickly. Infringing content can be deleted or altered once the other party becomes aware of your claim. Save everything before making contact.

What Counts as Documenting Intellectual Property Theft?

Documentation goes beyond proving you created something — it also means recording how your IP is being misused. Note the date you first discovered the infringement, where it appeared, how it’s being used (commercially or otherwise), and whether the infringing party is profiting from it. This information directly shapes your legal strategy.

Strategic Actions Against Infringement

When Should You Send a Cease-and-Desist Letter?

A cease-and-desist letter is often the first formal step and can resolve disputes without litigation. Have an attorney draft this letter to ensure it: 

• Demands that the infringing party stop all unauthorized use
• Outlines the legal basis for your claim
• Specifies a deadline for compliance

Many infringers — especially smaller actors — will back down when confronted with a formal legal document. For others, the letter creates a paper trail that strengthens any future lawsuit.

How Do You File a Takedown Request for Online IP Theft?

If your intellectual property is being used online, most major platforms have built-in reporting tools. Options include:

• DMCA takedown requests filed directly with hosting providers for copyright violations
• Amazon Brand Registry for trademark or product listing abuse
• Platform-specific reporting systems on social media sites like Instagram, YouTube, and Facebook

Takedown requests can remove infringing content within days, making this one of the fastest tools available to victims of intellectual property theft.

Escalation and Official Reporting

What Are the Legal Options if a Cease-and-Desist Doesn’t Work?

When informal steps fail, escalation becomes necessary. For severe or commercially profitable instances of infringement, a federal lawsuit may be the most effective path. Through litigation, you can seek:

• Injunctive relief — a court order requiring the infringer to stop
• Monetary damages — including lost profits and, in some cases, attorney’s fees

Federal IP cases are complex. Working with an experienced IP attorney significantly improves your chances of a favorable outcome.

Where Do You Report Serious Intellectual Property Theft to Authorities?

In cases involving large-scale counterfeiting or international piracy, government agencies can step in. Two key reporting channels are:

• The Internet Crime Complaint Center (IC3) — for online-based IP crimes
• The National Intellectual Property Rights Coordination Center (NIPRCC) — for referrals involving organized IP theft or cross-border infringement

Frequently Asked Questions

What should I do first if my intellectual property is stolen?

Secure and document all evidence of ownership and infringement before contacting the other party. This includes registration certificates, draft files, screenshots, and archived links.

Can I stop IP theft without going to court?

Yes. A cease-and-desist letter or platform takedown request often resolves disputes without litigation, particularly when the infringing party is a smaller actor.

When does intellectual property theft become a federal matter?

Cases involving large-scale counterfeiting, significant financial harm, or international piracy may warrant federal action, either through a civil lawsuit or a referral to agencies like the NIPRCC.

How long does it take to resolve an IP theft case?

Timelines vary. A takedown request can resolve online infringement in days, while federal litigation can take months or years depending on the complexity of the case.
