Copyright infringement occurs when someone violates one of the exclusive rights listed in Commonly, this involves someone creating or distributing a copy of a protected work that is "substantially similar" to the original version. Infringements requires copying. If two people happen to write exactly the same story, without knowledge of the other, there is no infringement.
Copyright infringement litigation The Copyright Office handles copyright registrations, but it does not adjudicate copyright infringement disputes. A copyright owner may bring a copyright infringement lawsuit in federal court. Federal courts have exclusive
subject-matter jurisdiction over copyright infringement cases. That is, an infringement case may not be brought in state courts. An exception applies for works protected under state law but not under federal law; pre-1972 sound recordings fell under this status until the Music Modernization Act brought them under federal copyright law. The latter requires the copyright owner to establish both actual copying and improper appropriation of the work. The copyright owner, as
plaintiff, bears the burden of establishing these elements of the
prima facie case for infringement.
Ownership of valid copyright A plaintiff establishes ownership by authorship (by the plaintiff itself or by someone who assigned rights to the plaintiff) of an original work of authorship that is fixed in a tangible medium (e.g. a book or musical recording). Registration is not required to establish copyright protection, but registration is necessary before bringing a lawsuit. Registration is also useful because it creates a presumption of a valid copyright, allows the plaintiff to collect enhanced "statutory damages", and makes the plaintiff eligible for an award of attorney fees.
Actual copying A plaintiff establishes "actual copying" with direct or indirect evidence. Direct evidence is satisfied either by a defendant's admission to copying or the testimony of witnesses who observed the defendant in the act. More commonly, a plaintiff relies on circumstantial or indirect evidence. A court will infer copying by a showing of a "striking similarity" between the copyrighted work and the alleged copy, along with a showing of both access and use of that access. A plaintiff may establish "access" by proof of distribution over a large geographical area or by eyewitness testimony that the defendant owned a copy of the protected work. Access alone is not sufficient to establish infringement. The plaintiff must show a similarity between the two works, and the degree of similarity will affect the probability that illicit copying in fact occurred in the court's eyes.
Misappropriation A copyrighted work may contain elements that are not copyrightable, such as content in the
public domain, themes, facts, or ideas. A plaintiff alleging misappropriation must first demonstrate that what the defendant appropriated from the copyrighted work was protectable. Second, a plaintiff must show that the intended audience will recognize
substantial similarities between the two works. The intended audience may be the general public, or a specialized field. The degree of similarity necessary for a court to find misappropriation is not easily defined. Indeed, "the test for infringement of a copyright is of necessity vague." Two methods are used to determine if unlawful appropriation has occurred: the "subtractive method" and the "totality method". The subtractive method, also known as the "abstraction/subtraction approach", seeks to analyze which parts of a copyrighted work are protectible and which are not. The unprotected elements are
subtracted and the fact finder then determines whether substantial similarities exist in the protectible expression which remains. For instance, if the copyright holder for
West Side Story alleged infringement, the elements of that musical borrowed from
Romeo and Juliet would be subtracted before comparing it to the allegedly infringing work because
Romeo and Juliet exists in the public domain. The totality method, also known as the "total concept and feel" approach, takes the work as a whole with all elements included when determining if a substantial similarity exists. This was first formulated in
Roth Greeting Cards v. United Card Co. (1970). The individual elements of the alleged infringing work may by themselves be substantially different from their corresponding part in the copyrighted work, but nevertheless taken together be a clear misappropriation of copyrightable material. Modern courts may sometimes use both methods in their analysis of misappropriation. In other instances, one method may find misappropriation while the other would not, making misappropriation a contentious topic in infringement litigation.
Civil remedies A successful copyright infringement plaintiff may seek both injunctive relief and monetary
damages. As of 2019, the United States Supreme Court has held that a copyright holder must register his copyright with the U.S. copyright office before he may seek any judicial remedies for infringement. Copyright Act § 502 authorizes courts to grant both preliminary and permanent injunctions against copyright infringement. There are also provisions for impounding allegedly infringing copies and other materials used to infringe, and for their destruction. Copyright Act § 504 gives the copyright owner a choice of recovering: (1) their actual damages and any additional profits of the defendant; or (2) statutory damages. However, Title 17
United States Code §411(a) states that a civil action to enforce a copyright claim in a US work cannot be made until the work has been registered with the U.S. Copyright Office, with a narrow exception if the claim was filed and rejected by the Copyright Office. In 2019,
the U.S. Supreme Court decided that §411(a) requires that a lawsuit cannot be initiated until the Copyright Office has processed, not merely received, the application.
Equitable relief Both temporary and permanent
injunctions are available to prevent or restrain infringement of a copyright. An injunction is a court order directing the defendant to stop doing something (e.g., stop selling infringing copies). One form of equitable relief that is available in copyright cases is a seizure order. At any time during the lawsuit, the court may order the impoundment of any and all copies of the infringing products. The seizure order may include materials used to produce such copies, such as master tapes,
film negatives, and printing plates. Items that are impounded during the course of the lawsuit can, if the plaintiff wins, be ordered destroyed as part of the final decree.
