As new artists jump on the Stability AI, MidJourney copyright lawsuit, the evidence is mounting.

Copyright lawsuits have been filed against several companies that make artificial intelligence (AI) tools, claiming that the artists and their legal teams have misused their creations.

In the year On November 29, a group of visual artists amended the case previously ruled by a US judge, adding seven new artists and more details about the alleged infringement.

New artists include H. Southworth, Grzegorz Rutkowski, Gregory Manches, Gerald Brom, Jingna Zhang, Julia Kay and Adam Ellis.

In the amended class action lawsuit, Stabili A, Midjourney and Deviant Art, along with a new defendant, Runway AI, allege that they created systems that created art in the artists' style with the artists' names suggested to the AI.

The plaintiffs claim that as a result, users have created art that is “indistinguishable” from themselves. According to the artists, AI developers “like to describe their AI image products with high words, but the reality is more boring and more embarrassing.”

“AI image products are primarily valued as copyright infringement tools, where clients hope to gain artistic benefits without the artists' costs.”

Additionally, Midjourney — one of the most popular AI tools for creating art with an estimated 16.4 million users, according to its website — infringed rights under federal trademark laws in the United States.

The claims allege that Midjourney's website advertises a roster of more than 4,700 artists in order to use some of the plaintiffs as generative incentives.

“Recently, Plaintiff Kelly McKernan was surprised to discover that the top Internet search result for his name was now an AI-generated image produced by Midjourney in the name of Mx. McKernan.”

The revised lawsuit argued that “without intervention, this is a dire future that awaits many other artists.”

Earlier, U.S. Magistrate Judge William Orrick dismissed parts of this particular case, citing a lack of evidence from the plaintiffs' side. However, recent changes have allowed plaintiffs to reopen their claims with a new or updated version.

This is one of several cases of copyright infringement at the heart of the complaints against various AI developers in the industry. Other cases include large tech companies including Google, Microsoft and Meta.
