Famous Copyright Infringement Cases That Shaped the Law

The most famous copyright infringement cases in American law come from music, visual art, books, software, and now artificial intelligence, and together they define where inspiration ends and unlawful copying begins. Each dispute below either changed the rules or clarified them: what “transformative” really means, whether a groove can be owned, when a platform is liable for its users, and what happens when a song sounds too much like one you already know. Nearly all of them turn on the same statutory test, so that is where to start.

The Fair Use Test Behind Almost Every Case

Federal copyright law gives authors exclusive rights to reproduce, distribute, and adapt their work.¹ Fair use is the main defense to an infringement claim, and courts weigh four factors:²

The purpose and character of the use, including whether it is commercial and whether it transforms the original into something with a different purpose.
The nature of the original work, with creative works getting stronger protection than factual ones.
The amount taken, and whether the portion used was the heart of the original.
The effect on the market for the original.

No factor decides the case alone. The same test has produced very different outcomes across the disputes below, which is exactly why these cases are worth knowing.

Music: Grooves, Melodies, and Basslines

Williams v. Gaye (Blurred Lines)

Pharrell Williams and Robin Thicke’s 2013 hit “Blurred Lines” was found to infringe Marvin Gaye’s 1977 “Got to Give It Up.” The Gaye family’s experts pointed not to a shared melodic line but to rhythmic patterns, instrumentation, and overall feel. The jury sided with the estate, and after post-trial rulings the award landed at roughly $5.3 million in damages and profits, plus a 50% running royalty on future songwriter and publishing revenues.³

The verdict rattled the industry because it suggested copyright can reach the overall groove of a song, not just a specific melody. The appellate dissent warned that the ruling could expose anyone capturing a genre’s characteristic sound to liability. Producers have been more cautious about emulating the feel of an existing track ever since.

Bright Tunes Music v. Harrisongs (My Sweet Lord)

George Harrison’s 1970 solo hit “My Sweet Lord” was compared to the Chiffons’ 1963 “He’s So Fine,” and the court found the two shared a distinctive melodic sequence too close to be coincidence.⁴ Harrison acknowledged he knew the earlier song but denied intentional copying. The judge accepted that the copying was subconscious and ruled it made no difference. If the melodies match, the infringement exists. Harrison was ordered to pay approximately $587,000.

This is the leading authority for the rule that copyright infringement does not require a guilty mind. A songwriter who absorbs a melody so thoroughly that it feels original still infringes when they publish it.

Vanilla Ice and “Under Pressure”

Vanilla Ice built “Ice Ice Baby” (1990) around the bassline from Queen and David Bowie’s 1981 “Under Pressure.” He initially argued that adding one note made the riff different, an argument that did not survive contact with the actual music. The parties settled privately: Queen and Bowie received songwriting credits, and Vanilla Ice reportedly paid $4 million to acquire publishing rights to “Under Pressure.” Distinctive instrumental hooks get the same protection as vocal melodies, and a cosmetic tweak does not create a new work.

Visual Art: Medium, Meaning, and Purpose

Rogers v. Koons

Photographer Art Rogers had licensed a photograph called “Puppies.” Sculptor Jeff Koons tore the image from a postcard, sent it to Italian artisans, and had them replicate the composition as a painted wooden sculpture titled “String of Puppies.”⁵ Koons defended the sculpture as commentary on mass-produced consumer culture. The Second Circuit rejected the fair use defense, finding that the sculpture copied the photograph’s creative expression wholesale rather than commenting on the image itself.⁶ Koons was ordered to pay damages and surrender the remaining sculptures. Changing the medium is not, by itself, transformation.

The Obama “Hope” Poster

Shepard Fairey created the “Hope” poster of then-Senator Barack Obama using an Associated Press photograph as reference, without a license.⁷ When the AP asserted its rights, Fairey filed first, seeking a declaration of fair use. The civil case settled on confidential financial terms, with the parties agreeing to share rights in the Hope image going forward.

The lasting damage came from Fairey’s conduct in the litigation. He first claimed he had used a different photograph, then destroyed evidence to support that story. Federal prosecutors charged him with criminal contempt, and he was sentenced to two years of probation, 300 hours of community service, and a $25,000 fine.⁸ The underlying copyright question was genuinely close; the cover-up turned a civil dispute into a criminal case.

