Data Syndication & Prior Art Integration

Providing automated access to defensive publications for patent offices and researchers.

Mission & Legal Validity

Prior Art is established by publishing a document via Proofbox. To guarantee global visibility and accessibility for patent examiners, we provide standardized machine-readable data streams.

Feed Access

Technical Specifications

Main Innovation Feed (Atom 1.0)

Contains all recent publications with full metadata, classification and tags.

https://www.proofbox.co/feeds/latest.xml

Targeted Delta Updates

Use this parameter to fetch only new records published after a specific date.

https://www.proofbox.co/feeds/latest.xml?since=[YYYY-MM-DD]

Metadata Standards

Timestamps

All entries are SHA-256 hashed and UTC-timestamped.

Classification

We utilize IPC (International Patent Classification) standards within our category tags.

Permanence

Every link in the feed is a permanent link to the original post of a disclosure.

Instructions for Examiners

If you are a patent examiner or represent a national IP office (e.g., USPTO, EPO, JPO), you can integrate our Atom feed directly into your automated search crawlers. For bulk access or specific API requirements, please contact our support team.
