USPTO Database

Use this skill when a task needs official United States patent or trademark records from USPTO systems.

When to Use

• Searching granted patents or pre-grant publications.
• Checking patent application status, file-wrapper data, assignments, or public prosecution history.
• Looking up trademark status, documents, or assignment history.
• Building reproducible prior-art, portfolio, or IP landscape research logs.
• Comparing USPTO records with secondary tools such as Google Patents, Lens.org, Semantic Scholar, or company patent pages.

Do not use this skill to give legal advice. Treat it as a data-gathering and record-verification workflow.

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 data and file wrapper records.
• PatentSearch API: PatentsView search API for granted patents and pre-grant publication datasets.
• 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 only as convenience indexes. When the answer matters, cross-check the official record.

Authentication and Secrets

Many USPTO API flows require an API key. Store keys in environment variables or a secret manager, never in committed files or pasted transcripts.

Common environment names:

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 and rate-limit guidance.

PatentSearch Workflow

Use PatentSearch for broad patent and pre-grant publication search when the question is about trends, inventors, assignees, classifications, dates, or portfolio slices.

Workflow:

1. Identify the endpoint from the current PatentSearch reference or Swagger UI.
2. Build a JSON query with explicit filters.
3. Request only the fields needed for the analysis.
4. Sort and paginate deterministically.
5. Record the endpoint, query body, date, data currency note, and result count.

Python request skeleton:

import os
import requests

API_KEY = os.environ["PATENTSVIEW_API_KEY"]
BASE = "https://search.patentsview.org/api/v1"

payload = {
    "q": {
        "_and": [
            {"patent_date": {"_gte": "2024-01-01"}},
            {"assignees.assignee_organization": {"_text_any": ["Google", "Alphabet"]}},
        ]
    },
    "f": ["patent_id", "patent_title", "patent_date"],
    "s": [{"patent_date": "desc"}],
    "o": {"per_page": 100, "page": 1},
}

response = requests.post(
    f"{BASE}/patent/",
    headers={"X-Api-Key": API_KEY, "Content-Type": "application/json"},
    json=payload,
    timeout=30,
)
response.raise_for_status()
print(response.json())

Before reusing a query, verify current endpoint names, field paths, request parameters, and API-key availability in the live PatentSearch docs.

Trademark/TSDR Workflow

Use TSDR when the task needs trademark case status, documents, images, owner history, or prosecution events.

Workflow:

1. Normalize the serial number or registration number.
2. Check the current TSDR API instructions and required API-key header.
3. Fetch status first, then documents only if needed.
4. Respect the lower rate limit for PDF, ZIP, and multi-case downloads.
5. Capture retrieval date and serial/registration identifier in the output.

For large trademark pulls, prefer documented bulk-data flows rather than screen-scraping public pages.

File Wrapper and Prosecution History

For application status, transaction history, and prosecution documents:

• Start with ODP Patent File Wrapper search.
• Use exact identifiers when available: application number, publication number, patent number, or party name.
• Record whether the record is a granted patent, pre-grant publication, or pending application.
• Cross-check document dates and status against the record detail page before citing them.

Assignment Workflow

For patent or trademark ownership:

1. Search official assignment data by patent/application/registration number, assignor, assignee, or reel/frame when available.
2. Record conveyance text, execution date, recordation date, and parties.
3. Distinguish assignment records from current legal ownership conclusions.
