USPTO Database

Overview

USPTO data for patents and trademarks: application and patent bibliographic search, examination (prosecution) history, continuity, assignments, office actions, PTAB proceedings, and trademark status (TSDR), for IP analysis and prior art searches. Most patent APIs now live on the USPTO Open Data Portal (ODP) at https://api.uspto.gov; several older services were retired in 2025–2026, so check the status table below before reusing older code.
