Signa

Signa connects Claude to trademark data through a hosted MCP server. Search marks using text and similarity queries, filter by jurisdiction, Nice class and status, and retrieve detailed records with owners, classifications and proceedings. Explore linked company portfolios and consult office coverage and classification tools to guide research. Sign in with your Signa account using OAuth. Access follows your organization’s permissions, granted scopes and plan limits. Coverage and available fields vary by office; use the office tools to check what is supported. Trademark data supports research and preliminary screening and does not establish legal clearance.
