Can I use the term &quot;tweets&quot; for posts at my own site? Can I use the term &quot;tweets&quot; for posts at my own site? And if I put the word &quot;tweet&quot; in quotes?
From what I can see on the USPTO registry, &quot;tweet&quot; is still not trademarked for the purposes you're talking about. Twitter has been working to secure that trademark, but I can't find any record of them having actually secured it. Just the same, I'd predict that using it will get you at least a cease-and-desist letter, and possibly a lawsuit. Whether you'd win that case seems to be a very open question, but that presumes you have the resources to litigate.
There is ample reason to conclude that "non-commercial" would include a church, as well as advocating a political cause or candidate. The hard part of "personal". In the context of (Canadian) bankruptcy law, it can mean "non-business use"; in the context of "personal use property", it can be "A type of property that an individual does not use for business purposes or hold as an investment. In other words, property that an individual owns for personal enjoyment". US tax law takes "personal purposes" to refer to non-business purposes. But in the context of copyright (especially music downloading / copying), it is taken to refer to the use of or by an individual. Distributing free copies of a protected work does not get legally sanctioned due to the copying being non-commercial. The alternative term "private" is much clearer, in identifying "just you", but is probably avoided in this kind of context so as to avoid the wrong inference that you can only play Pokemon in the privacy of your own home. So the slightly less clear term "personal" is used instead of "private" especially in copyright-related contexts. "Personal" and "private" are not exactly the same, but when it's about use, I don't see any difference, and I think there is no question that use to attract to a church or political candidate is not "private", it is public. Since the license does not define "your own personal purposes" and there is not an existing crystal-clear definition of "personal purposes", the phrase could be given its "ordinary (plain) meaning". Of course, plain meaning has to give way to contractual intent, so we have to figure out what the parties intended. Except, you don't have a contract with Niantic, but still, plain meaning surely has some place in the law of licenses. At this point, in a lawsuit, both sides would hire an expert witness like a linguist or English teacher to make the case that a church or other non-commercial non-private use is / is not included in the meaning of "personal purpose". A silly argument could be made to the effect that if you personally have an interest in doing something then it is a personal purpose (if specifically commercial, it would be precluded by the term "noncommercial"). What makes this silly is that everybody does things for personal purposes (even acting in a way that benefits others, since you do so for the personal reason that you should do so), and thus "personal" would not mean anything. That is, "personal purposes" does not mean "whatever motivation or interest you personally have". You can also gain a certain understanding of what "personal purposes" means by looking at similar licenses. In the context of academic publishing, authors are typically granted license to copy "for personal, professional, or teaching purposes". Professional purposes and teaching purposes are things that the person has an interest in, so by mentioning these things separately, we must conclude that "teaching" is not a "personal purpose". And so: I would conclude that a court could find that using a product to support a political campaign, philosophy, or religion, is a "public" purpose, not a "personal" purpose. At the same time, at least as I understand it, a lure module is a thing that others besides yourself personally can see (I admit, I don't go), which implies that the purpose of the thing is not entirely private. In addition, there is a fair amount of buzz out there about how a lure could be good for business, which is (1) clearly in contradiction of the license terms and (2) clearly a golden opportunity for Niantic, perhaps in a few weeks after everybody gets hooked and then they will offer non-personal licenses. Their license terms also say that you will not "use the Services or Content, or any portion thereof, for any commercial purpose or for the benefit of any third party or in a manner not permitted by these Terms". I would say that that definitively says "No don't do it", and it also means that you can't be nice to a neighbor. So what they literally say and what they really intend are probably completely different things.
Yes you can. The pieces of information you are going to include are facts. Facts are not copyrightable. The names will be trademarks but you will not be pretending to have any connection with them, so just using them for reference is fine.
This is not &quot;unfair competition&quot;. You are allowed to ask people for their views and take them into account in designing software, even with the specific intent that it compete successfully with existing software. In the US you have a protected right to do that under the First Amendment. If the chat site where you asked is run by the developer or owners of the app, they can ask you to avoid such question there, and even ban you from the site if they choose, because it is their site. But if you went onto a public site (like Stack Exchange, say, or Quora) the app owners would have no right to insist that you not ask for such opinions. The degree to which the design or interface of an app or other software may be protected against imitation is a complex one, and depends on the country involved. But widely known and used features such as a 'like' button, message threading, or a comment section are almost surely not protectable. Listening to users of existing simile products and getting their ideas on what works well and what is lacking is generally a good idea, and is in no way &quot;unfair&quot;.
The question as worded implies that if something is a parody it is automatically fair use or allowed in US copyright law. This is a myth. First of all, in a copyright context, the term "parody" is somewhat limited. In that sense, a "parody" is a new work which comments on the original (often but not always by mocking or ridiculing the original). A mere alternate version which modifies the form of the original, perhaps humorously, but not to comment on the original or perhaps on much of anything, is not a parody. A new work which modifies the original to comment on something else, but not on the original, is a satire. Of course many works may be both parodies and satires in this sense. See this law.se Q&amp;A for extensive quotes from Suntrust Bank v. Houghton Mifflin Co 268 F.3d 1257 (The case of The Wind Done Gone vs Gone with the Wind) and discussion of what is and is not a parody in US copyright law, and when a parody is fair use. A parody, because it comments on the original, will often be found to be a fair use of the original. But not always. The full four-factor analysis must still be done, and the results are never certain until a court has passed on the specific case. See this law.se Q&amp;A for more on fair use. I can't tell from the question whether the modified song is truly a parody in the sense used in copyright law. If not, it probably isn't fair use, although it might be for other reasons. By the way, a song written for a television show or video to be distributed commercially is a commercial use, even if a non-profit corporation is involved, and even if there is an educational purpose. Note that fair-use is a strictly US legal concept. Even if something is fair use under US law, it may be copyright infringement under the laws of some other country.
In reviewing the NBA.COM site Terms of Use at: NBA.COM Terms of Use It appears that your proposed usage violates the site's and the API's terms of use. Specifically this: The Operator maintains the Services for your personal entertainment, information, education, and communication. Where the function is available, you may download material displayed on the Services to any single computer only for your personal, noncommercial use, provided you also maintain all intellectual property, including copyright and other proprietary notices contained on or associated with the materials. You may not, however, distribute, reproduce, republish, upload, display, modify, transmit, reuse, repost, link to, or use any materials of the Services for public or commercial purposes on any other Website, social media platform, or otherwise without the written permission of the Operator. Modification of any materials displayed on the Services is a violation of the Operator’s intellectual property, including copyright and other proprietary rights. This appears to me to preclude you from using their site or APIs as a data source for your service. You may, however, wish to try to obtain permission from the &quot;operator&quot;. Keep in mind that while the factual information may not be copyrightable, the use of their service is controlled by the terms of use license.
Assuming Chegg own the copyright, then they can restrict the activities that copyright protects The statement you quote is no more or less than the rights granted to them by copyright law. Basically, it's their stuff, they get to decide how you can use it. However, that does not necessarily mean that the uses that you have nominated are prohibited. For that, we would have to look at the specific fair use or fair dealing exemptions to copyright protection where you are. It's likely that both of your usage scenarios would meet fair use and probably fair dealing (which is harder to meet). You may also find that, buried somewhere in those massive terms of use, is something that deals with this directly.
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.
