EPC/PCT Legal Search Skill

Hybrid RAG search across the European Patent Convention (EPC), EPO Guidelines for Examination, and PCT Rules for patent law research.

When to Use

Invoke this skill when users ask to:

• Find EPC articles or rules on a specific topic
• Search EPO Guidelines for Examination
• Look up PCT rules or Administrative Instructions
• Compare EPC requirements with USPTO/MPEP practice
• Research EPO Board of Appeal case law principles
• Understand European patent prosecution procedure
• Find legal basis for EPO examination objections

What This Skill Does

Provides legal research across European and international patent law:

1. **EPC Search** (European Patent Convention):

• Articles 1-178 EPC
• Rules 1-167 EPC (Implementing Regulations)
• Protocol on Interpretation of Art. 69 EPC
• Protocol on Centralisation
• Protocol on Privileges and Immunities

2. **EPO Guidelines Search** (Guidelines for Examination):

• Part A: Guidelines for Formalities Examination
• Part B: Guidelines for Search
• Part C: Guidelines for Procedural Aspects of Substantive Examination
• Part D: Guidelines for Opposition and Limitation/Revocation
• Part E: Guidelines for General Procedural Matters
• Part F: Guidelines for Substantive Examination (The Patent Application)
• Part G: Guidelines for Patentability
• Part H: Guidelines for Amendments and Corrections

3. **PCT Rules Search** (Patent Cooperation Treaty):

• PCT Articles 1-69
• PCT Rules 1-96 (Regulations under the PCT)
• Administrative Instructions under the PCT
• WIPO Standards (ST.25, ST.26, ST.36)

4. **Cross-Jurisdiction Comparison**:

• EPC vs 35 USC mapping
• EPO Guidelines vs MPEP equivalents
• PCT requirements vs national requirements

Required Data

**MCP Tools Available**:

• `search_patent_law` - Search EPC, EPO Guidelines, PCT rules with jurisdiction parameter
• `search_mpep` - Search MPEP/35 USC/37 CFR for comparison

How to Use

When this skill is invoked:

1. **Determine jurisdiction**:

• EPO: search EPC articles/rules and EPO Guidelines
• PCT: search PCT articles/rules and Administrative Instructions
• Both: search across all sources
• Comparison: search EPO + USPTO sources

2. **Execute search**:

**EPC/EPO Guidelines search**:

   results = search_patent_law(
       query="claim clarity requirements",
       jurisdiction="EPO",
       top_k=5
   )

**PCT rules search**:

   results = search_patent_law(
       query="unity of invention",
       jurisdiction="PCT",
       top_k=5
   )

**Cross-jurisdiction comparison**:

   epo_results = search_patent_law(query="sufficiency of disclosure", jurisdiction="EPO")
   us_results = search_mpep(query="enablement requirement")

3. **Present results**:

• Show relevant provisions with full text
• Provide article/rule numbers and section references
• Include EPO Guidelines commentary
• Note practical implications for prosecution
