An amazing collection of the leading computer scientists in the world have joined together to stand with Google and against Oracle in the Oracle v. Google appeal about APIs, and they ask the court to affirm Judge William Alsup's decision that the Java APIs are not copyrightable. It's in an amicus brief [PDF] that EFF has just filed. Here's EFF's press release.
Amici are numerous individual computer scientists who believe the District Court correctly decided this case and who urge this Court to uphold that ruling. The signatories to this brief include some of the leading, pioneering scientists in the computer industry. They have invented or contributed to the authorship of numerous computer programs. They have joined this brief because they believe the District Court correctly rejected Oracle’s attempt to overextend copyright coverage in a manner irreconcilable with the purpose of copyright law and the nature of computer science.
As computer scientists, amici have relied on the open nature of APIs and the programs built on them to create and operate new software. Amici depend on APIs remaining open to sustain widespread compatibility standards used by startups and incumbents alike. Reversing the District Court would dangerously undermine the settled expectations of computer scientists who rely upon the open nature of APIs.
I believe this means that Oracle has now managed to dismay pretty much all the leaders in its chosen field. What kind of business sense does that make? Seriously, Oracle. Think this through, please. Bad karma lingers. This is your family. It's a family intervention.
The freedom to reimplement and extend existing APIs has been the key to competition and progress in the computer field—both hardware and software. It made possible the emergence and success of many robust industries we now take for granted—such as industries for mainframes, PCs, peripherals (storage, modems, printers, sound cards, etc.), workstations/servers, and so on—by ensuring that competitors could challenge established players and advance the state of the art.
Thus, excluding APIs from copyright protection has been essential to the development of modern computers and the Internet. For example, the widespread availability of diverse, cheap, and customizable personal computers owes its existence to the lack of copyright on the specification for IBM’s Basic Input/Output System (BIOS) for the PC. Companies such as Compaq and Phoenix reimplemented IBM’s BIOS without fear of copyright claims, making PC clones possible. And the open nature of APIs was essential to many modern computing developments, including those of operating systems such as UNIX, programming languages such as “C”, the Internet’s network protocols, and cloud computing.
The uncopyrightable nature of APIs spurs the creation of software that otherwise would not have been written. When programmers can freely reimplement or reverse engineer an API without the need to negotiate a costly license or risk a lawsuit, they can create compatible software that the interface’s original creator might never have envisioned or had the resources to create. Moreover, compatible APIs enable people to switch platforms and services freely, and to find software that meets their needs regardless of what browser or operating system they use. Without the compatibility enabled by the open nature of APIs, consumers could be forced to leave their data behind when they switch to a new service.
The freedom to reimplement APIs also helps rescue “orphan” software or data—systems whose creators have either gone out of business or abandoned their product in the marketplace. Government entities and non-profits are especially susceptible to the orphan programs problem as they often cannot afford to upgrade and are left using legacy technologies for years or decades.
When a popular computer platform or service shuts down, the ability to freely reimplement APIs protects the communities that rely on that software. This Court’s decision will determine whether or not APIs continue to remain open and thereby enable competition and innovation among software developers, and enable access to information and affordable technology for users. Should the Court reverse Judge Alsup’s well-reasoned opinion, it will hand Oracle and others the ability to monopolize any and all uses of systems that share their APIs. API creators would have veto power over any developer who wants to create a compatible program—regardless of whether she copies any literal code from the original API implementation. That, in turn, would upset the settled business practices that have enabled the American computer industries to flourish, and choke off many of the system’s benefits to consumers. Therefore, we respectfully request that this Court affirm the District Court’s decision.

I could go on, but could it be any clearer? What Oracle is trying to do has alienated the leaders in computer science, gray beards and the younger generation too. People who are experts in this field are standing up and letting the court know that what Oracle is trying to do should not be allowed to happen.
And it's about time the court heard from the folks who will be most directly impacted by the decision of the court, the ones who know what APIs are without a class on it, and who understand the real damage that will result if Oracle were to prevail. Oracle, please don't let David Boies place you in this position of playing a SCO-like role as he tries again to extend copyright. There are things more important than money. Even the scripture says that a good name is more precious than gold. Don't believe it? Think about how history will view Oracle's reputation because of this litigation.
Oracle responded sharply. "I guess everyone is having collective amnesia about the uncontroverted testimony that Android is not compatible with Java," said spokeswoman Deborah Hellinger.

