What gives me the right to use user-generated content for ... anything? I'm building a website where users contribute original content to a collaborative story writing process. I assume since they are submitting it to such a site, they are implicitly giving me the right to display said work on the site. I understand that I cannot claim copyright ownership of said work, but for example, when I make a post on Reddit, Reddit doesn't own the content I wrote, but yet they are still permitted to display it to all other users who visit their site. Since I own the copyright to my own work, do I have the right to send Reddit a take-down notice for my own work (assuming I didn't already have the ability to delete my own post)? Could users do this to me on my site? I would eventually like to be able to use this user-generated content on my site for other purposes, all expressly related to or in the context of my site (e.g. publishing a compilation of user-generated work from multiple users, either for free or at-cost). Is this in any way possible without some process of getting legal documentation from every user of my site? In short, is there any way to enforce that original content posted to my site shall be covered by commercial-use-allowable Creative Commons or other such licenses, effectively making them public domain or something like that? I understand that I'm throwing some of these terms around a bit without really using them correctly. I don't know anything about legal stuff, this is a hobby project and I basically just don't want to get myself into trouble. It's already on my radar to provide an avenue for owners of copyrighted material to send me take-down notices if they find that a user of my site has posted their content without permission, but when a user posts their own original content to my site, I want to know what I am allowed to do with it.
The answer depends in part what venue you're talking about, e.g. Reddit, Facebook etc. The details are revealed somewhere in the Terms of Service for that venue. The general pattern is that you are allowed to use that venue, provides you grant permission for the service to do what they do with your content. You cannot legally send them a take-down notice for your stuff, because a take-down notice requires you to say that the stuff was posted without your permission (and that is false – and you can be punished for making that statement). There could be a venue where they do not hold you to an irrevocable license, in which case you could revoke that permission (but not Reddit: you granted them a "royalty-free, perpetual, irrevocable, non-exclusive, unrestricted, worldwide license to reproduce, prepare derivative works, distribute copies, perform, or publicly display your user content in any medium and for any purpose, including commercial purposes, and to authorize others to do so"). I've seen a site that actually asserts ownership of user-contributed content (I don't know if their TOS ended up being litigated) – if is not at all hard to write a TOS that includes transfer of copyright, rather than granting of a license. The only hard parts are (1) figuring out what you want in terms of permission to use and (2) whether your answer to (1) means nobody will use your service. SE and Reddit TOS probably are as close as you need to get for what you describe.
No It says right on the page you linked: These downloads are not public domain, as they are parts of content that has already been licensed and distributed. Although using these downloads may be permissible as long as the project itself falls under the rule of "Fair Use," it is ill-advised to use these downloads for any project intended for profitable gain or commercial advertisement, unless otherwise stated by Kyutwo.com.
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.
You can do whatever you like with posts made after you change the rules - you have to leave the previous stuff alone. The contributors' have accepted the terms of the licence: They own the copyright or have permission from the copyright holder to post it (the promise) They agree that it can be edited altered or removed CC-BY-SA allows people to copy the stuff off the website and republish it - this is way outside what the contributors agreed to. These people have given permission for their work to be altered but not copied.
All your work is yours. They've made it very clear it wasn't a work for hire, so it's yours. They can't copyright any of their ideas. You can't copyright an idea. Only specific creative elements authored by them and present in your work could be covered by copyright. You didn't use their block diagrams. I don't see how references to other sites to look at would constitute a creative element they authored. That said, you probably want to talk to a lawyer and get a written legal opinion that you can rely on.
It doesn't make a difference if the product is free or commercial use, if it's initiated by a company or an individual. What you are considering would be a &quot;derivative work&quot; and without explicit permission from the copyright holder, it is considered a violation.
Yes, you can grant any license you want to your larger work. With respect to Creative Commons, they provide guidance: May I apply a CC license to my work if it incorporates material used under fair use or another exception or limitation to copyright? Yes, but it is important to prominently mark any third party material you incorporate into your work so reusers do not think the CC license applies to that material. The CC license only applies to the rights you have in the work. For example, if your CC-licensed slide deck includes a Flickr image you are using pursuant to fair use, make sure to identify that image as not being subject to the CC license. For more information about incorporating work owned by others, see our page about marking third party content. Read more considerations for licensors here. With respect to MIT License for software, I don't think that many of the reasons for fair use apply to using someone else's source code in your project. If you're creating criticism, commentary, news, or educational material, you probably have more than just code. You should choose a more appropriate license for the complete work (like a Creative Commons License). Taking someone's software source code and trying to use it under fair use may also lead to issues when you consider other factors, such as the purpose of the use, the amount included in the larger work, and the effect of value on the copyrighted work. I'm not finding a lot of cases regarding fair use in software. Galoob v. Nintendo found that you can modify copyrighted software for personal use (not relevant to this discussion). Sega v. Accolade found that copying software for reverse engineering was fair use under certain conditions (again, not relevant here). If you are attempting to use anything under fair use, regardless of the license that you apply to your larger work, you do need to ensure that you do not give the impression that each individual piece of that work is also under that licence once extracted. That's why you need to clearly mark which portions are used pursuant to fair use. If those portions are extracted from the larger work, then the original restrictions to use apply. However, someone can use the larger work under the license you grant. I just wanted to add this brief section to be extremely clear. When you are producing a work, you can choose a license for that work. If you are incorporating someone else's work into your own work, there are two possibilities: You obtain the other person's work under a license. You must abide by this license and all of its requirements. Some licenses are viral in nature, which restrict the licenses that you can apply to the larger work. You use the other person's work under fair use. In this case, you need to properly attribute the work and identify that it is not available under the same license as the larger work. Someone that extracts that smaller portion must abide by the copyright of that work. If it's available under a particular license, they can choose to use that license or under fair use if they are able to. Someone using your complete combined work uses your license.
Although the exact answer should depend on the country you are, in general private copies of copyrighted works are allowed. General rules are: You need to have got the work in a legitimate way. That is, that you have purchased a copy of the work with permission from copyright owners or you have got the work from an act of public distribution authorised by copyright owners - if you got it from a website that is not making a copyright infringement itself, you are in the second case. That you don't make a collective or commercial use of the work. (I took these rules from Spanish Intellectual Property law (article 31), but most countries have similar rules, specially in the European Union. Anyway, the exact limits of private copying exception may differ). Since private copying might have an economic effect, some countries collect private copying levies to compensate copyright owners - probably you have already paid for those when purchasing the printer. Therefore, you can print a book downloaded from a website (unless the site is hosting the work without authorization of the copyright owners, as pirate sites do) for your own use. You can't sell the copies or made a collective use of them. Although reach of collective use might be hard to assess, I would suggest that if you want all the people in your class have the book, send them the link so that any one could print their own copy. Update about the USA As the OP has now specified now their country I update the answer with a comment, although an additional answer by anybody more knowledgeable on US law would be great. I'm quite sure that for practical purposes the result is that you can print such a book anywhere in the world. However, I don't know which laws regulates that in the US. Google doesn't return meaningful results for "private copy usa", so I suppose it is know there by another name. Furthermore, statutes in common law countries tend to be less explicit and there might be no case law applicable. For example, I nobody printing a copy of a pdf for himself to read at home has ever been challenged in court in the USA, there might be no explicit rule about the subject.
