However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License.
Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License.

For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation including a cross-claim or counterclaim in a lawsuit alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either 1 cause the Corresponding Source to be so available, or 2 arrange to deprive yourself of the benefit of the patent license for this particular work, or 3 arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients.
You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license a in connection with copies of the covered work conveyed by you or copies made from those copies , or b primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.

The Jahia Community Source License is not a free software license. Use of the source code is limited to research purposes.
This is the license of the original implementation of the JSON data interchange format. The restriction might be unenforcible, but we cannot presume that. Thus, the license is nonfree. One reason for this is that it required that all changes be sent to the developer. The lha license must be considered nonfree because it is so vague that you cannot be sure what permissions you have. This license does not permit commercial distribution, and only allows commercial use under certain circumstances.
Free software development depends on combining code from third parties, and the NASA license doesn't permit this.
We urge you not to use this license. In addition, if you are a United States citizen, please write to NASA and call for the use of a truly free software license. This is not a free software license, because it requires sending every published modified version to a specific initial developer. The Peer-Production License is not a free software license because it restricts who can redistribute the program and for what purpose.
It also does not give anyone permission to run the program. The PPL has several provisions designed specifically for artistic performances, and we have nothing against its use for art works; however, people reportedly advocate its use for software too.
The PPL should not be used for software, manuals, or other works that ought to be free. The Personal Public License Version 3a is a nonfree license because it denies some users organizations, governments, businesses the four freedoms. The license of PINE is not a free software license because it mostly prohibits the distribution of modified versions. It also restricts the media that can be used for selling copies. Please note that a successor to Pine, Alpine, is released under the Apache License, version 2.
This is not a free software license; it lacks essential freedoms such as the right to make and use private changes. Of course you should not use this license, and we urge you to avoid any software that has been released under it. A detailed discussion of this license is also available. However, a further license change in made Plan 9 free software.
The Reciprocal Public License is a nonfree license because of three problems. It puts limits on prices charged for an initial copy. It requires notification of the original developer for publication of a modified version. It requires publication of any modified version that an organization uses, even privately. This is not a free software license because it does not allow commercial distribution of a modified version.
Thankfully, starting from version 5. This is not a free software license because it does not allow commercial redistribution.
In addition, condition 4 substantively restricts the functionality of modified versions. Newer versions Scratch software are distributed under the GNU GPL, but some of those newer version we do not recommend, because they depend on the proprietary software, Adobe Air. The original Squeak license, as applied to software, is not a free software license because it requires all users in whatever country to obey US export control laws.
As applied to fonts, it also does not permit modification. In addition, it has a requirement for users to indemnify the developer, which is enough to make many users think twice about using it at all. Recent versions of Squeak from 4. This is not a free software license; it lacks essential freedoms such as publication of modified versions.
The license prohibits redistribution, prohibits commercial use of the software, and can be revoked. This license requires all recipients to proactively help the licensor enforce its trademarks.
This is an unreasonable condition to place on users' rights, so the license is nonfree. However, our judgment of it is not based on that. This license is nonfree for several reasons. It says that if you don't understand the license you may not use the program.
It puts conditions on allowing others to run your copy. There are other points in the license which seem perhaps unacceptable, and in our uncertainty about them we delayed in posting our evaluation. We have posted it now to explain why we do not mourn the demise of Truecrypt.
There are free programs that do the same job. The University of Utah Research Foundation Public License is a nonfree license because it does not allow commercial redistribution. It also purports to restrict commercially running the software and even commercially giving consultation about it. Those restrictions are probably not legally enforceable under US copyright law, but they might be in some countries; even asserting them is outrageous.
The use of this license by the University of Utah exemplifies a dangerous trend for universities to restrict knowledge rather than contributing it to the public. If a university tries to impose a license like this on the software you are writing, don't give up hope. With persistence and firmness, and some forethought, it is possible to prevail over money-grabbing university administrators. The license prohibits distribution for a fee, and that makes it impossible for the software to be included in the many CD-ROM free software collections that are sold by companies and by organizations.
There may be another problem in section 2a, but a word seems to be missing there, so it is hard to be sure what meaning is really intended. The following licenses qualify as free documentation licenses.