system of technology we take for granted today depends on open interfaces. The more that individual companies can lock down communication standards that connect programs, the more information technology becomes fragmented, cutting users off from each other and from the benefits of computer innovation.
As Oracle’s lead trial lawyer noted before this dispute began, “compatibility in the personal computer arena has fostered innovation and competition—two critical policy objectives.” Michael Jacobs, Copyright and Compatibility, 30 Jurimetrics J. 91, 93 (1989-90). The uncopyrightability of APIs was key to the development of each major layer of computing that we use today, from the most fundamental to the cutting edge. The Court should consider this history carefully before changing the law and disrupting the settled expectations of the development community and of millions of programmer/developers.
emerge. Id. at 28–29. IBM-exclusive software, like the popular spreadsheet program Lotus 1-2-3, forced many users to buy IBM computers. Id. And although other computer manufacturers could run the same MS-DOS operating system that IBM used, many best-selling programs required complete hardware and Basic Input/Output System (BIOS) firmware3 compatibility as well, thus making the IBM model the de facto standard. Id. at 51–53; see, e.g., Stephen Satchell, The Corona ATP is Faster than the IBM PC AT, But it Has Flaws, InfoWorld, Jan. 1986, at 50 (using Microsoft Flight Simulator and Lotus 1-2-3 to test PC compatibility).
IBM PCs: the BIOS API, including its structure, sequence, and organization. Id. Once these firms developed their own BIOS firmware, they were able to produce cheaper, faster IBM-compatible computers, and market innovations like the first portable PC. Ferguson, supra, at 53–55; see also Compaq Computer Corporation: Portable Computer, Encyclopedia Britannica.4 With more computers and customers now available to them, software developers began to write and distribute more software than ever, innovating with new features and functionality and competing directly on price. The age of home computing began in earnest.
Copyrighted Works, Final Report 19 (1979) [hereinafter CONTU].5 Section 102(b), which denies copyright to any “process, system, or method of operation,” ensures that a programmer’s copyright protects his code, but does not protect the processes or methods that code enables a computer to perform. H.R. Rep. No. 94-1476 at 56–57, reprinted in 1976 U.S.C.C.A.N. 5659, 5670 [hereinafter House Rep.]; S. Rep. No. 94-473, at 54 (1975) (found under heading “Nature of copyright” addressing Section 102) [hereinafter Senate Rep.]. IBM owned the copyright on its BIOS source code, but that did not give it a monopoly on the system of commands the operating system used to communicate with the BIOS. Compaq and Phoenix were entitled to reimplement the BIOS interface as long as they did not copy any of IBM’s code. Cf. Lotus Dev. Corp. v. Borland Int’l, Inc., 49 F.3d 807, 810 (1st Cir. 1995) (holding that the menu structure and commands of Lotus’s interface comprised an uncopyrightable system or method of operation under § 102(b), and that Borland was free to reimplement them), aff’d by an equally divided Court, 516 U.S. 233 (1996). Notably, it is irrelevant under § 102(b) whether the API’s creator intends to keep its API proprietary or freely dedicate it to the public—either way, APIs are unprotectable methods of operation.
Many popular operating systems today reimplement the APIs of one of the earliest operating systems created. In 1969, Ken Thompson, Dennis Ritchie, and other computer scientists at AT&T Bell labs developed the first modern operating system. Heather J. Meeker, The Open Source Alternative at 3–4 (2008). They called it UNIX. Id. Predating the home computer by a decade, UNIX ran on large mainframe computers owned by corporations, universities, and the government. Id. At the time AT&T developed UNIX, the company was operating under a 1956 consent decree (the result of an antitrust suit) that forbade it from monetizing any project outside of telecommunications and special federal contracts. Milestones in AT&T History, ATT.com.6 To comply with the decree, AT&T licensed UNIX to any interested party for a nominal fee. Meeker, supra, at 4. Computer scientists embraced UNIX, making it the dominant operating system of its day. Id. Programmers shared their source code and programming innovations freely, developing and releasing new versions of the operating system. Id.
