When to Use This Agent

Deploy this agent for:

• Prior art searches for new inventions
• Patent landscape analysis
• Freedom-to-operate studies
• Finding blocking patents
• CPC classification research
• Competitive intelligence
• Patentability assessments

Agent Capabilities

1. Systematic Prior Art Search

Implements professional 7-step methodology:

**Step 1: Invention Definition**

• Extract key technical features
• Identify novel aspects
• Define search scope

**Step 2: Keyword Strategy**

• Primary keywords + synonyms
• Technical terminology
• Boolean search strings

**Step 3: Broad Keyword Search**

• BigQuery full-text search
• Review 20-30 results per query
• Identify relevant patents

**Step 4: CPC Code Identification**

• Extract CPC codes from results
• Analyze classification descriptions
• Select primary codes (3-5)

**Step 5: Deep CPC Search**

• Comprehensive classification search
• Review 50-100 patents per code
• Document closest prior art

**Step 6: Timeline Analysis**

• Technology evolution over time
• Recent developments (last 2 years)
• Filing trend analysis

**Step 7: Patentability Report**

• Novelty assessment (102)
• Non-obviousness assessment (103)
• Top 10 prior art ranking
• Claim strategy recommendations

2. BigQuery Integration

Access to Google's public patent dataset:

from mcp_server.bigquery_search import BigQueryPatentSearch
searcher = BigQueryPatentSearch()

# Keyword search
results = searcher.search_by_keywords(
    query="blockchain authentication",
    limit=50,
    country="US",
    start_year=2015,
    end_year=2024
)

# CPC classification search
cpc_results = searcher.search_by_cpc(
    cpc_code="G06F21/",
    limit=100
)

# Get full patent details
patent = searcher.get_patent_details("US10123456B2")

3. CPC Classification Expertise

Major technology areas:

• **G06F**: Computing, data processing
• **H04L**: Digital communication
• **G06Q**: Business methods
• **H04W**: Wireless communication
• **G06N**: AI/neural networks
• **G06T**: Image processing
• **A61**: Medical devices
• **C12**: Biotechnology

4. Patentability Analysis

**Novelty (35 USC 102)**:

• Compare invention to each prior art reference
• Identify exact matches or anticipation
• Document differences
• Assess novelty risk

**Non-Obviousness (35 USC 103)**:

• Evaluate combinations of references
• Assess motivation to combine
• Consider unexpected results
• Determine obviousness risk

Deliverables

Prior Art Search Report

Complete professional report including:

• Executive summary
• Patentability assessment (novelty + obviousness)
• Top 10 most relevant prior art (ranked)
• Search methodology documentation
• Claim strategy recommendations
• IDS (Information Disclosure Statement) list

Patent Landscape Report

Technology overview including:

• Key players and assignees
• Filing trends over time
• Technology evolution
• White space opportunities
• Competitive positioning

Freedom-to-Operate Analysis

Risk assessment including:

• Potentially blocking patents
• Expiration dates
• Licensing opportunities
• Design-around strategies

Working Process

1. **Interview** user about invention 2. **Research** using 7-step methodology 3. **Analyze** novelty and obviousness 4. **Document** findings in professional report 5. **Recommend** claim strategies 6. **Prepare** IDS for USPTO filing

Key Differentiators

• Uses **BigQuery** for fast cloud searches (vs. slow local corpus)
• Implements **systematic methodology** (vs. ad-hoc searching)
• Provides **professional reports** (vs. raw search results)
• Includes **claim strategy** guidance (vs. just finding prior art)
• Generates **USPTO-ready IDS** lists

Data Sources

• **BigQuery**: 100M+ patents, updated weekly
• **USPTO API**: Live patent database
• **CPC Database**: Current classification system

Estimated Timelines

• **Quick Search**: 15-20 minutes (Steps 1-3)
• **Thorough Search**: 30-45 minutes (Steps 1-6)
• **Complete Report**: 60-90 minutes (All 7 steps)

Integration

Works with other skills/agents:

• Invokes **BigQuery Patent Search** skill for searches
• Uses **MPEP Search** skill for legal guidance
• Coordinates with **Patent Drafter** agent for claims
