# Google Patent Documents - Claims, Assignees & Changes — workflow

## Choose this tool

Use this tool when you already have patent publication IDs and need structured claims, abstracts, dates, assignees and classification evidence for research or competitive monitoring.

Useful output columns: `publicationId`, `title`, `assignees`, `filingDate`, `publicationDate`, `claimsReturned`, `claimsTruncated`, `comparisonStatus`, `url`.

## Practical workflow

Start with one known publication ID and inspect its source URL. Keep publication identity with each claims/assignee export. Save a comparison scope for a small recurring watchlist and review the reported field changes against the source document. Route the resulting evidence to a researcher before making a legal or business decision.

## Check the fit

This reads known public document pages. It does not discover patents by keyword, determine validity or infringement, or provide a complete global patent archive. Bounded claims and citations must be interpreted using the Actor coverage report.

## Real output sample

One selected row from a 2026-11-03 run. Selected original scalar fields from one actual saved observation; nested data and private artifact links are omitted.

Run: R3B7f7CwKpQTOZosU. Summary status: ok. Incomplete: false.

Dated bounded release evidence for this exact input and build. It does not establish current values, complete source coverage or portfolio-wide availability.
