Can a writer write a novel about a fictional Dota player? Can a writer/author write a novel about a fictional Dota (or any other video game) player, mentioning the game's name and possibly names of the fictional characters of the game? Would this be trademark infringement (requiring the game's name to be changed)?
Under US law: It depends, but it is likely legal. Trademark is designed to prevent confusion in consumers, to avoid someone's good work and reputation from being taken advantage of by another, and/or damaged by another's poor work/service. The game's name and character names are (generally) not trademarked, nor are they copyrightable. Even if they were, there is nominative fair use to consider as a defense. There are still some legal issues that might occur (e.g. this does not apply to the novel's name; using the game's logo on cover art might constitute trademark violation if it was so positioned as to be associating a relationship with the game publisher, descriptions of the game's content, especially story content, is a bit hazy), but not with using the game name or character names.
The film you want to base your game on is probably covered by copyright and likely trademarks. For purposes of the question I'll assume it's not in the public domain (if the film was made before 1926 for example). If you used the film to create your game, it would be a derivative work. Derivative works require the consent of the copyright owner. Distributing it without their permission would leave you open to lawsuits for copyright infringement, unjust enrichment, and possibly others. Fair use/fair dealing likely doesn't apply here. This isn't criticism, parody, or a transformative use. You may be able to get away with this by flying under the radar if you don't distribute it for profit or on any large scale. Some studios are more litigious than others and some accept that leaving fan works alone is better than the bad publicity that comes with shutting them down. However, this is entirely reliant on the goodwill of the studio. The legal way to do this is to get in touch with the copyright holder and ask permission. This may be in return for something else- usually money, royalties, and/or some creative control over your work. This may not be feasible though as a large company may simply ignore such requests from random people. Note that a lack of a response in this case is not permission.
It depends on the game and what you copy. Games are an utter nightmare when it comes to IP law as so many parts of them cannot be copyrighted. Game rules for example cannot be copyrighted, nor can the concept itself. Some things can be copyrighted or trademarked. You cannot use the following: Names Written elements- while the rules themselves can't be copyrighted, rulebooks can Artwork and other visual elements Miniatures designed for the game Original characters Try to avoid these and the Hasbro lawyers should leave you alone.
In the US, the author would be able to wind an infringement lawsuit against the re-publisher. Title 17, the US copyright law codified, grants the author the exclusive right to authorize republication, and does not require that a person use their real name. The argument "It was on the internet, it's in the public domain" is utterly without legal merit. The same goes for the assertion that a person loses his rights if he is uncontactable. The author has stated the terms of the license, so there isn't even a reasonable argument that the infringement is innocent (unknowing: "I thought it was with permission). There is no requirement that you have to allow a potential user to hassle you about the license terms. The one thing that is special regarding anonymous and pseudonymous works is that under 17 USC 302, "copyright endures for a term of 95 years from the year of its first publication, or a term of 120 years from the year of its creation, whichever expires first". For a work whose author is identified, copyright "endures for a term consisting of the life of the author and 70 years after the author’s death". This assumes that the host site has not preempted author's license: Stack Exchange, for example, preempts an author's exclusive right, so you can copy stuff from here accorting to the SE terms of usage.
may require that you obtain license rights from third-party owners or licensors of content that you include in your text inputs (Emphasis mine). Based solely on the excerpt above, yes, you have the copyright on the audio files if you created the source material, as you are the creator, using Amazon Polly as/to generate a "tangible medium". One of the central rights granted by copyright is to control translation into a different medium (in this case, from text into audio), as is the right to control distribution, which is what this excerpt is talking about. "Third party" in this case means neither you nor Amazon. Basically, Amazon is informing you that using their software on someone else's copyrighted material does not grant you copyright on the audio recording.
As is typical with legal matters, &quot;it depends&quot;. It is not copyright infringement to mention the name of an artist or work of art. It may be infringement of trademark, or of the right of publicity. For example, Apple Computers has trademarked the name &quot;Apple&quot; in the domain of computers, so you cannot call your computer company &quot;Apple Computers&quot;, without their permission. You also cannot advertise in a way that implies that Taylor Swift endorsed your product, without her permission – this is the &quot;right of publicity&quot; (the name may differ, e.g. &quot;passing off&quot; depending on jurisdiction). The situation in the US is highly variable, since it depends on state law. The legal inclinations of the particular artist may be irrelevant, since they often have legal arrangements with publishers, and if you are going to get sued, it might be the publisher that sues you. Hiring an attorney to evaluate the specifics of your idea is the only reasonable approach to the matter.
A statement by a fictional character is part of the fiction, and so is normally protected by copyright. A short exclamation such as &quot;You are not prepared!&quot; might be ruled to be too short and not sufficiently original to be protected if it were used separately, but that would apply just as much to a short statement that was not a quote from a character. But something like one of Gandalf's speeches on &quot;mercy and pity&quot; to Frodo in Chapter 2 (&quot;The Shadow of the past&quot;) in book 1 of The Lord of the Rings would clearly be protected. The longer and the more distinctive such a text is, the more clearly it would be protected. Whether it is put in the mouth of a character or is part of the narration makes no significant difference. Note, in a copyright sense a statement does not &quot;belong to a particular universe&quot;, rather it belongs to a copyright owner, often the author, or in the case of a video game quite likely thy publisher. As this comment by Kevin mentions, and as I should have mentioned, reproducing a short quotation from a work of fiction, particularly if properly attributed, is quite likely to be fair use. See Is this copyright infringement? Is it fair use? What if I don&#39;t make any money off it? for more specific details. See also the threads tagged fair use If a quote is used for a different purpose than the original, in what is called a &quot;transformative&quot; manner in copyright cases, then it is more likely to be held to be fair use. The smaller of a percentage of the source item the quote is, the more likely it is that it will be considered to be a fair use. The less the use of a quote serves as a replacement for the source, or harms the market for the source, the more likely it is to be considered a fair use. See the links above for more detail.
Primary Theory I suspect there might not be a legal answer to this question. I have always suspected a sort of pseudo-intellectual elitism (or simple preference or carelessness) with passive voice sentence construction in general. I sense license writers have not (yet) escaped this general trend. I would love someone to prove this theory incorrect. But, alas, I doubt it will happen. Alternative Theory But because this is a Law Q&amp;A site, I will advance the following alternative theory. I don't believe it's correct. But I will advance it because it's the only possible explanation I can think of that might be even remotely based on legal reasoning... Maybe they are just basing their construction on the way the law itself is written? For example, if the law says, "Permission must be granted..." Then it would follow that a writer who wants to comply with the law might choose, "Permission is hereby granted..." instead of something like "The authors hereby grant permission..." or, as the OP suggested, "You may..."
