Online Brand Protection Toolkit: Domains, Marketplaces, Platforms, and Search Ads

By Casey Scott McKay · 2025-01-16

Online brand abuse arrives on six surfaces at once — domains, marketplaces, hosted platforms, paid search, social handles, and the gray channel — and each surface has its own forum, its own clock, its own evidence problem, and its own price; this toolkit maps all six, then routes you to the Marksy documents that do the work on each one. It compares the UDRP, the Uniform Rapid Suspension System, and an ACPA action under 15 U.S.C. § 1125(d) on remedy, proof standard, cost, and timeline, including the in rem route when the registrant is hiding behind a privacy service in another hemisphere, and it covers the prevention that pays for itself: Trademark Clearinghouse registration, sunrise periods in new gTLDs, a rational defensive-registration budget, registrar and registry locks, and watch services scoped to catch typosquats rather than exact matches. It walks the marketplace and platform side: brand registry enrollment, why a Section 512 copyright notice often moves faster than a trademark complaint, how the Tiffany/eBay specific-knowledge rule shapes what you must put in a notice, and what the INFORM Consumers Act gives you that no takedown does. It treats keyword advertising honestly — buying a competitor's name is usually lawful, the fight is about ad copy and landing pages, and a free platform complaint form frequently beats a lawsuit. It closes with social handle recovery, the reverse-domain-name-hijacking exposure that runs the other direction, a suggested reading path, a table of controlling authority, and the Marksy forms that paper each step.

Summary. Online brand abuse arrives on six surfaces at once — domains, marketplaces, hosted platforms, paid search, social handles, and the gray channel — and each has its own forum, clock, evidence problem, and price. This toolkit maps all six and then routes you to the Marksy documents that do the work on each. It compares the UDRP, the URS, and an ACPA action on remedy, proof standard, cost, and timeline, including the in rem route when the registrant is hiding overseas behind a privacy service. It covers the prevention that pays for itself: Trademark Clearinghouse registration, new gTLD sunrise periods, a rational defensive-registration budget, registrar and registry locks, and watch services scoped for typosquats. It walks marketplace registries, why a copyright notice often moves faster than a trademark complaint, how the specific-knowledge rule shapes what a notice must say, and what the INFORM Consumers Act gives you that no takedown does. It treats keyword advertising honestly, closes with social handle recovery and the reverse-hijacking exposure that runs the other way, and ends with a reading path, an authorities table, and the forms that paper each step.

Start Here

On a Monday in March, Sablefish Goods, Inc. — a Seattle maker of waxed-canvas bags selling under SABLEFISH, U.S. Reg. No. 6,412,880 in Class 18 — got six pieces of bad news in one morning. A parked page at sablefishgoods.co was serving pay-per-click links to competitors. A storefront at sablefish-outlet.shop was selling obvious fakes, its registrant masked by a privacy service and its payment processor in Shenzhen. Forty-one Amazon listings from three sellers used Sablefish product photography. The @sablefishgoods Instagram handle had been sitting dormant since 2016 in the hands of a stranger. A competitor was running a Google ad reading "Sablefish Alternatives — 40% Off" against the brand's own name. And Sablefish's authorized distributor in Rotterdam was quietly moving EU-spec inventory onto eBay in the United States.

Six problems, six different forums, six different clocks. Not one of them is solved by the instrument that solves any of the others.

This toolkit is for the person who has to triage that morning: in-house counsel with a brand-protection budget, an outside lawyer picking up an enforcement file, a founder who just discovered a typosquat, or a litigator deciding whether a Uniform Domain-Name Dispute-Resolution Policy proceeding is enough or a federal complaint is required. It answers three questions.

Which surface is this, and which forum has jurisdiction over it? A domain is not a marketplace listing, a listing is not an ad, and an ad is not a handle. Sorting the complaint into the right lane is most of the work.
What is the cheapest instrument that actually gets the outcome I need? Suspension, transfer, removal, money, or a judgment that deters the next one — these are different goals, and they map to different procedures at wildly different prices.
What do I build so this stops being an emergency? Monitoring, registry enrollment, defensive registrations, contract controls on resellers and affiliates, and an evidence protocol that survives a motion.

If you read only one thing, read UDRP vs. Federal Lawsuit: Picking the Right Weapon for Domain Disputes. It is short, and it frames the choice that governs everything downstream — speed and cost against remedy and deterrence. Almost every mistake in online enforcement is a forum-selection mistake made in the first week.

