ed "work".A "work" is any creative material made by a person. A painting, a graphic, a book, a song/lyrics to a song, or a photograph of almost anything are all examples of "works". A CC license is used when an author wants to give other people the right to share, use, and build upon a work that the author has created. CC provides an author flexibility (for example, they might choose to allow only non-commercial uses of a given work) and protects the people who use or redistribute an author's work from concerns of copyright infringement as long as they abide by the conditions that are specified in the license by which the author distributes the work. There are several types of Creative Commons licenses. Each license differs by several combinations that condition the terms of distribution. They were initially released on December 16, 2002, by

status. Version 1.0 of the licenses was officially released on 16 December 2002.


Origins

The CCL allows inventors to keep the rights to their innovations while also allowing for some external use of the invention. The CCL emerged as a reaction to the decision in '' Eldred v. Ashcroft'', in which the

that extended the copyright term of works to be the last living author's lifespan plus an additional 70 years.


License porting

The original non-localized Creative Commons licenses were written with the U.S. legal system in mind; therefore, the wording may be incompatible with local legislation in other jurisdictions, rendering the licenses unenforceable there. To address this issue, Creative Commons asked its affiliates to translate the various licenses to reflect local laws in a process called "
porting In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program (meant for such execution) was originally desi ...
". As of July 2011, Creative Commons licenses have been ported to over 50 jurisdictions worldwide.


Chinese use of the Creative Commons license

Working with Creative Commons, the Chinese government adapted the Creative Commons License to the Chinese context, replacing the individual monetary compensation of U.S. copyright law with incentives to Chinese innovators to innovate as a social contribution. In China, the resources of society are thought to enable an individual's innovations; the continued betterment of society serves as its own reward. Chinese law heavily prioritizes the eventual contributions that an invention will have towards society's growth, resulting in initial laws placing limits on the length of patents and very stringent conditions regarding the use and qualifications of inventions.

Applicable works

Work licensed under a Creative Commons license is governed by applicable copyright law. This allows Creative Commons licenses to be applied to all work falling under copyright, including: books, plays, movies, music, articles, photographs, blogs, and websites.

or fair dealing or exert restrictions which violate copyright exceptions. Furthermore, Creative Commons licenses are non-exclusive and non-revocable. Any work or copies of the work obtained under a Creative Commons license may continue to be used under that license. When works are protected by more than one Creative Commons license, the user may choose any of them.


Preconditions

The author, or the licensor in case the author did a contractual transfer of rights, need to have the exclusive rights on the work. If the work has already been published under a public license, it can be uploaded by any third party, once more on another platform, by using a compatible license, and making reference and attribution to the original license (e.g. by referring the URL of the original license).


Consequences

The license is non-exclusive, royalty-free, and unrestricted in terms of territory and duration, so it is irrevocable, unless a new license is granted by the author after the work has been significantly modified. Any use of the work that is not covered by other copyright rules triggers the public license. Upon activation of the license, the licensee must adhere to all conditions of the license, otherwise the license agreement is illegitimate, and the licensee would commit a copyright infringement. The author, or the licensor as a proxy, has the legal rights to act upon any copyright infringement. The licensee has a limited period to correct any non-compliance.


Types of licenses


Four rights

The CC licenses all grant "baseline rights", such as the right to distribute the copyrighted work worldwide for non-commercial purposes and without modification. In addition, different versions of license prescribe different rights, as shown in this table: The last two clauses are not free content licenses, according to definitions such as DFSG or the

In 2010, Creative Commons announced its Public Domain Mark, a tool for labeling works already in the public domain.

Retired licenses

Due to either disuse or criticism, a number of previously offered Creative Commons licenses have since been retired, and are no longer recommended for new works. The retired licenses include all licenses lacking the Attribution element other than CC0, as well as the following four licenses: * Developing Nations License: a license which only applies to

Version 4.0

The latest version 4.0 of the Creative Commons licenses, released on November 25, 2013, are generic licenses that are applicable to most jurisdictions and do not usually require ports. No new ports have been implemented in version 4.0 of the license. Version 4.0 discourages using ported versions and instead acts as a single global license.


Rights and obligations


Attribution

Since 2004, all current licenses other than the CC0 variant require attribution of the original author, as signified by the BY component (as in the preposition "by"). The attribution must be given to "the best of ne'sability using the information available". Creative Commons suggests the mnemonic "TASL": ''title'' -- ''author -- source'' eb link-- C''licence''.
Generally this implies the following: * Include any copyright notices (if applicable). If the work itself contains any copyright notices placed there by the copyright holder, those notices must be left intact, or reproduced in a way that is reasonable to the medium in which the work is being re-published. * Cite the author's name, screen name, or user ID, etc. If the work is being published on the Internet, it is nice to link that name to the person's profile page, if such a page exists. * Cite the work's title or name (if applicable), if such a thing exists. If the work is being published on the Internet, it is nice to link the name or title directly to the original work. * Cite the specific CC license the work is under. If the work is being published on the Internet, it is nice if the license citation links to the license on the CC website. * Mention if the work is a derivative work or adaptation. In addition to the above, one needs to identify that their work is a derivative work, e.g., "This is a Finnish translation of riginal workby uthor" or "Screenplay based on riginal workby uthor"


Non-commercial licenses

Adaptability

Rights in an adaptation can be expressed by a CC license that is compatible with the status or licensing of the original work or works on which the adaptation is based.