Monetary damages A copyright holder can also seek monetary damages. Injunctions and damages are not mutually exclusive. One can have injunctions and no damages, damages and no injunctions, or both injunctions and damages. There are two types of damages: actual damages and profits, or statutory damages. The copyright owner may recover the profits they would have earned absent the infringement (actual damages) and any profits the infringer might have made as a result of the infringement but that are not already considered in calculating actual damages. In some cases, the profits earned by the infringer exploiting the copyrighted material may exceed those earned by or potentially available to the owner. In these circumstances, the copyright owner can recover the infringer's profits if a nexus can be demonstrated between the profits and the infringing use.
Statutory damages are sometimes preferable for the plaintiff if actual damages and profits are too small or too difficult to prove. If the copyright was registered either within three months of publication or before the infringement, then the plaintiff is eligible to seek statutory damages. Statutory damages are calculated per work infringed. Statutory damages within the range of $750 to $30,000 per work can be awarded by the court, but the amount can be lowered if the infringement is deemed inadvertent or increased significantly if the infringement is willful: • In case of "innocent infringement", the amount may be reduced to a sum "not less than $200" for an effective range of $200 to $30,000 per work. "Innocent" is a technical term. In particular, if the work carries a copyright notice, the infringer usually cannot claim innocence. • In case of "willful infringement" (again, "willful" is a technical term), statutory damages can be no more than $150,000 for an effective range of $750 to $150,000 per work. a 2003 lawsuit by a publisher of stock analysis newsletters against a company that bought one copy of the newsletters and made multiple copies for use in-house, the jury awarded damages—actual damages for some newsletters and statutory damages for other newsletters—totaling $20 million.
Attorney's fees Copyright Act § 505 permits courts, in their discretion, to award costs against either party and to award reasonable attorney fees to the prevailing party. The court may (but is not required to) award to the "prevailing party" reasonable attorney's fees. This applies to both a winning plaintiff (copyright owner) and a winning defendant (accused infringer). However, attorney's fees award is not available against the government. Like statutory damages, attorney's fees are not available if the work infringed is not registered at the time of infringement.
Criminal penalties In addition to the civil remedies, the Copyright Act provides for criminal prosecution in some cases of willful copyright infringement. There are also criminal sanctions for fraudulent copyright notice, fraudulent removal of copyright notice, and false representations in applications for copyright registration. The
Digital Millennium Copyright Act imposes criminal sanctions for certain acts of circumvention and interference with copyright management information. There are not criminal sanctions for violating the rights of attribution and integrity held by the author of a work of visual art. Criminal penalties for copyright infringement include: • A
fine of not more than $500,000 or
imprisonment for not more than five years, or both, for the first offense. • A fine of not more than $1 million or imprisonment for not more than 10 years, or both, for repeated offenses.
Nonprofit libraries, archives, education institutions and
public broadcasting entities are exempt from criminal prosecution. Felony penalties for first offenses begin at seven copies for audiovisual works, and one hundred copies for sound recordings.
Government infringement The US government, its agencies and officials, and corporations owned or controlled by it, are subject to suit for copyright infringement. All infringement claims against the U.S. that did not arise in a foreign country must be filed with the
United States Court of Federal Claims within three years of the infringing action. Claims filed in the wrong court are dismissed for lack of
subject-matter jurisdiction. The government and its agencies are also authorized to settle the infringement claims out of court. The states have
sovereign immunity provided by the
Eleventh Amendment to the United States Constitution, which bars most forms of lawsuits against states in federal courts, but can be abrogated in certain circumstances by Congress. The Copyright Remedy and Clarification Act of 1990 (CRCA) states in part that states are liable to copyright infringement "in the same manner and to the same extent as any nongovernmental entity" and also that states and state entities and officials "shall not be immune, under the Eleventh Amendment to the Constitution of the United States or under any other doctrine of sovereign immunity, from suit in Federal Court by any person" alleging copyright infringement. The CRCA has been declared unconstitutional by several federal courts., As a result of the ruling,
Nautilus Productions, the plaintiff in
Allen v. Cooper, filed a motion for reconsideration in the United States District Court for the Eastern District of North Carolina. On August 18, 2021, Judge
Terrence Boyle granted the motion for reconsideration which North Carolina promptly appealed to the United States Court of Appeals for the Fourth Circuit. The 4th Circuit denied the state's motion on October 14, 2022. Nautilus then filed their second amended complaint on February 8, 2023, alleging 5th and 14th Amendment violations of Nautilus' constitutional rights, additional copyright violations, and claiming that North Carolina's "
Blackbeard's Law" represents a
bill of attainder. Eight years after the passage of Blackbeard's Law, on June 30, 2023, North Carolina Gov. Roy Cooper signed a bill repealing the law. ==Public domain==
