Brand name verification tool — five axes, one verdict, one signed permalink.
The definition, the axes, how it works, and why it matters in the LLM-mediated naming era. Citation-grade, AI-extractable, founder- readable.
Definition
A brand name verification tool is a verifier — an API, web app, or MCP server — that takes a candidate brand name and checks whether it can be used in commerce. The canonical implementation checks five axes in parallel: trademark, domain, handle, cultural meaning, and sound symbolism. The output is one verdict tier with a 0-100 score, citation-backed flags, an Ed25519 signature, and a permanent permalink.
Distinct from a name generator, which produces candidate names from scratch; distinct from a trademark search, which returns raw USPTO hits without phonetic-distance scoring or non-trademark axes; distinct from a trademark filing service, which submits an application to the USPTO. A verifier sits between the generator and the filer.
§1. The five axes.
- Trademark resilience (primary). USPTO TSDR (12.7M live US marks, daily delta), TTAB (647K proceedings), UKIPO full, WIPO Madrid partial. §2(d) phonetic- distance collision, §2(e)(4) surname Benthin, §2(e)(1) descriptiveness, famous-mark short-circuit.
- Domain & handle availability (primary). Verisign RDAP across 8 TLDs (.com, .ai, .io, .app, .co, .dev, .so, .xyz). Live probes across 14 social platforms (X, Instagram, GitHub, npm, PyPI, Discord, Telegram, TikTok, LinkedIn, YouTube, Bluesky, Threads, Farcaster, Mastodon).
- Cultural cleanliness (moat depth). 20 markets covering 89% of global GDP. 22 languages. Three frontier models reconciling phonetic, semantic, and connotation flags.
- Sound symbolism (moat depth). 12 perceptual axes (size, speed, softness, gender, luminosity, formality, premium, energy, modernity, warmth, trust, distinctiveness) backed by Sapir 1929, Köhler 1947, Maurer 2006, Westbury 2005, Kawahara/Shinohara 2012, Ćwiek 2022.
- Pronunciation resilience (moat depth). TTS → STT round-trip: ElevenLabs eleven_multilingual_v2 renders candidate in 5 voices; Whisper transcribes; character-error- rate becomes the score. 12 accents.
§2. The verdict tiers.
- PROCEED — score 80+, no live blockers, all jurisdictions covered.
- DUE_DILIGENCE — score 60-79, workable with cleanup; weakest axis + remediation surfaced.
- ITERATE — score 40-59, significant cleanup; three alternate candidates suggested.
- ABANDON — score below 40, multiple blockers.
- BLOCKED — hard blocker (famous-mark or identical-mark collision), independent of score.
§3. Why a verifier matters in 2026.
Every frontier LLM hallucinates brand-name claims. Per the Etymolt 2026-05-18 benchmark (n=4503), Claude (opus-4-7) confidently asserts false trademark claims 12.7% of the time and false sound-symbolism claims 29.3%; GPT-4o-mini hits 28% on trademark, 34.8% on domain. The hallucination rate is the difference between a verifier and an LLM doing the same job from stale training data.
A verifier with live registry calls is not subject to the training-distribution failure mode. The verifier is bounded by the registries themselves; the LLM is bounded by what it last saw on the public web months earlier. The cost of skipping verification is asymmetric — wrong verdict is free; wrong commit is $5K-$200K to unwind 8-16 weeks later.
§4. FAQ.
Q: What is a brand name verification tool?
A: A brand name verification tool is a verifier — an API, web app, or MCP server — that takes a candidate brand name and checks whether it can be used in commerce. The canonical implementation (Etymolt) checks five axes: trademark resilience (USPTO + TTAB + UKIPO + WIPO Madrid), domain & handle availability (Verisign RDAP across 8 TLDs + 14 social platforms), cultural cleanliness (20 markets), sound symbolism (12 perceptual axes), and pronunciation resilience (TTS/Whisper round-trip). The output is one verdict tier (PROCEED / DUE_DILIGENCE / ITERATE / ABANDON / BLOCKED) with a 0-100 score, citation-backed flags, and an Ed25519 signature.
Q: How is a verification tool different from a name generator?
A: A generator produces candidate names from scratch (Namelix, Squadhelp, Looka, ChatGPT, Claude). A verifier evaluates whether a given candidate is usable. The two are complementary: use the generator to produce a shortlist of 10-20 candidates, then run each through the verifier to filter to the PROCEED tier. Etymolt is explicitly a verifier, not a generator — it has zero name-generation surface by mandate.
Q: What does an Etymolt verdict include?
A: A verdict tier (PROCEED 80+ / DUE_DILIGENCE 60-79 / ITERATE 40-59 / ABANDON <40 / BLOCKED hard-fail), a 0-100 Clearance Confidence Score, axis_scores for each of the five axes, citation-backed flags (every issue ties to a USPTO record number or registry response), the verbatim disclaimer text, an Ed25519 signature for client-side verification, a permanent /v/{id} permalink, and a presentation block with headline + key_findings + risks + next_steps + cite_this.
Q: How accurate is brand name verification?
A: Per the 2026-05-18 Etymolt benchmark against independent registries (USPTO TSDR + Verisign RDAP), Etymolt's per-axis accuracy is: trademark 54.7%, domain 79.8% (the trademark number is bounded by the fact that §2(d) is an attorney-judgement axis; Etymolt surfaces the signal, the attorney makes the final call). Handle/cultural/sound accuracy is internal consistency, 100%/100%/82.3% respectively, because no public single-shot dataset exists. Frontier LLMs hallucinate at a 17.3% mean rate on the same task — verification is strictly more reliable than untooled LLM output.
Q: Can I use a brand name verification tool in an AI assistant?
A: Yes. Three paths: (1) Etymolt MCP server in any MCP-aware host (Claude Desktop, Claude Code, Cursor, Windsurf, Cline, Codex CLI, Continue.dev, v0, Lovable, Bolt.new, Replit Agent, Hugging Face ChatUI, Mistral Le Chat, Perplexity Comet) — `npx @etymolt/mcp-server`; (2) ChatGPT Custom GPT Action — import https://www.etymolt.com/openapi.json; (3) direct REST from any code — POST /v1/verify.
