Google Patents API pricing, limits and access
What the Google Patents Public Datasets on BigQuery costs, who can use it and its published limits, from the official pages, with the catalogue Actors for Google Patents data beside it.
Short answer
Google Patents bibliographic and research tables are available through public BigQuery datasets that require a Google Cloud project. Dataset access is free, while query processing is billed beyond the monthly free allowance.

| Fact | Value |
|---|---|
| Status | Public API |
| Official API | Google Patents Public Datasets on BigQuery |
| Who can use it | Google publishes patent bibliographic data (provided by IFI CLAIMS) and research tables as public BigQuery datasets that anyone with a Google Cloud project can query with SQL. There is no API for the patents.google.com search interface itself |
| Published price | The datasets are free to access; BigQuery query processing is billed, and the first 1 TB processed per month is free |
| Limits | Standard BigQuery quotas apply; a Google Cloud project is required |
What this means in practice
Separate dataset access from query costs
Free access to the patent tables leaves query processing as a separate cost. Check BigQuery pricing when planning repeated analysis, since the amount processed determines whether queries exceed the free allowance.
Plan around BigQuery access and quotas
Queries run through a Google Cloud project under standard BigQuery quotas. Check those quotas before scheduling recurring work, and confirm that the available bibliographic and research tables cover your research task.
