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.
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.
Initial state of every channel is captured.
Continuous, scheduled capture per channel.
Structural changes are detected over time.
All events are hash-sealed into a verifiable chain.
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.
Baseline · Snapshots · Delta Analysis · Evidence Chain — the same architecture that powers every EvidenceFirst product.
Proof of Use turns continuous capture into legally usable evidence.
