US Patents Scraper — Search Patents by Keyword, Assignee & Inventor (No API Key)

▶️ Run the US Patents Scraper on Apify →

This repository is documentation only. The scraper itself runs as a hosted Actor on the Apify platform — no setup, no infrastructure, no code to maintain.

Scrape patent search results by keyword, assignee (owner company), inventor name, date range and patent office in a single run. The US Patents Scraper turns a plain search query into a clean, structured dataset of patents — patent ID, title, publication & filing dates, abstract, assignees, inventors, CPC classification, patent type, claim count and direct links to the patent page and PDF. Search US patents by default, or switch to any major office worldwide (EP, WIPO/PCT, JP, CN, KR, DE, GB and more). No API key, no login, no developer account — just a query and you get hundreds to thousands of patents back.

Leave every filter empty and the Actor returns the most recent patents automatically, so you always get a live feed. Use it as an unofficial patent search API alternative for competitive intelligence, prior-art discovery, IP landscaping, technology scouting and R&D analytics.

📤 What you get (output fields)

Every run writes one structured row per patent to your Apify dataset. Fields:

Field	Description
patent_id	Publication number (e.g. US12615098B2).
title	Patent title.
patent_date	Publication or grant date (YYYY-MM-DD).
filing_date	Application filing date (YYYY-MM-DD).
priority_date	Earliest priority date (YYYY-MM-DD).
abstract	Abstract snippet.
assignees	Assignee / owner company name(s).
inventors	Inventor name(s).
cpc_class	Cooperative Patent Classification code(s).
type	Detected type: grant, application, utility, design or patent.
num_claims	Claim count when available.
patent_url	Patent page URL.
pdf_url	Direct PDF URL when available.
country	Two-letter office / country code from the publication number.
status	Legal status stage when available.

💡 Use cases

• Competitive IP intelligence — track every new patent filed by a rival company by setting assignee to their name (e.g. Samsung, Apple, Tesla).
• Prior-art & freedom-to-operate search — pull all patents matching a technical keyword before filing, to surface conflicting claims early.
• Technology scouting & landscaping — map who is patenting in a field (e.g. solid-state battery, mRNA, LiDAR) and how activity trends over time by publication date.
• R&D and innovation analytics — build a dataset of CPC classes, claim counts and filing dates to quantify a technology area or a company's portfolio.
• Inventor & talent tracking — follow a named inventor's output across companies with the inventor filter.
• M&A and investment due diligence — assess a target's patent footprint (volume, assignees, recency) as part of technical due diligence.
• Academic & policy research — assemble structured, exportable patent datasets for bibliometric and innovation studies.
• Patent monetization & licensing — find licensable patents in a niche by keyword and assignee, with direct links to the full document and PDF.

🚀 Quick start (4 ways)

1. Open the US Patents Scraper and click Try for free.
2. Type a keyword in Search Query (or leave everything empty for the newest patents), optionally add an Assignee or Date From/To.
3. Click Start, then open the Output tab and export to JSON, CSV or Excel.

2) Apify CLI

npm install -g apify-cli
apify login
# Run with default input (newest patents)
apify call logiover/patentsview-scraper

3) API / curl (run and get results in one call)

curl -X POST "https://api.apify.com/v2/acts/logiover~patentsview-scraper/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "machine learning",
    "assignee": "Google",
    "dateFrom": "2023-01-01",
    "countryCode": "US",
    "maxResults": 200
  }'

4) apify-client (JavaScript & Python)

See examples/javascript.md and examples/python.md. More curl recipes in examples/api-curl.md and CLI recipes in examples/cli.md.

📥 Input

All inputs are optional — run it as-is to get the most recent patents.

