Removal Evidence Search — Outputs

Purpose: Look for evidence that Litman's name was removed from the correspondence block, and check who is currently listed as attorney of record.

Run the Script

export USPTO_API_KEY='your_key'
python scripts/search_removal_evidence.py

Optional: USPTO_ODP_API_KEY or PATENT_CLIENT_ODP_API_KEY for attorney endpoint (falls back to USPTO_API_KEY).

File	Purpose
`CHANGE_OF_CORRESPONDENCE_SEARCH.csv`	Step 1: For each application, whether a Change of Correspondence Address document exists in the IFW
`ATTORNEY_OF_RECORD_SEARCH.csv`	Step 2: For each application, who is currently listed as attorney of record (ODP API)

cca_found = YES → A Change of Correspondence document was filed; review cca_details for dates. Could indicate removal (or other address change).
litman_in_api = NO (but Litman on Line 74 of issued patent) → Suggests Litman may have been removed from attorney-of-record after issuance, or API returns different data than printed patent.
litman_in_api = YES → Litman still listed in attorney API for that application.