Six Surfaces, Four Remedies, One Budget

Online brand abuse looks chaotic because practitioners describe it by adversary — "the counterfeiter," "the squatter," "the competitor." It becomes tractable when you describe it by surface, because the surface determines who has the power to fix the problem.

Domains are governed by contract before they are governed by law. Every registrant of a .com, .org, .net, and most other generic top-level domains agreed, at registration, to submit to the UDRP. That consent is why you can take someone's domain away in sixty days without filing a lawsuit, and why the remedy is capped at transfer or cancellation: the panel has no power the contract did not give it. When you need money, deterrence, or reach over a registrant a panel cannot touch, you leave the contract and enter the Lanham Act through the Anticybersquatting Consumer Protection Act, 15 U.S.C. § 1125(d).

Marketplaces — Amazon, eBay, Walmart, Etsy, Alibaba, Temu — run private programs with no statutory basis at all. The Lanham Act does not require any of them to take down a listing. They do it because their terms of service say they will, and because the alternative is contributory liability under Inwood Laboratories, Inc. v. Ives Laboratories, Inc., 456 U.S. 844, 854 (1982), as narrowed for online intermediaries by Tiffany (NJ) Inc. v. eBay Inc., 600 F.3d 93, 107 (2d Cir. 2010). A takedown is a favor, not a right, and that changes how you write the notice.

Hosted platforms — the site running on Shopify, the video on YouTube, the app in an app store — sit on top of 17 U.S.C. § 512, which does impose a legal structure, but only for copyright. There is no trademark safe harbor and no trademark notice-and-takedown statute. That asymmetry is the most useful operational fact in this practice: when a fake storefront copies your product photographs and your catalog copy, the copyright notice is the instrument with teeth and the trademark complaint is the courtesy copy.

Paid search is where law and practice have diverged most. Buying a competitor's trademark as a keyword is, in most of the United States, lawful. The fight moved years ago to the ad headline, the display URL, the dynamically inserted term, and the landing page — and the most effective remedy is a free web form.

Social handles have the weakest legal architecture of all. There is no UDRP for usernames, platforms rarely release dormant handles, and much of what looks like squatting is protected speech or simply someone who got there first. Recoveries happen through impersonation policies, verified-brand programs, and money.

The gray channel is misdiagnosed most often. The goods are genuine, the seller may be an authorized distributor, and the claim is not counterfeiting. Treating it as counterfeiting will get your case narrowed and your demand letter quoted back at you.

Against those six surfaces sit four remedies, and only four:

| Remedy | What it does | Typical instrument | Realistic cost | |---|---|---|---| | Suspension | Turns the thing off; ownership unchanged | URS, platform strike, ad disapproval | $0–$500 | | Transfer / removal | Moves or deletes the asset | UDRP, marketplace takedown, § 512 notice | $0–$5,000 | | Money | Damages, profits, statutory awards, fees | ACPA suit, § 32/§ 43(a) action, counterfeiting claim | $75,000–$500,000+ | | Deterrence | A public judgment and an order that binds | TRO, preliminary injunction, consent judgment | $40,000–$250,000 |

The budget discipline follows from that table. Spend nothing on suspension and takedown until they fail. Spend real money only where a judgment changes behavior — a repeat offender, an operation with reachable assets, or conduct bad enough to support the counterfeiting remedies. Spend the recurring money on prevention, because a $150 Trademark Clearinghouse record and a well-scoped watch service cost less in a year than one UDRP.

One orientation point that saves clients from expensive theories: the Lanham Act's extraterritorial reach narrowed sharply in Abitron Austria GmbH v. Hetronic International, Inc., 600 U.S. 412, 428 (2023), which held that §§ 32 and 43(a) apply only to claims involving domestic use in commerce. Against a Guangzhou seller shipping into Seattle you still have a case; against that seller's sales into Germany you do not.