Andy Warhol Foundation v. Goldsmith

This 2023 Supreme Court decision is the most consequential fair use ruling in a generation. Lynn Goldsmith photographed Prince in 1981. Andy Warhol used the photograph to create a series of silkscreen prints. After Prince’s death in 2016, Condé Nast licensed one of them, “Orange Prince,” for a magazine cover tribute. Goldsmith sued.⁹

The Warhol Foundation argued the print conveyed a different meaning and message, which made it transformative. In a 7-2 decision, the Court disagreed. The first fair use factor asks whether the new work has a different purpose or character, not merely a different artistic meaning. Because Condé Nast licensed Orange Prince for the same purpose Goldsmith’s photograph would have served, illustrating a magazine feature about Prince, the commercial licensing was not transformative enough to favor fair use.⁹

The practical shift is real. Adding new artistic expression to someone’s work does not automatically protect you. Courts now weigh how the new work is being used in context, and a stylized version licensed for the same commercial purpose as the original faces a much steeper defense.

Books and Characters

The Harry Potter Lexicon

A fan reference guide called the “Harry Potter Lexicon” tried to move from website to printed book, cataloging spells, creatures, and characters from J.K. Rowling’s novels. Rowling and Warner Bros. sued. The court found the lexicon copied extensive passages of Rowling’s descriptive prose without adding enough original analysis or commentary to qualify as fair use, and it permanently blocked publication. Statutory damages came to $6,750.¹⁰ The money was small; the injunction killed the book. Reference guides built around a fictional universe still need to demonstrate genuine transformation rather than reorganizing someone else’s writing.

Sherlock Holmes and the Public Domain

The Arthur Conan Doyle estate long claimed that Sherlock Holmes remained partly protected because later stories added new traits like emotional warmth. A federal court rejected the position, ruling that the defining characteristics of Holmes appear in early stories already in the public domain, and that only elements first introduced in still-protected works remained off-limits. On January 1, 2023, the last Conan Doyle stories, published in 1927, entered the public domain, ending the fight. The principle survives for other characters: when a character appears across works with different expiration dates, traits enter the public domain piecemeal until the last work expires.

Digital Platforms and Software Code

A&M Records v. Napster

Napster operated a peer-to-peer network that let users search and download music files from each other’s computers.¹¹ Napster did not host the files, but it maintained a central index and knew massive infringement was happening on the service. The Ninth Circuit found the company liable on two independent theories: contributory infringement, because it knowingly facilitated illegal sharing, and vicarious infringement, because it profited from that activity and had the ability to stop it.¹² Napster shut down and paid approximately $26 million to record labels and publishers. Every later platform inherited the rule: build a system that facilitates infringement, profit from it, and fail to police it, and you share liability with the users doing the copying.

Google v. Oracle

Google copied roughly 11,500 lines of Java API declarations to build the Android operating system. Oracle, which owned Java, sued. In 2021, the Supreme Court held 6-2 that Google’s copying was fair use as a matter of law. Google took only what programmers needed to apply existing Java skills on a new platform, and it reimplemented the interface in a fundamentally different computing environment.¹³ API declarations function like a programming language’s vocabulary; locking them behind copyright would force developers to relearn equivalent commands each time they switched platforms. The decision keeps that vocabulary open.

AI-Generated Works and the Human Authorship Rule

The newest front is artificial intelligence. The Copyright Office has taken the position that works generated entirely by AI, without meaningful human creative input, cannot be registered. The Office treats such output the way it treats works produced by nature or by machines operating without human direction.¹⁴

Works that combine human creativity with AI assistance can be registered, but only for the human-authored portions. Applicants must disclose AI use, describe the human contributions, and exclude AI-generated material that goes beyond a trivial amount.¹⁴ Federal courts have upheld the human authorship requirement. Meanwhile, lawsuits from visual artists, authors, and music publishers against AI companies over training data are working through the courts, and their outcomes will likely define the next chapter as forcefully as Napster defined the last one.

What Infringement Costs

Copyright holders who registered their work before the infringement, or within three months of publication, can elect statutory damages instead of proving actual losses:

Standard infringement: $750 to $30,000 per work, at the court’s discretion.
Willful infringement: up to $150,000 per work, if the copyright holder proves the infringer acted intentionally.
Innocent infringement: as low as $200 per work, if the infringer proves they had no reason to know they were infringing.

Awards are calculated per work infringed, not per copy made.¹⁵ Distributing a thousand illegal copies of one song produces one statutory award; infringing ten songs in one project produces ten. That math is what makes cases involving large catalogs so dangerous.

A copyright holder must file suit within three years of when the claim accrues. Courts have split on whether the clock starts when the infringement occurs or when the holder discovers it. The Supreme Court held in 2024 that once a claim is timely filed, there is no separate three-year cap on how far back damages can reach; a plaintiff who discovers years of past infringement and sues within three years of that discovery can recover for the full period.¹⁶ For a copyright owner who has just discovered old infringement, that ruling can be the difference between a small case and a very large one.
