Subject: [PATCH] refactor: remove duplicate patent_api.py module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removed SPARC/patent_api.py as it contained duplicate implementations
of parse_patent_pdf, extract_section, and clean_patent_text functions
that are already present in SPARC/serp_api.py as static methods.

The serp_api.py implementation is actively used in main.py, while
patent_api.py was unused legacy code.
