· TWO REAL RESPONSES, PULLED LIVE 2026-09-05 ·
The problem

Bulk patent data runs behind

Google Patents shows new filings the day they publish. The official route to the data is a bulk dataset in BigQuery, refreshed on Google’s schedule, and it is not a search.

official live Google Patents APIs
1
batch dataset, refreshed on Google’s schedule
What that costs youPrior-art checks on stale data. Competitor filings you see late. A query engine you build yourself.
The fix

A live read of Google Patents does not

CrustAPI reads Google Patents the moment you ask. Every result for your query with assignee, inventor, filing, grant and publication dates, the abstract, the PDF and the figures, in 1.4 seconds.

What Google Patents shows today Dates as real dates PDF and figures included Empty searches are free

You get the record. Cheaper. Fresher. Easier.

Live read : noun

We read the page the moment you ask. Not a copy from last month.

The process

Here’s how you get the patents you want

STEP 1
1

Your patents in one line. Or no code at all

Type what you would type into Google Patents, in the playground or in one line of code. A technology, an assignee, an inventor.

Zero setup. Zero babysitting.

Ten records. Right now

Each with the title, assignee, inventor, the four dates, the publication number, the abstract, a PDF and the figures. Ready for a spreadsheet, a prior-art check or your model.

FAQ

Common questions

One request that returns Google Patents results for a query as data: title, publication number, assignee, inventor, the four dates, abstract, PDF and figures. Google offers a bulk dataset, not a live search API; this reads the public results anyone sees.

Yes. Each record carries the PDF link and the figure links Google shows.

Ten a page, in Google’s order. Ask for the next page for more.

1.4 seconds. That is the median a customer sees, measured through crustapi.com on the day this page was built.

$1.00 for every 1,000 searches, with lower rates for larger individual deposits. A search that returns nothing costs nothing. $6 free every month, no card.

We read the public results Google shows anyone, logged out, and never use accounts or captcha tricks. Public, logged-out collection has repeatedly defeated computer-fraud and contract claims. Check your own use case. We are not lawyers.
