Product · Proof of Use

Evidence of trademark use, continuously documented.

Proof of Use continuously documents the use of a trademark across all relevant digital channels — websites, shops, marketplaces, social media — and produces a chronological, hash-sealed chain of evidence.

The Problem

Trademark use must be proven — often years later.

When a trademark is challenged, the holder must demonstrate genuine use over time. Screenshots, archive copies and scattered files rarely stand up: they document moments, not development.

Proof of Use is built to close exactly this gap — by capturing the digital footprint of a trademark continuously, before it is needed.

The Solution

Continuous documentation across every digital channel.

How it works

One shared Evidence Engine.

  1. 01

    Baseline

    Initial state of every channel is captured.

  2. 02

    Snapshots

    Continuous, scheduled capture per channel.

  3. 03

    Delta Analysis

    Structural changes are detected over time.

  4. 04

    Evidence Chain

    All events are hash-sealed into a verifiable chain.

Evidence Timeline

A chronological record — not a folder of screenshots.

Every captured event is filed onto a single, verifiable timeline. Every entry carries a timestamp, a SHA-256 hash and a link to the underlying snapshot.

Architecture

Built on the shared Evidence Engine.

Baseline · Snapshots · Delta Analysis · Evidence Chain — the same architecture that powers every EvidenceFirst product.

Evidence Report

A self-contained, legally usable document.

  • Trademark profile (name, registration, classes, owner)
  • Channel inventory with capture status
  • Chronological evidence of use per channel
  • Hash chain (SHA-256) with full custody log

Document use before it is challenged.

Proof of Use turns continuous capture into legally usable evidence.
