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.

​
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.

​
