Clean-room design is the method of copying a design by reverse engineering and then recreating it without infringing any of the copyrights associated with the original design. Clean-room design is useful as a defense against copyright infringement because it relies on independent creation. However, because independent invention is not a defense against patents, clean-room designs typically cannot be used to circumvent patent restrictions.
MAI Systems Corp. v. Peak Computer, Inc., 991 F.2d 511, was a case heard by the United States Court of Appeals for the Ninth Circuit which addressed the issue of whether the loading of software programs into random-access memory (RAM) by a computer repair technician during maintenance constituted an unauthorized software copy and therefore a copyright violation. The court held that it did, although the United States Congress subsequently enacted an amendment to 17 U.S.C. § 117 to specifically overrule this holding in the circumstances of computer repair.
In a series of legal disputes between SCO Group and Linux vendors and users SCO alleged that its license agreements with IBM meant that source code IBM wrote and donated to be incorporated into Linux was added in violation of SCO's contractual rights. Members of the Linux community disagreed with SCO's claims; IBM, Novell and Red Hat filed claims against SCO.
Beginning in 2003, The SCO Group was involved in a dispute with various Linux vendors and users. SCO initiated a series of lawsuits, the most known of which were SCO v. IBM and SCO v. Novell, that had implications upon the futures of both Linux and Unix. SCO claimed that Linux violated some of SCO's intellectual properties. Many industry observers were skeptical of SCO's claims, and they were strongly contested by SCO's opponents in the lawsuits, some of which launched counter-claims. By 2011, the lawsuits fully related to Linux had been lost by SCO or rendered moot and SCO had gone into bankruptcy. However the SCO v. IBM suit continued for another decade, as it included contractual disputes related to both companies' involvement in Project Monterey in addition Linux-related claims. Finally in 2021 a settlement was reached in which IBM paid the bankruptcy trustee representing what remained of SCO the sum of $14.25 million.

Apple v. Does was a high-profile legal proceeding in United States of America notable for bringing into question the breadth of the shield law protecting journalists from being forced to reveal their sources, and whether that law applied to online news journalists writing about corporate trade secrets. The case was also notable for the large collection of amici curiae who joined in the matter.
MGM Studios, Inc. v. Grokster, Ltd., 545 U.S. 913 (2005), is a United States Supreme Court decision in which the Court unanimously held that defendant peer-to-peer file sharing companies Grokster and Streamcast could be sued for inducing copyright infringement for acts taken in the course of marketing file sharing software.

The Uniform Trade Secrets Act (UTSA), published by the Uniform Law Commission (ULC) in 1979 and amended in 1985, is a Uniform Act promulgated for adoption by states in the United States. One goal of the UTSA is to make the state laws governing trade secrets uniform, which is especially important for companies that operate in more than one state. Historically, the law governing misappropriation of trade secrets developed separately in each state.
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.
Vault Corporation v Quaid Software Ltd. 847 F.2d 255 is a case heard by the United States Court of Appeals for the Fifth Circuit that tested the extent of software copyright. The court held that making RAM copies as an essential step in utilizing software was permissible under §117 of the Copyright Act even if they are used for a purpose that the copyright holder did not intend. It also applied the "substantial noninfringing uses" test from Sony Corp. of America v. Universal City Studios, Inc. to hold that Quaid's software, which defeated Vault's copy protection mechanism, did not make Quaid liable for contributory infringement. It held that Quaid's software was not a derivative work of Vault's software, despite having approximately 30 characters of source code in common. Finally, it held that the Louisiana Software License Enforcement Act clause permitting a copyright holder to prohibit software decompilation or disassembly was preempted by the Copyright Act, and was therefore unenforceable.
Jacobsen v. Katzer was a lawsuit between Robert Jacobsen (plaintiff) and Matthew Katzer (defendant), filed March 13, 2006 in the United States District Court for the Northern District of California. The case addressed claims on copyright, patent invalidity, cybersquatting, and Digital Millennium Copyright Act issues arising from Jacobsen under an open source license developing control software for model trains.
MDY Industries, LLC v. Blizzard Entertainment, Inc and Vivendi Games, Inc., 629 F.3d 928, is a case decided by the United States Court of Appeals for the Ninth Circuit. At the district court level, MDY had been found liable under theories of copyright and tort law for selling software that contributed to the breach of Blizzard's End User License Agreement (EULA) and Terms of Use (ToU) governing the World of Warcraft video game software.
