A federal case over AI generated characters like Tung Tung Sahur is testing whether prompts, model outputs, or no one at all owns an image with no human author.
A wooden stick with a human face, a pair of feet, and a baseball bat has become the unlikely lead plaintiff in a test of U.S. copyright and trademark law. The stick's name is Tung Tung Sahur. It was generated, not drawn. And a federal lawsuit filed in California is now asking a question the relevant statutes were never designed to answer: who, if anyone, owns an image that no human author created?
The case is Spyder Games LLC et al. v. Mementum Lab, filed in federal court and tracked on PACER as case 61479790. Lawyers Josh Geller and Aaron Moss of the firm Mitchell Silberberg & Knupp are counsel of record. The complaint centers on characters born inside an "Italian brainrot" meme wave, a youth-driven aesthetic in which anonymous image generators spit out figures with deliberately broken Italian-sounding names and backstories. Tung Tung Sahur is the most legally exposed of them. He is joined in coverage by Tralalero Tralala (a shark wearing sneakers) and La Vacca Saturno Saturnita (a cow with a ringed planet for a body).
What changed in 2026 is not the meme but the market. Roblox's "Steal A Brainrot", a conveyor-belt game that debuted last spring, turned the contested characters into units players can win, lose, and trade inside a live consumer economy. That gave the dispute a use-in-commerce footprint large enough to put trademark doctrines into play alongside the copyright question. For the first time, the cultural clock and the legal clock are running on the same facts.
The two doctrines will likely answer the ownership question differently, and that is the part of the case a wire read tends to miss. NPR's Geoff Brumfiel frames the fight as one about who owns AI art, but the underlying legal machinery is two machines running on the same input.
U.S. copyright has required a human author since the Supreme Court's 1884 Burrow-Giles ruling, when a photographer was treated as the author of a portrait rather than the sitter in front of the lens. The Copyright Office reaffirmed the human-author line in 2023 when it ruled that purely AI-generated images without sufficient human creative input cannot be registered. A plaintiff claiming to own Tung Tung Sahur under copyright theory has to show the human creativity that shaped him: the prompt writer, the model selector, the editor who chose the final frame. The complaint is widely read in the games press as an attempt to make that showing. GamesBeat and Dexerto both treat the suit as a stress test of that human-author requirement.
Trademark protects source identity: a mark used in commerce that consumers rely on to distinguish one seller's goods from another's. A character mark, once established, can be defended against confusingly similar uses on related goods. The bar is not human authorship; it is consumer recognition. A court that refused copyright protection for lack of a human author can still find trademark rights in a character that players, by the millions, now identify with a particular seller. The doctrinal split is the story. The meme is the vehicle.
The procedural posture, as of the docket snapshot, is the usual early-fight choreography: a complaint, a likely motion to dismiss, and discovery fights over how much of the model, prompt, and curation pipeline the plaintiff has to disclose to make the human-author showing. CourtListener's docket is the cleanest public window into what has been filed. The next milestones to watch are any scheduling order, any ruling on a motion to dismiss, and any U.S. Patent and Trademark Office filings touching the character names. The PACER case page tracks the same record.
Two things the case is not, at least not yet. It is not a verdict on whether AI art can be owned at all. The statutes and the case law are clearer than the discourse suggests: copyright asks for a human; trademark asks for a market. The court will likely answer both questions on narrower grounds. And it is not a referendum on the meme itself. Italian brainrot will keep producing figures with unhinged Italian names whether or not Tung Tung Sahur's bat ever appears in another courtroom filing. The legal question outlives the trend.
What the case can do is set the first federal precedent on what a plaintiff must show to claim ownership of a generative-model output, and what a defendant must show to argue that no one ever owned it. The prompt that produced the image, the curation that selected it, the game that put it in front of paying players: each is a possible hook for one doctrine or the other. The court will sort them. While the docket moves, every artist, studio, and tool vendor shipping AI imagery into a marketplace is operating in the gap between two answers the case will eventually pick from.
The next motion on the docket is the defendant's expected motion to dismiss, which is where the court will first have to decide what kind of author a prompt writer is.
