Copyright Disputes: Infringement, Defenses, and Remedies

A copyright infringement dispute arises when one party claims another reproduced, distributed, displayed, performed, or adapted a protected work without permission, or used it beyond the scope of a license. Resolving one involves confirming who owns the right that was violated, registering the work with the U.S. Copyright Office, and choosing among three practical forums: a DMCA takedown for online material, the Copyright Claims Board for smaller money claims, or a federal lawsuit for anything larger or more complex. The rules on registration timing, deadlines, defenses, and damages shape the outcome long before a court gets involved.

What Counts as Infringement

Federal law gives a copyright owner exclusive rights to reproduce the work, prepare derivative works, distribute copies, and publicly perform or display it, with an added public performance right by digital audio transmission for sound recordings.1Office of the Law Revision Counsel. 17 USC 106 – Exclusive Rights in Copyrighted Works Anyone who exercises one of those rights without the owner’s permission is potentially an infringer. Profit is not the test; copying protected expression is.

Disputes tend to fall into a few recurring patterns.

Direct infringement is the simplest: someone lifts your photograph off the internet for an ad campaign, or a producer samples a portion of your sound recording without a license. The question is whether they copied your protected expression.

Contributory infringement reaches someone who knowingly helps or encourages another person to infringe, such as a platform providing file-sharing tools while aware users are trading copyrighted material. Vicarious infringement goes further and can apply without actual knowledge: it targets a party who has the right and ability to control the infringing activity and receives a direct financial benefit from it. A venue owner profiting from a band playing unlicensed cover songs can face vicarious liability if the owner could have stopped the performance.

License overreach is treated as infringement too. A software product licensed for five machines but installed on twenty, or a film licensed for U.S. broadcast but streamed abroad, becomes an infringement dispute once use exceeds the agreement.

Who Can Actually Sue

Not everyone upset by copying has standing. Federal law limits suit to the legal or beneficial owner of the specific exclusive right that was violated.2Office of the Law Revision Counsel. 17 U.S. Code 501 – Infringement of Copyright If you hold the exclusive right to distribute a novel in North America and someone pirates it there, you can sue. A non-exclusive licensee generally cannot.

Ownership begins with the creator, with two exceptions for works made for hire. Anything an employee creates within the scope of their job belongs to the employer from the start. Certain commissioned works belong to the hiring party only if both sides sign a written agreement designating the work as made for hire and the work falls into one of the specific statutory categories, such as a contribution to a collective work, a translation, or a part of a motion picture.3Office of the Law Revision Counsel. 17 U.S. Code 101 – Definitions Outside those situations, a transfer of copyright is valid only through a signed written document.4Office of the Law Revision Counsel. 17 U.S. Code 204 – Execution of Transfers of Copyright Ownership

Chain-of-title problems sink cases. A publisher that acquired rights from an author on a handshake has no valid transfer and no standing to enforce the copyright. Before spending money on a dispute, confirm you can prove ownership on paper.

Register the Work Before You File

Copyright exists from the moment a work is fixed in tangible form, but enforcement in federal court does not. You cannot file a federal infringement suit on a U.S. work until you have registered it, or at least submitted a complete application (deposit, application, and fee) to the Copyright Office.5Office of the Law Revision Counsel. 17 USC 411 – Registration and Civil Infringement Actions Without it, the court will dismiss the case.

When you register also decides what you can recover. If you register before the infringement begins, or within three months of first publication, you remain eligible for statutory damages and attorney’s fees. Register later, and you are limited to actual damages and the infringer’s profits.6Office of the Law Revision Counsel. 17 USC 412 – Registration as Prerequisite to Certain Remedies for Infringement The gap between the two paths is large: statutory damages can reach $150,000 per work for willful infringement, while actual damages require proving every dollar of loss.

Standard online registration is $85 as of 2026.7Federal Register. Copyright Office Fees Normal processing runs several months. If you have pending or anticipated litigation, special handling adds $800 on top of the standard fee, with the Office aiming for five business days but not guaranteeing it. The special handling fee is nonrefundable whether or not registration is granted.8U.S. Copyright Office. Special Handling

Three Ways to Resolve the Dispute

DMCA Takedown for Online Material

When the infringement is online, the fastest response is usually a DMCA takedown notice sent to the hosting service provider’s designated agent. A valid notice must be a written communication identifying the copyrighted work and the infringing material with enough detail to locate it, include your contact information, state that you have a good faith belief the use is unauthorized, and include a statement under penalty of perjury that you are authorized to act for the owner.9Office of the Law Revision Counsel. 17 U.S. Code 512 – Limitations on Liability Relating to Material Online Missing an element can render the notice defective. The Copyright Office maintains a public directory of designated agents so you can find the correct contact for each provider.10U.S. Copyright Office. DMCA Designated Agent Directory

Once a service provider receives a valid notice, it must act quickly to remove or disable access and notify the user who posted the material.11U.S. Copyright Office. Section 512 of Title 17 – Resources on Online Service Provider Safe Harbors and Notice-and-Takedown System That user can file a counter-notification, which must include their signature, identify the removed material, state under penalty of perjury that the removal was a mistake, and consent to federal court jurisdiction. After a valid counter-notification, the provider must forward it and restore the material within 10 to 14 business days unless the copyright owner files a federal lawsuit in that window. False statements on either side carry real legal exposure because of the penalty-of-perjury requirement.

The Copyright Claims Board for Smaller Money Claims

The Copyright Claims Board (CCB) is a voluntary tribunal inside the Copyright Office designed for smaller disputes. Proceedings are online, and you do not need a lawyer.

