## 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.

## USPTO Patent Assignments Scraper: Owners, Reel/Frame & Patents
> Extract USPTO patent assignment (ownership-transfer) records with assignors, assignees (company + full address), conveyance type, execution and recorded dates, reel/frame, correspondent and the assigned patent/application numbers. Search by assignee, assignor, patent, application, publication or reel/frame.
**📥 [Input](https://apify.com/scrapers_lat/uspto-patent-assignments-scraper/input-schema) · 📤 [Output](https://apify.com/scrapers_lat/uspto-patent-assignments-scraper/output-schema) · 💰 [Pricing](https://apify.com/scrapers_lat/uspto-patent-assignments-scraper/pricing) · ▶️ [Examples](https://apify.com/scrapers_lat/uspto-patent-assignments-scraper/examples)**
Assignor & assignee company + full address
Conveyance, dates & reel/frame plus patent/application numbers
JSON / CSV / Excel output formats
### What you get
For every recorded assignment the scraper returns:
- **Reel/Frame** identifier and **conveyance** type (assignment, merger, security interest, name change...)
- **Assignors** (previous owners) with execution dates
- **Assignees** (new owners) with **company name and full address** (street, city, state, ZIP, country)
- **Execution**, **recorded**, **mail** and **receipt** dates
- The assigned **patent numbers**, **application numbers**, **publication numbers** and the first invention title
- **Correspondent**, attorney docket number, page count and the recorded-document image URL
No result means no charge: you are only billed for real assignment records that were returned.
### Who is it for
| Use case | Who benefits |
|---|---|
| M\&A and competitive intelligence | Analysts tracking who is buying, selling or pledging patents |
| Corporate lead generation | Vendors targeting companies by assignee name + address |
| IP due diligence | Confirming chain of title, security interests and ownership changes |
| Investors and researchers | Monitoring portfolio moves, mergers and name changes |
### How to use it
1. Choose **Search by** (assignee name, assignor name, patent number, application number, publication number, reel/frame or correspondent).
2. Add one or more **search values** (for example `IBM`, `Google`, or a patent number).
3. Optionally enable **Fetch full assignment details** for assignee addresses and patent/application numbers.
4. Set **Max Assignments** and run. Export as JSON, CSV or Excel, or pull it through the Apify API.
### Frequently Asked Questions
**What is a patent assignment?**
It is a recorded transfer of patent ownership or rights — an assignment, merger, security interest (lien) or name change — filed with the USPTO. Each is identified by a reel and frame number.
**Do I get the new owner's address?**
Yes. With details enabled, each record includes the assignee's company name and full mailing address, plus every assigned patent and application number.
**Can I find every assignment for a company?**
Yes. Search by assignee name to find where a company acquired rights, or by assignor name to find what it sold or pledged.
**How fresh is the data?**
Every record is read live at run time, so it reflects the register at the moment of the run (see observedAt).
### Export, API and AI agents (x402 + MCP)
Export the scraped data to **JSON, CSV or Excel**, pull it as a **dataset** through the Apify **API**, or wire it into your app with **no code**. This web scraper and data extractor also works for bulk data extraction and scheduled runs.
For AI agents: this Actor is available on **x402**, Apify's agentic payment standard built with Coinbase. An AI agent can discover, pay for and run it on its own with a funded wallet and a single HTTP request: no account, no subscription, no API key and no human in the loop. It also runs as an **MCP** tool inside Claude, Cursor and other AI clients out of the box. Learn more about [x402 agentic payments on Apify](https://docs.apify.com/platform/integrations/x402).
