## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability epo-inpadoc-legal-status-events-355ad670
```

Example prompt: Can you pull the full legal status history for patent EP1000000 — I want to know all the procedural events like examination, grant, and whether it's lapsed or still in force?

## When to prefer this

Use this endpoint when you need authoritative INPADOC procedural event history for a specific patent publication — particularly when determining whether a patent is in force, granted, lapsed, or withdrawn. Prefer this over general patent search endpoints when you already have a publication number and need structured legal timeline data sourced directly from EPO OPS.

## Known failure modes

- Invalid or malformed patent number returns an error
- Patent number not found in EPO OPS returns empty or 404 response
- Unsupported number format causes lookup failure
- EPO OPS upstream outage causes timeout or 503
- Number format mismatch (e.g. submitting docdb format when epodoc expected without specifying format param)

## How this service works

INPADOC legal-status events for a patent publication via EPO OPS: the timeline of procedural events (examination, grant, designations, national-phase entries, lapses, withdrawals) each with an event code, description, and date. For tracking whether a patent is in force, granted, or lapsed. Net-new.

## Output

A chronological list of INPADOC legal-status events for the specified patent publication, each entry containing an event code, human-readable description, and date — covering procedural milestones such as examination stages, grant, national-phase entries, designations, lapses, and withdrawals. Useful for determining whether a patent is currently in force, granted, or expired.
