modifications to the software be distributed under the CeCILL, but it makes no claim to work that executes in "separate address spaces", which may be licensed under terms of the licensee's choice. It does not grant a patent license (as some other common open-source licenses do), but rather includes a promise by the licensor not to enforce any patents it owns. In
Article 9.4, the licensor agrees to provide "technical and legal assistance" if litigation regarding the software is brought against the licensee, though the extent of the assistance "shall be decided on a case-by-case basis...pursuant to a memorandum of understanding".

also working in domains like military and defense systems) also gives much more security than using the GPL alone, as the license is supported officially by a government which is a full member of WIPO, and by an enforceable law. This also means that all international treaties related to the protection of intellectual rights do apply to CeCILL-licensed products, and so they are enforceable by law in all countries that signed any of the international treaties protected by WIPO. However, this also leaves open the possibility that the French government will make a future version of the CeCILL unfree and restricted.

producing an authentic translation in any international court will be lower with the help of a second authentic reference text. The second difference is that the reference to the GNU General Public
License, with which CeCILL v2 is now fully compatible, is explicitly defined precisely using its exact title and the exact name of the Free Software Foundation, to avoid all possible variations of the terms of the GPL v2. Some additional definitions were added to more precisely define the terms with less ambiguity. With these changes, the CeCILL is now fully enforceable according to

Although the three CeCILL licenses were developed and used for strategic French research systems (in the domain of defense, space launching systems, medical research, meteorology/climatology, and various domains of fundamental or applied physics), they are made to be usable also by the general public

The disclaimers of warranty and liability are written in a manner different from other common open-source licenses to comply with French law. The CeCILL does not preclude the licensor from offering a warranty or technical support for its software, but requires that such services be negotiated in a

Without these licenses, such systems could not have been built and used, and protected legally against various international patent claims. Due to the huge cost of these French strategic systems, a very strong licensing scheme was absolutely necessary to help protecting these investments against

The most notable difference in CeCILL v2 is the fact that the
English text was approved not as a draft translation (as in CeCILL v1) but as an authentic text, in addition to the equally authentic French version. This makes the CeCILL license much easier to enforce internationally, as the cost of

The CeCILL grants users the right to copy, modify, and distribute the licensed software freely. It defines the rights as passing from the copyright holder to a "Licensor", which may be the copyright holder or a further distributor, to the user or "Licensee". Like the GPL, it requires that

Note that CeCILL v1 already allowed replacing a CeCILL v1 license with CeCILL v2, so all software previously licensed with CeCILL v1 in 2004 can be licensed with CeCILL v2, with legal terms enforceable as authentic not only in French but in
English too.

The CeCILL license is approved as a "Free
Software" license by the FSF with which the CeCILL project founders have worked. Since version 2.1, CeCILL is also approved by the Open Source Initiative as an "Open Source" license.
