What I want to do with the data is largely irrelevant; I care more about being free to analyze this data--data that belongs to the public.

But to answer your question more precisely, I'm interested in identifying trends in the courts with respect to litigated issues. It'd be interesting to determine whether certain pre-trial motions have a higher propensity to be granted/denied in a particular court, before a particular judge, etc. Additionally, I'm interested in tracking cases on which attorneys and law firms typically rely when writing their briefs or other documents submitted to the court.
