AI-powered Chinese patent disclosure drafting tool

Patent Drafting Assistant

专利撰写助手 — AI-powered patent disclosure drafting

Features • Quick Start • Usage • Structure • Customize • Contributing

---

Input your core technical concept and let AI generate a complete 10-chapter Chinese patent disclosure. Supports streaming generation, per-chapter editing, auto figure prompts, version history, and DOCX/Markdown export — all through a clean local web UI.

Features

• AI-driven drafting — Generate a complete patent disclosure from a single technical concept
• 10-chapter standard structure — Follows Chinese patent disclosure conventions
• Concept-first workflow — Analyze your concept first, then generate chapters based on structured extraction
• Technical feature analysis — AI extracts key elements, innovation points, and expected effects
• Streaming generation — Watch each chapter generate in real time via SSE
• Per-chapter editing — Edit any chapter manually, switch between Markdown edit and preview modes
• Auto figure prompts — AI inserts [Figure N: description] markers; right panel shows the figure checklist
• Version history — Every save creates a snapshot; rollback anytime
• DOCX export — Professional Word documents with correct Chinese fonts (Song Ti / Hei Ti)
• Markdown export — Plain text for other editing tools
• Zero-config LLM — Auto-reads API keys from Claude Code settings or environment variables

Quick Start

Prerequisites

• Python 3.10+
• An Anthropic-compatible LLM API (e.g. DeepSeek, OpenAI, Claude)

Install

git clone https://github.com/Dyp130/Patent-assistant.git
cd Patent-assistant
pip install -r requirements.txt

Configure

Copy the example env file and set your credentials:

cp .env.example .env
# Edit .env with your API key, base URL, and model

Or export as environment variables:

export ANTHROPIC_BASE_URL="https://api.deepseek.com"
export ANTHROPIC_AUTH_TOKEN="your-api-key"
export ANTHROPIC_MODEL="deepseek-chat"

If you have Claude Code installed, the app automatically reads API config from ~/.claude/settings.json.

Launch

python run.py

Open http://127.0.0.1:8000

Usage

Workflow

Step	Action
1	Click New Patent Draft, choose patent type, and enter your core technical concept
2	Click Save Concept, then optionally Analyze Technical Features
3	Click Generate All (or select individual chapters via AI Generate)
4	Review, edit, and preview each chapter
5	Export as DOCX or Markdown

Screenshots

Screenshots coming soon — run python run.py to see it in action.
