We hold these assets to defend free software from efforts to turn free software proprietary. Every year we collect thousands of copyright assignments from individual software developers and corporations working on free software. We register these copyrights with the US copyright office and enforce the license under which we distribute free software — typically the GNU General Public License. Such a provision ensures that both it, and the entire GPL, is enforceable in any jurisdiction, regardless of any particular law regarding the permissibility of certain warranty disclaimers.
There are many types of warranties, and in some jurisdictions some of them cannot be disclaimed. Again, some have argued the GPL is unenforceable in some jurisdictions because its limitation of liability is impermissibly broad. This chapter discusses the text of GPLv3. Ultimately, RMS was the primary author of GPLv3, but he listened to feedback from all sorts of individuals and even for-profit companies.
Overall, the changes made in GPLv3 admittedly increased the complexity of the license. Obsession for concision should never trump software freedom. However, one important goal that is often lost in the discussion of policy minutia is a rather simple but important issue. In particular, the FSF sought to ease interpretation of GPL in other countries by replacement of USA-centric 1 copyright phrases and wording with neutral terminology rooted in description of behavior rather than specific statute.
As can be seen in the section-by-section discussion of GPLv3 that follows, nearly every section had changes related to issues of internationalization. Most licenses define terms up-front. However, the GPL was always designed both as a document that should be easily understood both by lawyers and by software developers: it is a document designed to give freedom to software developers and users, and therefore it should be comprehensible to that constituency.
Interestingly enough, one coauthor of this tutorial who is both a lawyer and a developer pointed out that in law school, she understood defined terms more quickly than other law students precisely because of her programming background. As such, adding a defined terms section was not terribly problematic for developers, and thus GPLv3 adds one. Most of these defined terms are somewhat straightforward and bring forward better worded definitions from GPLv2.
Herein, this tutorial discusses a few of the new ones. Even though differently-labeled concepts corresponding to the derivative work are recognized in all copyright law systems, these counterpart concepts might differ to some degree in scope and breadth from the USA derivative work. The new definitions returns to the common elements of copyright law. Copyright holders of works of software have the exclusive right to form new works by modification of the original — a right that may be expressed in various ways in different legal systems.
GPLv3 uses a common license drafting technique of building upon simpler definitions to make complex ones. Next, to avoid locking GPLv3 into specific copyright statues, the GPLv3 defines two terms that are otherwise exotic to the language of international copyright.
Indeed, even within a single country and language, the term distribution may be ambiguous; as a legal term of art, distribution varies significantly in meaning among those countries that recognize it. Thus, propagation is defined by behavior, and not by categories drawn from some particular national copyright statute. Conveying includes activities that constitute propagation of copies to others.
As with the definition of propagate, GPLv3 thus addresses transfers of copies of software in behavioral rather than statutory terms. Usually, conveying is the activity that triggers most of the other obligations of GPLv3.
Also, experience with GPLv2 and other licenses that grant software freedom showed throughout the s that the scope of types of notices that need preservation upon conveyance were more broad that merely the copyright notices. The Appropriate Legal Notice definition consolidates the material that GPLv2 traditionally required preserved into one definition. Object code is not restricted to a narrow technical meaning and is understood broadly to include any form of the work other than the preferred form for making modifications to it.
The GPL, as always, seeks to ensure users are truly in a position to install and run their modified versions of the program; the CCS definition is designed to be expansive to ensure this software freedom.
Early drafts of GPLv3 included those requirements in the definition of CCS; however, given that the lock-down issue only comes up in distribution of object code, it is more logical to place those requirements with the parts of GPLv3 dealing directly with object code distribution.
Many code generators, preprocessors and take source code as input and sometimes even have output that is still source code. Source code should always be whatever the original programmer preferred to modify. Specifically, the right to convey source code that does not compile, does not work, or otherwise is experimental in-progress work is fully permitted, provided that no object code form is conveyed as well. One always has the right to modify a source code work by deleting any part of it, and there can be no requirement that free software source code be a whole functioning program.