Field	Type	Description
query	string	Keyword(s) to search in patent titles and abstracts (e.g. battery, solar panel). Leave empty for the newest patents.
assignee	string	Filter by assignee / owner company (e.g. Samsung, Apple, Tesla).
inventor	string	Filter by inventor last name or full name (e.g. Smith, John Smith).
dateFrom	string	Only patents published on/after this date (YYYY-MM-DD).
dateTo	string	Only patents published on/before this date (YYYY-MM-DD).
countryCode	select	Patent office. Default US. Choose All offices for worldwide, or pick EP, WO, JP, CN, KR, DE, GB, FR, CA, AU, IN, RU, BR, ES, IT, NL, CH, SE, TW.
sort	select	relevance, new (newest first) or old (oldest first). Newest-first is used automatically when no filters are set.
maxResults	integer	Max patents to scrape. Default 200. Set 0 to pull everything available (capped at ~10,000 per query).
proxyConfig	object	Proxy settings. Apify Proxy (automatic) is recommended.

Dropdowns: countryCode and sort are select menus in the Console. Set countryCode to ALL for a worldwide search across every office.

🔌 Integrations & automation

Because the scraper runs on Apify, you can plug patent data into anything:

• Schedules — run daily/weekly to monitor new patents from a competitor (assignee) or in a technology field (query).
• Webhooks — trigger a downstream workflow the moment a run finishes.
• Google Sheets / Airtable — auto-append new patents to a tracking sheet.
• Amazon S3 / storage — archive each run's dataset.
• Zapier · Make · n8n · Pipedream — connect via the Apify integrations to route new patents into Slack, email, a database or a BI dashboard.
• Apify API — start runs and pull the dataset programmatically from your own backend.

📄 Export formats

Download any run's dataset as CSV, JSON, JSONL, Excel (XLSX) or XML from the Console, or fetch it through the Apify Dataset API in the format you need.

❓ FAQ

How do I search patents by keyword without an API key?

Open the US Patents Scraper, type your keyword into Search Query, and run it. No developer account, OAuth or API key is required — you get structured patent results (title, assignee, inventors, dates, CPC, claims and links) back as a dataset.

Is this a patent search API alternative?

Yes. It works as an unofficial patent search API alternative — you send a query, assignee, inventor or date range and receive clean, structured patent data without stitching together an official API, keys or pagination logic.

Can I scrape patents by company (assignee)?

Yes. Set the assignee field to a company name such as Apple, Samsung or Tesla to pull that company's patents. Combine it with dateFrom/dateTo to track only recent filings.

Can I search patents from offices other than the US?

Yes. Set countryCode to any supported office — EP (Europe), WO (WIPO/PCT), JP, CN, KR, DE, GB, FR and more — or choose All offices for a worldwide search.

How many patents can I get in one run?

Hundreds to thousands. Use maxResults to bound a run (default 200), or set it to 0 to pull everything available for the query (capped at ~10,000 results per query).

How do I export patent data to Excel or CSV?

Run the Actor, then download the dataset as Excel, CSV, JSON or XML from the Apify Console, or pull it via the Apify API — a ready patent-data export for spreadsheets and databases.

Does it include the patent abstract, CPC class and claim count?

Yes. Each row includes an abstract snippet, the cpc_class classification code(s), the detected type (grant/application/utility/design) and num_claims when available, plus links to the patent page and PDF.

Can I get only the newest patents?

Yes. Leave the search fields empty (or set sort to new) and the Actor returns the most recent patents automatically — ideal for a scheduled "latest patents" feed.

How do I do a prior-art search with this?

Set query to the core technical terms of your invention and (optionally) a date range, then review the returned titles, abstracts and CPC classes for conflicting claims — a fast first-pass prior-art and freedom-to-operate scan.

Is it free?

The Actor runs on Apify's pay-per-result model with a free tier to start — try it, then scale up. See the Pricing tab on the Actor page.

📝 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.
• Recovered the Actor's missing README from the maintained canonical documentation copy after the live Apify source was found to contain only a broken ../README.md pointer; all 15 documented output fields match the typed dataset contract and retained live samples.
