Are clothing designs described in literature protected by copyright? Here's an example (source is Artemis Fowl: The Atlantis Complex) Yes, [the t-shirt] is so cool. There's a picture of a boy who for some reason has no neck and only three fingers on each hand, and behind him in this sort of graffiti style is the words RANDOMOSIY. If someone wanted to print t-shirts of this design and sell them, would they need permission to do so?
It's questionable, because if you design your own visual interpretation of the T-Shirt then it isn't necessarily the one from the book and thus your art has it's own copyright. However, if the current Copyright Holder and Possible Trademark owner is selling the shirt it could be an issue because yours is not official but being sold as one. If you're making it for non-sale and just cosplay, than you have a better arguement.
Can a system include such information? it is surely technically possible. Would it be a violation of copyright? That depends. First of all, any such information can be included if the copyright holder has granted permission, probably in the form of a license. But in that case this question would probably not have been asked. I therefore assume that no permission has been granted. (It doesn't matter if a request was made and the answer was &quot;no&quot;, a request was made but ignored, or no request was ever made. No permission is still no permission.) The names of fictional locations are nor protected by copyright. Including, say, &quot;Rivendell&quot; or &quot;Hobbiton&quot; in the selection list for a timezone setting would not infringe the copyrights held by the Tolkien estate. But a map is a different thing. If the OS includes and can display a map of a fictional region, one that is copied from or based on a map published with the fiction, or by some third party, then that would almost surely be copyright infringement, and the copyright holder could choose to sue for infringement. S/he might choose not to sue, but that is a risky gamble to take. If this is in the US, statutory damages could be awarded, and could intheory go as high as $150,000, although they are not likely to be as high as that, that is just the maximum legal limit (per work infringed, not per copy). The standard is whatever amount the court thinks &quot;just&quot;, up to the maximum. (If proof of willful infringement is not made, the upper limit is $30,000, still a sizable sum.) If the OS designer created the map independently, using names from the fiction, but not otherwise basing it on the fiction, and in particular not imitating any map created by anyone else, then it may well not be infringement, but it would still be wise to consult a copyright lawyer. The question would be more helpful if it made clear just what would be hypothetically included in the OS, and to what extent it would be based on someone else's work. There is also the question of why someone would want to include fictional places, but that really doesn't change the legal issue.
Your example powers are tropes and their basis in public domain The Queen of Pain's scream is modeled after the Banshee, which had a scream that would kill... and there are LOTS of variants of Banshee. In fact, &quot;Our Banshees Are Louder&quot; is a trope. Hiding in a shadow or walking through it is for example a typical feature of Ninja stories since the Edo Period, and a common Trope as &quot;Shadow walker&quot;. That makes those two powers older than You can not have a copyright on concepts, facts, or ideas. Facts are not copyrightable, which was decided LONG ago over Feist v Rural. Neither can you copyright concepts or ideas. You won't get a claim on the concept of a damaging scream or turning into shadow. See also Copyright.gov (emphasis mine): How do I protect my idea? Copyright does not protect ideas, concepts, systems, or methods of doing something. You may express your ideas in writing or drawings and claim copyright in your description, but be aware that copyright will not protect the idea itself as revealed in your written or artistic work.
Per a decision of the US Copyright Office last month, AI generated images are not subject to copyright. That means you can use the generated images for any purpose you want1, but so can anyone else. However, the specific usage of a given image might be protected - so if you put a caption on the image and arrange it in the form of a comic (as the artist in that example did), that specific text and arrangement can be protected, but the underlying image can't be. Laws may differ elsewhere in the world, but that's the current stance in the US. 1 Subject to any appropriate laws, including any copyright laws which the new image itself may violate. Just because the image isn't protected itself doesn't mean that it can't infringe on someone else's copyrights. See the other answer for more details.
You don't just want to ask, you are required to obtain a license (or in other terms: the OK of the author*). Your game is based on a book. That makes your game a derivate work. Under berne convention, any signer state has to make sure that the author* has the right to authorize any derivate. That includes translations, films, or games. Without a license, you violate copyright law. It doesn't matter if your game is free. To stay safe, you need to obtain a license. Quite some authors would be happy to cut a deal, license or guidelines for fan-projects. As an example, the late Sir Terry Pratchett OBE has specific guidelines on what is ok and what not. Ask your author* about these questions and consult a Lawyer! Only then make your fan project! * This means the author, their estate or whoever they assigned their rights in the work to. Some examples: For that teenage wizard in a private castle charter school that'd be a certain J.K. Rowling. For those hairy-halflings running all over the continent hunted by orcs that'd be the J.R.R. Tolkien-Estate. And for those space wizards using blades from solid light that'd be The Walt Disney Company or one of their subsidiaries.
In the U.S. the text and drawings of a patent application/patent may be copyrighted by the author. If such protections are being claimed, the patent application must contain this authorization from 37 CFR 1.71 (d) and (e)- e) The authorization shall read as follows: A portion of the disclosure of this patent document contains material which is subject to (copyright or mask work) protection. The (copyright or mask work) owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all (copyright or mask work) rights whatsoever.
You would be in poorly-tested waters under US law. The invented name &quot;Cthulhu&quot; as appearing in a novel is not protected by copyright. A collection of invented names and other words assembled into a dictionary (e.g. of Klingon) might be found to constitute a copyright-protected creative work. In Paramount Pictures v. Axanar Productions (complaint), plaintiffs partially base their claim on infringement of language; defendants sought to dismiss the suit on various grounds (&quot;questions of law&quot; rather than questions of fact), but the court denied defendant's motion for summary judgment. Subsequently, defendants settled the case. Constructed languages are highly creative expressive works whose elements are deliberately selected for an artistic purpose, and they are not naturally-occurring facts. The copyright office has no position on copyright protection of a constructed language, and any such position would have to come from so-far non-existent (definitive) case law. The dismissal in Paramount v. Axanar doesn't clearly indicate that a constructed language is protected. The primary legal question would be whether the database that you copy into your system is protected. There is a colorable legal argument that a collection of language-like objects. The statutory language in 17 USC 102 does not specifically preclude protection of a wholely-creative database, and the copyright office does not say whether a conlang can be protected because the courts have not ruled one way or the other. The situation in Feist is very different from the case of a work which invents a language from nothing.
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.
