Copyleft definition
Copyleft means a licensing model that permits anyone to use, modify or redistribute software, subject to a condition of use, modification, and/or distribution of such software, whereby such software and/or any other software incorporated into such software, derived from or distributed with such software be (i) disclosed or distributed in source code form to the public, (ii) licensed to the public for the purpose of making derivative works or (iii) re-distributed to anyone at no charge.
Copyleft means a form of licensing that grants to any person the rights to freely use, modify, copy and distribute copies and/or modified versions of a particular program (open source software), provided that the same rights are preserved in any derivative works of such program. GNU General Public License is an example of copyleft licensing.
Copyleft means Open Source license terms that require that the same conditions set forth in such license be included in any derivative works of such Open Source. "Share-Alike Database" means Open Source license conditions that require that the same conditions set forth in such license be included in adapted versions of this database.

Copyleft means that modifications of the licensed work must also be distributed under the same license terms. Copyleft licenses are different from the more permissive open-source licenses that allow derivative works to be sublicensed, or released under a different license, including in some cases proprietary ones. The warranty feature grants distributors the right to place some type of warranty, or a time limit, on either the software or services related to the software. A patent clause is either a patent grant or a patent retaliation clause. A patent grant requires that distributors give rights to use contributor's patents for all functionality of the software so that, when someone contributes to a software package, he or she cannot later sue others for using the software. A retaliation clause essentially seeks to protect the holder from any patent aggression. A trademark clause states that distributors do not have the right to use the licensor’s name or symbol that represents the author or the product. Finally, a no-promotion feature means that distributors cannot use the name of the software or the author(s) for promotion purposes.
Copyleft refers to licenses that allow derivative works but require them to use the same license as the original work. For example, if a software is written and release under the GNU General Public License (a widely-used copyleft license), and then someone else modifies that software and distributes their modified version, the modified version must be licensed under the GNU GPL too — including any new code written specifically to go into the modified version. Both the original and the new work are open source; the copyleft license simply ensures that property is perpetuated to all downstream derivatives. Most copyleft licenses are open source, but not all open source licenses are copyleft. When an open source license is not copyleft, that means software released under that license can be used as part of programs distributed under other licenses, including proprietary (non-open-source) licenses. Copyleft provisions apply only to actual derivatives, that is, cases where an existing copylefted work was modified. ▇▇▇▇▇▇ distributing a copyleft work alongside a non-copyleft work does not cause the latter to fall under the copyleft terms. In the end, it is necessary to understand if it is possible to write proprietary code that links to a shared library that is open source. Sometimes it is possible; it depends on the open source license. Authors often permit users to do this, so most shared libraries are licensed under a permissive license or one that allows linking under certain circumstances (e.g., the LGPL1). A 1 GNU LESSER GENERAL PUBLIC LICENSE available at ▇▇▇▇://▇▇▇▇▇▇▇▇▇▇.▇▇▇/licenses/LGPL-3.0. very small number of libraries use the GPL2, which only allows linking with proprietary works if the licensor grants an explicit exception. Thus, it is advisable to check the licenses that the program links to. The community expects that all code linked to GPL code will be licensed under the GPL, even if the link is made at runtime using a shared library. With particular regard to the open source software deployed by partners, these can be identified in the following licenses:
