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

MCP (AI agents)

{
  "mcpServers": {
    "apify": {
      "url": "https://mcp.apify.com?tools=dataspryva/google-patents-inventor-assignee-and-citation",
      "headers": {
        "Authorization": "Bearer <YOUR_APIFY_TOKEN>"
      }
    }
  }
}

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.

What a run costs

The result rate falls on higher Apify plans. Each figure is the published per-result rate times the number of results.

Apify planPer 1,00010,000 results100,000 results
Free plan$0.99$9.90$99
Starter plan$0.82$8.20$82
Scale plan$0.66$6.60$66
Business plan$0.49$4.90$49
  • Every run also has a start event, charged per GB of memory (minimum one): $0.10 on Free, $0.03 on Business. At its default memory of 4 GB a run starts at $0.40 on Free. Fewer, larger runs keep this small.
  • The Free plan includes $5 of monthly usage (Apify pricing, checked 2026-11-11); at the Free rate that covers at most about 5,050 results, less start events and platform usage.
  • Worked example: 10,000 results in one run on the Free plan cost $10.30 ($9.90 for results + $0.40 start), plus Apify platform usage (compute), billed separately by Apify.
  • Pay per event. Platform usage (compute) is billed by Apify on top of the event prices. Compare other tools in the cost estimator.

Where it fits among Google Patents routes

It ranks 1 of 1 catalogue Actors for Google Patents on the published formula (fields, price, reliability, freshness). Its line is highlighted on the map.

Route diagram for Google Patents dataGoogle Patents Inventor, Assignee & Citation Lookup: stops at 4 of the 10 fields shown; Other Store tools (8): stops at 9 of the 10 fields shown; Google Patents Public Datasets on BigQuery: public, field coverage not compared.Google PatentspatentpublicationtitleassigneeprimarystatusabstractfilingDatepdfUrlpriorityDate1+API

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.

Official route: Google Patents Public Datasets on BigQuery

Public API. 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.

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