Is it copyright infringement to make a derivative work for personal use in the US? In this comment, user253751 writes: You cannot create derivative works without permission of the copyright holder (even if you create it and keep it to yourself) really? That seems unconstitutional or something (in countries that have that). You should be allowed to do whatever you want with your own stuff in your own home. Is the maker of the comment correct? Or is the quoted answer (by user gnasher729) correct? What is the US law on making derivative works?
The comment is incorrect; creating a derivative work without permission is still disallowed, even for private use. In US copyright law 17USC 106 defines the exclusive rights that the copyright holder has, the right &quot;to do and to authorize&quot;. The second of these is: (2) to prepare derivative works based upon the copyrighted work; Note that the right is the right to &quot;prepare&quot; a derivative work, not the right to &quot;distribute&quot; or &quot;sell&quot; the work. US copyright law defines a derivative work in 17 USC 101 which reads: A “derivative work” is a work based upon one or more preexisting works, such as a translation, musical arrangement, dramatization, fictionalization, motion picture version, sound recording, art reproduction, abridgment, condensation, or any other form in which a work may be recast, transformed, or adapted. A work consisting of editorial revisions, annotations, elaborations, or other modifications, which, as a whole, represent an original work of authorship, is a “derivative work”. The laws of other countries are similar to US law on this point. Article 2, paragraph 3 of the Berne Copyright Convention provides that: (3) Translations, adaptations, arrangements of music and other alterations of a literary or artistic work shall be protected as original works without prejudice to the copyright in the original work. However, it should be noted that if a person creates a derivative work in private, and never shows it to anyone else, the copyright owner would never learn of it, and so could never sue for infringement. But if it were shown or described to anyone, and the owner did learn, then he owner could in theory sue. Whether the owner would choose to sue over a derivative work never circulated is a different matter. The real effect of this law is that when an infringing derivative work is distributed and the owner wants to sue, the owner need not prove distribution. Proving creation of the derivative work is enough. The quoted comment asks about whether such a rule is &quot;unconstitutional or something&quot; and says that &quot;You should be allowed to do whatever you want with your own stuff in your own home.&quot; The US constitution does not grant any such broad right. There are lots of things one might do in own's own home that are illegal: building a bomb for example. Article I, Section 8, Clause 8 of the US Constitution, sometimes called the Copyright Clause or the IP clause, grants Congress the power: To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries. See the LII page &quot;Intellectual Property Clause&quot; and the page Nature and Scope of the Right Secured for Copyright where it is written that: Congress was within its powers in giving to authors the exclusive right to dramatize any of their works. Even as applied to pantomime dramatization by means of silent motion pictures, the act was sustained against the objection that it extended the copyright to ideas rather than to the words in which they were clothed. {Kalem Co. v. Harper Bros., 222 U.S. 55 (1911). For other problems arising because of technological and electronic advancement, see, e.g., Fortnightly Corp. v. United Artists Television, Inc., 392 U.S. 390 (1968); Sony Corp. v. Universal City Studios, 464 U.S. 417 (1984).} See also the Wikipedia article &quot;Copyright Clause&quot;.
Generally, no, this will not violate copyright. Your end user might violate copyright, but that is their problem not yours. Your program is a tool, just like a word processor is. If I copy a Harry Potter book into a word processor that does not make the word processor maker liable. There is a concept of "contributory infringement", which I think is what you are concerned about. I don't know about Danish law in particular, but most countries would require evidence that you had reasonable knowledge that actual copyright violation was occuring, rather than just being aware that it might happen in theory. This is normally applied to file sharing services who have to have "notice and takedown" measures, file filters and the like. This isn't your concern as you never have any access to the files created by your users. You can also be found liable if you induce anyone to commit copyright violations. Don't draw your customers attention to the custom monster feature as a workaround for those copyrighted monsters, as that could be considered to be inducement. Also don't provide any "wizards" or similar tools which make it noticeably easier to duplicate the custom monsters (e.g. if you notice that the copyrighted custom dragon stats are all on a linear scale with dragon size, don't create a "dragon creation wizard" embodying that fact.) This assumes that your program runs entirely on the end user computer. Its different if you provide any kind of cloud storage for generated characters.
Am I as the user of this site in any way liable if the music turns out to violate copyright? Yes. In a similar way to if I give you “permission” to take my neighbour’s car. Only worse. Because stealing requires intent - you have to mean to do it - while copyright violation is strict liability - if you do it, you’re guilty. If the user that uploaded the item did not have the authority to give the site permission then the site does not have permission and neither do you. If you take reasonable precautions such as performing a reverse image source and verifying that the item appears to be owned by the same person everywhere and, perhaps, reaching out to them then your violation will be an “innocent” infringement which mitigates but does not eliminate damages. The only way to be sure with copyright is to know the provenance of the copyright/licences back to the original creator.
The situation in Texas is unclear. It is worth mentioning Texas as a state where the law may require statutory authorization in order to copyright state documents. Although the statute does not explicitly state such as a requirement, it can be inferred from an attorney general opinion. At a bare minimum, the Department of Health, the State Preservation Board, the Water Development Board, the Department of Motor Vehicles, and county governments all have statutory authority to hold copyrights. In your specific case, there's an additional complication. Something is only a work of the State of Texas if one of the following is true: 1) it was created by a government employee as part of their job duties, or 2) it was a work for hire. It's quite likely that neither of the above is true for a student newspaper, rendering the question of Texas-owned copyrights irrelevant.
Basically, you cannot do it. You are required to include the MIT license in any derivative work. However, that holds only for the parts that you import from this other project. You can identify which parts of the final product are copied from the MIT-licensed program (and indicate "these parts are subject to the following MIT license"), and then you can do whatever you want with the remainder that you wrote. The downside of not licensing your material is that nobody can use it. To use it, people would need permission, which is what a license is. If you don't license it, you don't give permission, so people can't use it. You presumably want to subject your own contribution to different licensing conditions, so then you would state those conditions and clearly indicate what parts of the code you wrote.
Is it ok to copy the game concept and even with mostly similar content like "fighting", "building houses" etc ? Yes, but ... I should also mention that pretty much my whole User Interface is based on the User Interface from "Parallel Kingdoms" Is copyright violation. Ideas are not protected by IP law. The tangible representation of those ideas (art, words, layout, format etc.) is protected.
I believe the author has published it online. I agree. It is posted at his publisher's website. However, I am unsure if I'm allowed to read it. This answer assumes you are in jurisdiction whose copyright laws is based upon the Berne convention (i.e. the civilized world + USA). Assuming it was the author published it online, it is perfectly legal to read it. Technically, the author is performing his work by putting it online, and by reading it, you are just enjoying his performance. Also, if you are in a jurisdiction with an explicit exception from copyright for personal use, or where fair use allows making copies for personal use, it would also be legal to download it, or to print it on paper (but for personal use only). As for downloading and printing for non-personal use - that is not legal in Berne jurisdictions.
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.
