How to Get Court Records and Trademark Data in Bulk

Court decisions and IP registrations are public records with terrible bulk access — per-document viewers, session-bound searches, and PDFs. This guide covers structured exports from eight court-records sources and three trademark/patent registries across the US, EU, Brazil, India, and China.

US case law: CourtListener and Google Scholar

The CourtListener scraper exports opinions from the largest open US case-law archive — search by court, date, or query and get structured opinion records with citations. The Google Scholar case law scraper covers the same ground from the discovery side: its ranking surfaces the cases practitioners actually cite.

US state courts: Oklahoma, Arkansas, Louisiana dockets

State-court records live in per-state systems with per-state quirks. The state court records scraper covers OSCN (Oklahoma), Arkansas CourtConnect, and Louisiana's 1st JDC — docket searches by party name in bulk, the raw material for litigation-history checks and judgment research.

Brazil court records from JusBrasil

The JusBrasil scraper searches Brazil's dominant legal platform by party or case number and returns case records and publications. Our users run it the same way they run registry lookups: lists of company and person names, checked for litigation exposure.

EU and Ireland: CJEU judgments and Irish courts

The Curia scraper exports Court of Justice of the EU judgments — the rulings that bind interpretation across all member states. The Irish courts scraper covers published judgments from courts.ie.

India eCourts judgments

The India eCourts scraper exports judgments from India's national judiciary portal — case metadata and judgment documents, searchable at a scale the portal's own interface doesn't offer.

Class actions and settlements

The ClassAction.org scraper tracks data-breach lawsuits and settlement announcements — the monitoring layer for breach-response firms and claims aggregators.

German trademarks and patents from DPMA

The DPMA scraper searches Germany's trademark and patent register by mark text, owner, or class — brand-clearance and competitor-watch data for the EU's largest economy, in bulk.

EU trademarks from EUIPO

The EUIPO scraper covers EU-wide trademark registrations: search by mark, owner, or Nice class and export application status, filing dates, and goods/services. Run it beside DPMA for combined national + EU clearance sweeps.

China patents from CNIPA

The CNIPA patent scraper searches China's patent office — with 109 distinct user search terms on our platform, it's one of the most actively queried IP sources we run. Assignee-based searches power competitor filing watches; classification searches power landscape studies.

Immigration filings as a legal dataset: H-1B LCA records

The DOL H-1B LCA crawler exports Labor Condition Application filings — employer, role, wage, and worksite for every H-1B filing. Immigration practices mine it for benchmarks; analysts mine it for hiring and salary signals.

The screening pattern

Legal data work converges on one shape: a list of names — companies, people, marks — swept across jurisdictions on a schedule, with new hits diffed against the last run. Per-record pricing fits that shape: a 200-name monthly litigation sweep costs a few dollars, and adding a jurisdiction is one more scraper on the same input list.
