Trademark Infringement on Social Media

An Orange County skincare company discovered that a competitor was running Instagram ads using their exact brand name as a hashtag and in the ad copy itself. The competitor’s products were cheaper knockoffs. Customers were confused. Sales dropped. The client had a federally registered trademark. They’d filed with the USPTO two years earlier. That registration gave them options that an unregistered brand would not have had.

Trademark infringement on social media is a serious IP enforcement problem. The platforms are global. The barriers to entry are zero. Anyone can set up an account using your brand name, run ads targeting your customers, and sell knockoff products before you even know it’s happening. The Lanham Act gives you federal remedies, and every major platform has an internal reporting system. But knowing which tool to use, and when platform takedowns aren’t enough, is the difference between protecting your brand and watching it erode.

I’m Evan Dotta, a partner at Mister Wolf P.C. I work with businesses and brand owners across Orange County and Southern California on trademark and intellectual property enforcement, including social media disputes. Here’s how the law works, what each platform offers, and when you need to move from takedown notices to federal court.

The Lanham Act Framework

Two sections of the Lanham Act (15 U.S.C. Section 1051 et seq.) provide the federal framework for trademark enforcement.

Section 32 (15 U.S.C. Section 1114) applies to registered trademarks. If you have a federal registration and someone uses your mark (or a confusingly similar mark) in commerce in connection with goods or services without your authorization, and in a way that causes consumer confusion, you have a claim for infringement. Remedies include injunctive relief, the infringer’s profits, your actual damages, and attorney’s fees in exceptional cases.

Section 43(a) (15 U.S.C. Section 1125(a)) protects unregistered marks. Even without a federal registration, you can bring a claim for false designation of origin or false advertising. The standard is similar: you need to show that the defendant’s use of a mark is likely to cause confusion about the source, sponsorship, or affiliation of their goods or services.

Federal registration is powerful. You get a legal presumption of ownership and validity. You get nationwide constructive notice. You get access to enhanced damages for willful infringement. You can record your registration with U.S. Customs and Border Protection to stop counterfeit imports. If you’re running a business in Orange County or anywhere in Southern California and haven’t registered your trademark with the USPTO, that should be your first step. For a full overview of brand registration, see our guide on protecting your brand in Orange County.

The USPTO reported more than 824,000 new trademark application classes filed in fiscal year 2025. That volume reflects how many businesses understand the value of registration. But many still don’t, and they find themselves in a much weaker position when infringement happens.

The Sleekcraft Test in the Ninth Circuit

In the Ninth Circuit (which covers California), courts determine likelihood of confusion using the eight-factor test from AMF Inc. v. Sleekcraft Boats (1979). The factors are:

Strength of the mark
Proximity of the goods or services
Similarity of the marks
Evidence of actual confusion
Marketing channels used
Type of goods and degree of consumer care
Defendant’s intent in selecting the mark
Likelihood of expansion of product lines

Social media infringement makes several of these factors easier to prove. Marketing channels? Both parties are using the same platform. Proximity of goods? If a competitor is using your brand name to sell competing products on Instagram, the goods are identical. Defendant’s intent? Using someone’s exact trademark as a hashtag or in ad copy is hard to explain as coincidental.

Courts in the Central District of California, which handles cases from Los Angeles and Orange County, apply the Sleekcraft factors regularly in social media trademark disputes. The analysis is fact-intensive, but the framework is well established.

How Do You Report Trademark Infringement on Each Platform?

Instagram and Facebook (Meta)

Meta’s IP reporting tool is at facebook.com/ip/reporting. You can report trademark infringement on both Instagram and Facebook through the same portal. You’ll need:

Your trademark registration details (or evidence of unregistered trademark rights)
The specific content or account you’re reporting
An explanation of how the reported content infringes your trademark

Meta reviews reports and typically responds within a few business days. If the report is valid, they remove the infringing content or disable the infringing account. Meta also offers the Brand Rights Protection tool for businesses with verified trademark registrations, it provides advanced monitoring and bulk reporting capabilities.

TikTok

TikTok’s trademark infringement reporting is at tiktok.com/legal/report/trademark. The process is similar to Meta’s. You identify the infringing content, provide your trademark details, and submit. TikTok’s review timeline can be slower, sometimes taking up to two weeks. For repeat infringers, TikTok may suspend or permanently ban the account.

X (formerly Twitter)

X’s trademark policy allows you to report accounts or content that misuse your trademark. The reporting form is accessible through X’s help center. X distinguishes between trademark infringement in content (posts, ads) and trademark infringement in usernames. For username disputes, X may release the username to the trademark owner if the account is inactive or was registered in bad faith.

General Limitations

Platform takedowns are free and fast. But they have real limitations. They only remove the specific content you report. They don’t prevent the infringer from creating a new account and starting over. They don’t compensate you for lost sales or brand damage. They don’t create legal precedent. The platform makes an internal policy decision, not a legal ruling.

Register your trademark with Meta’s Brand Rights Protection program and any other platform-specific brand protection tools available. These programs give you faster reporting, automated monitoring, and in some cases, earlier detection of infringing content before it spreads. If the same infringer is also using your mark in domain names, compare the platform process with the UDRP domain dispute process.

Can Someone Trademark a Hashtag?

Hashtags as Trademarks

Yes, hashtags can be trademarks. The USPTO registers hashtags as trademarks when they identify and distinguish the source of goods or services. The hashtag symbol (#) is treated as punctuation and doesn’t affect registrability.

The problem arises when a competitor uses your trademarked hashtag to divert traffic to their own products. A beauty brand in Irvine registered #[BrandName] as a federal trademark and found that a Chinese manufacturer was using the same hashtag on Instagram and TikTok to sell counterfeit versions. Every post with the hashtag directed customers to the knockoffs.

