A copyright infringement case is a federal lawsuit in which the owner of a creative work proves someone copied protected expression from it without permission. Winning requires two things: a valid, registered copyright and proof of copying that goes beyond shared ideas into shared expression. The payoff can be substantial. Statutory damages run from $750 to $30,000 per work, climbing to $150,000 when a court finds the infringement was willful, and the winning side may be awarded attorney’s fees. Smaller disputes now have a second venue — the Copyright Claims Board — which caps total recovery at $30,000 but moves faster and costs less than district court.
What You Have to Prove
Two elements decide the case. The plaintiff must show ownership of a valid copyright, and must show the defendant copied original expression from the protected work.1Ninth Circuit District and Bankruptcy Courts. 17.5 Copyright Infringement – Elements – Ownership and Copying Ownership is usually the easy half if registration is in place. The fight is almost always about copying.
Courts evaluate copying through “substantial similarity.” The question is whether an ordinary observer would find the two works too alike in overall feel and in specific expressive choices. Judges don’t compare raw ideas. They look at how details were selected, arranged, and presented. Some courts split the analysis into an objective test comparing specific elements side by side and a subjective test asking whether the works feel substantially similar as a whole.2Ninth Circuit District and Bankruptcy Courts. 17.19 Substantial Similarity – Extrinsic Test; Intrinsic Test Expert testimony often comes in when the works are technically complex, such as software or architectural plans.
Protection covers the expression, not the underlying idea. You can own a novel about time travel; you cannot own the concept.3U.S. Copyright Office. Compendium of US Copyright Office Practices, Chapter 300 And the work must be fixed in something tangible — a manuscript, a saved file, a recording. An improvised performance that nobody captured doesn’t qualify.
Who Can Be Sued
You don’t have to be the person who made the copy to face liability. Federal courts recognize two forms of secondary infringement that pull third parties into cases.
Contributory infringement applies when someone knows about infringing activity and intentionally helps it along or materially contributes to it.4Ninth Circuit District and Bankruptcy Courts. 17.21 Derivative Liability – Contributory Infringement – Elements and Burden of Proof A website operator who learns users are uploading pirated content and does nothing can be hit with this kind of claim.
Vicarious liability doesn’t require knowledge. It reaches anyone who has the ability to control the infringing activity and profits financially from it. A venue owner who takes a cut from a band performing unlicensed covers can be vicariously liable even without knowing the setlist was unauthorized, as long as the owner had the power to stop the performance.
Where and When You Can File
Copyright cases belong exclusively in federal district court. No state court has jurisdiction over a copyright claim.5Office of the Law Revision Counsel. 28 USC 1338 – Patents, Plant Variety Protection, Copyrights, Mask Works, Designs, Trademarks, and Unfair Competition
Before the courthouse door opens, the Copyright Office must have acted on your registration application. Submitting an application isn’t enough. In Fourth Estate Public Benefit Corp. v. Wall-Street.com, the Supreme Court held that registration “has been made” only after the Office either issues a certificate or formally refuses it.6Supreme Court of the United States. Fourth Estate Public Benefit Corp. v. Wall-Street.com, LLC7Office of the Law Revision Counsel. 17 USC 411 – Registration and Civil Infringement Actions Registering early matters for another reason: statutory damages and attorney’s fees are off the table for works registered after the infringement started, unless registration happens within three months of publication.
Timing also runs against the clock. A civil copyright claim must be filed within three years after it accrued.8Office of the Law Revision Counsel. 17 USC 507 – Limitations on Actions A court will dismiss a stale claim no matter how strong the underlying facts.
What a Win Is Worth
A plaintiff who prevails chooses between two monetary paths. The first is actual damages: the financial harm from the infringement, plus any infringer profits attributable to the copying. The second is statutory damages, which require no proof of a specific dollar loss.9Office of the Law Revision Counsel. 17 USC 504 – Remedies for Infringement: Damages and Profits
Statutory damages run from $750 to $30,000 per work infringed, with the court choosing the amount. A finding of willful infringement raises the ceiling to $150,000 per work. If the infringer proves they had no reason to believe their conduct crossed a line, the floor drops to $200. That span gives courts enormous discretion, and willfulness findings are where the real financial pain lands.
Money isn’t the only remedy. Courts can order the infringer to stop using the work entirely.10Office of the Law Revision Counsel. 17 US Code 502 – Remedies for Infringement: Injunctions They can also order seizure and destruction of infringing copies along with the equipment used to make them.11Office of the Law Revision Counsel. 17 US Code 503 – Remedies for Infringement: Impounding and Disposition of Infringing Articles
Attorney’s Fees
A court has discretion to award reasonable attorney’s fees to whichever side wins.12Office of the Law Revision Counsel. 17 USC 505 – Remedies for Infringement: Costs and Attorneys Fees Fee-shifting isn’t automatic. In Kirtsaeng v. John Wiley & Sons, the Supreme Court said courts should give substantial weight to how objectively reasonable the losing party’s position was, while also considering litigation misconduct and the need to deter both repeated infringement and overaggressive copyright claims.13Justia. Kirtsaeng v. John Wiley and Sons, Inc., 579 US ___ (2016) Copyright litigation is expensive, and a fee award can double the financial consequence of losing.
