An end-user license agreement or EULA is a legal contract between a software supplier and a customer or end-user, generally made available to the customer via a retailer acting as an intermediary. An EULA specifies in detail the rights and restrictions which apply to the use of the software.
bnetd is a communication app that enables users of the online game StarCraft released on March 31, 1998 to connect and chat together. Bnetd was released on April 28, 1998 under the name StarHack and provided near-complete emulation of the original online multiplayer gaming service network. This was accomplished through reverse engineering of the corporate Blizzard Entertainment's Battle.net.
Step-Saver Data Systems, Inc. v. Wyse Technology was a case in the U.S. Court of Appeals for the Third Circuit primarily concerned with the enforceability of box-top licenses and end user license agreements (EULA) and their place in U.S. contract law. During the relevant period, Step-Saver Data Systems was a value-added reseller, combining hardware and software from different vendors to offer a fully functioning computer system to various end users. Step-Saver's products included software produced by Software Link, Inc (TSL), computer terminals produced by Wyse Technology, and main computers produced by IBM. The fundamental question raised in this case was whether the shrinkwrap licenses accompanying TSL's software were legally binding, given that different terms were negotiated over the phone with Step-Saver prior to receiving physical copies of the software. The case was first heard in the United States District Court for the Eastern District of Pennsylvania, where the court ruled that the shrinkwrap licenses were legally binding. However, the U.S. Court of Appeals for the Third Circuit subsequently reversed this decision, ruling that the shrinkwrap licenses were not legally binding.
Software copyright is the application of copyright in law to machine-readable software. While many of the legal principles and policy debates concerning software copyright have close parallels in other domains of copyright law, there are a number of distinctive issues that arise with software. This article primarily focuses on topics particular to software.
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.
Shrinkwrap contracts or shrinkwrap licenses are boilerplate contracts packaged with products; use of the product is deemed acceptance of the contract.
A clickwrap or clickthrough agreement is a prompt that offers individuals the opportunity to accept or decline a digitally-mediated policy. Privacy policies, terms of service and other user policies, as well as copyright policies commonly employ the clickwrap prompt. Clickwraps are common in signup processes for social media services like Facebook, Twitter or Tumblr, connections to wireless networks operated in corporate spaces, as part of the installation processes of many software packages, and in other circumstances where agreement is sought using digital media. The name "clickwrap" is derived from the use of "shrink wrap contracts" commonly used in boxed software purchases, which "contain a notice that by tearing open the shrinkwrap, the user assents to the software terms enclosed within".
The exhaustion doctrine, also referred to as the first sale doctrine, is a U.S. common law patent doctrine that limits the extent to which patent holders can control an individual article of a patented product after a so-called authorized sale. Under the doctrine, once an authorized sale of a patented article occurs, the patent holder's exclusive rights to control the use and sale of that article are said to be "exhausted," and the purchaser is free to use or resell that article without further restraint from patent law. However, under the repair and reconstruction doctrine, the patent owner retains the right to exclude purchasers of the articles from making the patented invention anew, unless it is specifically authorized by the patentee to do so.
ProCD, Inc. v. Zeidenberg, 86 F.3d 1447, was a court ruling at the United States Court of Appeals for the Seventh Circuit. The case is a significant precedent on the matter of the applicability of American contract law to new types of shrinkwrap licenses that arose with home computing and the Internet in the 1990s, and whether such licenses are enforceable contracts.
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.
Browsewrap is a term used in Internet law to refer to a contract or license agreement covering access to or use of materials on a web site or downloadable product. In a browse-wrap agreement, the terms and conditions of use for a website or other downloadable product are posted on the website, typically as a hyperlink at the bottom of the screen. Unlike a clickwrap agreement, where the user must manifest assent to the terms and conditions by clicking on an "I agree" box, a browse-wrap agreement does not require this type of express manifestation of assent. Rather, a web-site user purportedly gives their consent simply by using the product — such as by entering the website or downloading software.
