Google Patents Details by Number: status, dates, CPC, citations

One structured record per patent publication number from Google Patents, up to 200 per run: title, abstract, assignee, country, priority, filing and publication dates, legal status and expiry, claim count, CPC codes and citation counts. No inventor names. Pay per delivered patent.

Why this scraper

• Only delivered results are charged. Inputs that fail come back as clear error records at no cost.
• Measured on real documents from three offices (US, EP, WO, 15 September 2026): title, assignee, dates, legal status, claim count, CPC codes and citation counts all read server-side, without a browser. The claim markup differs per office and both forms are handled and tested.
• No inventor names. Patents are public records, but inventors are people; this actor delivers the assignee (a company) and leaves the persons out. That keeps the data usable in any jurisdiction without a privacy review.
• By number only, by design. Google's robots.txt allows the document pages and forbids the search pages, so this actor reads exactly what is allowed. Bring your own numbers (from a watch list, a portfolio, a citation list) and get a clean record for each.

Who this is for

Patent analysts, IP teams and competitive-intelligence work that already has lists of publication numbers and needs them enriched fast: legal status and expiry for a portfolio review, CPC codes for landscaping, citation counts as a rough impact signal, assignee and dates for a timeline. Up to 200 numbers per run, one record each.

Who this is not for

• You want to search by keyword, assignee or CPC. Not possible on the allowed route; this actor needs the publication numbers as input.
• You need the full claims text, the description or the drawings. Only counts and metadata are delivered; the document itself stays on Google Patents (the url field).
• You need inventor names. Deliberately not delivered.

Pricing

Pay per event: one patent-delivered event per delivered result. No charge for inputs that fail, no separate platform-usage surcharge.

Free Apify plan: this actor delivers up to 25 rows per run for accounts on the Apify free plan, and then stops with a message. That limit is set by us, not by Apify. It exists so the actor keeps paying for itself for the people who do pay. Any paid Apify plan runs it at full size, billed per delivered row, with failed rows never charged.

FAQ

Which numbers work? Any publication number Google Patents knows: US10000000B2, EP3000000B1, WO2020000001A1, CN, JP, KR and others. A full patents.google.com URL is fine too. Numbers are normalised (spaces, dashes and lowercase are accepted).

What does legalStatus contain? Google's own status label: Active, Ceased, Expired, Pending, Withdrawn. expirationDate is present when Google shows one (granted patents).

Why is claimCount sometimes lower than I expected? It counts the numbered claims on the page. Applications published without claims on Google Patents get 0.

What happens with a number that does not exist? A NOT_FOUND error record and no charge. Blocked requests are retried on a fresh exit before they are reported.

Is any personal data collected? No. Inventor names are on the page and are deliberately left out; the assignee is an organisation.

Is personal data collected? No. Inventor names are deliberately left out; only the assignee (an organisation) is delivered.

What happens when the source changes? Sources change from time to time; that is the nature of this work. The actor is monitored daily and fixed fast, and while it is broken you are not charged, because only delivered results cost anything.
