Agent Capabilities

1. Hybrid Search System

**Technology Stack**:

**Search Process**:

from mcp_server.mpep_search import MPEPIndex

mpep_index = MPEPIndex()
mpep_index.build_index()  # loads the on-disk index

results = mpep_index.search(
    query="claim definiteness requirements",
    top_k=5,
    source_filter="MPEP",  # or "35_USC", "37_CFR", "SUBSEQUENT"
    is_statute=None,
    is_regulation=None,
    is_update=None

Research Methodology

Step 1: Query Formulation

**For Concepts** (use semantic search):

• "claim definiteness requirements"
• "enablement written description difference"
• "abstract subject matter guidance"

**For Specific Citations** (use keyword search):

• "35 USC 112(b)"
• "MPEP 2163"
• "37 CFR 1.72"

**For Procedures** (use natural language):

• "how to respond to 112(b) rejection"
• "requirements for abstract length"
• "when is best mode required"

Step 2: Search Execution

# Broad conceptual search
results = mpep_index.search(
    "claim definiteness requirements",
    top_k=10
)

# Filtered search (statutes only)
statute_results = mpep_index.search(
    "written description enablement",
    top_k=5,
    is_statute=True
)

# Section-specific retrieval
section_chunks = mpep_index.get_section("2163")  # MPEP 2163

Step 3: Result Analysis

Each result contains:

• **Score**: Relevance (0.0-1.0)
• **Text**: Full content of chunk
• **Section**: MPEP section number or statute citation
• **Page**: Page numbers in source document
• **Source**: MPEP, 35_USC, 37_CFR, or SUBSEQUENT
• **Metadata**: Statute/regulation flags, update dates

Step 4: Citation Formatting

**MPEP Citations**:

• "MPEP § 2163" (section symbol)
• "MPEP 2163.02" (subsection)
• "MPEP 2163.03(b)" (sub-subsection)

**Statute Citations**:

• "35 U.S.C. § 112(b)" (official format)
• "35 USC 112(b)" (common format)

**Regulation Citations**:

• "37 C.F.R. § 1.72" (official format)
• "37 CFR 1.72" (common format)
