## Pricing

from $1.99 / 1,000 results

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Google Patents Scraper — Search Patents by Assignee, Inventor & Date (No API Key)

Search **millions of patents** on Google Patents and export them as structured data — **no API key, no login**. A single query can match hundreds of thousands of patents; this actor paginates up to Google's 10,000‑result window per query and returns clean bibliographic records.

Google Patents has **no official API**, and paid providers (SerpApi, Scrapingdog) charge for exactly this. This actor talks to the same public `xhr/query` endpoint the website uses.

> ⚠️ Google blocks datacenter IPs on this endpoint. The actor uses **Residential proxy by default** — keep it on.

### What you get per patent

```json
{
  "patentId": "US11074495B2",
  "url": "https://patents.google.com/patent/US11074495B2/en",
  "title": "System and method for extremely efficient image and pattern recognition…",
  "abstract": "Specification covers new algorithms, methods, and systems for Artificial Intelligence…",
  "inventor": "Lotfi A. Zadeh",
  "assignee": "Z Advanced Computing, Inc.",
  "priorityDate": "2013-02-28",
  "filingDate": "2018-03-12",
  "grantDate": "2021-07-27",
  "publicationDate": "2021-07-27",
  "publicationNumber": "US11074495B2",
  "language": "en",
  "pdfUrl": "https://patentimages.storage.googleapis.com/…/US11074495.pdf",
  "thumbnailUrl": "https://patentimages.storage.googleapis.com/…D00000.png",
  "figureCount": 12,
  "source": "google-patents"
}
```

### Example inputs

**Free‑text + date range:**

```json
{ "queries": ["solid state battery", "mRNA vaccine"], "after": "2019-01-01", "dateType": "priority" }
```

**All patents by a company, newest first:**

```json
{ "queries": [""], "assignee": "NVIDIA", "sort": "new", "countries": ["US"], "status": "GRANT" }
```

**Reuse an advanced‑search URL:**

```json
{ "searchUrls": ["https://patents.google.com/?q=drone&assignee=DJI&before=priority:20230101"] }
```

### Filters

- **assignee** / **inventor** — by company/owner or inventor name
- **after** / **before** + **dateType** — priority / filing / publication date range
- **countries** — `US`, `EP`, `WO`, `CN`, `JP`, …
- **status** — granted vs applications
- **patentType** — utility vs design
- **language** — English, German, Chinese, …
- **sort** — relevance / newest / oldest

### Use cases

- **Competitive & IP intelligence** — monitor a competitor's entire patent portfolio.
- **Prior‑art & freedom‑to‑operate** — bulk pull a technology space for review.
- **R\&D and tech scouting** — track filings by topic, assignee, or inventor over time.
- **Datasets** — build patent corpora for analytics or ML without a paid API.

### FAQ

**Do I need a Google/API key?** No. It reads a public endpoint.

**Why residential proxy?** Google returns a block page to datacenter IPs on this endpoint. Residential is the default and is required.

**How many patents per query?** Up to 10,000 (Google's 100‑page × 100‑result window). Use date ranges or assignee filters to slice larger spaces into multiple runs and go beyond that.

**Can I get the full patent text / claims?** This actor returns the search record (title, abstract snippet, bibliographic data, PDF link). Open the `pdfUrl` for the full document.

### 📝 Changelog

#### 2026-08-01

- Completed the August 2026 full health check: verified empty/programmatic default, Console UI default, and two source-informed alternative inputs on Apify.
- Confirmed successful live execution, non-empty structured output, dataset-field/type integrity, and logical sample quality within the 5-minute quality window.
- Declared 18 dataset fields from typed live cloud samples so the output contract is no longer an empty placeholder.
- Declared 18 nullable dataset fields from typed live cloud samples so the output contract is no longer an empty placeholder or brittle to sparse modes.
