About Signa
Signa is a cloud-based trademark data API and web research tool for developers, trademark professionals, law firms, in-house legal and brand teams, and legal technology providers. It lets users search and retrieve records from the registers Signa currently covers, with normalized fields for mark text, status, owners, classes and filing dates. Search tools support exact, fuzzy and phonetic matching, and results can be queried across supported offices through a consistent interface. Developers can use the REST API, TypeScript SDK and hosted Model Context Protocol server to build trademark lookups into applications and AI workflows. The service also provides portfolio and deadline data, while monitoring watches, alerts, and some screening capabilities are listed as beta. A free API tier is available, with paid plans based on monthly credits.
