Copyright misuse is an equitable defence to copyright infringement in the United States based upon the doctrine of unclean hands. The misuse doctrine provides that the copyright holder engaged in abusive or improper conduct in exploiting or enforcing the copyright will be precluded from enforcing his rights against the infringer. Copyright misuse is often comparable to and draws from the older and more established doctrine of patent misuse, which bars a patentee from obtaining relief for infringement when he extends his patent rights beyond the limited monopoly conferred by the law.
In re Aimster Copyright Litigation, 334 F.3d 643, was a case in which the United States Court of Appeals for the Seventh Circuit addressed copyright infringement claims brought against Aimster, concluding that a preliminary injunction against the file-sharing service was appropriate because the copyright owners were likely to prevail on their claims of contributory infringement, and that the services could have non-infringing users was insufficient reason to reverse the district court's decision. The appellate court also noted that the defendant could have limited the quantity of the infringements if it had eliminated an encryption system feature, and if it had monitored the use of its systems. This made it so that the defense did not fall within the safe harbor of 17 U.S.C. § 512(i). and could not be used as an excuse to not know about the infringement. In addition, the court decided that the harm done to the plaintiff was irreparable and outweighed any harm to the defendant created by the injunction.
Fogerty v. Fantasy, Inc., 510 U.S. 517 (1994), was a United States Supreme Court case that addressed the standards governing awards of attorneys' fees in copyright cases. The Copyright Act of 1976 authorizes, but does not require, the court to award attorneys' fees to "the prevailing party" in a copyright action. In Fogerty, the Court held that such attorneys'-fees awards are discretionary, and that the same standards should be applied in the case of a prevailing plaintiff and a prevailing defendant.
Capitol Records, Inc. v. Thomas-Rasset was the first file-sharing copyright infringement lawsuit in the United States brought by major record labels to be tried before a jury. The defendant, Jammie Thomas-Rasset, was found liable to the plaintiff record company for making 24 songs available to the public for free on the Kazaa file sharing service and ordered to pay $220,000.
Lexecon Inc. v. Milberg Weiss Bershad Hynes & Lerach, 523 U.S. 26 (1998), was a United States Supreme Court case in which the Court unanimously held that a district court conducting coordinated pretrial proceedings in multiple cases by designation of the Judicial Panel on Multidistrict Litigation under 28 U.S.C. § 1407(a) has no authority to reassign a transferred case to itself for the actual trial of the case. The Court's decision overturned numerous lower-court decisions upholding what had become a common practice in multi-district cases.
Sony Corp. of America v. Universal City Studios, Inc., 464 U.S. 417 (1984), also known as the “Betamax case”, is a decision by the Supreme Court of the United States which ruled that the making of individual copies of complete television shows for purposes of time shifting does not constitute copyright infringement, but is fair use. The Court also ruled that the manufacturers of home video recording devices, such as Betamax or other VCRs, cannot be liable for contributory infringement. The case was a boon to the home video market, as it created a legal safe haven for the technology.
The copyright law of the United States grants monopoly protection for "original works of authorship". With the stated purpose to promote art and culture, copyright law assigns a set of exclusive rights to authors: to make and sell copies of their works, to create derivative works, and to perform or display their works publicly. These exclusive rights are subject to a time limit, and generally expire 70 years after the author's death or 95 years after publication. In the United States, works published before January 1, 1927, are in the public domain.
Substantial similarity, in US copyright law, is the standard used to determine whether a defendant has infringed the reproduction right of a copyright. The standard arises out of the recognition that the exclusive right to make copies of a work would be meaningless if copyright infringement were limited to making only exact and complete reproductions of a work. Many courts also use "substantial similarity" in place of "probative" or "striking similarity" to describe the level of similarity necessary to prove that copying has occurred. A number of tests have been devised by courts to determine substantial similarity. They may rely on expert or lay observation or both and may subjectively judge the feel of a work or critically analyze its elements.
F. W. Woolworth Co. v. Contemporary Arts, Inc. nicknamed The Cocker Spaniel Case, 344 U.S. 228 (1952), is a United States Supreme Court case regarding copyright infringement. The Copyright Act of 1909 allows recovery of either the profits of the infringing company or of the damages suffered by the copyright holder as the legal remedies. When the actual damages cannot be determined, statutory damages can be levied instead. At issue, is whether the trial judge can impose statutory damages when the actual profits of the infringer are known.
In the case of Sony BMG Music Entertainment et al. v. Tenenbaum, record label Sony BMG, along with Warner Bros. Records, Atlantic Records, Arista Records, and UMG Recordings, accused Joel Tenenbaum of illegally downloading and sharing files in violation of U.S. copyright law. It was only the second file-sharing case to go to verdict in the Recording Industry Association of America's (RIAA) anti-downloading litigation campaign. After the judge entered a finding of liability, a jury assessed damages of $675,000, which the judge reduced to $67,500 on constitutional grounds, rather than through remittitur.
Omega S.A. v. Costco Wholesale Corp., 541 F.3d 982, was a case decided by the Ninth Circuit Court of Appeals that held that in copyright law, the first-sale doctrine does not act as a defense to claims of infringing distribution and importation for unauthorized sale of authentic, imported watches that bore a design registered in the Copyright Office. It is contrasted with Kirtsaeng v. John Wiley & Sons, Inc.

Roth Greeting Cards v. United Card Co., 429 F.2d 1106, was a Ninth Circuit case involving the copyright of greeting cards that introduced the "total concept and feel" standard for determining substantial similarity. Courts used this test in later cases such as Reyher v. Children's Television Workshop (1976).
Sid & Marty Krofft Television Productions Inc. v. McDonald's Corp. (1977) was a case in which puppeteers and television producers Sid and Marty Krofft alleged that the copyright in their H.R. Pufnstuf children's television program had been infringed by a series of McDonald's "McDonaldland" advertisements. The finding introduced the concepts of extrinsic and intrinsic tests to determine substantial similarity.
Miller v. Universal City Studios, Inc., is a case where an appeals court found that although the plaintiff apparently deserved to prevail, it reversed the jury verdict and remanded the case for retrial because it found reversible error in the trial judges' instructions to the jury. The appellate court found that the judge's jury instructions, which included the statement that the labor of research by an author is protected by copyright, had been given in error. The court noted that plaintiff, over the objection of the defense, had urged the district court judge to include this instruction.
Columbia Pictures Industries, Inc. v. Fung 710 F.3d 1020 No. 10-55946, was a United States Court of Appeals for the Ninth Circuit case in which seven film studios including Columbia Pictures Industries, Inc., Disney and Twentieth Century Fox sued Gary Fung, the owner of isoHunt Web Technologies, Inc., for contributory infringement of their copyrighted works. The panel affirmed in part and vacated in part the decision of United States District Court for the Central District of California that the services and websites offered by isoHunt Web Technologies allowed third parties to download infringing copies of Columbia's works. Ultimately, Fung had "red flag knowledge" of the infringing activity on his systems, and therefore IsoHunt was held ineligible for the Digital Millennium Copyright Act § 512(c) safe harbor.
