Google Patents Scraper - Patent Search, Inventors & Dates

Search Google Patents in bulk and get structured rows instead of a results page. Publication number, inventor, assignee and the full date chain - priority, filing, grant and publication - for every hit, across as many queries as you need.

⭐ bulk patent queries · inventor & assignee · priority/filing/grant dates · deep pagination · pay per row delivered · CSV/JSON/Excel · API, MCP & schedules

What data does it extract?

One row per patent, with the query, page and type it came from so multi-query exports stay separable. Fields Google does not return for an item are simply absent, and any new field Google adds is passed through automatically.

Field	Description
title	Patent title
snippet	Abstract extract Google shows
link	Google Patents URL
publicationNumber	Publication number, e.g. KR101786497B1
inventor	Inventor name
assignee	Assignee or owner
priorityDate	Priority date
filingDate	Filing date
grantDate	Grant date, where granted
publicationDate	Publication date
position	Rank within the page
query	The query this row came from
page	Which results page it came from

How to use it

1. Paste your queries into queries - one per line.
2. Set the options you need from the table below.
3. Run it, then download the dataset as CSV, Excel, JSON, JSONL or XML - or read it straight from the Apify API.

Input example

{
  "queries": [
    "coffee machine",
    "solar panel mounting"
  ],
  "maxPages": 5
}

Option	Type	Description
queries	array	Required. Search queries, one per line.
gl	string	Country code - us, in, gb, de...
hl	string	Language code - en, hi, es...
maxPages	integer	Pages per query, default 1. Each page is one request.

Pricing

Event	Price
patent-result	$1.49 per 1,000 patents ($0.00149 per patent)

1,000 patents → $1.49 · 10,000 → $14.90 · 100,000 → $149.00

You are billed per row delivered, as it is delivered. Queries that fail or return nothing cost you nothing, and an interrupted run only ever bills the rows already in your dataset.

Use cases

Run prior-art and freedom-to-operate sweeps at scale

Fire dozens of phrasings of the same concept in one run and collect every hit with its date chain, instead of paging the site by hand.

Monitor a competitor's filings

Query by assignee name on a schedule and watch new publication numbers and grant dates appear.

Map a technology landscape

Export hits across a keyword set, then group by assignee and filing year to see who is investing where.

Find inventors and assignees for partnerships or hiring

The inventor and assignee columns turn a technical topic into a list of the people and organisations actually building in it.

Build patent datasets for analysis

Structured dates and publication numbers make downstream joins and time-series analysis simple.

Good to know

• About 10 patents per page; maxPages controls depth.
• Date filtering happens in your own tooling - the date columns are there for it.
• Grant date is absent for applications that have not been granted.

Frequently asked questions

Do I need proxies, an API key or a Google account?

No. Requests run through hosted Google search infrastructure on our side - nothing to configure.

How many patents can I get per query?

About 10 per page. Use maxPages (up to 100) for depth - each page is one request, so 10 pages returns roughly 100 patents per query.

Do I get the full patent text or claims?

No. You get the searchable record - title, abstract extract, numbers, parties and dates - plus the link to the full document on Google Patents.

Which jurisdictions are covered?

Whatever Google Patents indexes, including US, EP, WO, CN, JP, KR and more. The publication number prefix tells you the jurisdiction.

Can I filter by date?

Not through a date option - Google Patents ignores the recency filter. Export the rows and filter on filingDate, priorityDate or grantDate in your spreadsheet or database instead.

How do I export patent search results to CSV or Excel?

Download the run's dataset as CSV, Excel, JSON, JSONL or XML, or read it via the Apify API.

Am I charged for queries that return nothing?

No. Billing is per row delivered.
