USPTO 특허 심사과정 분석 CLI — 문서 다운로드 · XML 파싱 · MD 생성

uspto-oa-cli

A CLI tool that downloads USPTO patent prosecution documents via the ODP (Open Data Portal) API, parses the XML, and converts them into structured Markdown.

Supports a workflow where the generated MD file is passed to AI agents (Claude Code, Gemini CLI, etc.) for prosecution strategy analysis.

Requirements

• Python 3.12+
• uv
• USPTO API key (issued via the ODP portal)

Installation

# pip
pip install uspto-oa-cli

# uv (global install)
uv tool install uspto-oa-cli

# uv (add as project dependency)
uv add uspto-oa-cli

# local development
uv sync

API Key Setup

# Interactive setup (recommended) — saved to ~/.oa-cli.toml
# Prompts for: API key, HTTPS/HTTP proxy URL, CA bundle path
uspto-oa configure

# Show current configuration
uspto-oa configure --show

Or set via environment variable:

export USPTO_API_KEY=your_api_key_here

Proxy & SSL (Corporate Networks)

If you're behind a corporate proxy or need a custom CA bundle, set them during configure or edit ~/.oa-cli.toml directly:

[auth]
api_key = "YOUR_KEY"

[proxy]
https = "http://proxy.example.com:8080"
http  = "http://proxy.example.com:8080"

[ssl]
ca_bundle = "/path/to/corporate-ca.pem"

These settings are applied to all HTTP requests. If omitted, the standard requests library environment-variable fallback (HTTPS_PROXY, HTTP_PROXY, REQUESTS_CA_BUNDLE) applies.

Usage

# 0. Check document list before downloading
uspto-oa list 16330077

# 1. Download documents (saved to file/{app_num}/)
uspto-oa download 16330077

# 2. Parse XML → generate prosecution.md
uspto-oa extract 16330077
# Output: file/16330077/16330077_prosecution.md

# Extract in JSON format
uspto-oa extract 16330077 --format json

# 3. (Optional) OCR image-based PDFs → searchable PDFs
uspto-oa ocr 16330077

# 4. (Optional) Embed OCR text into prosecution.md for AI analysis
#    Run after step 3. Selectively include high-value doc codes to
#    avoid filling up the AI context window.
uspto-oa extract 16330077 --with-ocr --ocr-codes CTNF,CTFR,REM,EXIN,CTAV

# Download specific document codes only
uspto-oa download 16330077 --doc-codes CTNF,CTFR,NOA

# Force re-download (overwrite existing files)
uspto-oa download 16330077 --force

# Verbose logging
uspto-oa -v download 16330077

# One-time API key override
uspto-oa download 16330077 --api-key YOUR_KEY

Command Options

uspto-oa list <application>

Option	Description
--all	Show all documents without prosecution-related filter
--format [table|json]	Output format (default: table)
--api-key TEXT	API key

uspto-oa download <application>

Option	Description
--doc-codes CODES	Comma-separated document codes (e.g. CTNF,CTFR,NOA). All prosecution docs if omitted
--output-dir DIR	Save path (default: file/{app_num}/)
--force	Re-download even if file already exists
--api-key TEXT	API key (overrides config file and environment variable)

uspto-oa extract <application>

Option	Description
--format [md|json]	Output format (default: md)
--output-dir DIR	File directory (default: file/{app_num}/)
--with-ocr	Embed OCR text from *_ocr.pdf files into prosecution.md (run ocr first)
--ocr-codes CODES	Comma-separated doc codes to embed (default: CTNF,CTFR,NOA,NACT,EXIN,REM,CTAV + A*)

Doc code guide for --ocr-codes — choosing the right codes prevents AI context overflow:

Code	Description	OCR value	Default included
CTNF	Non-Final Office Action	High — core rejection grounds	✓
CTFR	Final Office Action	High — core rejection grounds	✓
NOA / NACT	Notice of Allowance	Medium — allowance reasons	✓
EXIN	Examiner Interview Summary	High — often PDF-only in modern apps	✓
REM	Remarks (applicant arguments)	High — often PDF-only	✓
CTAV	Advisory Action	Medium — examiner's response to after-final amendment	✓
A*	All Amendment variants	High — when XML parsing fails	✓
ABN	Abandonment	Low	—
RCE / RCEX	Request for Continued Examination	Low	—
SRNT / SRFW	Search Report	Low — very long, little analysis value	—
892 / 1449 / IDS	Prior Art / IDS	Low — very long, reference lists	—

uspto-oa ocr <application> (requires pip install ocrmypdf)

USPTO PDF documents are full-page image scans — standard text extraction fails. This command runs OCR on every PDF in the application directory and produces searchable PDFs alongside the originals.

Option	Description
--force	Re-OCR even if output already exists
--in-place	Overwrite original PDFs instead of creating *_ocr.pdf copies
--no-deskew	Skip deskew correction (faster)
--output-dir DIR	File directory (default: file/{app_num}/)

# Install OCR dependency
pip install ocrmypdf
# or: uv pip install ocrmypdf
# or: pip install uspto-oa-cli[ocr]

# Run OCR (creates {original}_ocr.pdf next to each PDF)
uspto-oa ocr 16330077

# Overwrite originals in place
uspto-oa ocr 16330077 --in-place

Workflow

uspto-oa list {app_num}               # Check document list before downloading
    └─ Browse prosecution document codes and formats

uspto-oa download {app_num}
    └─ Save XML / PDF to file/{app_num}/

uspto-oa extract {app_num}            # XML-only (fast, default)
    └─ Generate file/{app_num}/{app_num}_prosecution.md
         └─ AI agent (Claude Code / Gemini CLI)
              └─ Prosecution strategy analysis, summaries, Q&A

# ── Optional: include PDF-only documents in prosecution.md ──────────────────

uspto-oa ocr {app_num}                # Step A: OCR all PDFs → *_ocr.pdf
    └─ Generate {original}_ocr.pdf next to each PDF

uspto-oa extract {app_num} \          # Step B: embed selected OCR text
    --with-ocr \
    --ocr-codes CTNF,CTFR,REM,EXIN,CTAV
    └─ prosecution.md now includes full text of selected PDF documents
         └─ AI agent reads one file, gets complete prosecution history
