Development and Public Comment Process
Creative Commons published three beta versions of CC0 for public comment during 2008. You can track CC0's development, including an overview of the feedback we received and main revisions to the legal code, through our blog postings here: Beta Draft 1 Beta Draft 2 Beta Draft 3. This page captures some of the main issues discussed during the public comment process and how those were resolved in version 1.0 of CC0.
Scope of Rights Surrendered
Several commentators sought clarification on the scope of the rights surrendered: does it just surrender copyright-specific rights, or is it broader and include rights such as patents, trademarks, unfair competition, privacy rights, publicity rights, commercial rights, and/or database rights.
We started to clarify these issues in Beta 2, although patent rights were only addressed in the context of facts and ideas and trademark rights were not addressed at all. In its final adoptable form, CC0 now expressly states that neither trademark nor patent rights held by the affirmer are affected by CC0.
It was also suggested during the public comment period that we make clear that the surrender of rights does not affect third party rights related to the content, such as publicity and privacy rights. While this is always the case (none of our legal tools purport to affect third party rights), we decided to include such a statement in the text of CC0 itself, as well as on the deed.
Restrictions and Limitations on Waiving Moral Rights and Related Challenges
Several CCi project leads and community members correctly pointed out the difficulties associated with waiving moral rights, particularly in European jurisdictions. A sampling of those comments can be found here:
- German Moral rights are unalienable 
- Under Australian law, you can consent to specific instances of infringement of your moral rights, but you cannot waive them. s195AW(1) of the Copyright Act 1968 states that it is not an infringement of moral rights if the infringement is within the scope of written consent given by the author. Comment from Elliott Bledsoe
- Norway - moral rights issue comment from Gisle(law cite needed)
- UK may require a signature for waiving moral right 87 (2)" Any of those rights may be waived by instrument in writing signed by the person giving up the right." Suggesting that 87(4) may provide some wiggle room but unsure how well it would work with regards to moral rights. 
- Comment suggesting that moral rights and the conversation from CC v3.01 is relevant 
- A suggestion that the only possible solution under monistic systems with strong moral rights would probably be an assertion to never claim and enforce any unwaivable right in the work, although further suggesting that courts won't be readily willing to uphold such an auxilliary construction designed to circumvene non-dispositive law. cc-license list John Hendrik Weitzmann
Following extensive consultation with our CCi jurisdiction leads, we concluded on a multi-tier approach to this and other similar issues. First, CC0 includes a Statement of Purpose in the legal code that serves in part to impress upon those using CC0 the full scope of the rights they are surrendering and the possible uses to which their works could be put, including commercial uses. Knowledge of the rights being surrendered is one important element in effecting a waiver of moral rights. Second, CC0 incorporates a fall-back public license in the event the waiver is not enforceable for any reason, since in at least some jurisdictions moral rights can be licensed even if they cannot be waived. Finally, even were the fall-back license to fail, then under CC0 the affirmer expressly agrees not to exercise his or her rights or assert claims against others contrary to the express Statement of Purpose.
A Community Effort
Building CC0 over the course of a year required the efforts and dedication of many. Our CCi leads and the broader CC community provided invaluable advice on how to craft a robust, public domain tool intended for universal use. Our pro bono legal counsel at Wilson Sonsini Goodrich & Rosati and Latham & Watkins also deserve special mention. Their legal review and analysis provided the heightened level of rigor that users of our licenses and legal tools have come to expect from Creative Commons.
Other Public Domain Dedication Resources and References
CC is not the first to create a public domain waiver or license. Below is a list of some of those tools as well as the projects that use them. If you are involved with these projects and want to discuss migrating to CC0, contact Creative Commons at email@example.com.
Community:LibriVox (audio recordings of PD books)
Name of tool used: CC public domain dedication with additional warning
Text: LibriVox recordings are in the public domain, which means people can do anything they like with them. Mostly this just means people can listen to them for free. But it also means they can: sell them (for instance on ebay), broadcast them, put them in commercials, play them at political rallies, chop them up, remix them, make music recordings of them. The recordings are free, and there is no need to credit LibriVox, although of course we much prefer if you do credit us (with a link to our site).
Here are some other examples of what people might do (and would have the right to do) with our recordings (and, if your record for us, your recordings):
- make CDs of Romance of Rubber sold as a fundraiser for a charity you don’t like;
- put Origin of the Species as background atmosphere for a pornographic film;
- sample Fables for the Frivolous in a violent rap song;
- use the summary of Frankenstein to promote a major motion picture;
Although these examples are far-fetched, they are all acceptable uses of public domain materials. So be aware of what you are doing when you free your recordings and text into the public domain. You really have to let go!
CC-PD for all art work.
Name of tool: CC-PD dedication
