Signa normalizes trademark data from international offices into a consistent format. 3 offices are in production today (USPTO, EUIPO, WIPO) with 18 more planned. Every trademark record includes core identity fields, classifications, owners, events, and more.

​
Response Tiers

To optimize payload size, Signa returns trademark data at three detail levels:
TierUse CaseFields
CompactList views, autocompleteID, mark text, status stage, filing date
SummarySearch results, portfolio viewsCompact + owner, Nice classes, jurisdiction
DetailFull record viewEverything: events, media, attorneys, deadlines
The tier is fixed per endpoint — for example, GET /v1/trademarks/{id} always returns detail, while list and search endpoints return summary: 
GET /v1/trademarks/tm_abc123       # detail tier
GET /v1/trademarks                 # summary tier
POST /v1/trademarks/search         # summary tier

​
Trademark Lifecycle

A trademark moves through these status stages: 
filed -> examined -> published -> registered -> renewed -> expired
                 \-> opposed -> cancelled
                 \-> abandoned
The status.primary field indicates the high-level state (active, pending, or inactive), while status.stage reflects the current canonical lifecycle stage.

​
