check-a-trademark

check-a-trademark is a skill for Claude Code, Codex from akiotanaka847/qaio-desktop. It costs 80 tokens per session (1,213 once invoked), scanned A, original, MIT.

A quick search of the official US trademark database for a proposed name, including exact, similar-sounding, and visually similar results. It gives a Low, Medium, or High risk rating, but it is not a complete legal clearance.

In plain words
What is it for?
Use it to check a word mark, and where relevant a separate logo or design mark, in the trademark classes covering your planned goods or services.
Why use it?
It helps identify obvious name conflicts before you spend money on branding, domains, or a trademark application. A trademark lawyer is still needed for a full clearance review.

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

check-a-trademark scanned grade A with 0 findings 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 11d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Check a Trademark

Not clearance opinion - knockout. Knockout answer "obvious blocker?" Not "safe to register?" Second question need TM counsel.

When to use

  • "Run knockout on {mark}."
  • "Is {name} available as trademark?"
  • Before any spend on branding, domain, logomark.
  • Before filing 1(b) intent-to-use application.

Steps

  1. Read shared context. Read context/legal-context.md. If missing or empty, ask the user in plain language: "I need to know a few basics about your company first. Want to set those up now?" Then run set-up-my-legal-info if yes. Stop until that's done.

  2. Confirm mark + classes. Founder give:

    • Proposed word mark (design element / logo separate if relevant - design marks need own search).
    • Nice classes they want. Most SaaS founders = Class 9 (software / downloadable apps) + Class 42 (SaaS / platform-as-a-service). Branded consumer hardware add Class 35 (retail services) or product class. Founder unsure → propose 9 + 42, confirm.

    Write config/trademark-prefs.json with { classes, lastSearchedAt } if first-time.

  3. Run knockout vs USPTO Trademark Center. Run composio search uspto or composio search trademark for tool slug; USPTO Trademark Center (launched Jan 2025) = canonical system. No connected tool → run composio search web-scrape and query https://tmsearch.uspto.gov/ direct.

    Four passes per class:

    • Exact-word pass - mark as wordmark.
    • Phonetic pass - phonetic equivalents (Kandi vs Candy, Fone vs Phone, Noot vs Newt, etc.).
    • Visual pass - letter-swap / transliteration (Lyft vs Lift, Tumblr vs Tumbler).
    • Root-word pass - search root if mark compound (e.g. "BrightCloud" → search "Bright" and "Cloud").
  4. Classify each hit. Per result capture: serial number, full mark, owner, goods/services description, class, filing date, status (LIVE / PENDING / ABANDONED / DEAD). LIVE or PENDING hit in overlapping class = blocker. ABANDONED or DEAD = informational (still possible common-law mark issue, not registration blocker).

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.
