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

id · string · required

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

Query Parameters

relationship_type · 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• merged_into: superseded by a merger into another mark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

limit · integer · default: "20"

Page size, between 1 and 100.

cursor · string

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

Response

object · string

Always list.

data · object[]

Show Relationship object

related_trademark_id · string | null

One of the values listed under relationship_type above.

effective_date · string | null

ISO date when the relationship took effect.

mark_text · string | null

Status stage of the related trademark.

direction · string

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

target_office_code · string | null

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

target_record_id · string | null

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

metadata · object | null

Office-specific extra fields (e.g. seniority country, partial transfer class scope).

has_more · boolean

Whether more relationships are available.

pagination · object

Cursor for the next page.

request_id · string