The previous section skipped over one part of the CCS definition, the so-called system library exception. The system library exception is designed to allow copylefted software to link with these libraries when prohibition of that linking would hurt software freedom more than it would hurt proprietary software.
The system library exception has two parts. However, in isolation, a would be too permissive, as it would sometimes allow distributors to evade important GPL requirements. Part b reigns in a. Specifically, b specifies only a few functionalities that a system library may provide and still qualify for the exception.
The goal is to ensure system libraries are truly adjunct to a major essential operating system component, compiler, or interpreter. The more low-level the functionality provided by the library, the more likely it is to be qualified for this exception. Admittedly, the system library exception is a frequently discussed topic of obsessed GPL theorists. The amount that has been written on the system library exception both the GPLv2 and GPLv3 versions of it , if included herein, could easily increase this section of the tutorial to a length greater than all the others.
Like any exception to the copyleft requirements of GPL, would-be GPL violators frequently look to the system library exception as a potential software freedom circumvention technique. However, the usual style of improvements found in GPLv3 are found here as well. Under the copyright laws of some countries, it may be necessary for a copyright license to include an explicit provision setting forth the duration of the rights being granted.
In other countries, including the USA, such a provision is unnecessary but permissible. These rights are compatible with, and not in conflict with, the freedoms that the GPL seeks to protect, and the GPL cannot and should not restrict them. However, note that sadly to some copyleft advocates the unlimited freedom to run is confined to the unmodified Program.
However, the client can only exercise this control over its own copyrighted changes to the GPL-covered program. The parts of the program it obtained from other contributors must be provided to the contractor with the usual GPL freedoms. By making the limits on this provision very narrow, GPLv3 ensures that, in all other cases, contractor gets the full freedoms of the GPL that they deserve. Whether GPLv2 permits these activities is not clear and may depend on variations in copyright law in different jurisdictions.
The practices seem basically harmless, so FSF decided to make it clear they are permitted. This provision ensures that GPL enforcement is always by the copyright holder.
Usually, sublicensing is regarded as a practical convenience or necessity for the licensee, to avoid having to negotiate a license with each licensor in a chain of distribution. The issues of DRM, device lock-down and encryption key disclosure were the most hotly debated during the GPLv3 process. Specifically, GPLv3 introduced provisions that respond to the growing practice of distributing GPL-covered programs in devices that employ technical means to restrict users from installing and running modified versions.
This practice thwarts the expectations of developers and users alike, because the right to modify is one of the core freedoms the GPL is designed to secure. However, these measures are alike in one basic respect. They all employ technical means to turn the system of copyright law where the powers of the copyright holder are limited exceptions to general freedom into a virtual prison, where everything not specifically permitted is utterly forbidden.
GPLv2 did not address the use of technical measures to take back the rights that the GPL granted, because such measures did not exist in , and would have been irrelevant to the forms in which software was then delivered to users. Such technologies present no obstacles to software freedom and the goals of copyleft.
The public GPLv3 drafting process sought to balance these positions of copyleft advocates with various disparate views of the larger Free-Software-using community. The compromises made were ultimately quite reasonable. In addition, the distributor is required to keep intact all license notices, including notices of such additional terms. Finally, there is no harm in explicitly pointing out what ought to be obvious: that those who convey GPL-covered software may offer commercial services for the support of that software.
In particular, the modified files themselves need no longer be marked. The intent and scope is the same as was intended in GPLv2. Physical products include embedded systems, as well as physical software distribution media such as CDs. Note that this is a substantial narrowing of requirements of offer fulfillment, and is a wonderful counterexample to dispute claims that the GPLv3 has more requirements than GPLv2.
As before, the offer must remain valid for at least three years. This is a reasonable and appropriate requirement; a distributor should be prepared to provide source code if he or she is prepared to provide support for other aspects of a physical product. This wording also permits a distributor to offer a third party access to both object code and source code on a single network portal or web page, even though the access may include links to different physical servers.
