What counts as redistribution of copyrighted calculation? In quantitative finance SE, there is a question asking for help calculating an index. If someone writes a program that performs the calculations described in the handbook and shares that program publicly, would it violate the index copyright? Or does the translation from English to computer program make it ok?
Copyright never protects ideas or processes, it only protects expression: words, images, and sounds, some of which may describe ideas. But when a work is nothing more than a translation of an idea into words, with no independent originality -- when almost anyone would use more or less the same way to describe the idea, then the work will not be protected by copyright at all, as it is not considered an "original work". Computer code that implements an algorithm often falls under this rule. It is my belief that the code shown in the linked SE thread would fall under this rule, and would not be protected by copyright at all. If this is correct, then anyone may share such a program with no copyright concern.
You cannot safely rely on the US doctrine of Fair Use, except if the rights-holder sues you in US courts. In France, there are limited exceptions to the authors proprietary rights. Under Art. L-122-5, there are some relevant potential exceptions: 3ºa) analyses and short quotations justified by the critical, polemic, educational, scientific or informatory nature of the work in which they are incorporated... 4º. parody, pastiche and caricature, observing the rules of the genre. Your description of the intended use does not fit these criteria. Consulting with a copyright attorney is advised, if you don't want to obtain a license.
Why would the method by which you transfer a item that has a copyright impact the copyright? You buy a new book at a new bookstore, a used book at a used bookstore, a used book at a garage sale, someone gives you a book, you find a book on the sidewalk, you steal a book from a store, you buy and download an ebook, you give an ebook to someone on a USB stick, you download an ebook via Bittorrent. The author's copyright - as well as the design copyright, and any book company trademarks - does not change in any of those scenarios. Copyright around most of the world - read Berne Convention (Wikipedia) - says that copyright exists at the moment of creation of a work, i.e. a work that you say is "100% yours". This has nothing to do with the way the work may be transmitted or stolen or downloaded. A work in the public domain can still be copyrighted in terms of cover artwork and design, annotations, etc. Read Welcome to the Public Domain - Stanford Copyright and Fair Use Center You can say someone "owns" a book in the sense that they might have paid for it or it is personal property and one could justifiably call it theft if someone took it from them, but "owning" the physical or electronic copy in any sense doesn't mean you own the copyright. Read the copyright notice on a book or ebook; you get a license to read it, not ownership of it. Read What's the difference between Copyright and Licensing? - Open Source Stack Exchange. Sure, the TOS of a network can specify the ownership/licensing status of the files shared on such network. They will almost all explicitly say not to upload or share anything that will violate the copyright of that work. The TOS of a network could possibly say that anything that is uploaded is automatically licensed to them. A network could demand the reassignment of copyright upon upload, but that would have to be outlined in the TOS and is not simple.

You may have issues if you take their content wholesale. Even if they freely distribute them, they still retain copyright. As such, they absolutely can claim copyright. Whether they will or not is another question. Your best bet around this is Fair Use doctrine. You can take a part of their work (e.g: a single question) and do your video based on how you work out your answer, with your video mainly focusing on the 'working out' part (thus satisfying the 'educational purposes' part)
We can't really know until the ruling is made. The Supreme Court might issue a ruling that encompasses all software APIs, or may predicate its ruling on this more specific situation, e.g. that because Oracle's library is so extensive its structure can be copyrighted even if that does not necessarily mean that any individual function signature can be copyrighted. They could also decide based on something unrelated to the heart of the copyright question - skimming through the petition for a writ of certiorari, they could make a decision based on the original implied license from Sun, for example. Hopefully their decision will answer the copyright question of function declarations completely, but it isn't required to.
The copyright on the book of quotations protects the collection. That is, it protects the author's choice of which quotations to include, and of what order to list them in. It also covers any division of them into groups or categories, and any added text (intros, comments, and so on) written by the author. It does not protect the quotations themselves. As those are not the original work of the author, s/he can have no copyright in them. Any quotes that are in the public domain (through expiration of copyright, or otherwise) may be used freely. Any others are protected by copyright. However the use of a short quotation is often fair use under US law, or is subject to another exception to copyright elsewhere. But that depends very much on the details of the factual situation. So quotes with expired copyrights are safe to use. Others may well be safe if they are relatively short, and proper attribution is given.