Surface One: Domains — UDRP, URS, or the ACPA

Three instruments, and the choice is almost mechanical once you know what you want.

| | URS | UDRP | ACPA (15 U.S.C. § 1125(d)) | |---|---|---|---| | Where it applies | New gTLDs and opted-in registries | All gTLDs; many ccTLDs by adoption | Any domain reachable by U.S. jurisdiction | | Mark required | Registered, court-validated, or treaty-protected, and in current use | Registered or common-law rights | Distinctive or famous at time of registration | | Standard of proof | Clear and convincing evidence | Preponderance | Preponderance | | Remedy | Suspension for the balance of the term | Transfer or cancellation | Transfer, injunction, actual damages and profits, or statutory damages of $1,000–$100,000 per domain under § 1117(d), plus fees in exceptional cases | | Response window | 14 days | 20 days (plus a short extension on request) | Rule 12 clock | | Time to outcome | 2–4 weeks | ~60 days | 12–24 months | | Filing fee | ~$375 for a small filing | ~$1,300–$1,500 single-member panel | $405 civil filing fee, and everything after it |

The UDRP requires proof of all three of: confusing similarity between the domain and the mark; no rights or legitimate interests in the registrant; and registration and use in bad faith. That conjunctive bad-faith element is the trap, and panels have softened it through the passive-holding doctrine of Telstra Corp. v. Nuclear Marshmallows, WIPO Case No. D2000-0003 (Feb. 18, 2000): a parked page with no content is still bad-faith "use" where the mark is well known, the registrant offers no credible good-faith plan, and the registration data is false or concealed. The ACPA has no such problem — § 1125(d)(1)(A) reaches anyone who "registers, traffics in, or uses" a domain with bad-faith intent to profit, in the disjunctive.

Two ACPA features do work no panel can. In rem jurisdiction under § 1125(d)(2) lets you sue the domain itself in the district where the registrar or registry sits when personal jurisdiction over the registrant is unavailable or the registrant cannot be found after due diligence — the answer to the privacy-shielded Shenzhen storefront. The Fourth Circuit read that provision to reach infringement and dilution claims, not only cybersquatting counts, in Harrods Ltd. v. Sixty Internet Domain Names, 302 F.3d 214, 228–32 (4th Cir. 2002); the price is that in rem relief is limited to forfeiture, cancellation, or transfer. And statutory damages under § 1117(d) let you recover without proving a dollar of harm, which is how the Third Circuit affirmed $10,000 per domain across five typosquatted variants in Shields v. Zuccarini, 254 F.3d 476, 486–87 (3d Cir. 2001).

Trap. The ACPA asks whether the mark was distinctive at the time the domain was registered. Under GoPets Ltd. v. Hise, 657 F.3d 1024, 1031–32 (9th Cir. 2011), a registrant who merely renews has not "registered" again, so a mark that became distinctive later cannot reach back. Transfer to a new registrant is a fresh registration, Schmidheiny v. Weber, 319 F.3d 581, 583 (3d Cir. 2003), and the Eleventh Circuit read "registers" more broadly still in Jysk Bed'N Linen v. Dutta-Roy, 810 F.3d 767, 777 (11th Cir. 2015). Pull the full WHOIS history before you plead priority.

What the Marksy corpus gives you here. Cybersquatting and the ACPA is the two-minute orientation to the federal claim — the statutory elements, bad faith, and what a court can order. Read it first if you have never worked an ACPA matter, and read it again before you write the demand letter so you do not overstate the remedy. UDRP vs. Federal Lawsuit: Picking the Right Weapon for Domain Disputes is the decision document: it prices the two routes against each other and gives you the rule of thumb — if you only want the domain, the UDRP wins nearly every time. UDRP vs. Lawsuit: Recovering an Infringing Domain restates the same fork in plainer terms for a client audience; send it to the founder who wants to know why you are not suing.

Once you have chosen the UDRP, the mechanics live in three documents. Filing a UDRP Complaint to Recover a Domain walks the sequence from provider selection through registrar lock, notification, and the implementation window; use it when the decision is made and you need to move. UDRP Complaint Checklist is the pre-filing evidence sweep — registration certificates, WHOIS captures, screenshots, correspondence — and it is the document to work the day before you draft, not the day after. UDRP Complaint — Template gives you the skeleton and the three-element structure so nothing gets left out of the pleading itself.

If you are on the other side, Responding to a UDRP Complaint is the one to reach for inside the twenty-day window. It matters more than most respondents realize: a legitimate registrant with a Oki Data Americas, Inc. v. ASD, Inc., WIPO Case No. D2001-0903 (Nov. 6, 2001), reseller defense, a personal-name defense, or a genuine descriptive use frequently wins outright — and can convert the proceeding into a finding of reverse domain name hijacking under Rules ¶ 15(e).

