GENESIS PATENT VECTORIZER
==========================
Deep integration of all 9 patents into AIVA's semantic memory.

Features:
    - Extracts content from patent PDFs and knowledge graphs
    - Generates embeddings for semantic search
    - Stores in Qdrant vector database
    - Creates cross-patent relationship graph
    - Enables patent-aware validation

Usage:
    vectorizer = PatentVectorizer()
