"CryptMT is patent-pending. Its property owners are Hiroshima University and Ochanomizu University. However, the inventors had the following permission from the owners:
- CryptMT is free for non-commercial use.
- If CryptMT is selected as one of the recommendable stream ciphers by eSTREAM, then it is free even for commercial use.
This means that, if CryptMT Version 3 is one of the recommendable stream cihpers in the final report of May 2008 (planned by eSTREAM), then it can be used freely for any use, including commercial purposes.
On the other hand, if it did not stay in the final portfolio, then the IP owners will not make it free (but it is free for non-commercial use).
France Telecom beleives that the DECIM cipher is covered in part by a patent application in co-ownership between France Telecom and l'Universite de Caen Basse-Normandie (PCT/FT 04/0270, submitted August 2nd, 2004).
However, the inventors of DECIM wish that the DECIM cipher and the provided reference implementations are and remain freely available, and may be used for ayn purpose, including commercial exploitation, without restriction.
The Dragon algorithm is made freely available to all users, at their own risk
The submitters undertake to update the Ecrypt Stream Cipher project when necessary
We hereby explicitly release any intellectual property rights to Edon80 into the public domain.
The F-FCSR-H v2 and F-FCSR-16 stream ciphers are the intellectual property of their inventors. This work is supported by the Université de Limoges, the Centre National de la Recherche Scientifique and the Institut National de la Recherche en Informatique et Automatisme.
To our knowledge, the F-FCSR-H v2 and F-FCSR-16 stream ciphers are not based on any licensed, patented or otherwise legally restricted existing work.
The inventors wish that the F-FCSR ciphers and the provided reference implementations are and remains freely available, and may be used by anyone for any purpose, including commercial exploitation, without restriction.
The inventors also undertake the task to update the F-FCSR ciphers as required by the ECRYPT Stream Cipher project when necessary.
The Grain stream cipher is Copyright © 2005, Martin Hell, Thomas Johansson and Willi Meier. The Grain cipher is not based on any licence or patents.
We hereby grant anybody licence to use, copy, modify or distribute the Grain cipher under the following terms:
- You may not license or patent any intellectual work and/or product based on a copy or a modification of the Grain cipher. You may include the Grain cipher in a licensed or patented product but the Grain cipher must then be excluded from the license or patent in question.
- The copyright holders are not legally responsible for any damage caused by the use of any product based on the Grain cipher.
- You may not use, copy, modify, or distribute the Grain cipher except as expressly provided under this license. Any attempt otherwise to use, copy, modify or distribute the Grain cipher is void, and will automatically terminate your rights under this license.
This license can only be made void by the copyright holders and the ECRYPT NoE committee in agreement with the copyright holders.
The authors also undertake the task to update the Grain cipher as required by the ECRYPT NoE committee.
(The IPR statement also applies to Grain v1 and Grain-128).
The stream ciphers HC-128 and HC-256 are not patented and are royalty free. Anyone can use HC-128 and HC-256 free of charge. And I would like to update the ECRYPT Stream Cipher project when necessary.
Lex was put in public domain.
The designers of the algorithm do not claim any IPR over it, and make it freely available for any purpose. To the best of our knowledge no one else has any relevant IPR either. We will update the ECRYPT stream cipher project coordinators if we ever discover any.
The original IP statements about MICKEY and MICKEY-128 remain valid for the version 2.0 ciphers.
I, Joan Daemen, do hereby declare that to the best of my knowledge the practice of the algorithm I have submitted, known as MOUSTIQUE, may be covered by the following U.S. and/or foreign patents: none.
I do hereby declare that I am aware of no patent applications which may cover the practice of my submitted algorithm.
QUALCOMM Incorporated allows free and unrestricted use of any of its intellectual property required to exercise the primitive, including use of the provided source code. The designers are unaware of any intellectual property owned by other parties that would impact on the use of NLS. The designers undertake to inform the ECrypt Stream Cipher project of any changes regarding the intellectual property claims covering NLS.
The IPR statement applies to NLSv2 without change.
The Pomaranch cipher is copyrighted by the submitters. Noncommercial use is free of charge, and commercial use requires registration fees.

Rabbit was released in late 2008 into the public domain by Cryptico A/S (the company that designed the stream cipher), and may be used freely for any purpose. See here.
My policy is that Salsa20 is free for everyone to use. I am not aware of any patents or patent applications covering Salsa20. I will update the ECRYPT Stream Cipher project when necessary.
The Sosemanuk cipher and the provided reference implementations are knowledge arising from a joint work carried out under the X-CRYPT Project, supported by the Ministère de l'éducation Nationale, de la Recherche et de la Technologie, France. Thus, Axalto S.A., France Télécom, Cryptolog International, the Institut National de Recherche en Informatique et en Automatique, the Centre National de la Recherche Scientifique, the Université de Versailles Saint-Quentin-en-Yvelines and the École Normale Supérieure have joint ownership of the Sosemanuk cipher and its reference implementations.
To our knowledge, the Sosemanuk cipher is not based on any licensed, patented or otherwise legally restricted existing work. The inventors of Sosemanuk wish that the Sosemanuk cipher and the provided reference implementations are and remain freely available, and may be used by anyone for any purpose, including commercial exploitation, without restriction. In particular, the inventors did not -- and do not intend to -- license, patent or otherwise restrict neither the Sosemanuk algorithm, nor any part of it, nor any implementation of it.
The inventors also undertake the task to update the Sosemanuk cipher as required by the ECRYPT Stream cipher project when necessary.
To the author's knowledge Trivium is not covered by any patent. Trivium is also free available for any use.