Prevention: Clearinghouse, Sunrise, Defensive Registration, and Watch

The Trademark Clearinghouse is the cheapest structural protection in domain practice. Deposit a nationally or regionally registered word mark, a signed declaration of use, and a specimen, pay roughly $150 per mark per year, and you get two things: the right to register that exact string as a second-level domain during every new gTLD's sunrise period, which must run at least thirty days; and a claims notice for at least ninety days after general availability whenever anyone tries to register an exact match. The limitation is exactly what it sounds like — exact match. SABLEFISH in the Clearinghouse does nothing about sablefishh.shop or sable-fish.store. That gap is what a watch service is for, which is why the two tools are complements rather than alternatives.

Defensive registration deserves more skepticism than it gets. With well over a thousand gTLDs live and another ICANN application round coming, blanket defensive registration is a budget line with no end. The rational scope is narrow: your exact mark in .com plus the two or three TLDs your customers actually type; the highest-traffic typo variants (transposition, doubled letter, dropped letter, adjacent key); the -outlet, -official, and -store constructions counterfeiters favor in your category; and the ccTLDs of markets where you actually sell. Everything else is better handled reactively, because a URS costs less than five years of defensive renewals.

Operational hygiene is the part nobody budgets and everybody regrets. Put registry lock on the two or three domains that would take the business offline, enable two-factor authentication on the registrar account, and get that account out of a departing employee's personal email. Calendar renewals in the same docket that carries your Section 8 and Section 9 deadlines — a lapsed domain is recovered at auction, not by motion.

Trademark Watch Services: What to Monitor is the Marksy starting point for the monitoring program, and the thing to remember when you scope it is that a watch tuned only to USPTO filings will miss every problem in this toolkit. Ask the vendor for domain and new-gTLD coverage, marketplace listing coverage, image matching, and social handle sweeps, and ask what the false-positive rate looks like before you sign. Docketing Deadlines: Never Miss a Renewal is short and worth re-reading here, because domain and Clearinghouse renewals belong on the same calendar as registration maintenance; brands lose more ground to expired records than to squatters. Annual Trademark Portfolio Review Checklist is the once-a-year sweep where the defensive-registration list gets pruned and the enforcement log gets reconciled against the portfolio. Building and Managing a Trademark Portfolio is the wider frame — it is where you confirm that the registrations you are about to assert online actually cover the goods being sold, which is the failure that quietly disables marketplace enrollment.

Surface Two: Marketplaces

Marketplace enforcement is a registry problem before it is a legal problem. Amazon Brand Registry, eBay's Verified Rights Owner program, Walmart's Brand Portal, Etsy's reporting flow, and Alibaba's IP Protection Platform all gate the fast lane behind enrollment, and enrollment is gated behind a registration that actually matches the goods. Enroll before you have a problem; doing it during a crisis costs you the two weeks you do not have.

Three things matter beyond enrollment.

Serialization changes the argument. Unit-level codes applied at manufacture — Amazon's Transparency program is the best-known implementation — convert a contested authenticity dispute into a scan. A listing whose units cannot produce a valid code comes down on the merits rather than on your say-so.

Copyright moves faster than trademark. A counterfeit storefront almost always copies your product photography and catalog copy. A 17 U.S.C. § 512(c)(3) notice on those images invokes a statutory scheme with a designated agent and an expeditious-removal obligation; a trademark complaint invokes a private policy. Send both, and expect the copyright notice to land first.

Notice quality decides contributory exposure. Tiffany held that generalized knowledge of counterfeiting on a platform is not enough — the platform must know of specific infringing listings. The Ninth Circuit reaffirmed that requirement for a print-on-demand marketplace in Y.Y.G.M. SA v. Redbubble, Inc., 75 F.4th 995, 1000–01 (9th Cir. 2023); the Second Circuit went the other way on facts showing deliberate avoidance in Omega SA v. 375 Canal, LLC, 984 F.3d 244, 254–56 (2d Cir. 2021), building on the flea-market willful-blindness rule of Hard Rock Cafe Licensing Corp. v. Concession Services, Inc., 955 F.2d 1143, 1149 (7th Cir. 1992). Every notice you send is a brick in a contributory case you may never file, so write each one as if it will be Exhibit 12.

