Grokster Ltd. was a privately owned software company based in Nevis, West Indies that created the Grokster peer-to-peer file-sharing client in 2001 that used the FastTrack protocol. Grokster Ltd. was rendered extinct in late 2005 by the United States Supreme Court's decision in MGM Studios, Inc. v. Grokster, Ltd. The court ruled against Grokster's peer-to-peer file sharing program for computers running the Microsoft Windows operating system, effectively forcing the company to cease operations.
Computer Associates International, Inc. v. Altai, Inc., 982 F.2d 693 is a decision from the United States Court of Appeals for the Second Circuit that addressed to what extent non-literal elements of software are protected by copyright law. The court used and recommended a three-step process called the Abstraction-Filtration-Comparison test. The case was an appeal from the United States District Court for the Eastern District of New York in which the district court found that defendant Altai's OSCAR 3.4 computer program had infringed plaintiff Computer Associates' copyrighted computer program entitled CA-SCHEDULER. The district court also found that Altai's OSCAR 3.5 program was not substantially similar to a portion of CA-SCHEDULER 7.0 called SYSTEM ADAPTER, and thus denied relief as to OSCAR 3.5. Finally, the district court concluded that Computer Associates' state law trade secret misappropriation claim against Altai was preempted by the federal Copyright Act. The appeal was heard by Judges Frank Altimari, John Daniel Mahoney, and John M. Walker, Jr. The majority opinion was written by Judge Walker. Judge Altimari concurred in part and dissented in part. The Second Circuit affirmed the district court's ruling as to copyright infringement, but vacated and remanded its holding on trade secret preemption.
Steinberg v. Columbia Pictures Industries, Inc., 663 F. Supp. 706 was a federal case in which artist Saul Steinberg sued various parties involved with producing and promoting the 1984 movie Moscow on the Hudson, claiming that a promotional poster for the movie infringed his copyright in a magazine cover, View of the World from 9th Avenue, he had created for The New Yorker.
Intellectual Reserve, Inc. v. Utah Lighthouse Ministry, Inc., 75 F. Supp. 2d 1290, was a United States district court decision on the subject of deep linking and contributory infringement of copyright.
Castle Rock Entertainment Inc. v. Carol Publishing Group, 150 F.3d 132, was a U.S. copyright infringement case involving the popular American sitcom Seinfeld. Some U.S. copyright law courses use the case to illustrate modern application of the fair use doctrine. The United States Court of Appeals for the Second Circuit upheld a lower court's summary judgment that the defendant had committed copyright infringement. The decision is noteworthy for classifying Seinfeld trivia not as unprotected facts, but as protectable expression. The court also rejected the defendant's fair use defense finding that any transformative purpose possessed in the derivative work was "slight to non-existent" under the Supreme Court ruling in Campbell v. Acuff-Rose Music, Inc., 510 U.S. 569 (1994).
Religious Technology Center v. Netcom On-Line Communication Services, Inc., 907 F. Supp. 1361, is a U.S. district court case about whether the operator of a computer bulletin board service ("BBS") and Internet access provider that allows that BBS to reach the Internet should be liable for copyright infringement committed by a subscriber of the BBS. The plaintiff Religious Technology Center ("RTC") argued that defendant Netcom was directly, contributorily, and vicariously liable for copyright infringement. Netcom moved for summary judgment, disputing RTC's claims and raising a First Amendment argument and a fair use defense. The district court of the Northern District of California concluded that RTC's claims of direct and vicarious infringement failed, but genuine issues of fact precluded summary judgment on contributory liability and fair use.
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.
Arista Records LLC v. Lime Group LLC, 715 F. Supp. 2d 481, is a United States district court case in which the Southern District of New York held that Lime Group LLC, the defendant, induced copyright infringement with its peer-to-peer file sharing software, LimeWire. The court issued a permanent injunction to shut it down. The lawsuit is a part of a larger campaign against piracy by the Recording Industry Association of America (RIAA).
Playboy Enterprises, Inc. v. Starware Publishing Corp. 900 F.Supp. 433 was a case heard before the United States District Court for the Southern District of Florida in May 1995. The case revolved around the subject of copyright infringement and exclusive rights in copyrighted works. Plaintiff Playboy Enterprises filed a motion for partial summary judgment of liability of copyright infringement against defendant Starware Publishing Corporation. Specifically, Playboy Enterprises ("PEI") argued that Starware's distribution of 53 of Playboy's images, taken from an online bulletin board, and then sold on a CD-ROM, infringed upon PEI's copyrights. The case affirmed that it was copyright infringement, granting Playboy Enterprises the partial summary judgment. Most importantly, the case established that "The copyright owner need not prove knowledge or intent on the part of the defendant to establish liability for direct copyright infringement."
