Are national flags in the public domain? This is a question, for simplicity's sake concerning UN member states. Are the designs of all national flags in the public domain? Are there any examples of copyrights? I'm looking to use flags in a website. I also believe the 'Threshold of Originality' may apply (but this is probably jurisdiction specific also).
Prima facie all flags would be artistic works with copyright vesting in their creators; either the designer or the designer's employer. The copyright is probably owned by the government of the relevant country either by virtue of the creator being an employee or by transfer. However, a significant number would be in the public domain because: They were created before the legal concept of copyright existed (e.g. Denmark - 1219) The term of copyright protection has expired (e.g. United Kingdom - 1801) It is government policy that government works are public domain (e.g. United States) Notwithstanding, it is extremely unlikely that you could be successfully prosecuted for copyright breach for using a national flag design as you would have a near watertight fair use/fair dealing defence for public policy reasons.
German perspective: In German law, there is the concept of Schöpfungshöhe (threshold of originality), which is required for authorship rights (Urheberrecht) to apply to a work. Basically, the idea is that a minimum of creativity is required for something to be protected. However, that bar is rather low. Thus, for example: Literary works are protected practically always. Maps are generally protected, even though you might argue they "slavishly copy nature", because the act of choosing what to show and what not is already creative. However, a faithful photographic reproduction of a painting is not eligible for Urheberrecht to apply (LG Berlin, AZ 15 O 428/15) So yes, a "slavish copy" of a work would not qualify for protection if there is no creativity involved. Note, however, that other types of protection apart from Urheberrecht might apply, such as Sui generis database right.
There is a special exception in 17 USC 105: Copyright protection under this title is not available for any work of the United States Government, but the United States Government is not precluded from receiving and holding copyrights transferred to it by assignment, bequest, or otherwise. In the definitions, A “work of the United States Government” is a work prepared by an officer or employee of the United States Government as part of that person’s official duties.
Udemy claims that all the videos and course content are copyrighted, but does that also hold for the material of the course? Yes, all the material is copyrighted. Ideas are not, material and content is. it would be really useful to me if I could take a large part of that code ... I want to know if I am allowed, by the law, to use this code for commercial purposes, or is it protected as the intellectual property? Yes, it is protected, specifically it has copyright applied and you may only use it if the license it is distributed under allows you to - in some cases this may be a permissive license, or the code may be obtainable legitimately from another source under a permissive license, in which case its usable. But in many cases, it may not be distributed under a permissive license or indeed any license, and in such cases you will not be permitted to use it. The license under which the code is released depends on the individual course, and in many cases the source code repository or download site for the code for the course. Check their for a license.
Generally speaking, it is illegal for you to do this. Copyright gives the creator of the image the exclusive right to copy it, and just making copies to send to other people is probably not going to be fair use. Making copies without a license from the copyright holder would therefore be copyright infringement. Are there likely to be any consequences for doing this? Probably not.
The general rule under united-states law is that copyright is infringed when a copyrighted work, or any part of it, is copied or distributed without permission, or a new derivative work based on the copyrighted work is created or distributed without permission. There are several exceptions to this. There is, for example, a specific right to create a backup of a computer program to which one has lawful access. The best known and widest exception to copyright in US law is &quot;fair use&quot;. What use is a fair use is a highly fact-driven question: It cannot be answered in general, except by quoting the statutory provisions. There are no exact rules for what is and is not fair use that apply in all cases. There have been several detailed discussions of fair-use on this site, including https://law.stackexchange.com/a/66608/17500 not long ago. Note that fair use is a strictly US concept, and does not apply under any other country's law. Other countries have their own exceptions to copyright, which will cover some of the same cases as fair use, but not all of them, and will get to results by different routes. If hashes were distributed separately, to confirm the authenticity of a program, they would probably not be protected by copyright for lack of originality. Under US law, and particularly the Feist Publications, Inc., v. Rural Telephone Service Co., 499 U.S. 340 (1991) case there must be a &quot;minimal degree&quot; of creativity for something to be protected by copyright. The decision said: Many compilations consist of nothing but raw data—i.e. wholly factual information not accompanied by any original expression. On what basis may one claim a copyright upon such work? Common sense tells us that 100 uncopyrightable facts do not magically change their status when gathered together in one place. ... The key to resolving the tension lies in understanding why facts are not copyrightable: The sine qua non of copyright is originality. Since a hash or other digital signature can be computed automatically from the document to be signed (indeed that is its value), it is not creative and copying a hash alone would not be an infringement. Whether this would be true of other metadata depends on the exact