Can a wiki for a video game be created without authorization from the game creator? Consider someone wants to create a wiki (user-editable community site) for Heroes of the Storm. The creator of a wiki site is not necessarily the author of any substantive content on the site, but might choose the logos, styles, initial organization, etc. Will the creator of the wiki site need to get authorization from Blizzard (the game creator) for doing this? Or is creating a wiki site protected by fair use (or a similar exception in law)?
Yes, such a site can be created without infringing copyright Facts about the game are facts.They are not protected by copyright. Criticism of, and comment about the game, is an activity protected by the US First Amendment. Making such comments is very likely to be fair use under US copyright law. In general the author of a work, such as a book or a game, or the maker of a product, has no right to grant or withhold permission to discuss or comment on the work. This is true not only under US law, but also in the law of most countries (perhaps of all countries). The name of the game might well be protected as a trademark. But that does not allow the trademark owner to prevent discussion of the game, clearly identified by the name of of the game. As long as nothing is being sold or rented, or advertised for sale or rental under that name, and there is no attempt to claim that the site is sponsored or approved by the trademark owner, and there is no likelihood of confusion, there is no trademark infringement. This is true under US law, and under the trademark laws of most other countries. A wiki is a specific technology. It can be used for community discussion, or for a company's internal documentation, or for any of many other purposes. Wikipedia has popularized this technology. Not all community discussion sites are wikis, however, nor are all wikis for community discussion. Just as not all novels are books printed on paper, and not all books are novels. In any case, setting up a wiki about a topic such as a game, a movie, or a novel does not require permission from the owner or creator of the game or of any trademarks associated with the game or work. The same would be true for a discussion forum about such a game or work that is not a wiki. If a wiki uses excessive quotes from game dialog, or uses the game's logo without permission, or reproduces other game assets, such as character art, maps, and the like without permission, that might be copyright infringement.
I believe you have just misunderstood what you paid for. Blizzard's End User License Agreement says: Your use of the Platform is licensed, not sold, to you, and you hereby acknowledge that no title or ownership with respect to the Platform or the Games is being transferred or assigned and this Agreement should not be construed as a sale of any rights. It also says: Blizzard may change, modify, suspend, or discontinue any aspect of the Platform or Accounts at any time, including removing items, or revising the effectiveness of items in an effort to balance a Game. Blizzard may also impose limits on certain features or restrict your access to parts or all of the Platform or Accounts without notice or liability.
This kind of quotation, for commentary, criticism, or reference, is generally allowed without obtaining permission. In the US, this falls under fair use (see 17 USC 107. In the UK and most commonwealth countries, it falls under fair dealing. In other countries there are various exceptions to copyright that will probably cover this. Even answers that do not directly quote the rule books often use information from those rulebooks to write an answer. Facts and ideas are never protected by copyright, so this is not going to be an issue. See 17 USC 102(b), which provides: (b) In no case does copyright protection for an original work of authorship extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery, regardless of the form in which it is described, explained, illustrated, or embodied in such work. As a comment by user Trish reminds, game rules are facts and are not protected, although their exact wording may be.
It doesn't work like that! If the code is not properly licensed, you can not acquire a license for it. If you don't have a license, you can not use it. Usage without a license is copyright infringement and not allowed: the copyright is with the author, and only the author may make derivates or copies or allow them to be made by licensing it. You do not gain copyright by fixing a licensing error - in fact, you commit copyright infringement if you do not have a license, and providing wrong copyright management information is illegal under 17 USC 1202
Probably not I think this question represents a misunderstanding of the linked article, and in any case of the specifically US doctrine of fair use. Fair use is always based on a part of a copyrighted work copied without authorization. If there was authorization, there would be no need to resort to the defense of fair use. The article discusses the commercial use of short sections of musical works used for commercial purposes. It points out that the idea that any use of an excerpt of less than 30 seconds is permitted is a myth. In this it is correct. While the amount of a copyrighted work used is one of the four factors to be considered in deciding wither a use is a fair use, it is not the only one, and no specific amount is always permitted. In Harper &amp; Row v. Nation Enterprises, 471 U.S. 539 (1985) The US Supreme Court held that quotes amounting to about 3-400 words from a 500-page book were an infringement, and were not a fair use, because they were the &quot;heart of the book&quot;. The linked article says that one should ask &quot;Was the work obtained from a legal source, in a lawful manner?&quot; and asserts that &quot;taking a copy from an unapproved source invalidates fair use.