Proofbox supports inventors and companies in building a sustainable innovation strategy through efficient use of resources.
With IP-related services, Proofbox helps to optimize your budget in a targeted way. In doing so we follow international requirements as well as the GDPR and relevant ISO standards, ensuring complete data sovereignty at all times.
Proofbox is a platform for defensive publications and Proof of Existence (PoE). With a defensive publication, you can create verifiable prior art and counteract a later patent application by a third party. With our PoE service, you can verify trade secrets and prior internal use.

Defensive Publishing
Expand your innovation space through provable publication of inventions, trade fair appearances, brand use, innovations, etc.
- Immediately establish prior art and counteract later exclusivity for third parties
- Globally findable internet disclosure while containing the spread of information through discreet publication

- Document your booth and what you show
- Prepare your disclosure
- Discreetly establish prior art

This sets us apart from other providers
Robustly documented prior art, discreetly published
- Discreet disclosure: automated competitor monitoring ist not possible for the full content of any disclosure
- Discoverability of every publication through SEO according to the criteria of EPO decisions G 1/92 and T 952/92 as well as US practice on public accessibility (MPEP § 2128)
- Qualified electronic seal with timestamp: eIDAS-compliant with long-term validation (LTV) — documents integrity and publication date, the very aspects the EPO and USPTO rely on for an internet publication
- Minimal attention through paywall-restricted access to individual publications; under EPO practice (OJ 2009, 456–462) an access fee does not preclude public availability
- Logged findability for every defensive publication, auditable via a hash chain — as evidence of continuous public availability
- Persistent DOI via the Crossref infrastructure (ISO 26324) — the same identifier used by academic journals worldwide
Publish any eligible content
Anything you want to preserve from being patented or claimed by third parties
- Descriptions of inventions, processes, business models, or memos on innovations and ideas
- Source code, flowcharts, commit history, system architecture documentation, screenshots, notes
- Documentation of a trade show appearance, or documentation of prior internal use
- Plans, drawings, designs and technical drawings, sketches, and illustrations
- Cascaded publications for a broader disclosure
- Immoral or offensive content, or any information that infringes the rights of third parties
