This is a public domain dedication based on the Worldwide Public Domain Dedication by Jason Self. As I have the increasing demand to formalize my public domain stuff, I am hereby modifying version the WPDD for personal use. I don't think it's a good idea for others to use this, because it hasn't been checked by professional lawyers yet. But anyways, here it is, out of necessity.
Runxi Yu's Public Domain Dedication Version 1. Copying and distribution of this file, with or without modification, are permitted in any medium without royalty, provided this notice is preserved. To avoid potential confusion, if you make modifications please don't call your version Runxi Yu's Public Domain Dedicator, the Worldwide Public Domain Dedication or anything else that might be confusingly similar. This file is offered as-is, without any warranty. Statement of Purpose The laws of most jurisdictions throughout the world automatically confer exclusive Copyright and Related Rights (defined below) upon the copyright holder(s) (each and all, a "holder") of an original work of authorship and/or a database (each, a "Work"). Certain holders 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 holders 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 or organization associating this Runxi Yu's Public Domain Dedication with a Work (the "Affirmer"), to the extent that they are a holder of Copyright and Related Rights in the Work, voluntarily elects to apply this Runxi Yu's Public Domain Dedication to the Work and publicly distribute the Work under its terms, with knowledge of their Copyright and Related Rights in the Work and the meaning and intended legal effect of this Runxi Yu's Public Domain Dedication on those rights. 1. Copyright and Related Rights. A Work made available under this Runxi Yu's Public Domain Dedication 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 the extraction, dissemination, use and reuse of data in a Work; v. 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); vi. 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 this Runxi Yu's Public Domain Dedication 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 they will not (i) exercise any of their 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. Waiver of Patent Rights. Notwithstanding the provisions of section 2, Affirmer acknowledges that the design codes, utility, technical figures, charts, methods, processes, and all information related to the patent/invention arising out of the Work, the sources, source codes, objects, object codes and all system documentation relating thereto shall not be confidential and shall be non-proprietary for the public worldwide. 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 patent rights and associated claims and causes of action, whether now known or unknown (including existing as well as future claims and causes of action) throughout the world, whether arising under federal law, state law, common law, foreign law, or otherwise, for any patent/invention included by Affirmer in the Work that are licensable by the Affirmer, both currently owned or controlled and acquired or controlled in the future (the "Waiver of Patent Rights"). The Waiver of Patent Rights 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. 5. Patent Grant Fallback. Should any part of the Waiver of Patent Rights for any reason be judged legally invalid or ineffective under applicable law, then the Waiver of Patent Rights shall be preserved to the maximum extent permitted taking into account Affirmer's express Statement of Purpose. In addition, to the extent the Waiver of Patent Rights is so judged Affirmer hereby grants to each affected person a royalty-free, non transferable, non sublicensable, non exclusive, irrevocable and unconditional license to Affirmer's patent rights, where such license applies only to those patents/inventions included by Affirmer in the Work that are licensable by Affirmer, both currently owned or controlled and acquired or controlled in the future, that are necessarily infringed by making, having made, using, selling, offering for sale, importing or transferring the Work, or otherwise practicing any method or procedure in any patent/invention included by Affirmer in the Work, in whole or in part, alone or in combination with or included in any other 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 "Patent License"). The Patent License shall be deemed effective as of the date this Runxi Yu's Public Domain Dedication was applied by Affirmer to the Work. Should any part of the Patent 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 Patent License, and in such case Affirmer hereby affirms that they will not (i) exercise any of their patent 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. 6. Versions. New versions of the Runxi Yu's Public Domain Dedication may be released via https://www.andrewyu.org/note/pubdom.html in order to address issues or concerns that come up. Such new versions shall remain similar in spirit to provide, as closely as possible, a total waiver of all rights. Any person or organization receiving a Work covered by this version of the Runxi Yu's Public Domain Dedication may elect to apply any later version of the Runxi Yu's Public Domain Dedication to that Work. 7.
