Uspto Rate Limits

USPTO does not publish a unified API rate-limit policy. Some APIs (e.g. TSDR) require a free API key and reference per-API "API Key Usage FAQs" for quotas; specific per-second numbers are documented at the individual API level rather than centrally. Migration to data.uspto.gov is in progress.

Uspto Rate Limits is the machine-readable rate-limit profile for USPTO on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 1 rate-limit definition, measuring varies.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Federal Government, Intellectual Property, and Rate Limiting.

Policies

Per-API Documentation
Each USPTO API exposes its own key-usage and quota documentation; consumers should review the relevant FAQ before integrating.
Bulk Data Alternative
For high-volume access, USPTO offers bulk data downloads via the Bulk Data Storage System; prefer those over high-frequency API polling.
