Lex Machina is a legal analytics company (acquired by LexisNexis in 2015) that uses machine learning to analyse federal court case data — docket entries, rulings, damages, timelines — and extract structured intelligence about litigation patterns that is impractical to analyse manually across millions of cases.
Judge analytics is the most used capability — analysing a specific federal judge's historical decisions in patent, IP, employment, or antitrust cases to understand their typical timelines, how often they grant motions, which arguments they favour, and their damages awards patterns. For trial lawyers preparing for a specific judge, this intelligence informs case strategy in ways that were previously only available through years of personal experience.
Opposing counsel analytics shows how specific law firms and attorneys have performed in comparable cases — win/loss rates, settlement tendencies, argument strategies, and average case timelines. For law firms evaluating potential opposing counsel or preparing for known adversaries, this intelligence supports more informed litigation decisions.
Damages analytics provides statistical data on actual damages awarded in comparable cases across industries, legal theories, and court districts — informing case valuation and settlement positioning with empirical data rather than anecdote.
Lex Machina covers patent, IP, employment, commercial, antitrust, and securities litigation in federal courts, with coverage expanding over time. Its acquisition by LexisNexis has integrated it with LexisNexis's broader legal research ecosystem.
Lex Machina runs as document analysis llm software built around text and data workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web.