Do not overlook the statute that gives you a name to sue. The INFORM Consumers Act, 15 U.S.C. § 45f, requires marketplaces to collect and verify bank, tax, and contact information from high-volume third-party sellers — generally 200 or more discrete sales and at least $5,000 in gross revenue over a twelve-month period — and to publish seller identity and address on the listing page above a higher revenue threshold. There is no private right of action, but the disclosure is the difference between a John Doe complaint and a named defendant.

Trademark Counterfeiting: Civil Seizures, Statutory Damages, and Criminal Exposure is the doctrinal anchor for this section and the next: it separates ordinary infringement from the narrower "counterfeit mark" definitions in 15 U.S.C. §§ 1127 and 1116(d)(1)(B), explains the ex parte seizure regime and the § 1117(c) statutory election of up to $2,000,000 per mark per type of goods, and traces contributory liability from Inwood through Tiffany, Omega, and Redbubble. Read it before you characterize a seller as a counterfeiter in writing, because the label carries treble damages and criminal referral on one side and a defamation risk on the other. Stopping Counterfeits at the Border: A Practitioner's Guide to CBP Recordation, Seizures, and Enforcement Programs is the operational companion; its Stage 9 covers marketplace registries directly and Stage 10 covers the John Doe and Schedule A package, but its real value online is upstream — recording with Customs under 19 C.F.R. Part 133 at $190 per class intercepts inventory before it ever reaches a listing. Anticounterfeiting Program Checklist: Recordation, Marketplace Takedowns, and Seizure Response is the ten-phase build sheet: registry enrollment, serialization, a test-buy protocol that produces evidence admissible under Fed. R. Evid. 901 and 902(13)–(14), and a takedown sequence that deliberately runs § 512 notices ahead of trademark complaints. Work it top to bottom once, then run it annually.

Surface Three: Platforms and the Section 512 Machinery

A hosted platform is a different animal from a marketplace: it stores material at the direction of users, which puts it inside 17 U.S.C. § 512(c) if it has registered a designated agent, adopted and reasonably implemented a repeat-infringer policy, and accommodated standard technical measures. Section 230 of the Communications Decency Act does not help the infringer here — 47 U.S.C. § 230(e)(2) expressly carves out intellectual property claims, although the Ninth Circuit read that carve-out to cover only federal IP in Perfect 10, Inc. v. CCBill LLC, 488 F.3d 1102, 1118–19 (9th Cir. 2007).

Two operational rules. First, a takedown notice is sworn: § 512(c)(3)(A)(vi) requires a statement under penalty of perjury, and Lenz v. Universal Music Corp., 815 F.3d 1145, 1153 (9th Cir. 2016), requires a subjective good-faith consideration of fair use before you send it. Document that consideration in the file, in two sentences, every time. Second, the counter-notice puts your own jurisdictional consent on the table: the material comes back in ten to fourteen business days unless you file suit, and the counter-notifying user has already consented to a forum you may not want.

The DMCA Safe Harbor: How Section 512 Shields Platforms and Binds Rights Holders is the doctrine — the four harbors, the § 512(i) threshold conditions, red-flag knowledge, the right-and-ability-to-control prong, and why most safe-harbor fights are actually repeat-infringer fights. Read it when you need to know whether the host you are dealing with is protected, and therefore whether escalation past the notice is realistic. Sending and Fighting a DMCA Takedown: A Practitioner's Guide to Notices, Counter-Notices, and Misrepresentation Claims is the fifteen-stage working manual, including the platform-specific mechanics for marketplaces, hosts, CDNs, code hosts, and app stores, and a full treatment of the consent-to-jurisdiction trap on the counter-notice side. Use it the hour a notice needs to go out or an incoming notice hits the inbox. DMCA Takedown Notice Checklist: Statutory Elements, Counter-Notice, and Repeat-Infringer Policies is the eleven-phase version for running the same work at volume without accumulating § 512(f) misrepresentation exposure.

If the platform in question is yours — you run the site the infringing user posted to — the exposure runs the other way, and the fix is architectural. The Legal Layers of a Website: IP, Contracts, Privacy, and the DMCA Before You Ship explains why the $6 designated-agent registration is the highest-return filing in technology law and what the repeat-infringer condition actually demands. Launching a Website or App Without Legal Debt: A Practitioner's Guide to the Pre-Ship Legal Stack sequences that work on a T-minus calendar, including the domain and handle sweep at T-165 that would have prevented half of Sablefish's Monday. Website and App Launch Legal Checklist: IP, Terms, Privacy, and Compliance is the roughly 110-action version with the post-launch monitoring phase that turns launch hygiene into an ongoing brand-protection program.

