Dealt with this exact situation last year. A seller copied my entire listing -- photos, bullet points, A+ Content. Here is what worked step by step:
First, Amazon Brand Registry. If you have a registered trademark (even pending under the USPTO IP Accelerator program), you unlock powerful tools:
- Report a Violation tool -- flag counterfeit listings directly to Amazon enforcement
- Project Zero -- automated removal of infringing listings
- Transparency program -- unique per-unit codes verifying authenticity
Second, I filed a DMCA takedown for the copied photos and text. Under 17 U.S.C. Section 512, Amazon must respond to valid notices. Be specific with URLs and content. My infringing listing was removed within 48 hours of the DMCA notice.
Third, I sent a cease-and-desist letter through Amazon messaging AND to the seller registered business address. About 70% of copycats back off when served a formal legal notice because they run low-margin operations and cannot afford litigation.
For the Lanham Act claim, likelihood of confusion is nearly automatic when someone copies your exact listing. The real question is whether the seller has attachable assets. If they are a foreign entity with no US presence, enforcement is nearly impossible without involving CBP e-Recordation. Focus on Amazon internal processes first -- faster and cheaper than court.