Cambridge University Press et al. v. Patton et al., 1:2008cv01425, was a case in the United States District Court for the Northern District of Georgia in which three publishers, Cambridge University Press, SAGE Publications, and Oxford University Press, initially filed suit in 2008 against Georgia State University for copyright infringement.
Reyher v. Children's Television Workshop was a case where the author and illustrator of a children's book sued a company that had published a TV skit and a magazine story with a similar title and plot, claiming copyright infringement. The story was based on an old Russian folk tale. The court found that the plot or theme was not subject to copyright, and there had been no infringement since the book and the story or skit were quite different in all other respects. The court used the "total concept and feel" standard in reaching their decision.
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).
Wainwright Securities v. Wall Street Transcript Corp (1977) was a case in which a weekly newspaper was found to have infringed on the copyright of a publisher of reports that analyzed corporate finances, risks and opportunities. The newspaper's defense that the findings of such reports were news items was rejected, since the newspaper was found to have violated copyright through substantial similarities with the expression used in the Wainwright reports.
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.
Wright v. Warner Books (1991) was a case in which the widow of the author Richard Wright (1908–1960) claimed that his biographer, the poet and writer Margaret Walker (1915–1998), had infringed copyright by using content from some of Wright's unpublished letters and journals. The court took into account the recent ruling in Salinger v. Random House, Inc. (1987), which had found that a copyright owner had the right to control first publication, but found in favor of Walker after weighing all factors. The case had broad implications by allowing the use of library special collections for academic research.
Mandeville-Anthony v. The Walt Disney Company, 11-56441, is a United States Court of Appeals for the Ninth Circuit case in which the Court evaluated whether defendants Pixar, The Walt Disney Company, Disney Enterprises, Inc. and Walt Disney Pictures infringed on Jake Mandeville-Anthony's copyrighted works. Plaintiff Mandeville-Anthony's claim for copyright infringement was first dismissed by the United States District Court for the Central District of California, because the court found that the parties’ works were not substantially similar. Mandeville-Anthony made copyright infringement claims with regards to his works Cookie & Co. and Cars/Auto-Excess/Cars Chaos, an animated television show and movie, that he believed Disney copied in order to make their own films, Cars and Cars 2, both of which were very successful, and the animated television show Cars Toons: Mater's Tall Tales. He also made breach of contract claims stating that he and Disney signed a contract barring Disney from using the ideas contained in his works. The decision was affirmed by the Court of Appeals.
Pearson Education Limited v Morgan Adzei is one of the novel Ghanaian cases that discusses the extent of application and protection under the Copyright Act of Ghana, Act 690.

Pharrell Williams et al. v Bridgeport Music et al., No. 15-56880 is a United States Court of Appeals for the Ninth Circuit case concerning copyright infringement of sound recording. In August 2013, Pharrell Williams, Robin Thicke and Clifford Joseph Harris filed a complaint for declaratory relief against the members of Marvin Gaye's family and Bridgeport Music in the United States District Court for the Central District of California, that the song "Blurred Lines" did not infringe the copyright of defendants in "Got to Give It Up" and "Sexy Ways" respectively.
Marcus Gray et al. v. Katy Perry et al. was a copyright infringement lawsuit against Katy Perry, Jordan Houston, Lukasz Gottwald, Karl Martin Sandberg, Henry Russell Walter ("Cirkut"), Capitol Records and others, in which the plaintiffs Marcus Gray ("Flame"), Emanuel Lambert and Chike Ojukwu alleged that Perry's song "Dark Horse" infringed their exclusive rights in their song "Joyful Noise" pursuant to 17 U.S.C § 106. The focus of the similarity was a short descending pattern known in music as an "ostinato". In both songs, a short ostinato is used repeatedly to form part of the beat of each song and both ostinatos share similar descending shapes. Gray et al. claimed that the instrumental beat of the ostinato in "Joyful Noise" was protectable original expression and that Perry et al. had access to and copied the ostinato when composing "Dark Horse." On March 16, 2020, Judge Christina A. Snyder ultimately found that Gray et al. had failed to satisfy the extrinsic test for substantial similarity, overturning a previous jury verdict which had sided with the plaintiffs. Snyder's ruling was affirmed on appeal.