We sent a cease-and-desist to the manufacturer and filed takedown reports on both platforms. The posts came down within a week. But the manufacturer created new accounts and started again. That’s when we filed a Lanham Act complaint in the Central District. The federal court case produced a permanent injunction that applied across all platforms, not just the ones where we’d filed takedown reports.

Monitoring Hashtag Misuse

Hashtag monitoring is an ongoing obligation. Trademark owners must police their marks, or they weaken over time. Set up alerts for your brand’s hashtags and variations. Check competitor campaigns for use of your marks. Document every instance of infringement, even if you don’t immediately take action. That documentation proves a pattern if you later need to show willfulness.

UDRP vs. Lanham Act

Social media handle squatting (someone registers your brand name as a username) is similar to domain name squatting, but the legal tools are different. The UDRP (Uniform Domain-Name Dispute-Resolution Policy) applies to domain names, not social media handles. For handles, you typically rely on the platform’s internal dispute process or the Lanham Act.

Under Section 43(a) of the Lanham Act, you can sue someone who uses your trademark as a social media handle if the use in commerce is likely to cause consumer confusion about source, sponsorship, or affiliation. A dormant handle with no commercial use is harder. A handle used to solicit customers, redirect traffic, impersonate your company, or support a competing campaign is a much stronger case.

Some platforms have specific username dispute processes. Instagram and Facebook may remove infringing content, disable accounts, or address usernames through Meta’s IP tools. X has a separate trademark policy for account names and content. TikTok’s process is narrower and more content-focused. In all cases, having a federal trademark registration makes the process faster and your position stronger.

The ACPA Option

The Anticybersquatting Consumer Protection Act (15 U.S.C. Section 1125(d)) applies specifically to domain names, not social media handles. But if the squatter has also registered a domain name using your trademark, the ACPA gives you a federal cause of action with statutory damages of up to $100,000 per domain.

Are Influencers Liable for Trademark Misuse?

Influencer Liability

Influencers who use a brand’s trademark without authorization in sponsored content can be liable for trademark infringement. The analysis depends on whether the use creates a likelihood of confusion about sponsorship or endorsement.

If an influencer in Newport Beach posts content implying that a particular luxury brand sponsors or endorses their post, and no such relationship exists, the brand has a claim under Section 43(a). The influencer is liable, and so is any company that paid the influencer to create the content.

The FTC’s endorsement guidelines require influencers to disclose material connections with brands. But the FTC guidelines address disclosure, not trademark use. A properly disclosed paid partnership can still constitute trademark infringement if the influencer uses the brand’s trademark in a misleading way.

Orange County has a dense concentration of influencer-driven businesses. Fashion, beauty, fitness, and lifestyle brands in Irvine, Costa Mesa, Huntington Beach, and Newport Beach use influencer marketing heavily. Protecting your trademark in this space means monitoring competitors and the influencers who mention your brand, and how they do it.

Review your influencer agreements to confirm they include trademark usage guidelines. Specify how your brand name, logo, and hashtags can and cannot be used. Include a termination clause for trademark misuse. It costs nothing and prevents expensive disputes later.

When Do You Need Federal Court Instead of a Platform Takedown?

Beyond the Reporting Tools

Platform takedowns handle individual posts. Federal court handles patterns of behavior. You need to escalate beyond platform reporting when:

The infringer creates new accounts after takedowns and continues the infringement
The infringement has caused significant financial damage that platform removal won’t remedy
You need a permanent injunction that applies across all platforms, not just one
You want to recover damages (lost profits, the infringer’s profits, or statutory damages)
The infringer is operating a systematic counterfeiting or imitation operation

Filing a Lanham Act complaint in the Central District of California opens remedies that no platform offers. Under 15 U.S.C. Section 1117, you can recover the defendant’s profits, your actual damages, and court costs. In exceptional cases, the court trebles profits and awards attorney’s fees. You can also get a temporary restraining order within days of filing if the situation is urgent.

A business in Anaheim we represented had filed over 50 platform takedown reports across Instagram, TikTok, and Amazon over an eight-month period against a single counterfeiter. The content kept coming back under new accounts. We filed in the Central District, obtained a preliminary injunction, and served discovery to identify the counterfeiter’s payment processors and fulfillment centers. The injunction applied to all platforms. The counterfeiter’s PayPal and Stripe accounts were frozen. The operation shut down within six weeks of the court order.

The Three-Layer Approach

Effective social media brand protection operates on three levels, and all three need to work together.

Layer 1: Registration and documentation: Register your trademark with the USPTO. Record your registration with each platform’s brand protection program. Document your brand guidelines (approved uses, logo specs, authorized hashtags).

Layer 2: Monitoring and detection: Use monitoring tools (Brandwatch, Mention, Google Alerts) to track brand mentions across social platforms. Conduct manual searches monthly. Check the USPTO’s Trademark Search system for new applications that conflict with your mark, and calendar maintenance deadlines so the registration you rely on does not lapse. Our guide to trademark renewal and maintenance deadlines covers those filing windows.

Layer 3: Enforcement: Develop a graduated response. Use platform takedowns for isolated incidents, cease-and-desist letters for repeat offenders, and federal litigation for systematic infringers. Document every action.

At Mister Wolf P.C., our Orange County intellectual property lawyers help Orange County and Southern California businesses build and execute brand protection strategies that scale with their growth. The earlier you start monitoring, the smaller the problems stay.

If you’ve spotted someone using your trademark on social media and aren’t sure whether to file a platform report or call a lawyer, start by documenting the infringement with screenshots and timestamps. Check your federal registration status. Then bring that evidence to a trademark attorney who can assess whether platform tools are enough or whether federal enforcement is the right move for your situation.
