OpenAI’s Sora video tool faced two active trademark lawsuits during its short life, intense copyright and likeness backlash from Hollywood studios, unions, agencies, and the families of deceased public figures, and continuing litigation even after the app was shut down in March 2026. The Sora AI lawsuits that actually reached court were brought by OverDrive, Inc. over the “Sora” name itself and by Baron App, Inc. (operator of Cameo) over the “Cameos” feature. No studio or rightsholder filed a copyright suit specifically targeting Sora before OpenAI pulled the app.
OverDrive v. OpenAI: The Fight Over the Sora Name
OverDrive, Inc. runs a digital library app called Sora that has served roughly 12,000 K-12 school districts since September 2018, and it holds a federal trademark registration for the name granted in December 2020. OpenAI did not file its own trademark application for “Sora” until February 14, 2024.1Accelerate IP. When AI Giants Collide With Educational Tech: The OverDrive vs. OpenAI Sora Trademark Battle

Baron App (Cameo) v. OpenAI: The Feature Name Suit
In September 2025, OpenAI added a Sora feature called “Cameos” that let users scan their faces and insert themselves into AI-generated videos. Baron App, Inc., which operates the celebrity video platform Cameo, filed a trademark infringement and unfair competition lawsuit against OpenAI on October 28, 2025, in the Northern District of California.4CourtListener.

The Copyright Backlash That Didn’t Become a Lawsuit
When OpenAI launched Sora 2 on September 30, 2025, it set rightsholders to opt out of having their copyrighted characters generated. Within days, viral clips showed recognizable characters from SpongeBob SquarePants, South Park, Pokémon, Rick and Morty, and Star Wars in user-generated videos.8The Guardian.

The Motion Picture Association, led by CEO Charles Rivkin, demanded OpenAI “take immediate and decisive action,” arguing that “well-established copyright law safeguards the rights of creators and applies here.”9CNBC.

Despite the volume of complaints, no major studio sued OpenAI over Sora. Reporting at the time attributed the restraint to internal disagreements among MPA members, some of which have their own AI interests, and to caution about legislation that could raise production costs.12Deadline.

OpenAI reversed course within three days. On October 3, 2025, Sam Altman announced a shift from opt-out to opt-in, so copyrighted characters would be restricted unless rightsholders gave express permission. By October 6, OpenAI had implemented guardrails blocking the generation of characters from Family Guy, South Park, and King of the Hill.13Copyright Lately.

Deepfakes of Real People: Family Protests, No Filed Suits
Sora users produced hyper-realistic videos of deceased public figures, most prominently Martin Luther King Jr. Some depicted King saying crude or racist things, stealing from a grocery store, and speeding away from police.16NPR. Sora Block Videos MLK Bernice King, his daughter and CEO of the King Center, called the depictions “foolishness” that “never rose to the level of free speech,” noting that estates can control a deceased person’s likeness for up to 100 years.17Fortune.

On October 16, 2025, OpenAI announced it had paused the ability to generate videos of King and issued a joint statement with the King estate about “strengthening guardrails for historical figures.” The company said “public figures and their families should ultimately have control over how their likeness is used.”18CNN.

Zelda Williams, daughter of the late Robin Williams, condemned the technology after AI-generated videos of her father circulated, including a fabricated Apple ad and a staged interaction with Betty White. In an Instagram post on October 7, 2025, she wrote: “Please, just stop sending me AI videos of Dad.”19Axios. OpenAI Sora Deepfakes Robin Williams George Carlin Ilyasah Shabazz, daughter of Malcolm X, similarly denounced the use of her father’s likeness. None of these families filed formal lawsuits, though legal scholars noted that state right-of-publicity laws and California’s statute protecting deceased persons’ likenesses could support future claims.20Suffolk University Journal of High Technology Law.

OpenAI followed up by announcing collaborations with SAG-AFTRA, United Talent Agency, the Association of Talent Agents, and Creative Artists Agency to strengthen guardrails against unauthorized deepfakes, and it endorsed the federal NO FAKES Act, which would prohibit unauthorized AI-generated replicas of a person’s voice or visual likeness.21CNBC.