Legal aspects

The legal implications of large numbers of works having Creative Commons licensing are difficult to predict, and there is speculation that media creators often lack insight to be able to choose the license which best meets their intent in applying it. Some works licensed using Creative Commons licenses have been involved in several court cases. Creative Commons itself was not a party to any of these cases; they only involved licensors or licensees of Creative Commons licenses. When the cases went as far as decisions by judges (that is, they were not dismissed for lack of jurisdiction or were not settled privately out of court), they have all validated the legal robustness of Creative Commons public licenses.


Dutch tabloid

In early 2006, podcaster

sued a Dutch tabloid who published photos from Curry's Flickr page without Curry's permission. The photos were licensed under the Creative Commons Non-Commercial license. While the verdict was in favor of Curry, the tabloid avoided having to pay restitution to him as long as they did not repeat the offense. Professor Bernt Hugenholtz, main creator of the Dutch CC license and director of the Institute for Information Law of the University of Amsterdam, commented, "The Dutch Court's decision is especially noteworthy because it confirms that the conditions of a Creative Commons license automatically apply to the content licensed under it, and binds users of such content even without expressly agreeing to, or having knowledge of, the conditions of the license."

using a Creative Commons-BY (Attribution) license. Users licensing their images this way freed their work for use by any other entity, as long as the original creator was attributed credit, without any other compensation required. Virgin upheld this single restriction by printing a URL leading to the photographer's Flickr page on each of their ads. However, one picture, depicting 15-year-old Alison Chang at a fund-raising carwash for her church, caused some controversy when she sued Virgin Mobile. The photo was taken by Alison's church youth counselor, Justin Ho-Wee Wong, who uploaded the image to Flickr under the Creative Commons license. In 2008, the case (concerning personality rights rather than copyright as such) was thrown out of a Texas court for lack of jurisdiction.


SGAE vs Fernández

The Lower Court rejected the collecting society's claims because the owner of the bar proved that the music he was using was not managed by the society. In February 2006, the Cultural Association Ladinamo (based in Madrid, and represented by Javier de la Cueva) was granted the use of copyleft music in their public activities. The sentence said:

GateHouse sued That's Great News for copyright infringement and breach of contract. GateHouse claimed that TGN violated the non-commercial and no-derivative works restrictions on GateHouse Creative Commons licensed work when TGN published the material on its website. The case was settled on August 17, 2010, though the settlement was not made public.


''Drauglis v. Kappa Map Group, LLC''

The plaintiff was photographer Art Drauglis, who uploaded several pictures to the photo-sharing website Flickr using Creative Commons Attribution-ShareAlike 2.0 Generic License (CC BY-SA), including one entitled "Swain's Lock, Montgomery Co., MD.". The defendant was Kappa Map Group, a map-making company, which downloaded the image and used it in a compilation entitled "Montgomery Co. Maryland Street Atlas". Though there was nothing on the cover that indicated the origin of the picture, the text "''Photo: Swain's Lock, Montgomery Co., MD Photographer: Carly Lesser & Art Drauglis, Creative Commoms'' '', CC-BY-SA-2.0''" appeared at the bottom of the back cover. The validity of the CC BY-SA 2.0 as a license was not in dispute. The CC BY-SA 2.0 requires that the licensee to use nothing less restrictive than the CC BY-SA 2.0 terms. The atlas was sold commercially and not for free reuse by others. The dispute was whether Drauglis' license terms that would apply to "derivative works" applied to the entire atlas. Drauglis sued the defendants in June 2014 for copyright infringement and license breach, seeking declaratory and injunctive relief, damages, fees, and costs. Drauglis asserted, among other things, that Kappa Map Group "exceeded the scope of the License because defendant did not publish the Atlas under a license with the same or similar terms as those under which the Photograph was originally licensed." The judge dismissed the case on that count, ruling that the atlas was not a derivative work of the photograph in the sense of the license, but rather a collective work. Since the atlas was not a derivative work of the photograph, Kappa Map Group did not need to license the entire atlas under the CC BY-SA 2.0 license. The judge also determined that the work had been properly attributed. In particular, the judge determined that it was sufficient to credit the author of the photo as prominently as authors of similar authorship (such as the authors of individual maps contained in the book) and that the name "CC-BY-SA-2.0" is sufficiently precise to locate the correct license on the internet and can be considered a valid URI of the license.

reported that a German blogger Christoph Langner used two licensed photographs from Berlin photographer Dennis Skley on his private blog Linuxundich. Langner duly mentioned the author and the license and added a link to the original. Langner was later contacted by the ''Verband zum Schutz geistigen Eigentums im Internet'' (VGSE) (Association for the Protection of Intellectual Property in the Internet) with a demand for €2300 for failing to provide the full name of the work, the full name of the author, the license text, and a source link, as is required by the fine print in the license. Of this sum, €40 goes to the photographer, and the remainder is retained by VGSE. See also: The Higher Regional Court of Köln dismissed the claim in May 2019.
