Someone Is Selling Knockoffs of My Product on Amazon — What Can I Do?
A counterfeiter is undercutting your Amazon listing with fakes. Here's what California sellers can do — from platform takedowns to attorney cease and desist letters.
Short answer: File an Amazon counterfeit takedown through Brand Registry or a DMCA notice to remove the listing now. Then send an attorney-drafted cease and desist letter citing the federal Lanham Act — that's the document that converts a cheap infringement into a documented legal risk the counterfeiter has to weigh before relisting.

A Bay Area skincare founder found it in March: her vitamin C serum, copied down to the bottle shape, selling at $14.99 against her $42. Three hundred reviews, five stars. Her own listing had started collecting return requests from buyers who'd received the knockoff instead.
The counterfeit had been live for two months. She'd lost roughly $3,200 in sales before she noticed.
A counterfeiter on Amazon costs you sales, trashes your reviews with complaints about a product you didn't make, and rides your brand equity for free. You have legal tools to stop this. The platform takedown removes the listing fast. The attorney cease and desist letter is what actually discourages the seller from relisting. In most cases you need both — because one removes a listing and the other changes a calculation.
What Legal Rights Do You Actually Have?
Your strongest tools are federal. The federal Lanham Act, 15 U.S.C. §1114, prohibits unauthorized use of a registered trademark in commerce. If someone sells a knockoff under your brand name or a confusingly similar one, that's trademark infringement. Distinctive trade dress — a specific bottle shape, color scheme, or packaging configuration — is protected under §1125(a) even without registration.
If counterfeiters use your product photos, which is nearly universal, the federal DMCA, 17 U.S.C. §512, gives you a separate takedown route. Your photos are copyright-protected the moment you create them.
California adds a layer: Cal. Bus. & Prof. Code §17200 makes selling counterfeits an unfair business practice under state law — relevant if you litigate in California courts.
> Federal law (Lanham Act, 15 U.S.C. §1114) — Prohibits unauthorized use of a registered trademark in commerce. For willful counterfeiting, remedies extend to treble damages and attorney's fees under 15 U.S.C. §1117.
The Platform Takedown: Fast but Reversible
Amazon's Brand Registry lets registered trademark owners report infringing listings directly — responses typically come within 24 to 72 hours. DMCA notices cover stolen photos independently.
The problem: takedowns remove a listing, not a seller. The same counterfeiter can relist within days under a variant title. Takedowns are the first move in a sequence, not the entire strategy.
What a Cease and Desist Letter Actually Does
Right now, infringing your trademark costs the counterfeiter nothing. Amazon deletes the listing; they relist. A temporary interruption, not a consequence. An attorney cease and desist letter rewrites that ledger.
A C&D puts the counterfeiter on formal notice: a licensed attorney reviewed the claim, found it credible, and set a deadline. Ignoring it converts a platform dispute into a federal lawsuit — and crucially, converts accidental infringement into willful infringement.
Willfulness is the lever. Under the federal Lanham Act (15 U.S.C. §1117), willful counterfeiting of a registered mark opens the door to treble damages — up to three times actual losses — and attorney's fees. The C&D is the document that starts that clock.
| Tool | Speed | Removes listing? | Deters relisting? | Creates legal record? | |------|-------|------------------|-------------------|----------------------| | Amazon Brand Registry takedown | 24–72 hrs | Yes | Rarely | No | | DMCA §512 notice | 2–5 days | Yes (photos) | Rarely | Partial | | Attorney cease and desist | 7–14 days | No | Often | Yes | | All three, in sequence | — | Yes | Usually | Yes |
What to Do First
File the takedown immediately — screenshot everything with dates first. Then, within the same week, get an attorney cease and desist letter in motion. The letter should cite your Lanham Act rights, demand removal of all infringing listings, and give the infringer 10 to 14 days to respond.
The attorney signature matters. It tells the recipient that a real person reviewed the claim and found it worth pursuing — which is why the letter works where a polite email doesn't. For more on when a demand letter is the right tool, see When Do You Need a Legal Demand Letter?.
If the C&D is ignored, you have a paper trail establishing willfulness. Federal court and §1117 treble damages become live options.
The skincare founder filed her Brand Registry complaint the day she found the knockoff. Her attorney sent a C&D two weeks later. The seller relisted once, then went dark.
The counterfeiter's listing is gone. Her rating is recovering. The C&D made relisting feel expensive rather than free — that's the only outcome a takedown alone never produces.
If a flat-fee attorney letter is what stands between you and another month of this, Talk to My Lawyer handles exactly that — a California attorney reviews your infringement facts and signs the letter.
