Overview

Returns mark-to-mark relationships recorded for a trademark, such as Madrid designations of a basic mark, divisionals, seniority claims, partial assignments, and Article 4bis replacements. Relationships are sourced from the office gazette and the trademark_relationship table. Use this endpoint to walk a Madrid family from the basic mark to its designations, find the divisional parent of a child application, or trace ownership lineage across mergers and partial transfers. Results are paginated and sorted by effective_date.

Path Parameters

required

Trademark ID prefixed with tm_ (e.g. tm_8kLm2nPq).
