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 office gazette references and Signa’s own mark-to-mark linking. 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

string

required

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

Query Parameters

string

Filter by a single relationship type. Omit to return every relationship for the mark. Valid values:

madrid_designation_of: this mark is a national designation of a Madrid IR basic mark
based_on_basic_application: Madrid IR built on a pending application
based_on_basic_registration: Madrid IR built on a registered mark
seniority_claim: EU mark claiming seniority from an earlier national right
divisional_parent: original application that this mark was divided from
partial_assignment_from: created by a partial assignment of an earlier mark
merged_into: superseded by a merger into another mark
transformed_from: Madrid transformation from a ceased IR
replaces_under_4bis: replaces an earlier national mark under Madrid Article 4bis
partial_transfer_of: partial transfer source mark
continuation_of: continuation of an earlier mark across re-filings

integer

default:"20"

Page size, between 1 and 100.

string

Opaque cursor returned in the previous response’s pagination.cursor.

Response

string | null

ISO date when the relationship took effect.

string | null

Mark text of the related trademark when known.

Either outgoing (this mark relates to another) or incoming (another mark relates to this one).

string | null

Office code reported by the source data when the related mark is not yet ingested.

string | null

Office-native record number reported by the source data when the related mark is not yet ingested.

object | null

boolean

Whether more relationships are available.

object

Cursor for the next page.

string

Unique request identifier for support and debugging.