Surface Four: Search Ads, SEO, and the Free Form That Beats a Lawsuit

Here is the honest state of the law. Selling and buying trademarks as keywords is a "use in commerce" — Rescuecom Corp. v. Google Inc., 562 F.3d 123, 127–31 (2d Cir. 2009) — which sounds like a plaintiff's victory and was in fact the end of the plaintiffs' best argument, because it moved the case onto likelihood of confusion, where labeled ads usually win. Initial interest confusion, born of the billboard metaphor in Brookfield Communications, Inc. v. West Coast Entertainment Corp., 174 F.3d 1036, 1062–64 (9th Cir. 1999), was substantially dismantled by Network Automation, Inc. v. Advanced Systems Concepts, Inc., 638 F.3d 1137, 1148–54 (9th Cir. 2011), which recentered the analysis on ad labeling, consumer sophistication, and the actual appearance of the results page. Multi Time Machine, Inc. v. Amazon.com, Inc., 804 F.3d 930, 936–38 (9th Cir. 2015), then held that clear labeling defeated a search-results claim as a matter of law.

So the modern claim is not "they bid on my name." It is "their headline uses my mark," or "dynamic keyword insertion put my mark in their ad," or "the display URL implies affiliation," or "the landing page sells a competing product under my name." Those still win, and Rosetta Stone Ltd. v. Google, Inc., 676 F.3d 144, 153–60 (4th Cir. 2012), shows that even a platform can face a jury on the right record.

The practical point is that you rarely need a court. Google's trademark policy restricts trademark use in ad text and is enforced through a free complaint form; Microsoft Advertising runs its own concern form. And 15 U.S.C. § 1114(2)(B) limits the remedy against an innocent publisher of paid advertising to injunctive relief anyway — so the form frequently delivers everything the lawsuit could.

Practice tip. Before you complain about anyone else's ads, pull your own search terms report and your affiliate schedule. Half the "competitor" ads that trigger client outrage turn out to be the client's own affiliates bidding on the client's own brand, or a reseller doing exactly what the distribution agreement permits.

Buying a Competitor's Name: Keyword Advertising and the Death of Initial Interest Confusion is the full doctrinal history, circuit by circuit, including the Eighth Circuit's continued recognition of presale confusion and the antitrust limits on negative-keyword settlement clauses after 1-800 Contacts, Inc. v. FTC, 1 F.4th 102, 115–19 (2d Cir. 2021). Read it before you send a demand, because the demand you would have sent in 2009 now invites a declaratory judgment action and an antitrust counterclaim. Running a Keyword and Paid-Search Trademark Program: A Practitioner's Guide to Monitoring, Complaints, and Enforcement is the sixteen-stage operating manual: auditing your own account first, capturing ads so the exhibits survive an authentication fight, working the Google and Microsoft complaint procedures, and drafting a settlement covenant that does not build a cartel. Keyword Advertising Compliance and Enforcement Checklist compresses the same program into eleven phases with a five-question triage tree that routes every capture to exactly one remedy — which is what you want on a Monday with forty screenshots and no plan.

Surface Five: Social Handles, Impersonation, and Who Owns the Account

There is no UDRP for @sablefishgoods. Recovery runs through three channels, in this order of realism.

Platform policy. Every major platform prohibits impersonation and most prohibit trademark-infringing usernames, but the bar is high: a dormant account holding your brand as a handle, without more, is usually neither impersonation nor infringement, because there is no use in commerce. What moves platforms is an account posing as the brand — logo, product images, "official" language, a link to a lookalike storefront. Build the complaint around confusion evidence, not around the string.

Money. Buying the handle is frequently the cheapest outcome and is not a concession. Paper it: an assignment of whatever rights exist, a representation of non-infringement, a covenant not to re-register variants, and payment released only on completed transfer.

Litigation, in the narrow cases where it works. Where the handle uses a real person's name, 15 U.S.C. § 8131 supplies a cause of action against registering a living person's name with intent to profit by resale — though it reaches domains rather than handles, and offers injunctive relief and fees rather than statutory damages. Where the account was created by an employee, contractor, or collaborator and then walked out the door, the fight is about ownership, not infringement, and courts do treat accounts as company property: JLM Couture, Inc. v. Gutman, 24 F.4th 785, 796–802 (2d Cir. 2022) (preliminary injunction over control of a designer's Instagram account); In re CTLI, LLC, 528 B.R. 359, 366–74 (Bankr. S.D. Tex. 2015) (accounts are property of the bankruptcy estate). The prevention is contractual: name the accounts as company property in every employment, contractor, agency, and influencer agreement, and hold the credentials centrally.

