Training Data

• 30,000 silver-labelled patent claims (Y02 CPC codes)
• 100 gold-labelled claims (human verified via HITL)
• Total: 30,100 training examples — perfectly balanced 50/50

Pipeline Overview

This model is the final step in a 4-stage pipeline:

1. QLoRA Fine-Tuning — Mistral-7B fine-tuned as Y02 domain expert Judge
2. 3-Agent MAS — Advocate / Skeptic / Judge debate on 100 uncertain claims
3. HITL Review — Human reviewed only 11 flagged uncertain claims
4. PatentSBERTa Fine-Tuning — Final classifier trained on 30,100 examples
