General education, never accusations
We never state or imply that any specific real brand, seller, product listing, or marketplace is selling counterfeit goods. Everything here describes general authenticity red flags, general brand protection strategy, and general reporting channels — U.S. Customs and Border Protection, Amazon Brand Registry, and the FTC.

Brand Protection for Businesses
Counterfeiters copying your product listings, packaging, or brand name cost real revenue and damage customer trust. Here's a general overview of how businesses fight back — especially on marketplaces like Amazon.
Register your trademark
Trademark registration with the USPTO is the foundation — most enforcement tools require it. Learn more →
Record it with U.S. Customs
CBP's IPR recordation program lets border agents proactively watch for infringing shipments. Learn more →
Enroll in marketplace enforcement
Programs like Amazon Brand Registry give brand owners tools to report and remove unauthorized listings. Learn more →
Monitor proactively
Brand monitoring platforms scan marketplaces, domains, and social media continuously, not just after a complaint. See partners →
Reporting Channel: CBP vs Marketplace vs FTC
| U.S. Customs (CBP) | Marketplace (e.g. Brand Registry) | FTC | |
|---|---|---|---|
| What it handles | Goods crossing the U.S. border | Listings on that specific platform | Broader consumer protection complaints |
| Who can report | Anyone (general tips) or the trademark owner (recordation) | Generally the verified brand owner | Any consumer or business |
| Best for | Import-stage enforcement, border seizures | Removing unauthorized listings on that platform | Broader deceptive-practice complaints |
| Outcome updates | Generally no case-by-case follow-up | Platform-dependent | Generally no case-by-case follow-up |
A simplified, general overview — the right channel(s) depend on your specific situation. Speak with a licensed IP attorney for a full strategy.
