What is busqueda-marca?

A preliminary trademark-availability search that compares a proposed brand name with earlier marks in Spanish, European and international registers.

It is for screening a proposed name, considering its goods or services and territory, and assessing the risk that earlier marks could cause confusion.

It helps identify possible conflicts before filing or using a mark. The check is preliminary and focuses on visual, spoken and meaning-based similarity.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00022	$0.01114
Opus 5.5	$0.00009	$0.00446
Sonnet 5.5	$0.00004	$0.00223
Haiku 4.5	$0.00002	$0.00111

Security

Grade A, and why

busqueda-marca 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 17d 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.

Propósito

Esta skill realiza un análisis preliminar (knockout check) de disponibilidad de una denominación como marca. Evalúa el riesgo de confusión con marcas anteriores en los registros OEPM, EUIPO y OMPI, aplicando criterios de similitud visual, fonética y conceptual.

Instrucciones

Paso 1 — Recopilar datos de la marca candidata

Denominación: nombre exacto de la marca propuesta.
Tipo de marca: denominativa, figurativa, mixta, tridimensional, sonora.
Clases de Niza: productos/servicios que se pretende proteger.
Territorio: España (OEPM), UE (EUIPO), internacional (OMPI/Madrid).

Paso 2 — Definir estrategia de búsqueda

Criterios de búsqueda por similitud:

Visual: comparación gráfica de los signos.
Fonética: pronunciación similar, sustitución de letras con sonido equivalente.
Conceptual: significado o asociación semántica equivalente.

Variaciones a considerar:

Singular/plural.
Con y sin artículos o preposiciones.
Traducciones a otros idiomas oficiales de la UE.
Abreviaturas y acrónimos.
Errores ortográficos comunes.

Paso 3 — Analizar resultados

Para cada marca anterior encontrada:

Titular y estado (vigente, en trámite, caducada).
Clase(s) de Niza y descripción de productos/servicios.
Territorio de protección.
Similitud: visual + fonética + conceptual = riesgo global.
Prioridad (fecha de solicitud/registro).

Paso 4 — Evaluar riesgo global

BAJO: No se encuentran marcas similares en clases relevantes.
MEDIO: Existen marcas con alguna similitud pero en clases distintas o con diferencias significativas.
ALTO: Marcas similares registradas o en trámite en las mismas clases y territorio.
KNOCKOUT: Marca idéntica vigente para productos/servicios idénticos o similares.

Formato de salida

## Screening de marca

**Marca candidata:** [denominación]
**Tipo:** [denominativa/figurativa/mixta]
**Clases de Niza:** [lista]
**Territorio:** [España/UE/Internacional]
**Fecha del análisis:** [fecha]

### Resultado del knockout check

**Riesgo global:** [BAJO/MEDIO/ALTO/KNOCKOUT]

### Marcas anteriores relevantes

| # | Marca | Titular | Registro | Clases | Estado | Similitud visual | Similitud fonética | Similitud conceptual | Riesgo |
|---|-------|---------|----------|--------|--------|------------------|--------------------|----------------------|--------|
| 1 | [marca] | [titular] | [OEPM/EUIPO/OMPI nº] | [clases] | [estado] | [A/M/B] | [A/M/B] | [A/M/B] | [nivel] |

### Análisis de confusión

[Para cada marca de riesgo ALTO, análisis detallado de la similitud aplicando los criterios EUIPO]

### Recomendaciones

- [Proceder con registro / Modificar denominación / Descartar / Solicitar opinión especializada]

### Limitaciones de este análisis

- Búsqueda preliminar — no sustituye búsqueda profesional de similitudes.
- No cubre marcas no registradas (derechos por uso anterior).
- No incluye nombres comerciales ni denominaciones sociales.
