Creative Commons Legal Code |
||||
|
||||
CC0 1.0 Universal |
||||
|
||||
CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE |
||||
LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN |
||||
ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS |
||||
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES |
||||
REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS |
||||
PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM |
||||
THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED |
||||
HEREUNDER. |
||||
|
||||
Statement of Purpose |
||||
|
||||
The laws of most jurisdictions throughout the world automatically confer |
||||
exclusive Copyright and Related Rights (defined below) upon the creator |
||||
and subsequent owner(s) (each and all, an "owner") of an original work of |
||||
authorship and/or a database (each, a "Work"). |
||||
|
||||
Certain owners wish to permanently relinquish those rights to a Work for |
||||
the purpose of contributing to a commons of creative, cultural and |
||||
scientific works ("Commons") that the public can reliably and without fear |
||||
of later claims of infringement build upon, modify, incorporate in other |
||||
works, reuse and redistribute as freely as possible in any form whatsoever |
||||
and for any purposes, including without limitation commercial purposes. |
||||
These owners may contribute to the Commons to promote the ideal of a free |
||||
culture and the further production of creative, cultural and scientific |
||||
works, or to gain reputation or greater distribution for their Work in |
||||
part through the use and efforts of others. |
||||
|
||||
For these and/or other purposes and motivations, and without any |
||||
expectation of additional consideration or compensation, the person |
||||
associating CC0 with a Work (the "Affirmer"), to the extent that he or she |
||||
is an owner of Copyright and Related Rights in the Work, voluntarily |
||||
elects to apply CC0 to the Work and publicly distribute the Work under its |
||||
terms, with knowledge of his or her Copyright and Related Rights in the |
||||
Work and the meaning and intended legal effect of CC0 on those rights. |
||||
|
||||
1. Copyright and Related Rights. A Work made available under CC0 may be |
||||
protected by copyright and related or neighboring rights ("Copyright and |
||||
Related Rights"). Copyright and Related Rights include, but are not |
||||
limited to, the following: |
||||
|
||||
i. the right to reproduce, adapt, distribute, perform, display, |
||||
communicate, and translate a Work; |
||||
ii. moral rights retained by the original author(s) and/or performer(s); |
||||
iii. publicity and privacy rights pertaining to a person's image or |
||||
likeness depicted in a Work; |
||||
iv. rights protecting against unfair competition in regards to a Work, |
||||
subject to the limitations in paragraph 4(a), below; |
||||
v. rights protecting the extraction, dissemination, use and reuse of data |
||||
in a Work; |
||||
vi. database rights (such as those arising under Directive 96/9/EC of the |
||||
European Parliament and of the Council of 11 March 1996 on the legal |
||||
protection of databases, and under any national implementation |
||||
thereof, including any amended or successor version of such |
||||
directive); and |
||||
vii. other similar, equivalent or corresponding rights throughout the |
||||
world based on applicable law or treaty, and any national |
||||
implementations thereof. |
||||
|
||||
2. Waiver. To the greatest extent permitted by, but not in contravention |
||||
of, applicable law, Affirmer hereby overtly, fully, permanently, |
||||
irrevocably and unconditionally waives, abandons, and surrenders all of |
||||
Affirmer's Copyright and Related Rights and associated claims and causes |
||||
of action, whether now known or unknown (including existing as well as |
||||
future claims and causes of action), in the Work (i) in all territories |
||||
worldwide, (ii) for the maximum duration provided by applicable law or |
||||
treaty (including future time extensions), (iii) in any current or future |
||||
medium and for any number of copies, and (iv) for any purpose whatsoever, |
||||
including without limitation commercial, advertising or promotional |
||||
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each |
||||
member of the public at large and to the detriment of Affirmer's heirs and |
||||
successors, fully intending that such Waiver shall not be subject to |
||||
revocation, rescission, cancellation, termination, or any other legal or |
||||
equitable action to disrupt the quiet enjoyment of the Work by the public |
||||
as contemplated by Affirmer's express Statement of Purpose. |
||||
|
||||
3. Public License Fallback. Should any part of the Waiver for any reason |
||||
be judged legally invalid or ineffective under applicable law, then the |
||||
Waiver shall be preserved to the maximum extent permitted taking into |
||||
account Affirmer's express Statement of Purpose. In addition, to the |
||||
extent the Waiver is so judged Affirmer hereby grants to each affected |
||||
person a royalty-free, non transferable, non sublicensable, non exclusive, |
||||
irrevocable and unconditional license to exercise Affirmer's Copyright and |
||||
Related Rights in the Work (i) in all territories worldwide, (ii) for the |
||||
maximum duration provided by applicable law or treaty (including future |
||||
time extensions), (iii) in any current or future medium and for any number |
||||
of copies, and (iv) for any purpose whatsoever, including without |
||||
limitation commercial, advertising or promotional purposes (the |
||||
"License"). The License shall be deemed effective as of the date CC0 was |
||||
applied by Affirmer to the Work. Should any part of the License for any |
||||
reason be judged legally invalid or ineffective under applicable law, such |
||||
partial invalidity or ineffectiveness shall not invalidate the remainder |
||||
of the License, and in such case Affirmer hereby affirms that he or she |
||||
will not (i) exercise any of his or her remaining Copyright and Related |
||||
Rights in the Work or (ii) assert any associated claims and causes of |
||||
action with respect to the Work, in either case contrary to Affirmer's |
||||
express Statement of Purpose. |
||||
|
||||
4. Limitations and Disclaimers. |
||||
|
||||
a. No trademark or patent rights held by Affirmer are waived, abandoned, |
||||
surrendered, licensed or otherwise affected by this document. |
||||
b. Affirmer offers the Work as-is and makes no representations or |
||||
warranties of any kind concerning the Work, express, implied, |
||||
statutory or otherwise, including without limitation warranties of |
||||
title, merchantability, fitness for a particular purpose, non |
||||
infringement, or the absence of latent or other defects, accuracy, or |
||||
the present or absence of errors, whether or not discoverable, all to |
||||
the greatest extent permissible under applicable law. |
||||
c. Affirmer disclaims responsibility for clearing rights of other persons |
||||
that may apply to the Work or any use thereof, including without |
||||
limitation any person's Copyright and Related Rights in the Work. |
||||
Further, Affirmer disclaims responsibility for obtaining any necessary |
||||
consents, permissions or other rights required for any use of the |
||||
Work. |
||||
d. Affirmer understands and acknowledges that Creative Commons is not a |
||||
party to this document and has no duty or obligation with respect to |
||||
this CC0 or use of the Work. |