nature of that data, and the degree of creativity that it represents. Without specific facts no judgement can be made, and making that kind of very specific judgement might be beyond the scope of this site. A comment said: Just because a work is copyrighted, doesn't mean every part of that work is copyrighted, ... I would put it that every part of a work is copyrighted, but some copying does not amount to infringement. Extracting facts and rewording them so that none of the expression is copied is not infringement. Extracting a completely non-creative part of a work and reproducing it is not infringement. Copying a limited amount for use in a review or commentary is often fair use, and fair use is not infringement. Video Games There is nothing in US law specific to video games. There is little that is specific to computer software, although the right to make a backup copy is protected. A good deal of case law has focused on the issue of temporary copies made while running a program, which does not seem relevant to this question. Other cases have focused on the protectability of user interfaces, and of APIs, also not relevant here. whether a work is packaged as a single file or as many related files should not affect its copyright protection. (I know of no case on that specific issue.) Whether copying a part of acomputer file is infringement or not would depend on the purpose of the copying, and on the effect or potential effect on the copyright holder, and perhaps on other factors. Copying a non-creative hash, as a way of detecting whether a file is modified or not, does not seem likely to be infringement, unless the holder could show harm, but no one knows for sure how a court would rule in such a case. Copyright does not protect facts, but it does protect the way in which facts are expressed, unless there is only one or a few such ways available to express such a fact. Copyright also may protect the selection and arrangement of facts, except where the arrangement is &quot;obvious&quot;. Placing facts in alphabetical order (as in a phone book) or chronological order (as in a timeline) has been held to be obvious and not protected. International Standards The question and a comment ask about international standards for copyright. In effect there are none. The only significant international agreement on copyright is the Berne Copyright Convention. That is a treaty to which almost every nation belongs, thus rendering the Universal Copyright Convention and other international copyright agreements obsolete. But the Berne Convention leaves details to national copyright laws. The making or authorizing of copies, and the authorizing of derivative works are part of copyright in every Bern-compliant country. Berne provides for exceptions to copyright, but leaves the details to national law. Moreover, there is no intentional court in which copyright claims can be made. Anyone wishing to sue for copyright infringement must do so in the courts of some specific country, and so all the case law which defines details on what is and is not infringement is national, not international. It should be noted that a copyright holder may sue in any country where infringing actions have occurred. When an allegedly infringing work is distributed over the web, that often means that a plaintiff may sue in almost any country, although enforcement will be limited if the defendant has no presence and no assets in the chosen country. Thus the copyright laws of multiple countries may be relevant to a particular case.
For your example of items with Marvel characters on them for sale by people and companies not licensed by Marvel, Redbubble clearly states that We ask, rather we beg, that you remember this when you are posting work on Redbubble. If you make sure that all the works you upload consist of your very own, original ideas and are not infringing on the intellectual property or publicity rights of another... (from https://help.redbubble.com/hc/en-us/articles/201579195 ) and further, Redbubble has full contact information for the submission of Notice and Takedown Reports by each real trademark owner. There are many individuals who upload products which use unlicensed artwork in violation of trademarks, and Redbubble acknowledges this and gives recourse to the license holder to inform them so they can remove the items. It's not a perfect system, but Redbubble it seems makes every effort to help police their market. ( Teepublic has a very clear policy statement, too: https://www.teepublic.com/copyright-policy ) Many companies - such as Marvel - employ agents to regularly check such websites and issue takedown demands to the sites; the sites in turn remove the products, and in some instances, ban the individual from using the site again. In the case of Amazon, there can be two types of products sold that use trademarked artwork and characters: items sold by legitimate businesses that have license agreements with the trademark owners and who have the products sold by Amazon itself; and items sold on the Amazon marketplace by individuals who open Amazon Marketplace accounts themselves and don't have licenses. Amazon will be sure to check the products they sell; they will have a takedown notices system for their marketplace vendors. eBay is somewhat the same way; there is a mix of individuals and businesses on eBay, but eBay doesn't operate an umbrella sell/ship by eBay, like Amazon. It's kind of a whack-a-mole situation on the Interwebs. How much time/money does a company spend to chase down trademark infringement? Is it worth going to court for persistent violators? (These are, for the most part, civil cases, not criminal). Violators can always open a new account on sites such as Redbubble and eBay under a different name. And it starts all over again.
Copyright in the US is usually a civil matter. Meaning that the copyright owner can sue (typically for money damages or injunctive relief) an infringer. The criminal laws that we have are aimed at the reproducer and/or distributor. In other words, chances are that you won't get in any criminal trouble for accessing academic articles of dubious origin. But never say never. RIP Aaron Schwartz.
