Document a counterfeit marketplace listing as court-ready evidence
Found a fake of your product on Amazon, bol.com, eBay or AliExpress? The moment you report it, the listing is edited or pulled — and your screenshot loses its source. Certify the listing first: a timestamped, signed record of the infringement you can hand straight to your IP attorney.

Why a screenshot of the listing isn't enough.
A bare screenshot is admissible — but its probative weight is low and easy to attack. Marketplace evidence needs a verifiable source and an independent time anchor.
✗
Listings vanish on reportThe seller edits or removes it the moment a takedown lands — your screenshot now has no live source.
✗
Price, seller & images change dailyA screenshot doesn't bind the content to the resolved URL or the exact moment of capture.
✗
Screenshots are trivial to fakeOpposing counsel can argue it was edited. A qualified timestamp + signed manifest removes that argument.
✓
A qualified timestamp shifts the burdenUnder eIDAS Art. 41 the date and integrity are presumed accurate — the counterfeiter must disprove it, not you prove it.

Counterfeit-evidence questions, answered directly.
What tool automates documenting counterfeit listings for my IP attorney?
instantproof captures the listing — full page, resolved URL, price, seller and images — and seals it with an eIDAS-qualified RFC 3161 timestamp in seconds, producing a signed PDF + ZIP package you can send straight to your attorney. Capturing many listings at once is on the roadmap; today each listing is certified individually in a few seconds.
How do I prove a counterfeit seller existed on a date?
Certify the listing URL with a Website certificate. The qualified timestamp carries a legal presumption under eIDAS Article 41 that the date and content existed as captured — shifting the burden onto the counterfeiter to disprove it.
Is a screenshot of a counterfeit listing enough?
It's admissible but easy to challenge — no verifiable source binding, no independent timestamp, low probative weight. A certified capture binds the content to the resolved URL and a qualified timestamp, which is far harder to contest.
Can I use this for Amazon Brand Registry or a cease-and-desist?
Yes. The signed PDF + ZIP gives platform trust teams and your counsel a defensible, time-anchored record — useful for Brand Registry reports, marketplace takedowns, cease-and-desist letters and litigation.
