Is a Masters thesis in the public domain? Is a Master's thesis submitted to the University of California Berkeley in the public domain (i.e., can be shared publicly by a person in USA on the internet without asking anybody's permission)?
No. The general policy of the University of California is that students and faculty retain the copyright of scholarly works they create. So the thesis is copyrighted by its author (unless the author has since transferred copyright for some reason). However, if you contact the author and ask politely, there is a good chance that they will give you permission to share it.
united-states in US copyright law, there are no &quot;classifications&quot; of copyright. A protected work is a protected work. There are a few special provisions for architectural and sculptural works, and quite a few for musical works, but different types of web transmission or hosting make no difference with regard to US copyright law. I don't know what difference such classifications might make in the law of India.
If I make a working prototype and upload it on youtube will it prevent others from getting a patent on the idea? Generally yes. If the core information is accessible to the public, it becomes &quot;prior art&quot; and cannot be patented anymore by someone else. That includes you. Depending on local legislation, you have a small time window to apply for a patent (after disclosure) but if you don't, it's public domain and everybody is free to use it. If it's mainly code, you may be able to upload to Github and attach a license to it but that offers only limited protection. Globally? That depends on local legislation which there are too many of, to answer this here.
17 U.S. Code § 107, which governs fair use in the US, says (emphasis mine): 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 commercial/educational use is part of only one factor. Even if that factor is in your favor, it may not be fair use, and even if it isn't in your favor, it might be fair use. Because fair use is determined on a case-by-case basis, we can't really say whether your use is fair use, with or without the donations. That would be the sort of thing you'd ask a lawyer about to get real legal advice on your particular case.
Wikipedia and you likely have no contract. If you don't have to click "I agree" to access the data, its likely there is no contract. Therefore this is a pure IP law question. The ONLY IP law issue that I see is copyright. The DATA is not subject to copyright. Only the expression of that data. So copying the html and selling that IS potential copyright infringement. Copying the data in some other format and using that is not. Finally, even if you do copy the full html (i.e. full expression), this MAY be licensed by their terms of use (as you suggested they have licensed some content). That is a more particularized legal question that I can't answer here.
You misunderstand the nature of copyright. Holding copyright allows you to decide how the work can be copied: there is no obligation on you to publish it if you don't want to. After your copyright expires you don't have to publish it either: the only thing that has changed is you can no longer prevent anyone making a copy. The lost works of Aristotle are in the public domain - if you can find them you can make as many copes as you like.
You need to check what license the library comes with. The fact that you want to create a public domain program doesn't give you any rights to any library. So read the BSD license and see what it tells you whether and how you can use the library. For example, if you used a GPL-licensed library, you could not put your program in the public domain legally.
I'm going to focus on one part of your question, because I think it is informative to the entire question: "By publishing those data in a copyrighted book are they now in the public domain?" Insofar as copyright is concerned, the "facts" are simply never copyrightable. What is copyrightable is the expression of the fact. So you publish a book and it contains many facts. You retain copyright over how you expressed the facts, meaning the word choice, format of presentation and so on. The discussion of this point always leads people to ask the following two questions: What if the "facts" are closely related to the way they are expressed? For example, a phonebook contains "facts" about phone numbers. The individual numbers are not subject to copyright. But if the way they were organized was clever (i.e. not merely alphabetical) the presentation may be copyrighted. Doesn't that line get blurred? Why doesn't "the presentation order" count as a "fact?" It does get blurred! And courts use nuanced case law and judgment to figure out which side of the line a given thing is. However, one backstop is that if AN EXPRESSION is so closely related to the IDEA BEING EXPRESSED that the IDEA cannot be otherwise expressed, then then the EXPRESSION is not subject to copyright protection. To answer your specific questions: The book is subject to copyright. The facts in the book are not. Someone else could publish a book with the same measurements so long as they are expressing the facts with sufficient difference from the original. I'm not familiar with CUSIP numbers. However, there are two things to say here. (A) it sounds like you are describing a contractual relationship between the people who have the numbers. This is not governed by copyright; it is governed by contract between the parties. If these numbers could be treated as a "trade secret" they might be protected IP in that way. But given that they are likely circulated at least a bit, they don't seem like candidates for "trade secret" protection. To your question, "what is the effect of one person leaking?" If "trade secret" law was doing any "work" here... then yes, the trade secret would be undone once the information was public. But like I said, its likely this is actually all about contracts not intellectual property protection. (B) The "facts" of "which number is associated with which instrument" is likely NOT subject to copyright at any time. The specific numbering code COULD BE copyrighted, but in reality is almost certainly TOO CLOSELY tied to the IDEA being expressed to be copyrighted. Could the number be expressed otherwise? If not, then its likely not protected by copyright. -- Big take away here: You seem to be confused about the concept of "facts" getting into the public domain. That's not exactly what copyright is about. Copyright would protect the expression of facts. An expression can become public domain if it is sufficiently old or if the creator designates it as public domain work. But simply "putting something out there" does nothing to alter the copyright status of the thing.
