What is uspto-database?

A connection to the United States Patent and Trademark Office, the government agency that records US patents and trademarks. It provides searchable records, examination history, ownership changes, citations, and office actions.

Use it for prior-art searches, patent and trademark status checks, ownership tracking, citation analysis, and portfolio research.

It avoids searching several patent and trademark systems manually when checking intellectual-property records.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00040	$0.04546
Opus 5	$0.00020	$0.02273

Security

Grade A, and why

uspto-database scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/patent_search.py, scripts/peds_client.py, scripts/trademark_client.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

USPTO Database

Overview

USPTO provides specialized APIs for patent and trademark data. Search patents by keywords/inventors/assignees, retrieve examination history via PEDS, track assignments, analyze citations and office actions, access TSDR for trademarks, for IP analysis and prior art searches.

When to Use This Skill

This skill should be used when:

Patent Search: Finding patents by keywords, inventors, assignees, classifications, or dates
Patent Details: Retrieving full patent data including claims, abstracts, citations
Trademark Search: Looking up trademarks by serial or registration number
Trademark Status: Checking trademark status, ownership, and prosecution history
Examination History: Accessing patent prosecution data from PEDS (Patent Examination Data System)
Office Actions: Retrieving office action text, citations, and rejections
Assignments: Tracking patent/trademark ownership transfers
Citations: Analyzing patent citations (forward and backward)
Litigation: Accessing patent litigation records
Portfolio Analysis: Analyzing patent/trademark portfolios for companies or inventors

USPTO API Ecosystem

The USPTO provides multiple specialized APIs for different data needs:

Core APIs

PatentSearch API - Modern ElasticSearch-based patent search (replaced legacy PatentsView in May 2025)
- Search patents by keywords, inventors, assignees, classifications, dates
- Access to patent data through June 30, 2025
- 45 requests/minute rate limit
- Base URL: https://search.patentsview.org/api/v1/
PEDS (Patent Examination Data System) - Patent examination history
- Application status and transaction history from 1981-present
- Office action dates and examination events
- Use uspto-opendata-python Python library
- Replaced: PAIR Bulk Data (PBD) - decommissioned
TSDR (Trademark Status & Document Retrieval) - Trademark data
- Trademark status, ownership, prosecution history
- Search by serial or registration number
- Base URL: https://tsdrapi.uspto.gov/ts/cd/

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
