How to track federal court cases involving a specific company

Step-by-step guide to looking up federal court dockets (CourtListener data) by company, by Nature of Suit code, or by specific docket ID — with canonical per-case detail pages.

Steps

1. Find all cases where a company is a party

   By party: /api/v1/courts/by-party/{company_name}. Returns case name, court ID, date filed, Nature of Suit code, and assigned judge.

2. Filter by case type using Nature of Suit (NOS) code

   Filter by Federal Judicial Center NOS code:

   • ?nos=850 — Securities/Commodities
   • ?nos=830 — Patent
   • ?nos=410 — Antitrust
   • ?nos=365 — Personal Injury: Product Liability
   • ?nos=367 — Personal Injury: Health Care/Pharma
   • ?nos=480 — Consumer Credit

3. Drill into a specific case by docket ID

   Per-case canonical: /case/{docket_id} — docket number, court, NOS, cause, judge, parties, CourtListener source URL. HTML + .md + .json (schema.org/Legislation).

4. Watch for new high-signal filings via /today

   /today includes a "🏛️ Federal court filings — high-signal NOS codes" section bounded by the response's UTC source-date window. Source freshness is reported separately at /api/v1/freshness.
