About
Junior JR3 is an AI-centric legal document platform built for drafting, reviewing, researching, and completing legal work directly inside Microsoft Word and Google Docs. Its document library provides purpose-built workflows, playbooks, skills, sequences, and rules for legal document types across multiple practice areas, allowing firms to apply their own standards, prior work, and drafting style. AI repositories, prompt libraries, agents, writing styles, and training datasets sit above the underlying models, so teams can use OpenAI, Anthropic, Google Gemini, or privately deployed models and switch between them without rebuilding workflows. For patent and trademark work, JR3 connects directly to live USPTO, WIPO, EPO, federal case law, and state case law data. Its tools support Office Action responses, examiner-focused drafting, patent searching, claim charting, appeal briefs, opinion letters, legal memoranda, assignments, NDAs, and other documents.

About
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.