developers dissatisfied with available operating systems such as MS-DOS, Windows, and Apple’s system, along with UNIX users, reimplemented the UNIX API to run on a PC.7 Meeker, supra, at 6. They wanted to create a new operating system that would run software made for UNIX, but was also free of AT&T’s (or anyone’s) intellectual property, specifically a system comprising only free software. Id. The GNU project, together with the Finnish programmer Linus Torvalds, produced the Linux operating system, which shares the UNIX API—including its structure, sequences, and organization—but uses entirely original code. Id. Today, tens of millions of servers run Linux. Steven J. Vaughan-Nichols, How Many Linux Users Are There (Really)? Linux Planet (Feb. 18, 2009).8 Countless Internet-based services from Facebook to ATMs rely on Linux-based high-speed networking systems. Id. Because the API was open, it took a minimal amount of work to make pre-existing software run on subsequent systems.
programmer, rather than merely to the ‘writing’ expressing his ideas.” House Rep. at 56–57; Senate Rep. at 54. The law has thus allowed many individuals and companies to each provide its own code behind a UNIX interface, letting consumers adopt the right one to fit their needs.
Programs written in C use the C standard library to execute their functions and operate the computer on which they run—including tasks as basic as opening and closing files on the hard drive.
Limiting the ability to reimplement the C Standard Library would have likewise severely limited the range of systems on which C programs could run. Each operating system would require a unique set of libraries for C-based programs to call on, effectively creating a new, incompatible version of the language. Today, once a programmer learns C, he can write code that will run on any operating system that can run a reimplementation of the C standard library. API copyright would turn universal programming languages like C into narrow dialects, usable only on a specific operating system. Many innovative software projects would be restricted to a single operating system, or simply never get off the ground at all. Old programs would run the risk of becoming obsolete whenever a new operating system came into use, and new operating systems would be unable to take advantage of the thousands of existing C programs.
System designers and application programmers alike rely on the BSD sockets API as a de facto industry standard. See, e.g., Johnson M. Hart, Windows System Programming, ch. 12 (4th ed. 2010). Because the BSD sockets API is free of copyright, OS developers can redesign the implementation of the API to improve its efficiency, secure in the knowledge that consumers will be able to keep using all their programs. Network software specialists can write new implementations of the API, which can then be integrated into any operating system. Application programmers only have to write the networking section of their programs once and it will work on any operating system, making it cheaper and easier to make software available for multiple platforms.
Internet user clicks a link, her computer sends an HTTP command requesting the appropriate webpage from the server on which it is stored. Id. Because no one has ever asserted copyright in this protocol, anyone is free to write an implementation of the HTTP interface—meaning that his or her program can send and respond to HTTP requests.
HTTP was created by Tim Berners-Lee, the inventor of the Web, and developed as a standard in large part by the World Wide Web Consortium, an organization he founded and runs. Tim Berners-Lee, Biography, World Wide Web Consortium;18 Roy Fielding, et al., RCFC 2616: Hypertext Transfer Protocol—HTTP/1.1, Internet Engineering Task Force (June 1999).19 If interface specifications were copyrightable, Berners-Lee could have used copyright to determine which software and hardware manufacturers could use the Web. Mutually incompatible networking protocols would cause the Internet to fragment into isolated online communities incapable of exchanging information.
Microsoft’s Server Message Block (SMB) system nearly caused a similar kind of fragmentation to happen to local networks. The SMB network protocols govern local area networks, often used in homes and offices to allow local users to share files and printers. Richard Sharpe, Just What is SMB? Samba.org (Oct.
BSD sockets and network protocols are industry standard systems of communication. Although many programs reimplement these interfaces, § 102(b) ensures that such uses will not create copyright liability. See Lotus, 49 F.3d at 807. If the Court finds APIs subject to copyright, it could mean that even interfaces like HTTP might be copyrightable.
Modern cloud computing providers like Amazon Web Services rely on a reimplementation of one of the oldest APIs: the IBM BIOS. Cloud computing allows users to rent space and processing power on distant servers, accessible from anywhere in the world via the Internet. What is Cloud Computing?, Amazon Web Services.24 At their core, cloud computing clusters act as “virtual machines”—imitations of small computers being run on huge servers. See id.; see also Margaret Rouse, Definition: Virtual Machine (VM), SearchServerVirtualization (Oct. 2011).25 Virtual machines call the functions of the BIOS API just like physical computers, but they have no individual physical hardware. See id. Instead, a reimplementation of the BIOS API allows the server to answer the API calls of all the virtual machines running on it. See id.
