Copying an existing HTML page and use it, is that against any copyright law? I found an online calculator that determines certain parameters I need. However, that calculator can be improved and more information added. I have improved it and now I want to make it public on my new website, however, I don't know anything about online copyright as this is my first attempt to do something similar. I have copied the HTML page and javascript and customized it to make it better. On the original online calculator and downloaded files, there isn't any copyright claim. Does it mean I have the right to use these newly modified files and publish the improved calculator on my website?
There doesn't need to be any copyright claim for there to be copyright protection. The protection is given automatically whenever someone authors a work. If you make money off of your improved version, the owner of the page may sue you for royalties. The only way to avoid this is to ask him for permission, or to create your page without using any of the source code of the original page.
This may well be infringement, but I agree that you should start by reaching out to the instructor. You don't want to pay a lawyer if the matter can be be adjusted peacefully. In the US there is a special limited exemption to copyright for "use in classroom instruction" which might apply in such a case. I am not sure if there is a similar provision in Canadian copyright law. But the instructor is likely to change his practice if you notify him of your objection, even if he has the technical right to use the photo. At least it is worth finding out. If he won't, then you can always consult a lawyer.
Content posted to the web is usually openly accessible to all (unless protected by a password, paywall, or similar restriction). But that does not mean it is freely copyable by all. Such content is protected by copyright in just the same way as if it had been published in a book of essays by various contributors. Unless the copyright holders (who are likely to be the original authors, but might not be) give permission, or an exception to copyright applies, copying such content would be clear and obvious copyright infringement, and any copyright holder could sue for damages. Permission could be given by publishing the content under a permissive license, such as a CC-BY-SA license, or any of many other available permissive licenses. Or a would-be reuser could find the copyright holders and ask for permission. If the holder cannot be found or identified, or does not respond, then no permission has been granted. In the US the main exception to copyright is fair use. See this answer and other threads with the fair-use tag here for more on fair use. Since the question seems to contemplate using the whole of the posted content, since it might well damage any potential market for that content, and since the use does not seem to be &quot;transformative&quot;, nor used for criticism or comment, a finding of fair use for this situation seems unlikely. But Fair use findings are very much fact-driven, and the exact facts do matter. Thus I cannot be at all sure whether a court would find this toi be fair use or not. In other countries there are a variety of exceptions to copyright, and I have not come close to reviewing them all. But none of the ones I know of seem to apply to the situation described in the question. Many are narrower than the US concept of fair use. I fear that without permission, copying this content would be infringement. However, it would not be infringement to create a site that includes a link to the existing content, and a summary or description of that content, along with new content, including comments on the old, with brief quotes to indicate what is being commented on.
Yes So far so good. This is a copyright violation but it is probably fair use - certainly there is case law permitting a copy of a backup digital asset to be made so I don’t see why a similar argument wouldn’t work with backing up a physical book. Clear copyright violation. Alice can rent out the original under the first sale doctrine but the ‘backup’ is not so protected. It’s not fair use because it’s use is commercial, the work is a type of work the author expects to profit from, the entire work has been copied and the use is deleterious to the market i.e. the renters are less likely to buy an original - it falls foul of all four factors of the fair use test.
No. The images are copyrighted, and you are using them in a way that would leave you with virtually no argument for fair use. The factors for fair use are set out in 17 USC 107, and they indicate that the courts would reject your use: The purpose and character of the use, including whether it is of a commercial nature or for nonprofit educational purposes: There's no indication that your use would be for nonprofit or educational purposes. The nature of the copyrighted work: Works of fiction and art are highly creative works at the heart of the policy for copyright protection. The amount of the portion used in relation to the copyrighted work as a whole: You are apparently copying entire images, though I suppose you could argue that each image is just one small portion of a larger book or website. The effect of the use upon the potential market for or value of the copyrighted work: You are trying to create a board game, putting yourselves basically in direct competition with the makers of D&amp;D. I generally prefer a pretty liberal interpretation of what constitutes fair use, but this just has virtually nothing that would make me comfortable arguing in your favor.
Whoever "derived" the illegal derivative work most likely has copyright in his derivations, unless they are not worth copyright protections. Say I take the Harry Potter books and add a few chapters and try to sell it - that's copyright infringement of course, but I have the copyright on these additional chapters. However, I don't have the right to allow you to copy the derived work. And even if you have the right to copy the original work, you don't have the right to copy the derived work because it is a different work. I could extract my changes, and allow you to take them and do with them what you like. You could then create an illegally derived work yourself. I couldn't sue you, but the original copyright holder could. To the comments: One, a work and a derivative of the work are not the same, so even if you have the right to make a copy of a work, that doesn’t give you any right whatsoever to copy a derivative work - they are not the same work. Two, the copyright holder has the exclusive right to control copying and the creation of derivative works. If the copyright holder doesn’t want derivatives to exist, then creating them, copying them etc. is always copyright infringement.
is contract text itself subject to copyright? What are my options? It largely depends on the originality of your contract. C &amp; J Management Corp. v. Anderson, 707 F.Supp.2d 858, 862 (2009) points to multiple references against preclusion of "a copyrightable interest in a contract". But you would need to prove that your competitor copied "original elements" of your contract including "a minimum degree of creativity and originality required to support a valid copyright". See Donald v. Uarco Business Forms, 478 F.2d 764, 766 (1973). Your post provides no information that would help identifying or ruling out this issue in your matter. Without realizing, you might have paid dearly for boilerplate language that your lawyer copied from somewhere else. Indeed, there is so much regurgitation and copy/pasting in the legal "profession" (judges included, as is notorious in judicial opinions they release and in the similarities --verbatim-- among the procedure law of many, many U.S. jurisdictions). That regurgitation is not bad in and of itself, though, since what matters is the expeditious administration of justice and the protection of your rights, rather than obtaining creative expressions authored by some lawyer. You might end up wasting valuable energy and money if you went after the competitor for something like this without first assessing the extent of originality in your contract. Focus instead on the much more detrimental fact that your competitor "plays dirty in general".
The following answer is based on US-law. I am not a lawyer; this is not legal advice. If the book you read is in the public domain* you should be fine. Otherwise what you are doing is copyright infringement and probably not protected by fair use**. One of the rights granted to copyright holders is to control derivative works, and transference to different mediums, which is what your recordings would be. Under US law, whether an instance of copyright infringement is fair use is evaluated on a case-by-case basis, weighing four points: the purpose and character of one's use the nature of the copyrighted work what amount and proportion of the whole work was taken the effect of the use upon the potential market for, or value of the copyrighted work In my non-lawyer evaluation, point 1 depends on what you do in your video (unless you monetize your Youtube video, in which case it is likely to be decided against you), but if you are merely reading the book out aloud, it is unlikely to be in your favor (although it may not be against you as an &quot;educational tool&quot;). Point 2 depends on what is being read, with a informative work (e.g. a textbook) being more likely to be fair use than a creative work (e.g. a novel). Point 3 depends on how much and what proportion of a work you use; since you are presumably reading a whole book, this would most likely be ruled against you. Point 4 would almost certainly be decided against you, as you are essentially creating an unauthorized audiobook. In summary, you can read a book aloud. You can record your reading of it for your personal use. You should NOT upload it to Youtube, or other sharing sites. *Note that different countries have differing rules on when a book enters the public domain, and since the internet crosses borders, multiple rule sets may apply.