Your Face Is Not Public Domain: The Right of Publicity, NIL, and the State-Law Patchwork maps the state-by-state right that does the work when the misuse is of a person rather than a mark; reach for it when the fake account impersonates your founder rather than your company. Clearing and Licensing Name, Image, and Likeness: A Practitioner's Guide for Brands, Creators, and Athletes is the transactional side — open it before an influencer campaign creates the account-ownership problem — and Name, Image, and Likeness Clearance Checklist: Releases, Licenses, and Post-Mortem Rights is the clearance run for campaigns featuring real people.

Surface Six: Real Goods, Wrong Channel

The Rotterdam distributor is not a counterfeiter. The goods are genuine; the problem is the channel. Under the first sale doctrine, reselling genuine goods is lawful — unless the goods are materially different from those the U.S. trademark owner authorized, in which case they are infringing even though they are real. Different voltage, different formulation, different warranty, missing quality-control codes, different regulatory labeling: each has supported liability. The customs mechanism runs through 19 C.F.R. § 133.23 and the Lever rule, and the private-law mechanism runs through distribution agreements with territorial and channel restrictions that are actually enforced.

Gray Market Goods: The First Sale Doctrine, Material Differences, and Parallel Imports is the doctrine, and it is the document that stops a client from sending a counterfeiting demand to an authorized distributor. Fighting or Defending Parallel Imports: A Practitioner's Guide to Material Differences, Customs, and Distribution Control is the execution: proving material difference, filing the customs restriction, and rewriting the distribution paper so the leak closes at the source. Gray Market Enforcement Checklist: Proving Material Differences and Controlling Distribution is what you work when the marketplace listings are genuine and the takedown was rejected.

Two related failures worth naming. If your resellers use your mark without any real quality control, you have a naked licensing problem, not just a channel problem — Naked Licensing: How Sloppy Quality Control Kills a Trademark explains how that becomes abandonment. And if your brand style is drifting across thousands of third-party listings and hashtags, Preventing Genericide: A Brand Owner's Guide to Trademark Style, Policing, and Primary Significance Evidence is the policing discipline that keeps the mark from becoming the category name.

The Other Chair: When the Use Is Lawful

Roughly a third of the "infringements" on a monitoring report are lawful, and sending demands into that third is how brand owners acquire declaratory judgment defendants, antitrust counterclaims, and reverse-domain-name-hijacking findings that follow them into the next proceeding. A UDRP panel that finds RDNH under Rules ¶ 15(e) publishes it; the ACPA supplies a companion cause of action for a registrant whose domain was wrongly suspended or transferred, 15 U.S.C. § 1114(2)(D)(v).

The lawful third breaks into recognizable categories. Referential use by resellers and repair shops, protected under the nominative fair use line running through Toyota Motor Sales, U.S.A., Inc. v. Tabari, 610 F.3d 1171, 1175–79 (9th Cir. 2010) — which specifically addressed domain names such as buy-a-lexus.com. Descriptive use of a word that happens to be your mark, protected by 15 U.S.C. § 1115(b)(4). Criticism and commentary, protected as far as Lamparello v. Falwell, 420 F.3d 309, 318–22 (4th Cir. 2005), and Taubman Co. v. Webfeats, 319 F.3d 770, 778 (6th Cir. 2003), extend — though Coca-Cola Co. v. Purdy, 382 F.3d 774, 786 (8th Cir. 2004), and People for the Ethical Treatment of Animals v. Doughney, 263 F.3d 359, 366–69 (4th Cir. 2001), mark where the protection stops. And expressive use, after Jack Daniel's Properties, Inc. v. VIP Products LLC, 599 U.S. 140, 153–61 (2023), which held that Rogers does not apply when the mark is used as a source identifier.

