The evidence packet: what to collect before you file a marketplace takedown

Most takedown rejections are not judgment calls. They are paperwork problems: the reviewer could not tell from your filing what was infringing, what right you hold, or how the two connect. A complete evidence packet, assembled before you file, is the difference between a takedown processed in days and one bounced back for a second round.

Start with the listing itself

Capture the full listing page as it exists right now: the product title, the seller name and storefront, the price, the item number or ASIN, and the URL. Screenshot the whole page, not just the photo, because the title text is often where the infringement lives. Save the page as a PDF too; screenshots can be questioned, and a PDF with a visible URL and date is harder to dismiss.

Do this first, before you do anything else, because listings change. Sellers edit titles after the first complaint, swap photos, or delete the listing and relist under a new ID. Evidence collected after the change is evidence of nothing. Timestamp everything: filename the files with the date, and keep the originals unedited.

Prove the product is fake

A side-by-side comparison is the core of the packet. Photograph your authentic product next to the suspect one under the same lighting: packaging, labels, stitching, logos, serial numbers. Annotate the differences directly on the images with arrows and short labels. Reviewers process dozens of filings a day; annotated images get understood in seconds, paragraphs get skimmed.

If you have not bought the suspect product, the listing photos themselves can still work when the tells are visual: stolen official photos used by an unauthorized seller, logos rendered wrong, packaging that does not match any genuine SKU. Note exactly which tell appears in which image. Vague claims like "the quality looks off" do not survive review. Specific, visible, labeled differences do.

Prove the right is yours

This is the piece most filings fumble. Include your trademark registration number and a screenshot or PDF of the registration record showing the mark, the owner name, and the goods covered. If you are filing as an agent or licensee, include the authorization letter. A filing that proves infringement but never proves ownership gets rejected on standing, no matter how obvious the fake is.

Match the mark to the listing explicitly. "Our registered mark ACME, registration 1234567, covers apparel; the listing uses ACME in the title for a jacket" is a complete chain. Do not assume the reviewer will connect the dots. They will not; that is your job.

Document the seller pattern

One listing is an incident. Five listings from the same seller is a pattern, and patterns get faster action. Include the seller's other listings of your brand, their storefront URL, and any history: previous takedowns against the same seller, previous relistings under new IDs. Marketplaces escalate repeat offenders, but only if you show them the repeat.

What goes in the packet, in order

One PDF per listing, assembled the same way every time: cover page with listing URL, seller, and date; listing screenshots; comparison photos with annotations; trademark registration record; authorization letter if applicable; seller history. Consistent packets train reviewers to trust your filings, and trusted filers get the benefit of the doubt on close calls.

File it and track it

Submit through the marketplace's brand portal rather than the generic report form whenever you have access; portal filings are routed to IP teams instead of general moderation. Log the filing date, the case or ticket number, and the outcome. When the same seller relists, your log turns a new filing into a one-paragraph escalation instead of a from-scratch case. The packet is the work. Filing it is just delivery.