&quot; Nothing in 17 USC 107 says this, and I don't know of any authoritative source for such a statement. The article also says that &quot;Commercial, for-profit use is not fair use, while commentary or criticism may be.&quot; This is simply incorrect. While a commercial purpose tends to weigh against fair use, it does not preclude it, and commercial use has been held to be fair use in some cases. Even in the case of Harper &amp; Row v. Nation Enterprises linked above, fair use was seriously considered, and was not denied simply because the use was commercial. No one o0f the four fair use factors is final taken alone. I do not think the linked article is a reliable guide to US copyright law. In the case described by the question, an unreleased game has been distributed without authorization over the internet, and reviews written based on that unauthorized copy. Whoever copied the game committed copyright infringement, but a suit might not provide substantial damages unless actual economic harm could be demonstrated. (And, of course, the identity of the infringer would need to be proved.) But a review based on such a leaked copy would not necessarily be an infringement. If the review described the game, but did not quote any of its dialog or other text, and did not reproduce any sounds or images from the game, there would be no infringement. If the review did quote from the unauthorized copy, the usual fair use analysis would apply. The fact that the copy had been unauthorized would not determine the outcome. Fair use is defined by 17 USC 107. This provides: Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include— (1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes; (2) the nature of the copyrighted work; (3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and (4) the effect of the use upon the potential market for or value of the copyrighted work. The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors. Note that criticism is one of the specified purposes for which fair use is designed, and an unpublished work is still subject to fair use. If the review quoted so much of the game that the potential market for it was harmed, that would weigh against fair use, but it is hard for me to see how a mere review could do that to an interactive game. (17 USC 107(4)) is normally applied when an infringing copy serves as a replacement for the authorized version, and sales are lost as a result. I suppose it might be argued that a bad review that was a direct result of an infringement came under this provision, but it is a strech at best, and US First Amendment considerations would tend to prevent such a ruling. In short, it seems unlikely that any normal review would be an infringement, and that the game was leaked would not make it one.
No, this is not true. Copyright can be enforced selectively. You are confusing copyright with trademark. Company can lose its trademark if they aren't protecting it. All the meanwhile they can choose to ignore some copyright infringement while enforcing their rights on others with no legal problems what-so-ever. In order to illustrate the difference: for example, if someone would make a clone of Super Mario and would call their clone as well "Super Mario" and maybe even would call themselves "Nintendo", even if they have programmed the whole game by themselves from scratch and the art and music would be all different, they wouldn't be infringing the copyright but challenging protected trademarks. In your case, the naming was identical, the art and everything was too similar to the original and therefore the clone was challenging the trademark that needs constant protecting.
It is not per se necessary to license objects depicted in a video game. A 2020 court case has decided that the same rules apply to video games as to other forms of art. Just like you don't need to license every car on the road every time you take a picture of said road. Most court cases that are brought against non-licensed use of vehicles claim something other than simple use of the design, such as false implication of license or use of a trademark. Military vehicles enjoy less protection than civilian ones. The works of the US Federal Government, for one, are not copyrightable. The design of military vehicles is also a lot more functional rather than artistic. To claim copyright protection for a vehicle design, one would have to prove that the design wasn't driven by function - which is something military contractors for large projects definitely aren't hired to do. A carrier's or SSBN's shape, for instance, isn't copyrighted at all, because it's necessary for their performance. However, there are elements of real-world objects that would be protected by copyright against depiction in games. An accurate and detailed depiction of non-functional elements can be a copyright violation. Cases have been brought against artist tattoos on human models. A complex vinyl decal on a car can also be copyright-protected against depictions, but only to the extent that its depiction isn't necessary to keep the vehicle recognizable. For a big studio, licensing the vehicles can be simpler and cheaper than risking a need for a potential legal defense. It can also provide help from the manufacturer in recreating a detailed design, such as drawings and 3D models. But it is not strictly necessary.
Games can be protected by patent. You get some protection through copyright, but only on things like artwork and the precise text of the rules; someone could copy the ideas of the game with different artwork and not violate your copyright. You would need a patent in each country you want to protect it in. In general patents are expensive and complicated. Here is some general guidance on the relevant law in the USA, and how it applies to video games. If you hire a developer you can do so with a non-disclosure agreement (NDA). This is a contract requiring them to keep your ideas secret. Here is an article about using NDAs when hiring a contractor, but its a complicated area of law and you might be better hiring a lawyer to draft one for you.
