Have you been hearing all the buzz about legal analytics on Westlaw Edge and Lexis Advance? Don't forget that you also have access to legal analytics platform Lex Machina!

Lex Machina , a LexisNexis research tool, provides litigation and business data for legal professionals. The tool harvests data from a variety of resources to enable users to identify meaningful patterns that aid in the practice of law. Sources include PACER, the U.S. Patent and Trademark Office, the International Trade Commission, and other primary docket-based sources.

Practitioners can use Lex Machina to gain important information about judges, opposing counsel, parties, and cases (for instance, biographical information, rulings and damages awarded statistics, case type statistics, etc.). Lex Machina was started by legal and technology experts at Stanford Law School and Stanford’s Computer Science department. Their homepage explains their mission for legal professionals as follows:

“For the first time, lawyers can combine insights gleaned from bottom-up data with traditional top-down controlling authority found in statutes, rules, and court opinions. It’s new, it’s unorthodox and it’s extremely valuable. But Legal Analytics also brings lawyering back to its roots It provides lawyers with facts on which to base opinions – the core element of good lawyering. Objective data replaces subjective anec-data.”

Students can benefit from the information provided by Lex Machina in a few important ways. First, you may want to track the way a renowned judge has ruled over the years to understand his or her judicial motivations and philosophy. Second, you may have a writing-intensive course and are assigned a paper on a particular case. You could use Lex Machina data about the attorneys and judges to show a trend in arguments and rulings to predict an upcoming outcome in a higher court. Finally, you may have a transition-to-practice course in which you are to consider your strategy for a hypothetical issue and client. You could consult Lex Machina's analytics to prepare your approach. It could be useful to know how many trademark cases the presiding judge has heard over his or her career, for example. 

Lex Machina began as a data tool focused on intellectual property law, but the scope has been expanded in recent years. Data is now available about anti-trust, bankruptcy, employment, product liability, and securities cases.