The court's ruling was appealed to the United States Court of Appeals for the Ninth Circuit, which reversed the district court in part, upheld in part, and remanded for further proceedings. The Court of Appeals ruled that for a software licensee's violation of a contract to constitute copyright infringement, there must be a nexus between the license condition and the licensor’s exclusive rights of copyright. However, the court also ruled, contrary to Chamberlain v. Skylink, that a finding of circumvention under the Digital Millennium Copyright Act does not require a nexus between circumvention and actual copyright infringement.
Comprehensive Technologies International, Inc. v. Software Artisans, Inc., 3 F.3d 730 was a case in which the U.S. Court of Appeals for the Fourth Circuit discussed legal tests for software copyright infringement, and ruled that trade secret misappropriation requires more than circumstantial evidence. The case also ruled on what terms may be reasonable and enforceable in non-compete agreements.
DVD Copy Control Association, Inc. v. Bunner was a lawsuit that was filed by the DVD Copy Control Association in California, accusing Andrew Bunner and several others of misappropriation of trade secrets under California's implementation of the Uniform Trade Secrets Act. The case went through several rounds of appeals and was last heard and decided in February 2004 by the California Court of Appeal for the Sixth District.
Asset Marketing Systems, Inc. v. Gagnon was a case heard by the United States Court of Appeals for the Ninth Circuit regarding implied licenses to use, modify and retain the source code of computer programs, and the enforceability of non-competition agreements. The court affirmed the ruling from the United States District Court for the Southern District of California that Kevin Gagnon, a software contractor doing business as "Mr. Computer", had implicitly granted Asset Marketing Systems (AMS) an unlimited license to use, modify and retain the source code of the programs that Gagnon created. The case is notable because the Court held that an implied software license is granted when the licensee requests the creation of a work, the licensor creates and delivers the work, and the licensor intends the licensee to copy and distribute the work.
Structure, sequence and organization (SSO) is a term used in the United States to define a basis for comparing one software work to another in order to determine if copying has occurred that infringes on copyright, even when the second work is not a literal copy of the first. The term was introduced in the case of Whelan v. Jaslow in 1986. The method of comparing the SSO of two software products has since evolved in attempts to avoid the extremes of over-protection and under-protection, both of which are considered to discourage innovation. More recently, the concept has been used in Oracle America, Inc. v. Google, Inc.
Brown Bag Software v. Symantec Corp. is an intellectual property law case in which the United States Court of Appeals for the Ninth Circuit affirmed-in-part and vacated-in-part the previous ruling of the United States District Court for the Northern District of California. Brown Bag Software sued Symantec Corporation and John L. Friend, an individual software developer for Softworks Development, for copyright infringement and several state law claims regarding the similarity of Symantec Corporation's and Brown Bag Software's computer outlining programs.
Ajaxo Inc. v. E*Trade Financial Corp., 187 Cal.App.4th 1295 (2010), is the second appeal on a dispute dated back to 1999. During the original 2000 case, defendant E*Trade, an online financial services company, was found liable for maliciously and willfully misappropriating trade secrets pertaining to wireless stock trading technology acquired from the plaintiff, Ajaxo. Under the Uniform Trade Secrets Act E*Trade was required under a mutually signed Non-disclosure agreement (NDA) to keep Ajaxo's trade secrets confidential. After a jury trial in 2003, E*Trade was fined $1.3 million to be paid to Ajaxo for the misappropriation and breach of NDA. The court denied Ajaxo's request for additional damages. All parties appealed. In 2005 the California courts of appeal affirmed the original ruling but remanded the case back to the trial court to determine additional damages. A jury verdict in 2008 rejected claims raised and demands for royalty damages from Ajaxo. In trade secret cases it is common for a plaintiff to seek royalty damages when they are unable to show an actual loss or that the defendant received some inequitable benefit from the misappropriation. In this case the court refused to allow evidence of royalty damages, claiming there were no net damages. Ajaxo appealed. In 2010 the California courts of appeal once again remanded the case back to the trial court reasoning that in such cases an exact quantitative measure of wrongful enrichment damages incurred by the plaintiff might not be sufficient to reject the claim of reasonable royalties based damages
Cadence Design Systems, Inc. v. Avanti Corp was a major legal battle between two semiconductor companies, Cadence Design Systems and Avanti Corporation, that lasted for more than six years, and was fought over stolen technology.
Open source license litigation involves lawsuits surrounding open-source licensed software. Many of the legal rights of open source software licensors enforceable against users violating licensing agreements are untested by the U.S. legal system. Free and open source software (FOSS) is distributed under a variety of free-software licenses, which are unique among other software licenses. Legal action against open source licenses involves questions about their validity and enforceability.
