Fair use of Tweets There are many personalities that use Twitter to promote themselves, and are active on the site. If I sell a product that quotes or reproduces these tweets is it fair use? Let's assume that we are talking about tweets of 140 chars or less.
The length of a literary work doesn't determine if its use is fair use. Copyright does not cover names, titles of works, catchwords/catchphrases/advertising slogans etc. or lists of ingredients (like in a recipe or chemical instructions), however, the procedure can be copyright. The work must also be original. If the tweet copies something that already exists then there is no copyright in the tweet - if the thing that is copied has copyright protection then the tweet itself may be a violation. That said, assuming that the Tweet enjoys copyright protection, the owner will be the author: presumably the owner of the Twitter account. For anyone else to legally use it, the use must be either: Licensed by the copyright owner Fair use (USA) or Fair Dealing (most everywhere else in the English speaking world) For Item 1, the Twitter terms of service say: You retain your rights to any Content you submit, post or display on or through the Services. By submitting, posting or displaying Content on or through the Services, you grant us a worldwide, non-exclusive, royalty-free license (with the right to sublicense) to use, copy, reproduce, process, adapt, modify, publish, transmit, display and distribute such Content in any and all media or distribution methods (now known or later developed). In case you don't know what that means, Twitter gives you this plain English summary: Tip: This license is you authorizing us to make your Tweets on the Twitter Services available to the rest of the world and to let others do the same. So, you can get permission from the copyright holder or from Twitter. Well, Twitter has given permission: Except as permitted through the Twitter Services, these Terms, or the terms provided on dev.twitter.com, you have to use the Twitter API if you want to reproduce, modify, create derivative works, distribute, sell, transfer, publicly display, publicly perform, transmit, or otherwise use the Twitter Services or Content on the Twitter Services. Providing you use their API, you can "reproduce, modify, create derivative works, distribute, sell, transfer, publicly display, publicly perform, transmit, or otherwise use the ... Content ..." Therefore, fair use/dealing considerations are irrelevant.
This seems to be a mix of question about law and a meta-question about this site, but I'll treat it as an on-topic question about law. The author of a question, or answer, owns the copyright to their contributions, and they can re-publish to their heart's content. Any user who posts here grants a license to SE and other users to use content posted here, so I don't have to ask you permission to quote you. As part of the permission granted by SE to use this website, you have agreed to &quot;follow the rules&quot; set by SE. There are many rules, some spelled out more clearly that others. For example, if you post a question, you indirectly agreed that your content can be upvoted or down-voted. Certain content can be &quot;closed&quot; and deleted, when the content is deemed to violate the rules in particular ways (is spam, porn, abuse, or judged to be poor-quality). Judgment (on different matters) can be rendered by community managers, moderators, or other users. The agreement is here, see especially here. If we take the post that you linked to, it is quite possible that it was deleted because it is not a general legal question, in violation of the acceptable use policy. If you want a historical analysis of your particular case, it should be asked on Law Meta.
There are several things going on with Akinator and their use of trademarked names and characters. If you look at akinator.com Legal Notices it says: 2 – Copyright – Reproduction rights All the content of this site falls under French and international legislation on copyright and intellectual property. All rights reserved. Reproduction in whole or in part of this website, in any form or by any means is strictly prohibited without prior authorisation of the publications director. All products and trademarks mentioned are property of their respective owners. (emphasis mine) The fact that they mention that all trademarks belong to their respective owners is good, but it's a formality. What it appears the site really relies on for use of trademarked characters is what's called Nominative Use, which is a type of "trademark fair use." The product or service cannot be readily identified without using the trademark (e.g. trademark is descriptive of a person, place, or product attribute). https://en.wikipedia.org/wiki/Nominative_use Akinator has to use the names and trademarks to identify those names and trademarks. Akinator could possibly be sued to establish their type of fair use is not valid in their case, but it's probably not worth it for the companies to pursue. And, most companies would rather people use and see their trademarks in a marketing and money-making fair use sense rather than sue to stop their use. See In the US, when is fair use a defense to copyright infringement? for a full description of Fair Use. Now, when you get to the "answer" part of the game, you will see a "copyright" link. Part of that resulting page says Displayed pictures are accessible from the web. It is Elokence's policy to respond to notices of alleged copyright infringement that comply with applicable international intellectual property law and make the necessary changes. In respect of Elokence's Intellectual Property Policy, Elokence operates a complaints procedure accessible via the form below. So the company has given itself a further bit of protection by only using images on the web they can link to (at least in the web browser game; I don't know about the App), so that means the image is already "out there", uploaded by someone else, and Akinator can claim they didn't upload it. And, further, there is a contact form for trademark holders to send DMCA takedown notices for their work. It's a belt and suspenders approach to the use of trademarks in their game.