Quanta Computer, Inc. v. LG Electronics, Inc., 553 U.S. 617 (2008), is a case decided by the United States Supreme Court in which the Court reaffirmed the validity of the patent exhaustion doctrine. The decision made uncertain the continuing precedential value of a line of decisions in the Federal Circuit that had sought to limit Supreme Court exhaustion doctrine decisions to their facts and to require a so-called "rule of reason" analysis of all post-sale restrictions other than tie-ins and price fixes. In the course of restating the patent exhaustion doctrine, the Court held that it is triggered by, among other things, an authorized sale of a component when the only reasonable and intended use of the component is to engage the patent and the component substantially embodies the patented invention by embodying its essential features. The Court also overturned, in passing, that the exhaustion doctrine was limited to product claims and did not apply to method claims.
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.
Vernor v. Autodesk, Inc. was a case in the United States District Court for the Western District of Washington regarding the applicability of the first-sale doctrine to software sold under the terms of so-called "shrinkwrap licensing." The court held that when the transfer of software to the purchaser materially resembled a sale it was, in fact, a "sale with restrictions on use" giving rise to a right to resell the copy under the first-sale doctrine. As such, Autodesk could not pursue an action for copyright infringement against Vernor, who sought to resell used versions of its software on eBay. The decision was appealed to the United States Court of Appeals for the Ninth Circuit, which issued a decision on September 10, 2010, reversing the first-sale doctrine ruling and remanding for further proceedings on the misuse of copyright claim. The Ninth Circuit's decision asserted that its ruling was compelled by Ninth Circuit precedent, but observed that the policy considerations involved in the case might affect motion pictures and libraries as well as sales of used software.
Lasercomb America, Inc. v. Reynolds, 911 F.2d 970 is an appeal filed in the United States Court of Appeals for the Fourth Circuit. Initially, Lasercomb filed an action against Holiday Steel for breach of contract, copyright infringement, misappropriation of trade secrets, fraud, unfair competition, and false designation of origin. The United States District Court ruled in favor of Lasercomb, awarding them punitive damages and actual damages for fraud, rejecting the defense of copyright misuse. On appeal, based on a recognition of the similarity to patent misuse, the holding was reversed, deeming the language contained in the license agreement unreasonable.
The Louisiana Software License Enforcement Act refers to the Software License Enforcement Act (SLEA) adopted by the state of Louisiana. The bill was voted into law in September 1984 under Title 51 of the Louisiana Revised Statutes by the Louisiana State Legislature. Sponsored and mostly written by Vault Corporation, the SLEA defines the permissible terms and conditions of a software license agreement and the requirements for enforceability. The reverse engineering, decompiling or disassembling provision of the Louisiana SLEA was invalidated by the United States Court of Appeals for the Fifth Circuit ruling in Vault Corp. v. Quaid Software, Ltd., 847 F.2d 255 .
Atari Games Corp. v. Nintendo of America Inc., 975 F.2d 832, is a U.S. legal case in which Atari Games engaged in copyright infringement by copying Nintendo's lock-out system, the 10NES. The 10NES was designed to prevent Nintendo's video game console, the Nintendo Entertainment System (NES), from playing unauthorized game cartridges. Atari, after unsuccessful attempts to reverse engineer the lock-out system, obtained an unauthorized copy of the source code from the United States Copyright Office and used it to create its 10NES replica, the Rabbit. Atari then sued Nintendo for unfair competition and copyright misuse, and Nintendo responded that Atari had engaged in unfair competition, copyright infringement, and patent infringement.
Impression Products, Inc. v. Lexmark International, Inc., 581 U.S. ___ (2017), is a decision of the Supreme Court of the United States on the exhaustion doctrine in patent law in which the Court held that after the sale of a patented item, the patent holder cannot sue for patent infringement relating to further use of that item, even when in violation of a contract with a customer or imported from outside the United States. The case concerned a patent infringement lawsuit brought by Lexmark against Impression Products, Inc., which bought used ink cartridges, refilled them, replaced a microchip on the cartridge to circumvent a digital rights management scheme, and then resold them. Lexmark argued that as they own several patents related to the ink cartridges, Impression Products was violating their patent rights. The U.S. Supreme Court, reversing a 2016 decision of the Federal Circuit, held that the exhaustion doctrine prevented Lexmark's patent infringement lawsuit, although Lexmark could enforce restrictions on use or resale of its contracts with direct purchasers under regular contract law. Besides printer and ink manufacturers, the decision of the case could affect the markets of high tech consumer goods and prescription drugs.
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.
