Today, the U.S. Supreme Court issued an order list including the denial of a petition for writ of certiorari filed by Dr. Stephen Thaler that challenged federal agency and court rulings preventing copyright registration for an image generated entirely by artificial intelligence (AI). In following the U.S. Solicitor General’s call to deny cert to Thaler’s appeal, the Supreme Court declined invitations from both sides of the AI authorship debate to clarify the copyrightability of works that are substantially AI-generated.

As the AI revolution accelerates and continues to reshape traditional business models, it has triggered a cascade of new legal, regulatory and policy challenges. At the forefront of these emerging issues are a growing number of high-stakes legal battles between content creators and major Generative AI (GenAI) companies behind large language models (LLMs). This article examines key legal themes and critical questions arising from recent developments at the intersection of AI and Copyright law.

Concord Music Group, Inc., Universal Music Group, and ABKCO Music, Inc. filed a complaint on Wednesday for copyright and Digital Millennium Copyright Act (DMCA) violations against Anthropic PBC, Dario Amodei, and Benjamin Mann in the U.S. District Court for the Northern District of California, adding another lawsuit against generative artificial intelligence companies. The publishers alleged that Anthropic engaged in mass piracy by downloading millions of unauthorized copies of books containing their copyrighted musical compositions from notorious pirate library websites, including Library Genesis (LibGen) and Pirate Library Mirror (PiLiMi). The complaint argued that Anthropic used BitTorrent to acquire these works and subsequently trained its Claude AI models on the stolen content, thereby directly infringing the publishers’ exclusive rights and undermining the music licensing market.

On January 23, the United States Department of Justice (DOJ) urged the U.S. Supreme Court to reject a petition from Stephen Thaler, who seeks copyright protection for a work created by his artificial intelligence (AI) system. The DOJ argued that the U.S. Court of Appeals for the District of Columbia Circuit correctly upheld the United States Copyright Office’s refusal to register a copyright for an image that was admittedly created without human authorship.

On Friday, January 23, the U.S. Court of Appeals for the Fourth Circuit issued a ruling in Allen v. Stein that likely ends a decade-long copyright battle over documentary footage of a state-sponsored salvage project exhuming a shipwreck associated with the famed pirate Blackbeard. Reversing and vacating rulings by the Eastern District of North Carolina, the Fourth Circuit found that an erroneous legal standard was used in allowing Allen to pursue a new theory for his copyright claims, remanding the case to the district court with directions to dismiss Allen’s complaint with prejudice.

On January 22, the Human Artistry Campaign, on behalf of a broad cross-section of the American creative community, launched a new advocacy campaign, titled “Stealing Isn’t Innovation.” The campaign’s core message is a direct protest against the “illegal mass harvesting of copyrighted works” by large technology companies to build and train their Generative Artificial Intelligence (GenAI) platforms.

The U.S. District Court for the Northern District of California on Tuesday granted summary judgment in favor of Pinterest, Inc. in a copyright infringement suit brought by the estate of a professional photographer, finding that the social media platform is protected by the Digital Millennium Copyright Act’s (DMCA) safe harbor provision.

The U.S. Court of Appeals for the Ninth Circuit on Friday affirmed a district court’s grant of summary judgment in favor of Paramount Pictures Corporation in a copyright and contract dispute brought by the heirs of the author of the 1983 magazine article that inspired the original Top Gun film. Shosh Yonay and Yuval Yonay, the widow and son of Ehud Yonay, first brought claims against Paramount in 2022, alleging that the sequel Top Gun: Maverick infringed on the copyright of Ehud Yonay’s article, “Top Guns.” The U.S. District Court for the Central District of California in 2024 granted summary judgment for Paramount, agreeing that Maverick did not share “substantial amounts of the article’s original expression and that the depicted pilots and their experiences were factual and therefore unprotected by copyright law.

Much of the focus on generative artificial intelligence (GenAI) has been on training data ingestion—the moment when AI “steals” from creators. But legally, that’s not where the real fight should be. Decades of legal precedent—from search engines to image?scanning to streaming media—already give us a roadmap. No new formulation of copyright law by Congress, as suggested by some academics, is necessary. By considering these seven unique aspects of GenAI systems, copyright analysis is actually easy.

On December 19, Google LLC filed a complaint in the U.S. District Court for the Northern District of California against SerpApi, LLC, alleging violations of the Digital Millennium Copyright Act (DMCA). The suit centers on claims that SerpApi, a “scraping” service, unlawfully circumvents Google’s technological barriers to scrape copyrighted content from its search results pages on a massive scale, thereby profiting from Google’s efforts without compensation.

The battle over whether U.S. copyright law permits artificial intelligence (AI) training on copyrighted works is no longer a theoretical debate. In 2025, three federal district court decisions began to sketch the boundaries of what counts as fair use in this context.

In a year dominated by artificial intelligence (AI) copyright cases, 2025 also featured several influential cases on traditional copyright issues that will impact copyright owners, internet service providers, website owners, advertisers, social media users, media companies, and many others. Although the U.S. Supreme Court did not decide a copyright case this year, it heard argument on secondary liability and willfulness issues in Cox v. Sony. Lower courts continued to wrestle with applying the fair use factors two years after the Supreme Court issued Warhol v. Goldsmith. The divide over whether the “server test” applies to embedded works deepened—and remains unsettled. And the Ninth Circuit further refined the standard for pleading access to online works. This article highlights some of the most important copyright cases from this year and their practical implications.

The U.S. Court of Appeals for the Second Circuit on Tuesday dismissed an appeal from Zuru Inc. in its ongoing copyright and trademark dispute with the Lego group, finding that the court lacked appellate jurisdiction. Lego A/S, Lego Systems, Inc., and Lego Juris A/S first brought claims against Zuru Inc. in 2019, alleging that Zuru’s “First-Generation” toy figurines infringed on the copyright and trademark rights of Lego’s Minifigure. The U.S. District Court for the District of Connecticut granted Lego’s motion for a preliminary injunction, which enjoined Zuru from manufacturing or selling the infringing First-Generation figurines and “any figurine or image that is substantially similar to the Minifigure Copyrights or likely to be confused with the Minifigure Trademarks.”

On December 5, The New York Times Company (the Times) filed a complaint for copyright and trademark infringement against Perplexity AI, Inc. in the U.S. District Court for the Southern District of New York, adding another major lawsuit to the growing wave of litigation against generative artificial intelligence (AI) companies. The Times alleged in its filing that Perplexity engaged in “large-scale, unlawful copying and distribution” of millions of its articles to build its AI-powered “answer engine.” The complaint argued that Perplexity’s products directly substitute for the newspaper’s own content, thereby undermining its business and devaluing its journalism. Perplexity’s conduct “threatens this legacy and impedes the free press’s ability to continue playing its role in supporting an informed citizenry and a healthy democracy,” the Times argued.
