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)
