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.

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").
