PatentPath — Agentic RAG for USPTO Briefings (Starter)

This is a small, runnable demo that:

• Ingests a sample patent dataset (CSV)
• Builds a hybrid retrieval index (BM25 + vectors via Chroma + Sentence Transformers)
• Generates a cited brief with inline [doc_id] references
• Shows a Streamlit UI to test queries

Quick Start

# 1) Create and activate a virtual environment
python -m venv .venv
# Windows:
.venv\Scripts\activate
# macOS/Linux:
source .venv/bin/activate

# 2) Install dependencies
pip install --upgrade pip
pip install -r requirements.txt

# 3) Build the index (uses sample CSV in data/raw)
python -m src.ingest

# 4) Run the demo UI
streamlit run app/streamlit_app.py

Try these sample queries

• LLM watermarking methods
• drone swarming computer vision
• synthetic data generation patents
• transformer optimization energy efficiency

Notes

• If nltk complains about missing data, the code has a fallback sentence splitter (no internet required).
• If chromadb install is problematic on your system, try updating pip and setuptools: pip install --upgrade pip setuptools wheel.

Security: This starter uses public, synthetic sample data. Do not ingest client or restricted data.
