SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Proposing a new trademark without any screening risks adopting a mark that is generic, descriptive, or confusingly similar to an existing registration — leading to rejected applications or infringement lawsuits. This Skill performs a structured first-pass trademark triage so obvious problems surface before investing in a full professional clearance search. ## Core Features & Use Cases - Knockout screening: Checks the proposed mark against intrinsic bars — generic, descriptive, deceptive, geographic, surname, false connection, prohibited matter, and functional — with a specific flag or 'no issue' per category. - Similar-marks search: Queries connected trademark and legal research sources (Solve Intelligence, Descrybe, CourtListener) across relevant Nice classes and jurisdictions, with explicit fallback disclosure when no database is connected. - Likelihood-of-confusion factor analysis: Walks the applicable circuit's test (du Pont, Polaroid, Sleekcraft, or EU/UK global appreciation) and flags each factor without ever concluding a mark is clear. - Use Case: A company proposes 'APEXLEAF' for an outdoor apparel line launching in the US and EU. The Skill intakes the mark, goods, classes, and jurisdictions, flags knockout issues, sweeps adjacent word families, and produces a triage memo with recommended next steps for trademark counsel. ## Quick Start Ask the assistant to run a trademark clearance triage on your proposed mark, describing the goods or services and target jurisdictions, for example: run a clearance check on the mark 'APEXLEAF' for an outdoor apparel line launching in the US and EU.

FAQPage Schema
How do I run a trademark knockout search before adopting a new mark?

Provide the proposed mark, the goods or services it covers, and the target jurisdictions. The skill screens for intrinsic bars like genericness and descriptiveness, searches connected trademark databases for similar marks, and produces a flag list for attorney review.

What is the difference between a knockout search and a full trademark clearance opinion?

A knockout search is a quick first-pass triage that catches obvious conflicts and intrinsic bars. A full clearance opinion requires comprehensive searches of TESS, state registries, common law sources, and international registries plus attorney judgment, which this skill explicitly does not provide.

Which likelihood-of-confusion test applies to my trademark?

The test depends on jurisdiction and forum: du Pont for TTAB proceedings, Polaroid in the Second Circuit, Sleekcraft in the Ninth Circuit, and global appreciation under Article 8(1)(b) EUTMR in the EU. The skill selects the framework based on where you plan to enforce.

Can this skill tell me if my trademark is clear to use?

No. The skill never concludes a mark is clear — it only flags potential issues. A 'no obvious conflicts' result means the triage found nothing, not that the mark is safe. A registered trademark attorney must evaluate before adoption or filing.

What happens if no trademark search database is connected?

The output explicitly states that no database search was run and limits the analysis to intrinsic-bar checks and confusion factors against marks you supply. It lists the databases a full professional search must cover as a required next step.

Does the clearance check cover non-English jurisdictions?

It flags the need for translation equivalents, transliteration, and script variations when non-English jurisdictions are in scope, but does not perform cross-language analysis itself. It recommends including that analysis in a professional search for the relevant jurisdiction.