Filing costs $40 upfront, with a second $60 fee once the proceeding becomes active.12U.S. Copyright Office. Copyright Claims Board Handbook – Active Phase Total monetary recovery in a single CCB proceeding is capped at $30,000, with statutory damages limited to $15,000 per work.13Office of the Law Revision Counsel. 17 USC 1504 – Permissible Claims, Counterclaims, and Defenses A “smaller claims” track lowers the total damages ceiling to $5,000.14U.S. Copyright Office. Copyright Claims Board Handbook – Damages

The CCB is voluntary. A respondent has 60 days from service to opt out.15U.S. Copyright Office. Respondent Information If they do, the CCB dismisses the claim and the claimant’s only path is federal court.16U.S. Copyright Office. Copyright Claims Board Handbook – Opting Out You cannot refile the same claim against the same respondent in the CCB without their agreement. The forum works best when both sides prefer a faster, cheaper process to litigation.

Federal Court for Larger or Complex Disputes

If your claim exceeds the CCB cap, involves complex issues, or the respondent opts out, federal court is the forum. You file a complaint and summons and must serve the defendant within 90 days, or the court can dismiss the case.17U.S. Courts. Federal Rules of Civil Procedure Once served, the defendant has 21 days to answer, move to dismiss, or otherwise respond.18Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections Missing that deadline can produce a default judgment.

A cease-and-desist letter before filing is not required, but it eliminates any future claim that the infringement was innocent, gives the other side a chance to stop, and becomes evidence of knowledge if the case proceeds.

The Three-Year Deadline

You must file within three years of when the claim accrued.19Office of the Law Revision Counsel. 17 U.S. Code 507 – Limitations on Actions Courts differ on whether the clock starts when the infringement occurs or when the owner discovers or reasonably should have discovered it. In 2024, the Supreme Court held in Warner Chappell Music v. Nealy that an owner with a timely claim can recover damages for infringement that occurred more than three years before filing, so long as the suit itself was brought within the limitations period. The three-year window limits when you can file, not how far back your damages can reach.

Defenses the Other Side May Raise

Fair Use

Fair use permits limited unauthorized use for purposes like criticism, commentary, news reporting, teaching, and research. Courts weigh four factors together: the purpose and character of the use, including whether it is commercial; the nature of the work; how much of the work was used relative to the whole; and the effect on the market for the original.20Office of the Law Revision Counsel. 17 U.S. Code 107 – Limitations on Exclusive Rights: Fair Use No factor is decisive on its own. A use that is transformative, adding new meaning or purpose rather than substituting for the original, is more likely to qualify.

Independent Creation

Copyright protects against copying, not coincidence. Two songwriters who independently arrive at similar melodies without knowledge of each other’s work have not infringed. Proving independent creation usually requires evidence of the creative process: drafts, development logs, file timestamps, or anything showing the work was made without access to the plaintiff’s work.

Expired Copyright

A work whose term has expired is in the public domain and free to use. As of January 1, 2026, works published in the United States in 1930 or earlier are in the public domain. Watch one trap: a new arrangement, translation, or adaptation of a public domain work can carry its own copyright on the new creative elements.

What a Prevailing Owner Can Recover

Actual damages plus the infringer’s profits are available regardless of when you registered. The owner proves their losses, and the infringer then must prove which profits, if any, came from something other than the infringement.21Office of the Law Revision Counsel. 17 USC 504 – Remedies for Infringement: Damages and Profits Proving actual damages can be expensive and uncertain.

Statutory damages, available only with timely registration, run from $750 to $30,000 per work as the court considers just. Willful infringement raises the ceiling to $150,000 per work. If the infringer proves they had no reason to believe their conduct was infringing, the court can reduce statutory damages to as low as $200 per work. This is the single biggest reason to register early.

Courts can also issue injunctions ordering the infringer to stop, either temporarily during the case or permanently after judgment.22Office of the Law Revision Counsel. 17 U.S. Code 502 – Remedies for Infringement: Injunctions For an owner watching an unauthorized copy circulate in real time, that relief often matters more than money.

Attorney’s fees and costs may be awarded to the prevailing party.23Office of the Law Revision Counsel. 17 U.S. Code 505 – Remedies for Infringement: Costs and Attorney’s Fees Like statutory damages, fees are available only where the copyright was registered on time.6Office of the Law Revision Counsel. 17 USC 412 – Registration as Prerequisite to Certain Remedies for Infringement Awards are discretionary, and courts weigh factors including the strength of the losing party’s position. That possibility can make it economically feasible to pursue claims that would otherwise cost more to litigate than they are worth.

AI-Generated Works

Disputes involving artificial intelligence are a growing category with a specific boundary the searcher should know. The U.S. Copyright Office requires human authorship for registration and refuses to register works it determines were created solely by a machine without creative input from a human. In early 2026, the Supreme Court declined to review a challenge to that policy.

The line the Office draws is between AI as a tool and AI as the creator. A human who uses AI to assist but exercises ultimate creative control over the result can register the work; the Office has registered hundreds of works incorporating AI elements where the human directed, selected, and arranged the output. A work generated entirely by an AI system from a simple prompt, with no meaningful human shaping, is not eligible. That has practical consequences on both sides of a dispute: creators using AI risk having registrations challenged if the AI’s contribution is deemed too substantial, and owners whose work was used to train an AI model face open questions about whether the model’s output infringes. The law here is still moving.
