# USPTO Database Use this skill when a task needs official United States patent or trademark records. This is a data-gathering and record-verification workflow — do not use it to give legal advice. ## When to Use - Searching granted patents or pre-grant publications - Checking patent application status, file-wrapper data, assignments, or prosecution history - Looking up trademark status, documents, or assignment history - Building reproducible prior-art, portfolio, or IP-landscape research ## Source Selection Prefer official USPTO or USPTO-supported surfaces first: - **Open Data Portal (ODP)** — current home for migrated USPTO datasets and APIs - **Patent File Wrapper** — public patent application bibliographic and file-wrapper records - **PatentSearch API** — PatentsView search API for granted patents and pre-grant publications - **TSDR Data API** — trademark status and document retrieval - **Patent and Trademark Assignment Search** — ownership transfer records - **PTAB data in ODP** — Patent Trial and Appeal Board proceedings Use secondary sources (Google Patents, Lens.org) only as convenience indexes; cross-check the official record when the answer matters. ## Authentication Many USPTO API flows require an API key. Store keys in environment variables or a secret manager. ```bash export USPTO_API_KEY="..." export PATENTSVIEW_API_KEY="..." ``` For PatentSearch, send the key with the `X-Api-Key` header. For TSDR, follow the current USPTO API Manager instructions an