Cloud computing providers also use an API to govern how their users can interact with their services. Amazon Web Services (AWS) and Eucalyptus Partner to Bring Additional Compatibility Between AWS and On-Premises IT Environments, Eucalyptus (March 22, 2012).26 Most providers rely on Amazon’s cloud services API to allow users to control and operate the cloud computers that they rent. The API is ineligible for copyright protection under § 102(b). Just as copyright law allowed Baker to compete with Selden to make the most useful book from Selden’s accounting system, § 102(b) ensures that companies like CloudStack and Eucalyptus can compete with Amazon to provide the best implementation of the cloud services API.
Source Cloud Wars, ZDNet (Apr. 12, 2012).28 Software developers can write programs capable of interacting with all three services, creating new ways for users to access and manipulate information spread out across the Internet.
If copyright allowed Amazon to monopolize its cloud storage API, Amazon would be able to use that power to lock in its users and cripple new competitors. Because businesses use custom software built around the cloud service provider’s API, switching to a cloud service provider with a different API would require rewriting their cloud software. The cost and disruption of doing so would mean that few businesses would be willing to leave their cloud service provider, leaving late entrants in the cloud service market to find it impossible to build a customer base and leaving consumers with less choice.
what new innovations will take advantage of widespread, compatible cloud services.
When programmers can freely employ any interface without the need to negotiate a costly license or risk a lawsuit, they may create compatible software that the interface’s original creator might never have envisioned or had the resources to create.
Copyrightable APIs would discourage this innovation by creating potential infringement liability for the mere act of writing a compatible program, even where no literal code is copied. The Copyright Act protects a programmer’s source code as creative expression, but does not cover the processes, systems, and methods of operation that code may employ to interface with other software. 17 U.S.C. § 102(b); see also House Rep. at 56-57; Senate Rep. at 54. In the Ninth Circuit, the “functional requirements for compatibility” between computer programs “are not protected by copyright” under § 102(b). Sega Enters., Ltd., v. Accolade, Inc., 977 F.2d 1510, 1522 (9th Cir. 1992); see also Sony Computer Ent’mt, Inc. v. Connectix Corp., 203 F.3d 596, 599–600 (9th Cir. 2000) (describing Sony’s Playstation BIOS as a “system interface procedure” that Connectix was entitled to reimplement under § 102(b)).
One straightforward and common reason to reimplement another programmer’s API is to make a program compatible with a different application or platform. Small companies and volunteer groups often undertake such projects, but heavy licensing fees or the threat of litigation over API copyright would hinder this work.
2005).31 If copyright law gave Microsoft a monopoly on the Windows API, Microsoft could demand licensing fees from Wine, or sue for statutory damages. Either outcome might lead to the Wine project shutting down permanently, preventing its users from running software they have legally purchased or licensed on their own computers.
A shared API is particularly important for supercomputers, because time on these machines is often limited. See e.g., Scheduling Policies and Limits, Ohio Supercomputers Center;34 PBS Information for Labs and the Lab Queue, Minnesota Supercomputing Institute.35 As a result, supercomputer users must write and test their programs on smaller computers and only use the supercomputer when they wish to run the program for research or experimental purposes. The program must work on both the smaller computer and the supercomputer, even though the two systems have different hardware and demands. BLAS and similar APIs provide a compatibility standard that allows supercomputers to run software written on other machines, as long as both machines have valid implementations of the same interfaces.
start. See National Research Council, supra, at 21. Moving to an incompatible new supercomputer is a hugely expensive and wasteful proposition. Id. If every supercomputer vendor had its own proprietary API, then research groups would find themselves “locked in” to the vendor they worked with at the start of their project. Supercomputer users would be unable to switch vendors to escape poor service or gain access to new technology without making their codebase useless. New vendors with improved supercomputer technology would be unable to attract customers, making it harder to successfully bring hardware innovations to market.
Developers reverse engineer APIs to write programs that add new features or provide new uses for online services. Roman Irani, The Curious Case of Unofficial APIs, Programmable Web (Nov. 15, 2011).36 For instance, many popular websites have companion mobile apps. Id. The website needs an API so that the app can communicate with it, even if that API is internal (i.e. unavailable to the public). Id. By monitoring traffic between the website and the app, a developer can reverse engineer the internal API, figure out its rules, and write extra code (called a “client wrapper”) to make it easier for outsiders to use.
infringed Instagram’s copyright, and become liable for statutory damages. If the fear of suit deterred people like Marohni! from helping developers produce compatible software or websites, Instagram may never have realized the full potential of its service.