Descriptive and Nominative Fair Use: When You Can Legally Use Someone Else's Trademark separates the statutory defense from the judge-made one, maps the three-way circuit split on nominative use, and has a section directly on keyword ads and domain names. Read it before you draft any demand aimed at a reseller, a repair shop, or a compatibility claim. Raising a Trademark Fair Use Defense: A Practitioner's Guide to Classic Fair Use, Nominative Use, and Comparative Advertising is the defense-side execution manual, twelve stages from the demand letter to the verdict form; enforcement counsel should read Stage 4 in particular, because it is a preview of the answer you will receive. Trademark Fair Use Audit Checklist: Clearing Third-Party Marks in Advertising and Content runs the same analysis prophylactically across a campaign, including a channel-clearance phase covering paid search, marketplace titles, subdomains, hashtags, and alt text. Rogers, Jack Daniel's, and the Trademark Parody Problem is the one to read when the offending account is a parody, and Expressive Use and Parody Risk Checklist: Clearing Creative Uses of Third-Party Marks is the clearance version. Responding to a Cease-and-Desist Letter belongs in this section too — it is the fastest way to understand what your own demand looks like from the other side.

Escalation: Demands, Injunctions, and Money

When suspension and takedown fail, the ladder is short. A demand letter comes first — Sending an Effective Cease-and-Desist Letter explains why the tone and the ask matter more than the citations, and why an aggressive letter to a sympathetic recipient is a screenshot waiting to happen. Pre-Litigation Enforcement Checklist is the file you build before the letter goes out: chain of title confirmed, registrations current, evidence captured and dated, and a decision recorded about what outcome you will actually accept.

Then the forum question. Federal Court vs. TTAB: Where to Bring Your Dispute is the reminder that the Board cannot enjoin anything or award a dollar — which makes it the wrong forum for every problem in this toolkit except a parallel registration fight. Trademark Infringement: Proving Likelihood of Confusion is the element you will be proving in any of these actions and the frame for the evidence you should already be collecting.

For emergency relief, Moving for a TRO or Preliminary Injunction in a Trademark Case: A Practitioner's Guide covers the four-factor showing, the rebuttable presumption of irreparable harm restored by the Trademark Modernization Act in 15 U.S.C. § 1116(a), the Rule 65(c) bond, and — critically for online defendants — ex parte practice and alternative service under Fed. R. Civ. P. 4(f)(3). Preliminary Injunction Motion Checklist for Trademark Cases: Declarations, Bond, and Notice is the assembly list for the papers. On money, What a Trademark Win Is Worth: Injunctions, Profits, Damages, and Fees Under Section 35 prices the outcome honestly after Romag Fasteners, Inc. v. Fossil, Inc., 590 U.S. 212, 218 (2020), and Trademark Monetary Recovery Checklist: Proof of Profits, Damages, Corrective Advertising, and Fees is the proof plan. If the mark is famous and the domain is dilutive rather than confusing, Trademark Dilution Under the TDRA: Blurring, Tarnishment, and the Fame Threshold and Bringing and Defending a Federal Dilution Claim: A Practitioner's Guide carry the alternative theory — the ACPA expressly reaches domains that dilute a famous mark, which matters for sucks sites and tarnishing storefronts.

Forms and Templates

UDRP Complaint — Template is the skeleton for the administrative proceeding; fill the three UDRP ¶ 4(a) elements in the order the panel reads them, and attach the WHOIS capture and screenshots as annexes rather than describing them in the body. Trademark Cease-and-Desist Letter — Template is the demand you will send far more often than you file anything — strip the damages recitation before it goes to a small reseller, and pair it with Sending an Effective Cease-and-Desist Letter.

Trademark Coexistence Agreement — Template is the right instrument when the other side has a genuine claim to the string — a descriptive use, a personal name, a different market — and the sensible outcome is a bounded arrangement rather than a transfer; it also carries the negative-keyword and channel-restriction covenants that resolve most search-ad disputes, subject to the antitrust guardrails above. Trademark Assignment Agreement — Template is the closest Marksy analogue for papering a negotiated domain or handle purchase: adapt the granting clause to the asset, add a non-re-registration covenant, and hold payment against completed transfer at the registrar.

Trademark License Agreement — Template and How to Draft a Trademark License Agreement authorize the resellers and affiliates whose unauthorized ads and listings generate a surprising share of enforcement volume; a two-page authorization with quality-control and channel terms prevents more disputes than any takedown program. Trademark Portfolio Inventory — Template is where domains, handles, and Clearinghouse records belong alongside the registrations, so the annual review actually sees them.
