markenrecherche

markenrecherche is a skill for Claude Code, Codex from ThomasMoreAI/legal-skills-open. It costs 121 tokens per session (2,596 once invoked), scanned A, original, Apache-2.0.

A trademark clearance check for a proposed brand, product name, logo, slogan, colour, or shape. It searches earlier trademark records and reviews possible conflicts across selected countries and product or service classes.

In plain words
What is it for?
Use it to check a proposed mark, compare it with earlier registrations, and prepare a structured research package for legal review.
Why use it?
It helps find confusingly similar earlier trademarks before a launch, rebrand, domain registration, or application. The result supports a lawyer’s decision but is not a final legal approval.

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

markenrecherche 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 9d 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.

Markenrecherche (Clearance)

Zweck

Erste Verwechslungsrisikoprüfung für eine geplante Marke oder Unternehmensbezeichnung. Der Skill führt einen Knockout-Scan durch, identifiziert potenziell kollidierende Voreintragungen und analysiert die relevanten Verwechslungsfaktoren. Ergebnis ist ein Recherchepaket für den beratenden Anwalt – kein Freigabe- oder Sperrurteil. Einsatzfelder: Produktneueinführungen, Rebranding, Domainregistrierungen, Unternehmensneugründungen.

Eingaben

  • Zu prüfendes Zeichen (Wort, Bildmarke, kombiniertes Zeichen, Slogan, Farbe, Form)
  • Gewünschte Waren- und Dienstleistungsklassen (Nizza-Klassifikation, 12. Ausgabe)
  • Zielländer / Zieljurisdiktionen (DE, EU/EUTM, international/Madrid)
  • Verwendungskontext und Branche

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.
