Where is the line between idea/expression dichotomy? Just wondering where idea become expression. Let's take The Lord Of The Ring as an example, if i want to write a boook about two alchemist heading to a tower in order to destroy the ring of evil, would it be a rip of idea or expression? FYI no, i'm not gonna write a book about it. :P You can answer me using Harry Potter as an example if you want, just interested in understanding where the line is.
Expression is tied up with fixation. Copyright subsists in a work that is fixed in a tangible medium of expression from which they can be reproduced, perceived, or communicated. 17 USC 102 This expression is protected, not the idea. However, copyright infringement can occur even when there is not an exact copy. First, courts use a substantial similarity standard to determine if infringement has occurred. Second, when a character or plot is sufficiently developed, taking that character or that plot can be infringement, even if not expressed in the exact same manner. "We do not doubt that two plays may correspond in plot closely enough for infringement [...] the less developed the characters, the less they can be copyrighted; that is the penalty an author must bear for marking them too indistinctly." Nichols v. Universal Pictures Corporation, 45 F.2d 119 (2d Cir. 1930) Some characters or plot elements are so common to a genre that they are either not considered "original" enough to get copyright protection, or can be taken by others without being considered infringement. This is the scènes à faire doctrine. "Stock scenes and hackneyed character types that "naturally flow from a common theme"—are considered "ideas," and therefore are not copyrightable. But as plots become more intricately detailed and characters become more idiosyncratic, they at some point cross the line into "expression" and are protected by copyright." Suntrust Bank v. Houghton Mifflin Co., 268 F. 3d 1257 - Court of Appeals, 11th Circuit 2001 See Amanda Schreyer's An Overview of Legal Protection for Fictional Characters: Balancing Public and Private Interests for many more cases and examples of the idea-expression dichotomy in action with respect to fictional characters.
Not very novel What you are talking about is a derivative work. This is arguably the most famous example: It's an interesting example because Leonardo da Vinci did not have copyright in the original but Marcel Duchamp and Francis Picabia do have copyright in the derivative. Even though the changes are physically small, they are enough. A crucial factor in current legal analysis of derivative works is transformativeness, largely as a result of the Supreme Court's 1994 decision in Campbell v. Acuff-Rose Music, Inc. The Court's opinion emphasized the importance of transformativeness in its fair use analysis of the parody of "Oh, Pretty Woman" involved in the Campbell case. In parody, as the Court explained, the transformativeness is the new insight that readers, listeners, or viewers gain from the parodic treatment of the original work. As the Court pointed out, the words of the parody "derisively demonstrat[e] how bland and banal the Orbison [Pretty Woman] song" is. For an author to have copyright in the derivative they must: Meet the (low) threshold of originality for copyright to exist. Make their derivative lawfully - either because they have permission or because their use falls under an exception to copyright like fair use or fair dealing. However, they do not have copyright in the original elements. For example, I could take the Mona Lisa and give her different clothes, a different background or a hat I will not be infringing their copyright. If I give her a different style of moustache? However, there is an issue with "I have copyright on the contents of the post" when you don't. Even if your work is derivative, you do not have copyright in the original parts and do not have the right to licence them. So, for example, this post is a derivative work of the Wikipedia page linked to above and I have copyright in my original contributions because: They meet the threshold of originality I have permission to make the derivative either through the Wikipedia licence or because my use is fair use. I can give Stack Exchange a licence for my work but I cannot give them a licence for the original work including, for example, the image and quote above. So, someone could quote my entire answer subject to the licence or fair work, but they couldn't copy just the image or quote.
No, it means you can't copy it. By default, the copyright to a work is owned by its creator, and nobody else is allowed to copy it, or create derived works, without their permission. That permission can be granted by a license. "License unknown" doesn't really tell us anything, but it certainly isn't clearly granting you permission. So you don't have permission to copy, and thus you cannot. You would have to seek permission from the copyright holder. See also If no licence is distributed with an application/source code, what license applies by default if any? (Some jurisdictions do allow for "fair use" exceptions, which allow you to copy a work without permission. You haven't said what jurisdiction you are in.)
