Epc Search

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:

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

   PCT rules search:

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

   Cross-jurisdiction comparison:

   pythonCopy code
   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

EPC/EPO LEGAL RESEARCH RESULTS
=================================

Query: "claim clarity requirements"
Jurisdiction: EPO (EPC + Guidelines)

[1] Art. 84 EPC - The Claims
    "The claims shall define the matter for which protection
    is sought. They shall be clear, concise and be supported
    by the description."

    EPO Guidelines F-IV, 4 - Clarity
    "Each claim should be read giving the words the meaning
    and scope which they normally have in the relevant art..."

    Key Points:
    - Claims must be clear on their own (not by reference to spec)
    - Technical terms given their normal meaning in the art
    - Relative terms need objective reference point
    - Functional features must be verifiable

[2] Rule 43(1) EPC - Form and content of claims
    "...shall contain: (a) a statement indicating the designation
    of the subject-matter and those technical features necessary
    for the definition... (preamble); and (b) a characterising
    portion preceded by 'characterised in that'..."

    EPO Guidelines F-IV, 3.2 - Two-part form
    "Independent claims should normally be in the two-part form..."

Related MPEP Comparison:
- MPEP 2173: Claims Must Particularly Point Out and Distinctly Claim
- 35 USC 112(b): Equivalent US clarity requirement
- Key difference: EPO applies stricter objective clarity standard
