# get_owner_related_parties Find entities likely related to a trademark owner (predecessors, subsidiaries, sister companies) from USPTO evidence: shared ownership history on the same marks, shared filing addresses (agent addresses excluded), and shared distinctive name tokens. Returns evidence and a high/possible confidence tier per hit — treat 'possible' as tentative. Use when analyzing an owner's full corporate family, portfolio scope, or whether two owners of similar marks are actually affiliated. Pass the owner name exactly as recorded (resolve with resolve_trademark_subject first if ambiguous). Agent View of the PolicyLayer registry record for `get_owner_related_parties`.