You don't just want to ask, you are required to obtain a license (or in other terms: the OK of the author*). Your game is based on a book. That makes your game a derivate work. Under berne convention, any signer state has to make sure that the author* has the right to authorize any derivate. That includes translations, films, or games. Without a license, you violate copyright law. It doesn't matter if your game is free. To stay safe, you need to obtain a license. Quite some authors would be happy to cut a deal, license or guidelines for fan-projects. As an example, the late Sir Terry Pratchett OBE has specific guidelines on what is ok and what not. Ask your author* about these questions and consult a Lawyer! Only then make your fan project! * This means the author, their estate or whoever they assigned their rights in the work to. Some examples: For that teenage wizard in a private castle charter school that'd be a certain J.K. Rowling. For those hairy-halflings running all over the continent hunted by orcs that'd be the J.R.R. Tolkien-Estate. And for those space wizards using blades from solid light that'd be The Walt Disney Company or one of their subsidiaries.
Probably not. It sounds like you've copied the complete work without any meaningful transformation. You've reduced the market for the original work by hosting your own copy. The fact that your purpose &quot;is to share the information&quot; doesn't really do you any good, as that is also the purpose of the original work. You're almost certainly outside fair-use territory. If you're looking for a &quot;kosher&quot; way to do this, the generally accepted practice is to link to the article and either paraphrase or excerpt the most relevant portions. That said, the fact that this piece came from a university may help you out. If it's a public university, it may be that its &quot;news&quot; articles are actually public records and not protected by copyright.

Is it ok to copy the game concept and even with mostly similar content like "fighting", "building houses" etc ? Yes, but ... I should also mention that pretty much my whole User Interface is based on the User Interface from "Parallel Kingdoms" Is copyright violation. Ideas are not protected by IP law. The tangible representation of those ideas (art, words, layout, format etc.) is protected.
As for plagiarism, that is not a legal concept, so he can define plagiarism however he wants. It certainly isn't, under any definition I have ever seen on Earth and I have seen many (it has to do with "claiming someone else's work as your own"). As for copyright, a set of questions is (potentially) protected by copyright. If they are copied from somebody else's book of questions, then the book author (or publisher) holds copyright. Let's say that QM invented the questions, such as "What is the Turkish word for Janissary?", "What is the most prominent feature of Jannissary garb?" and so on. Then that set of questions, when put down in fixed form, are protected by copyright, and cannot be copied without permission.
While &quot;clause&quot; has a specific definition in linguistics, that is not how it is used in laws and legal documents. These terms have no standard definition for legal writing. Documents or legal codes that use both generally use &quot;article&quot; to mean a larger division than &quot;clause&quot; does. In discussion of the US Federal Constitution, for example, the largest divisions are called &quot;articles&quot;, each of which is divided into several &quot;sections&quot;, and each section generally contains several &quot;clauses&quot;. Some of these are actually grammatical clauses, being part of a sentence with a verb and a subject, while others might be called paragraphs in ordinary prose. A given document or legal code should ideally define which terms it will use for its parts, and which contain which others. This can be done in whatever way the drafters wish, but it is desirable that it be clear. In addition to the terms you have mentioned, terms often used include &quot;subsection&quot;, &quot;subsubsection&quot;, &quot;title&quot;, &quot;paragraph&quot;, &quot;subparagraph&quot;, &quot;chapter&quot;, &quot;part&quot; and &quot;division&quot;. These are not used consistently, and I have never seen a single document or code that uses all of them. The Us law code is divided into titles, each of which contains sections. In some of these sets of related sections are grouped into chapters. Sections may have subsections or paragraphs. In my experience smaller contracts or business documents rarely use &quot;articles&quot; and some just use &quot;section&quot; for any named or numbered part of the document. Usually titles or section headers are explicitly stated to have no legal effect, and the division into sections or other parts is simply to facilitate reference, and does not have legal significance. Whether a provision is called an article, a section, or a clause will not normally change its legal effect. However, where one part of a document refers to another part, such as &quot;as specified in section 23&quot; then the reference will be found in and only in the designated part, and will not be looked for in some other part.
