Google Patent Documents - Claims, Assignees & Changes

Turn a known patent watchlist into structured evidence for research. Paste publication numbers and receive numbered claims, abstracts, source-reported inventors and assignees, filing/publication dates, CPC classifications and source/PDF links.

This is document lookup and monitoring, not keyword search or a legal-status service.

Start with a real patent

{"patents":["US10000000B2"],"maxResults":1,"maxClaims":30,"maxCitations":30}

Choose Start, then open Patent documents, the JSON export or the readable report. No Google login, source API key, paid proxy or extra subscription is required. For an AI agent, send the same JSON through Apify's API/MCP server and read the dataset with the source URLs intact.

Who this helps

R&D analysts can maintain competitor patent watchlists. Technology scouts can export claim evidence for human review. Research teams can ingest cited documents into a pipeline with stable publication IDs and dated source provenance. The Actor does not discover all patents in a market or determine whether a product infringes a claim.

Output	What it means
publicationId, title, abstract	Exact document identity and source abstract
claims	Numbered claim text, each capped at16000characters
claimsDeclared, claimsParsed, claimsReturned, claimsTruncated	Auditable source/parser/output coverage
inventors, assignees, currentAssignees	Names stated on Google Patents; not independently verified ownership
filingDate, publicationDate, priorityDate	Source-reported document dates
cpcCodes, citedPatents	Bounded classifications and patent-reference identifiers
pdfUrl, url, observedAt	Source-document links and observation timestamp
comparisonStatus, changedFields, previous	Saved comparison when requested

Repeated monitoring

Enable comparePrevious and reuse the same publication IDs, claim/citation limits and snapshot name. The first run establishes a baseline; only confirmed saved rows update history. onlyChanges saves only observed new/changed documents and may correctly return zero rows. History is stored in your account. Use one writer per snapshot. Missing or failed documents never imply a withdrawn patent. Changing parser/output settings can require a new snapshot name.

Scope and limits

Up to ten known publication IDs,100 claims and100 patent citations per document. English document pages are requested; the source may contain translations. The Actor does not download or parse the linked PDF, follow citation chains, search keywords, estimate patent value or supply authoritative legal status. Google Patents coverage is incomplete. Verify important facts against the issuing patent office.

Responses are limited to8MiB, requests are paced and share the run deadline. Only the permitted public document route is fetched. Robots policies are checked; no search-route workaround, login or challenge bypass is used. Missing numbered claims or invalid publication identity fails the source rather than emitting a fake document. Source failures and truncation are reported in SUMMARY; reports are not paid rows.

Pricing

Base price: $0.005 per saved patent document, plus $0.00005 per start at default memory. One document costs$0.00505 at the base rate. Applicable plan discounts and the Store pricing panel govern actual charges. Set a maximum charge in Run options. Skipped unchanged documents and source failures are not billed result rows.

Save your watchlist as an Actor task and attach an Apify Schedule. Integrations can deliver your dataset to Sheets,Make,n8n or your research pipeline; no external messages are enabled automatically.