Go to court and find out There is no doubt that humming a tune and recording it (or performing it in public) is a derivative work - a right reserved to the copyright owner. Whether it is fair use depends on the specifics of the case. From the tweet, we simply don’t have enough information, however, at a guess, it is probably not fair use. Fair use in law is Notwithstanding the provisions of sections 17 U.S.C. § 106 and 17 U.S.C. § 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: the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes; the nature of the copyrighted work; the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and 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. Most people miss “for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research,” - if you aren’t doing one of those things then you start behind the 8-ball when yo move to the 4 factor test. Note that the “criticism, comment, news reporting,” etc. must be about the copyrighted work - I can’t use your copyrighted work to, for example, parody a politician unless you are that politician. Many people have completely the wrong idea about what copyright infringement and fair use actually are, in part because the use of music on YouTube is allowed, not because it’s fair use but, because YouTube was smart enough to negotiate and pay for a permissive licence with music producers. For a full explanation, see this video.
Can he use another commercial product that is copyrighted, e.g. a map of a location (the map is a political map and has nothing to do with trees), for his tree research purposes, if such a map won't be part of the book he works on? Yes. Copyright protects particular expressions of ideas and knowledge, not the ideas and knowledge themselves. Using a map for research purposes when the map or a modified version of it does not appear in the final work does not make the final work a &quot;derivative work&quot; covered by copyright.
You are in general correct, KBurchfiel. A code snippet such as import math; or For i := 1 to 10 print i; has no originality, and is not protected by copyright. A post eplaining the meaning an usage of such a snippet might well be original enough to be protected by US copyright, indeed it probably would. But the code on its own would not be. Anyone could read such a post, and if s/he understood it, use the code snippet and not be in violation of copyright, not compelled to place the entire program in which such a snippet was used under a CC-=BY-SA license. The creative commons people would prefer that a CC license not be applied to a publication that is not protected by copyright, and if it is so applied it is legally meaningless. But they have no legal way to enforce such a preference. A stack exchange post that consisted of nothing but such an uncopyrightable code snippet, with no explanation r discussion, might well be downvoted or even deleted. But that is a matter of site policy on what is a useful answer, not a matter of copyright. Using an excerpt from a copyrighted work so small that the excerpt alone would be uncopyrightable, would probably be fair use under US law, and might well be fair dealing in UK law. Something that is fair use does not compel the reuser to abide by the terms of a CC license, because those terms apply only when the content could not be reused without the CC license's permission. However, a code snippet does not need to be very much more original than the above examples before it becomes copyrightable. Whether it can be used via fair use rather than via the CC-BY-SA license is a very fact-based decision (the usual four-factor analysis is spelled out in 17 USC 107).. But if the snippet can be rewritten to express the same concepts but in a different expression, then there is no copyright issue, and again the CC license will not apply. If the snippet is complex and original enough to be copyrightable (a fairly low bar) and it is re-used unchanged, under conditions where fair use does not apply, then the CC-BY-SA license's terms must be complied with for the use to be legal. That is several &quot;IFs&quot; however. The exact details of a specific case will matter in such cases, there is not one rule for all snippets, all posts, or all programs.
The standard for fair use of trademarks is as follows: (1) the product or service in question is not readily identifiable without use of the trademark (2) only so much of the mark as is reasonably necessary to identify the product or service is used (3) use of the mark does not suggest sponsorship or endorsement by the trademark owner. I think you might run into a problem with (1). In other words the trademark owner would argue that you could have used fake trademarks to satisfy your product description needs, so you are using their trademark unnecessarily.
It depends on the nature of the quote. Quotes from Buddha, Aristotle and Lincoln are out of copyright. Otherwise, the two basic questions are: who put that quote in fixed form, and is copying it "fair use"? If for example you happen to be at a political rally where a politician makes a noteworthy extemporaneous quote, you could be the copyright holder, because copyright law protects the person who first puts the work into fixed form. (If he's reading from prepared text, the speech writer or his employer would hold copyright). You can also quote small bits from any source, such as "Don't think about your errors or failures; otherwise, you'll never do a thing". It would not be "fair use" to chop up a novel into a sequence of 2-3 sentence quotes. This assumes that you manually assemble the quotes from legal sources, such as a print copy of "The Martian". Whether or not you can legally pull the data from an online source depends on the terms of service for that site. That lets out brainyquote as a source, so check the TOS for whatever source you get the material from.