This codifies formally the typical historical interpretation of GPLv2. If distributors convey the object code gratis, distributors must likewise make CCS available without charge. Here the requirement is only that each peer be effectively informed of the location of the source code on a server as above. In particular, Decentralized peer-to-peer file sharing present a challenge to the unidirectional view of distribution that is implicit in GPLv2 and initial drafts of GPLv3.
In peer-to-peer distribution systems, participants act both as transmitters and recipients of blocks of a particular file, but they perceive the experience merely as users and receivers, and not as distributors in any conventional sense. At any given moment of time, most peers will not have the complete file. This wording might be interpreted to permit peer-to-peer distribution of binaries if they are packaged together with the CCS, but such packaging is impractical, for at least three reasons.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December , or similar laws prohibiting or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage.
A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term regardless of how the transaction is characterized , the Corresponding Source conveyed under this section must be accompanied by the Installation Information.
A code under this license owned by FSF? Or it's my code if I'm author. Is it valid header for a file to save my copyright. Beware the iHandcuffs". The New York Times. Retrieved 26 May September 18, Long story short, being on the Free Software Foundation's high priority list really doesn't mean much with some of these "important" projects not even being actively developed or even discussed. Most of the projects are basically not going anywhere. Many of them at the time were not really advancing in their goals, haven't had releases in a while, or coding hasn't even started.
It's been more than a half-year and still there's no significant work towards clearing many of projects from the FSF list. Retrieved 4 February Retrieved 22 March February Those documents further indicate that the annual meeting occurred in August; usually, new directors are elected at annual meetings.
However, minor conditions must be followed that ensures the rights of GPL software is not restricted. The following is a quote from the gnu. An "aggregate" consists of a number of separate programs, distributed together on the same CD-ROM or other media. The GPL permits you to create and distribute an aggregate, even when the licenses of the other software are non-free or GPL-incompatible. The only condition is that you cannot release the aggregate under a license that prohibits users from exercising rights that each program's individual license would grant them.
Where's the line between two separate programs, and one program with two parts? This is a legal question, which ultimately judges will decide. We believe that a proper criterion depends both on the mechanism of communication exec, pipes, rpc, function calls within a shared address space, etc.
If the modules are included in the same executable file, they are definitely combined in one program. If modules are designed to run linked together in a shared address space, that almost surely means combining them into one program. By contrast, pipes, sockets and command-line arguments are communication mechanisms normally used between two separate programs. So when they are used for communication, the modules normally are separate programs.
But if the semantics of the communication are intimate enough, exchanging complex internal data structures, that too could be a basis to consider the two parts as combined into a larger program. The FSF thus draws the line between "library" and "other program" via 1 "complexity" and "intimacy" of information exchange, and 2 mechanism rather than semantics , but resigns that the question is not clear-cut and that in complex situations, case law will decide.
There was no lawsuit filed for this violation. After a preliminary hearing before Judge Patti Saris on 27 February , the parties entered settlement talks and eventually settled. This was a problematic stand for them, as they had distributed Linux and other GPL'ed code in their Caldera OpenLinux distribution, and there is little evidence that they had any legal right to do so except under the terms of the GPL.
In July , the German court confirmed this injunction as a final ruling against Sitecom. This ruling was important because it was the first time that a court had confirmed that violating terms of the GPL could be a copyright violation and established jurisprudence as to the enforceability of the GPL version 2 under German law. The suit was dismissed in March , on the grounds that Wallace had failed to state a valid antitrust claim; the court noted that "the GPL encourages, rather than discourages, free competition and the distribution of computer operating systems, the benefits of which directly pass to consumers".
This argument was considered without ground. On 6 September , the gpl-violations. In late , the BusyBox developers and the Software Freedom Law Center embarked upon a program to gain GPL compliance from distributors of BusyBox in embedded systems , suing those who would not comply.
Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software and charge for them if you wish , that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software.
For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software.
The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary.
