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.

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 4d ago.

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

  1. 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/
  2. 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
  3. 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 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.