Defenses That Actually Work
Fair Use
Fair use is the most powerful and most unpredictable defense in copyright law. It allows unauthorized use of copyrighted material for purposes like criticism, commentary, news reporting, teaching, scholarship, or research. Courts weigh four factors:14Office of the Law Revision Counsel. 17 USC 107 – Limitations on Exclusive Rights: Fair Use
- The purpose and character of the use. Commercial uses face more skepticism than nonprofit or educational ones, and courts ask whether the new work is “transformative” in meaning or purpose rather than a substitute for the original.
- The nature of the copyrighted work. Factual or published works get more leeway than highly creative or unpublished ones.
- The amount used. Smaller portions help the defendant, but even a short excerpt can be too much if it captures the heart of the original.
- The market effect. If the new use competes with or replaces the market for the original, this factor cuts strongly against fair use.
No single factor is decisive, and courts have reached opposite results on similar facts. The Supreme Court’s 2023 decision in Andy Warhol Foundation v. Goldsmith tightened the analysis. When an original and a secondary use share the same commercial purpose, the first factor is likely to weigh against fair use even if the new work adds new expression or meaning.15Supreme Court of the United States. Andy Warhol Foundation for the Visual Arts, Inc. v. Goldsmith The degree of transformation has to go beyond what would merely make the new work a derivative. Warhol made it harder to claim fair use for commercial projects that serve essentially the same function as the original.
Independent Creation
A defendant who truly created their work without exposure to the plaintiff’s material has a complete defense. Copyright prohibits copying; it doesn’t grant a monopoly over every possible expression of an idea. Two songwriters can independently arrive at similar songs, and neither has infringed. Defendants support this claim with early drafts, development logs, and file metadata that establish an independent creative timeline.
Smaller Disputes: The Copyright Claims Board
Not every dispute justifies the cost of federal litigation. The Copyright Claims Board, established by the CASE Act, handles claims seeking $30,000 or less in total damages. Statutory damages before the CCB are capped at $15,000 per work for timely-registered works and $7,500 per work for works that weren’t registered before the infringement began.16Office of the Law Revision Counsel. 17 USC 1504 – Copyright Claims Board Proceedings
Participation is voluntary. A respondent has sixty days from the date they receive notice to opt out of the proceeding entirely.17Copyright Claims Board. Respondent Information Opting out ends the CCB case and forces the copyright holder to either refile in federal court or drop the matter. Missing the window agrees you to CCB resolution and waives the right to a federal jury trial. The lower damages cap is the tradeoff: respondents face less financial exposure, but claimants get a faster, cheaper decision.
Online Infringement and the DMCA
The Digital Millennium Copyright Act created a framework for handling online copyright disputes without a full lawsuit every time something infringing is uploaded. Under the DMCA’s safe harbor, online service providers avoid liability for user-posted material if they lack actual knowledge of the infringement, don’t financially benefit from it when they have the ability to control it, and act quickly to remove material once they receive a proper takedown notice.18Office of the Law Revision Counsel. 17 USC 512 – Limitations on Liability Relating to Material Online
Most online disputes play out through the takedown-and-counter-notice system. The copyright holder sends a notice identifying the infringing material. The provider removes it. The user who posted it can file a counter-notice asserting the removal was a mistake. If the copyright holder doesn’t sue within the statutory window, the material goes back up.
The system has a built-in check against abuse. Anyone who knowingly makes a material misrepresentation in a takedown notice or counter-notice is liable for damages, costs, and attorney’s fees incurred by the injured party. Filing fraudulent takedowns to silence competitors or critics creates its own cause of action.
Supreme Court Decisions That Shape the Outcome
Feist v. Rural Telephone (1991)
The Supreme Court held that a phone book of alphabetized names and numbers wasn’t copyrightable. Facts can’t be owned, and organizing them in an obvious way doesn’t supply the minimum creativity the law requires.19Justia. Feist Publications, Inc. v. Rural Tel. Serv. Co., 499 US 340 (1991) Feist killed the “sweat of the brow” theory that had allowed protection based on compilation effort alone. Any case involving databases, directories, or factual compilations now turns on whether the selection or arrangement reflects genuine creative choices.
Google v. Oracle (2021)
Oracle sued Google for copying roughly 11,500 lines of Java code to build the Android platform. The Supreme Court found this was fair use. Google had taken only the declaring code needed to let Java programmers work in a new mobile environment, and the Court treated that as a transformative purpose that served the public interest in innovation and competition.20Supreme Court of the United States. Google LLC v. Oracle America, Inc. The decision remains the leading authority on fair use for software interoperability, though Warhol two years later narrowed what counts as transformative in commercial contexts.
Andy Warhol Foundation v. Goldsmith (2023)
Photographer Lynn Goldsmith took a portrait of Prince that Andy Warhol later used as the basis for a series of silkscreen prints. When Condé Nast licensed one of those prints for a magazine story about Prince, Goldsmith sued. The Court held that because the licensed image served the same commercial purpose as Goldsmith’s original photograph, the first fair use factor favored Goldsmith despite the artistic changes Warhol had made. Adding new expression or meaning isn’t enough on its own when the new work competes in the same market as the original. The decision recalibrated fair use for anyone creating commercial work that draws on existing copyrighted material.
