mpep-search

MPEP search retrieves relevant sections from the Manual of Patent Examining Procedure, 35 USC statutes, and 37 CFR regulations using hybrid RAG search combining vector and keyword matching. You can filter results by source type and get full section text with relevance scores and page references.

Yes, the search supports source filtering via the source_filter parameter to retrieve results specifically from MPEP, 35 USC, 37 CFR, or recent updates. You can also use boolean flags is_statute, is_regulation, and is_update to narrow results.

This tool uses hybrid RAG search combining vector embeddings via FAISS, BM25 keyword matching, and HyDE query expansion, followed by cross-encoder reranking. This multi-stage approach returns the most relevant matches across all sources with structured metadata including rank, relevance score, and section details.

You can request full section retrieval by specifying the MPEP section number. The search returns complete text content along with file location, page number, and source classification for that specific section.

The search enforces input validation and caps the top_k parameter at 20 results maximum. The system uses a lazy-loaded singleton index for efficient retrieval and returns structured output including rank, source metadata, relevance scores, and matched text.
