Studios Fighting AI Copyright Suit Disclose They Used AI to Write the Copyright Suit

LOS ANGELES—Three major Hollywood studios disclosed Friday that their copyright infringement complaint against AI image generator Midjourney — a suit alleging that AI cannot be trusted to use copyrighted creative work without authorization — was drafted in part using AI tools, according to documents produced under a court-ordered discovery review.

The disclosures came after Judge John Kronstadt of the U.S. District Court granted Midjourney's motion to compel internal AI use records, a request the studios had opposed for three months on grounds that their internal deployment was "categorically distinct" from Midjourney's allegedly infringing activity.

Disney confirmed that AI tools were used to "synthesize and summarize" the training-dataset evidence it filed to prove that Midjourney had unlawfully synthesized and summarized copyrighted training data. Warner Bros. confirmed that AI drafted its expert witness declaration detailing the creative harms of AI-generated imagery.

Midjourney's counsel submitted a single-sentence response to the court: "The record speaks for itself."

"We will be amending the complaint," a Disney representative said.

A Universal spokesperson said the studio used AI "responsibly, under meaningful human supervision," and that a paralegal had reviewed all AI-generated legal filings before submission. The paralegal was not available for comment.