Distribution on YouTube implicates, at least, US copyright law. Shropshire v. Canning 809 F.Supp.2d 1139 (N.D. Cal. 2011), Subafilms v. MGM 24 F.3d 1088 (9th Cir. 1994) Are you infringing? Is the original work eligible for copyright? &quot;It is undisputed that computer programs— defined in the Copyright Act as a set of statements or instructions to be used directly or indirectly in a computer in order to bring about a certain result, can be subject to copyright protection as literary works.&quot; 17 USC 102, Oracle Am., Inc. v. Google, Inc., 750 F.3d 1339 (Fed. Cir. 2014) (internal citations omitted). Are you making a copy or displaying the work publicly? (17 USC 106) You concede that you are doing this in the hypothetical, so we can skip this step. Do you have permission to do this? Some work is licensed to allow your proposed use. If you have permission, then this entire answer is moot. Are you taking what amounts to a substantial taking of the original? Presumably, you will not need to show the entire source file to present the naming conventions and techniques that other developers have used. But, what you do show will be an exact reproduction of the original. In the case of computer programs, all US districts use the abstraction-filtration-comparison test. Computer Associates International, Inc. v. Altai, Inc., 982 F.2d 693 (2d Cir. 1992). The abstraction stage of this test is irrelevant in this hypothetical because the reproduction is exact. Filtration excludes any uncopyrightable elements of the original from consideration (due to scènes à faire, merger, lack of originality). The comparison stage compares what remains after the filtration stage, to determine if the new work takes substantially from the original. Fair use defense If your use is found to be infringing based on the above analysis, the affirmative defense of fair use is available. I can't tell you whether a fair use defense would be applicable or successful in your particular case. However, you can search the US Copyright Office's Fair Use Index for many examples successful fair use defenses when a literary work was reproduced in part or whole for educational purposes. There are also other affirmative defenses available (implied license, for example), or defenses that directly attack the elements of copyright infringement. Some confusion exists regarding &quot;idea/expression merger&quot; as a defense after a prima facie case of copyright infringement has been made. This isn't completely correct. Where idea/expression merger enters the analysis differs from circuit to circuit. In the 6th circuit, merger enters in the copyrightability analysis (paragraph 1. above). But, the 2nd and 9th circuits treat merger as part of the infringement analysis (paragraph 4. above) and in the 9th circuit, merger is an affirmative defense. Ets-Hokin v. Skyy Spirits, Inc., 225 F.3d 1068 (9th Cir. 2000) The idea/expression merger doctrine is not implicated just because &quot;the idea one that is expressing is 'this is the code they used.'&quot; When you need to cite/show the original work for purposes of &quot;criticism, comment, news reporting, teaching&quot;, that is a direct implication of fair use. Using using this justification triggers the full four-factor fair use analysis. (17 USC 107). You don't get to reproduce a work just because you want to say &quot;this is the work they created.&quot;
united-states The flowchart included in the question is trying to summarize a rather large amount of legal uncertainty into one image. It must be emphasized that each decision point represents an unsettled area of law. Nobody knows which path through that flowchart the law will take, or even if different forms or implementations of AI might take different paths. The short and disappointing answer to your question is that nobody knows what is or isn't legal yet. To further elaborate on each decision point: The first point is asking whether the training process requires a license at all. There are two possible reasons to think that it does not: AI training is protected by fair use (see 17 USC 107). This is a case-by-case inquiry that would have to be decided by a judge. AI training is nothing more than the collection of statistical information relating to a work, and does not involve &quot;copying&quot; the work within the meaning of 17 USC 106 (except for a de minimis period which is similar to the caching done by a web browser, and therefore subject to a fair use defense). The second point is, I think, asking whether the model is subject to copyright protection under Feist v. Rural and related caselaw. Because the model is trained by a purely automated process, there's a case to be made that the model is not the product of human creativity, and is therefore unprotected by copyright altogether. Dicta in Feist suggest that the person or entity directing the training might be able to obtain a &quot;thin&quot; copyright in the &quot;selection or organization&quot; of training data, but no court has ever addressed this to my knowledge. This branch can also be read as asking whether the output of the model is copyrightable, when the model is run with some prompt or input. The Copyright Office seems to think the answer to that question is &quot;no, because a human didn't create it.&quot; The third decision point is, uniquely, not a legal question, but a practical question: Do you intend to distribute anything, or are you just using it for your own private entertainment? This determines whether you need to consult the rest of the flowchart or not. The final decision point is whether the &quot;output&quot; (i.e. either the model itself, or its output) is a derivative work of the training input. This would likely be decided on the basis of substantial similarity, which is a rather complicated area of law. To grossly oversimplify, the trier of fact would be shown both the training input and the allegedly infringing output, and asked to determine whether the two items have enough copyrightable elements in common that copying can reasonably be inferred.