Programmers frequently need to reimplement APIs in order to access data or other resources trapped in obsolete software. Software creators go bankrupt or stop supporting their creations, and the intellectual property in software is often bought and sold when startups are acquired or divisions of companies spin off or shut down. These characteristics create a class of “orphan software”, whose copyright owners are hard to find. Obsolete software becomes incompatible with modern computers and other modern software as platforms change. For owners of now-orphaned software, reimplementing an API associated with that software may be the only realistic way to reclaim the time and resources they have invested in it.
build compatible systems. An orphan program’s original implementation may be lost, obsolete, or inoperable, but any developer is free to build a new compatible program. Allowing copyright law to prevent an entire community of users and third-party developers from switching easily to another service would subvert the purpose of § 102(b).
Platform developers strive to create communities of users and developers around their platform. The ability to freely reimplement APIs protects these communities when the platform for their services is shut down.
usefulness of Delicious. Kristina Dell, Entrepreneurs Who Go It Alone—By Choice, Time (Oct. 24, 2011).42 Eventually Yahoo! sold Delicious, and many users decided to find a new place to go. Id.
A new social bookmarking site, Pinboard, offered itself up as a haven for former Delicious users. Id. By reimplementing the Delicious API, Pinboard allowed users to keep using their Delicious-based applications, but with Pinboard instead. Pinboard, supra. Pinboard was created by one man, Maciej Ceglowski, in his spare time. Dell, supra. If Ceglowski had to pay for an expensive license or risk copyright liability in order to reimplement the Delicious API, he probably wouldn’t have gone ahead with the project. The Delicious-based applications would have become useless.
As the above indicates, the open nature of APIs protects the investments of users in a platform or service as much as those of software developers. Twitter is a massively popular way to communicate with the world through microblogging. Some great uses of Twitter have come from add-on applications that call the Twitter API to provide additional services. Sickweather tracks Twitter and Facebook for people posting about being sick, and maps their comments so users can find out what illnesses are going around in their area.
How It Works, Sickweather.43 Flipboard lets users access all their social networks and regular news sources together. Flipboard, Flipboard.44 Third-party Twitter clients, programs that display Twitter feeds in different, user-friendly ways, are especially popular. Erick Schonfeld, The Top 21 Twitter Clients, TechCrunch (Feb. 19, 2009).45 There are so many Twitter-based applications and Twitter clients that Twitter’s own developers could not have created and implemented all of them. In fact, Twitter has not built native apps for some hardware devices, and Twitter clients are the only Twitter apps available for users of those devices. John McDermott, App Developers Shun Microsoft’s Surface, Ad Age (Dec. 4, 2012).46 If Twitter were to go out of business or stop supporting these applications, many users would lose access to their favorite applications. If this happened, a new competitor could come into the market and support those applications by reimplementing the Twitter API.
Government entities and non-profits are especially susceptible to the orphan programs problem since their tight budgets often force them to use outdated technology. One of our signatories, Jeremiah Flerchinger, is a developmental engineer with over eight years of service in the Department of Defense and, later, with a machine-tool company. The National Aeronautics and Space Administration (NASA) sought to repurpose old manufacturing robots for a new project, and asked Flerchinger’s company to manufacture and program updated memory chips to store the robots’ new instructions. Configuring firmware to put on the chips required using obsolete software that wouldn’t run on modern computers. Flerchinger reimplemented the software’s API, creating modern software that could fulfill the same functions and work alongside old machines that had the same API hard-coded into their electronics.
If APIs were copyrightable, Flerchinger’s company would have needed a license to reimplement that software’s API. Assuming they could afford it, finding the right person to grant permission for a reimplementation would have been extremely difficult. If Flerchinger’s company couldn’t control its liability, they would not have been able to reimplement the API and complete their contract. Copyright on the API of obsolete software could have forced NASA to spend its limited funding on replacing its perfectly functional manufacturing robots. In these days of budget cuts and the “sequester,” such unnecessary spending should be discouraged, not encouraged, by this Court.
The freedom to reimplement and extend existing APIs has undoubtedly led to robust software and hardware industries, but also to an explosion of technological advances that do more than merely increase companies’ bottom lines. They open the world for the sharing of information, increased communication, and technological advances that could have never been contemplated.

App. P. 29(c)(5), Google’s general contributions to EFF were not intended to fund preparing or submitting this brief.
