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.
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.
You get the record. Cheaper. Fresher. Easier.
We read the page the moment you ask. Not a copy from last month.
1.4 seconds. One bill. Nothing to babysit.
Type what you would type into Google Patents, in the playground or in one line of code. A technology, an assignee, an inventor.
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.
| Field | What comes back |

| link | https://patents.google.com/patent/US11239459B2/en |
| + priority and publication dates, abstract, PDF, figures and the other records on this query | |
Ask for the next pages until the query runs dry. Run it again weekly and you see every new filing in your field.
| Ask for | What comes back |
|---|---|
| page=2 | the next ten records |
| the same search | today’s results, new filings included |
| scholar | the papers behind the patents |
| + search, news, images and 9 more | |
You get the rows you want. Right today. For less.
The moment you ask. Every record Google Patents shows for your query, with assignee, inventor, dates and links.
Google Patents changes its pages all the time. We keep the read working through every change, so you never run, patch or babysit a scraper.
Four dates parsed. Assignees and inventors as their own fields. PDF and figures as direct links.
You pay only when data comes back. Empty results cost nothing. Report a wrong result and the money comes back.
Stuck on a field, a filter or a weird result? Email support@crustapi.com and a data expert answers within a day. Not a bot.
Plug in our MCP server. Your agent does the rest, paying per result.

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.
Search, Maps, reviews and 9 more. One account, one bill.
