Route map

Each line is one way to get Google Patents data; each stop is a field you probably need. Green lines are catalogue Actors, ranked by the published formula.

Stops are fields. A ring means the field is in that route's published output schema; no ring means the line passes without it. Bold labels are the core fields for this website, the rest are fields that differ between routes. A white capsule means every data line stops there. The red line is the official API; its field coverage is not compared. A crossed red line means there is no open official API.

Field dictionary: the exact keys

The same core field has a different key in each Actor's output. Map these before you merge datasets; a dash means the published schema has no matching key. Need a field that is not listed here, such as email? Search every Google Patents Actor by field.

All 9 tools, scored

Catalogue Actors link to their detail pages; the score (0 to 100) is the published formula, identical for every tool. Other Store tools follow in their own table, for reference. Price is the published primary-result rate per 1,000 (the Free-plan rate where the price is tiered; higher Apify plans pay less); start events and platform usage are excluded.

Official API route

Google Patents Public Datasets on BigQuery

Google publishes patent bibliographic data (provided by IFI CLAIMS) and research tables as public BigQuery datasets that anyone with a Google Cloud project can query with SQL. There is no API for the patents.google.com search interface itself.

Price. The datasets are free to access; BigQuery query processing is billed, and the first 1 TB processed per month is free.

Limits. Standard BigQuery quotas apply; a Google Cloud project is required.

Official documentation Official pricing

Patent documents are public records, but Google's terms bar automated access that ignores robots.txt. This is general information, not legal advice.

Read Google Patents' terms. Keep to public data, do not bypass logins or access controls, and check whether personal data is involved before you collect it. The can-I-scrape checklist walks through it.

  2. Set the Google Patents search, profile, listing or URL you need and a result limit; the required input is mode.
  3. Run it and export the dataset as JSON, CSV or Excel, or call it from the Apify API.

Waits for the run and returns the dataset items (runs over 300 seconds return HTTP 408; start an async run instead).

MCP (AI agents)

Adds this Actor as a tool in an MCP client that takes a remote server URL (Cursor, VS Code, Claude Code) through Apify's hosted MCP server. OAuth sign-in also works without the header. Clients that only start local servers can wrap the URL with npx mcp-remote.
