Is Udemy course material copyrighted Udemy claims that all the videos and course content are copyrighted, but does that also hold for the material of the course? For example, could someone use an app from a Udemy course as a starting point for a commercial project without acquiring a license from the course author?
Udemy claims that all the videos and course content are copyrighted, but does that also hold for the material of the course? Yes, all the material is copyrighted. Ideas are not, material and content is. it would be really useful to me if I could take a large part of that code ... I want to know if I am allowed, by the law, to use this code for commercial purposes, or is it protected as the intellectual property? Yes, it is protected, specifically it has copyright applied and you may only use it if the license it is distributed under allows you to - in some cases this may be a permissive license, or the code may be obtainable legitimately from another source under a permissive license, in which case its usable. But in many cases, it may not be distributed under a permissive license or indeed any license, and in such cases you will not be permitted to use it. The license under which the code is released depends on the individual course, and in many cases the source code repository or download site for the code for the course. Check their for a license.
You are in breach of Copyright. Plain and simple. Certain websites allow you to use the website content as long as a link is made, but the website must clearly state that. You may also use a tiny portion of the content if it falls under Fair Use, where "Fair Use" does not mean "I want to". The best thing to do is not to do it. You can't copy anybody's work without consent. If you're thinking about Google specifically then they offer multiple APIs so that you can use their content in a wide variety of ways.
Under US law your proposed use would be considered copyright infringement of the film/TV copyrights unless it is considered "fair use." The evaluation for "fair use" defense can only be done by a Federal Court judge as part of a lawsuit. The judge will evaluate the fair use defense using a four part test that evaluates: (1) the purpose and character of your use; (2) the nature of the copyrighted work; (3) the amount and substantiality of the portion taken; and (4) the effect of the use upon the potential market. This is a very fact specific inquiry, so it isn't amenable to easy yes or no answers. However, based on your description your use wouldn't be very transformative under step (1) since you are using frames from the movie unchanged, and you are using it for commercial purposes as opposed to criticism/commentary/education. Nor does step (2) seem to favor you since the anime films are not heavily based in facts that you would be reusing/publishing. Step (3) would likely favor you since the amount of material taken is very small (1 second) compared to the work as a whole. Likewise, step (4) would also likely favor you since your use is unlikely to impact the commercial market for the original film/tv show. If you intend to rely on the "fair use" defense, then you should definitely hire an attorney who can give you an individualized opinion rather than the generalities I've provided here. As to other GIF users in the App Store, they may (1) have licensed the underlying content, (2) be blatantly infringing the copyrights for the content and hoping not to get caught, (3) relying on fair use (see above), and/or (4) claim DMCA safe harbor as a message board so long as user are the ones uploading the GIF content.
Yes, assuming the material was given the standard license. You would be creating a derivative work, and only the copyright owner has the right to authorize creation of a derivative work. See the copyright FAQ for general information. The owner can file a DMCA takedown notice with YouTube and they will by policy notify you of the infringement claim and unless you file a counter-notice (you legally couldn't given the facts you're asserting), they will take it down. The owner can also sue you.
Bob is not authorized, but he may legally do so (in the US, you don't need specific authorization to perform a non-forbidden act). In creating the manual, Bob would need to avoid reproducing the questions (which are protected by copyright), and just give the answers. Copyright protection for the textbook includes not just the actual words, but also organizational structure, so Bob would need to avoid copying the structure of the exercises. As for "structure of the exercises", textbooks often have exercises for each chapter, with a clear logic to the order and content of chapters. Within the chapter exercises, there is often some rationale to the order of presentation of the dozen exercises, like starting for with simplest concepts presented in the text and moving up the ladder. In a given exercise, there my be subparts, where understanding part 1 leads you to understanding part 2, and so on. In a well-structure textbook, maybe 20% of the creative nature of the book is that artful ordering. Imposing an entirely different order on your solutions avoids copying the author's protected expression.
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.
Names of people, institutions, and events are not protected by copyright. Things that have occurred at events like math tournaments are facts, and may be recounted, in your own words, with no fear of infringing any copyright. Facts are never protected by copyright, although a particular description of facts could be, and so could a particular selection and arrangement of facts. Specific math techniques and their names are not protected either, and may be described without infringing copyright. The items you mention in the question are: video game / movie references and names No copyright issue here. common integration bee problems No copyright issue here. names of a university / math competition organizers No copyright issue here. integration techniques and formulas No copyright issue here, unless you copy an extensive description of a technique without rewriting it in your mown words.. using someone's Overleaf Latex package to format the book This depends on the license for the package, but there is not likely to be an issue. In short I think you are worrying over issues that are in fact non-issues.
Everything except the summary and the cover art are all facts; facts are not subject to copyright. The summary and cover art would be subject to copyright. You may have a fair use defence given that all you are doing is cataloguing the books.
