| `search_by_assignee` | Find all patents owned by a company or organization |
| `get_patent_citations` | Citation networks with impact scoring |
| `analyze_technology_trends` | Patent filing trends over time with growth rates |
| `search_by_cpc` | Search by CPC classification code (e.g. G06N for AI/ML) |
| `search_recent_patents` | Find newest patents with optional category filter (pharma, AI, etc.) |
| `compare_portfolios` | Head-to-head comparison of two companies' patent portfolios |
| `get_patent_landscape` | Technology landscape: trends, top players, CPC + geographic distribution |
| `search_by_classification` | Search by IPC/CPC code at subgroup level for precise research |
| `get_patent_family` | Find related patents (continuations, divisionals) in the same family |
| `get_top_patent_holders` | Ranking of companies by patent count, filterable by sector |
| `analyze_patent_landscape` | Strategic landscape analysis with insights and recommendations |
| `get_patent_claims` | Extract patent claims (the legally binding part) |

### What's New in v0.3.0

## Installation

```bash
pip install patent-intelligence-mcp-server
```

## Quick Start

### Claude Desktop

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "patents": {
      "command": "patent-server"
    }
  }
}
```

### Claude Code CLI

```bash
claude mcp add patents -- patent-server
```

### Direct Usage

```bash
patent-server
```

## Example Queries

Once connected, your AI agent can answer questions like:

**Basic Search:**
- "Search for recent patents about quantum computing"
- "Show me details for patent US-11234567"
- "What patents has Elon Musk filed?"
- "Find all Tesla patents"

**Advanced Analysis:**
- "Compare Apple's and Samsung's patent portfolios over 5 years"
- "Show me the technology landscape for solid state batteries"
- "Find patents in CPC class G06N (machine learning)"
- "Show the newest patents about mRNA vaccines from the last 6 months"
- "Analyze patent trends in CRISPR technology over 10 years"
- "How does Google's patent portfolio compare to Microsoft's?"

**New in v0.3.0:**
- "Search patents in IPC classification H04L9/32 (cryptographic authentication)"
- "Find the patent family for patent 11234567"
- "Who are the top patent holders in the pharma sector?"
- "Give me a strategic landscape analysis for quantum computing"
- "Extract the claims for patent 11234567"
- "Show me recent AI patents from the last 30 days"

## CPC Classification Codes

Common codes for the `search_by_cpc` tool:

| Code | Area |
|------|------|
| `G06N` | Machine Learning / AI |
| `G06F` | Digital Data Processing |
| `H01L` | Semiconductor Devices |
| `H04` | Telecommunications |
| `A61K` | Pharmaceuticals |
| `C12N` | Biotechnology |
| `B60` | Vehicles |
| `F03D` | Wind Turbines |

## API Source

**USPTO PatentsView API** — Free, no API key required. Covers all US patents with full metadata, inventors, assignees, citations, and CPC classifications.

## Configuration

Optional environment variables:

| Variable | Default | Description |
|----------|---------|-------------|
| `PATENT_HTTP_TIMEOUT` | `30` | HTTP request timeout in seconds |
| `PATENT_DEFAULT_LIMIT` | `10` | Default number of results |
| `PATENT_MAX_LIMIT` | `50` | Maximum results per query |
| `PATENT_CACHE_ENABLED` | `true` | Enable/disable response caching |
| `PATENT_CACHE_TTL` | `600` | Cache time-to-live in seconds |

## Performance

- **Parallel requests**: Patent details fetch 4 data sources simultaneously instead of sequentially
- **Trend analysis**: Year-by-year queries run in parallel (5-year analysis: ~1 request time instead of ~5)
- **Landscape analysis**: 5 parallel API calls for comprehensive results in a single request cycle
- **In-memory caching**: Repeated queries return from cache (256 entries, 10-minute TTL)
- **Patent families**: Parallel citation + base patent lookups