It is also suitable for other kinds of useful works such as textbooks and dictionaries, for instance. This license can be used as a free documentation license. But if either of the options is invoked, the license becomes nonfree. Likewise, if you use this license without either of the options to make your manual free, someone else might decide to imitate you, then change his or her mind about the options thinking that that is just a detail; the result would be that his or her manual is nonfree.
Thus, while manuals published under this license do qualify as free documentation if neither license option was used, it is better to use the GNU Free Documentation License and avoid the risk of leading someone else astray. Please note that this license is not the same as the Open Content License. It is worth spelling their names in full to make sure people understand what you say.

This license does not qualify as free, because there are restrictions on distributing modified versions. We recommend you do not use this license for documentation. We also recommend the GNU FDL for dictionaries, encyclopedias, and any other works that provide information for practical use. CC0 is a public domain dedication from Creative Commons.
A work released under CC0 is dedicated to the public domain to the fullest extent permitted by law. If that is not possible for any reason, CC0 also provides a lax, permissive license as a fallback. If you want to release your non-software work to the public domain, we recommend you use CC0. For works of software it is not recommended, as CC0 has a term expressly stating it does not grant you any patent licenses. Because of this lack of patent grant, we encourage you to be careful about using software under this license; you should first consider whether the licensor might want to sue you for patent infringement.
If the developer is refusing users patent licenses, the program is in effect a trap for users and users should avoid the program. This is a non-copyleft free license that is good for art and entertainment works, and educational works. When you see such a statement in a work, please ask the author to change the work to state clearly and visibly which of the Creative Commons license it uses.
This is a copyleft free license that is good for artistic and entertainment works, and educational works. Like all CC licenses, it should not be used on software. This is a free and copyleft license meant for general data.
This is a free and copyleft license meant for artistic works. It permits commercial distribution, as any free license must.
It is a copyleft license because any larger work that includes part of the work you received must be released, as a whole, either under the same license or under a similar license that meets stated criteria. This is a free and copyleft license meant for data. It makes inconvenient requirements about signing contracts which try to create an effect like copyleft for data that is not copyrightable, so we don't recommend using it; however, there is no reason to avoid using data released this way.
The licenses below apply to an instantiation of a design in a computer file, not the artistic design. As far as we know, an implementation of a design is always copyrightable.
The legal status of the artistic design is complex, and varies by jurisdiction. However, note that it does not permit embedding the font in a document unless that document is also licensed under the GPL. If you want to allow this, use the font exception. Its normal use is for fonts, and in that use, the incompatibility does not cause a problem. Depending on how it is used, it may be free or not. Some GNU programs have additional permissions or special exceptions to specific terms in one of the main licenses.

Legally speaking, the original English version of the licenses is what specifies the actual distribution terms for GNU programs and others that use them. But to help people better understand the licenses, we give others permission to publish unofficial translations into other languages, provided that they follow our regulations for unofficial translations.
The FSF does not approve license translations as officially valid. The reason is that checking them would be difficult and expensive needing the help of bilingual lawyers in other countries. Even worse, if an error did slip through, the results could be disastrous for the whole free software community.
As long as the translations are unofficial, they can't do any legal harm. To underscore the fact that these translations are not officially valid, we do not publish translations.
To make that clear, we don't post them on gnu. It used to be and for a few pages still is :. Verbatim copying and distribution of this entire article are permitted worldwide, without royalty, in any medium, provided this notice is preserved. Retention of weblinks in both hyperlinked and non-hyperlinked media as notes or some other form of printed URL in non-HTML media is required. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either 1 cause the Corresponding Source to be so available, or 2 arrange to deprive yourself of the benefit of the patent license for this particular work, or 3 arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license a in connection with copies of the covered work conveyed by you or copies made from those copies , or b primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
If conditions are imposed on you whether by court order, agreement or otherwise that contradict the conditions of this License, they do not excuse you from the conditions of this License.
If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.
Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode:.
If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. We defend the rights of all software users. There are also other ways to contact the FSF. The precise terms and conditions for copying, distribution and modification follow. Source Code. The Corresponding Source for a work in source code form is that same work. Basic Permissions. Conveying Verbatim Copies. Conveying Modified Source Versions.
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: a The work must carry prominent notices stating that you modified it, and giving a relevant date. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged.
This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. Conveying Non-Source Forms. 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 Convey the object code in, or embodied in, a physical product including a physical distribution medium , accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
