aid: lex-machina name: Lex Machina description: >- Lex Machina is a legal analytics platform owned by LexisNexis that transforms raw court documents and dockets into structured datasets so litigators, corporate legal teams, insurers, and judges can make data-driven decisions about cases, courts, judges, lawyers, parties, and damages. The platform covers all 94 federal district courts, the 13 federal courts of appeals, the PTAB, the ITC, bankruptcy courts, and a growing list of state courts (with 18M+ additional state cases for party analytics), and tracks 8,000+ judges, 6,000+ expert witnesses, 146M+ counsel mentions, and 149M+ party mentions across 10M+ cases and 45M+ documents. Lex Machina exposes its Legal Analytics through a public Litigation Analytics API (OAuth 2.0, JWT bearer tokens) at api.lexmachina.com with synchronous Python and Node.js client libraries plus an A2A (Agent-to-Agent) agent for AI/agent integrations. Practice area coverage includes Antitrust, Bankruptcy, Commercial, Consumer Protection, Contracts, Copyright, Employment, ERISA, Insurance, Patent, Product Liability, Securities, Tax, Torts, and Trademark litigation.
