Is it possible to use creatures from an RPG (like Dungeons and Dragons) in writing a book without infringing on copyrights? I am planning on writing a book that happens in a universe separate from Dungeons and Dragons universe but I want to have a character be a Kenku. I know that they are copyrighted for use in other RPGs. But what about in books? Would I just have to change the race name, but can I keep all the attributes? The Kenku is going to be cursed to look like a human. They talk by mimicking things they hear. The main character is trying to fix the curse but doesn't know that the Kenku is a Kenku. The main character thinks the Kenku is a human cursed with some type of impaired speech which makes it hard to understand him. How do I find what I am able to use and what I can't use? Would the be in the Open Gaming License? Or somewhere else?
Derivative work The Kenku first appeared in Dungeon Magazine 27 in 1991 and appears to be an original work as far as I can tell. It, therefore, enjoys copyright protection until 70 years after the author dies - it seems unlikely that the author died before 1950 so the copyright has probably not expired, AFAIK, the author is, in fact, still alive. Your usage is what is known as a derivative work and making derivative works is one of the rights that copyright grants to the copyright holder. You can't do it without permission unless you have a fair use defence: you don't. If you call your Kenku a duck; it's still a Kenku This is the inverse of the well-known duck test much beloved of philosophers and employment-law judges but equally relevant to copyright-law judges. Changing one (or several or even many) aspects of a copyrighted work is still copyright infringement. You are free to write something inspired by the Kenku but once "it looks like a Kenku, swims like a Kenku, and quacks like a Kenku, then it probably is a Kenku".
Most games have a TOS to playing that include provisions such as sales of in game items through out of game currencies (i.e. real world money changes hands for digital product or account). I believe Pokemon does have this as part of the TOS which could get you and potential customers banned from competition and possibly the modern online trade features, but am unable to look at the current TOS to verify. It should not be hard to find such a document and read for yourself.
Those posts are talking about making a modified copy of a copyrighted work. The key word is copy. You are not making a copy. Copyright is not about how a physical embodiment of a copyrighted work is treated. You can burn a book and shred a newspaper. Neither of those actions is making a copy. Also, cutting up a newspaper and pasting a picture on your wall has nothing to do with any “derivative works” issue.
Yes, you do. But you should not base your claim primarily on copyright, but just on the license contract you agreed to. It's typically much easier to prove that a party did not fulfill its part of a sales contract (here: Pay the agreed amount) than to prove violation of a copyright you own. Also, you then only need to sue one guy, and not care about every platform your game might be hosted on. This is particularly difficult here, since they have not done anything wrong. It's not their fault that the publisher didn't properly pay the programmer. They (very likely) got their copy of the game legally. For details, you should consult a lawyer. We can't give you detailed legal advice.
They have copyright in their additional text, and possibly in things like their visual design choices (fonts, layout etc). They may also have introduced a few deliberate typos to detect any literal copies from their version (rather as mapmakers add a few imaginary features to their maps). None of this creates any rights to the original text. You are still free to produce your own copies of the original text. Just get it from some other source so you can be sure not to include anything of theirs.
One cannot use the works of others unless one of the following applies: The copyright holder has given permission, usually in the form of a license, often explicit, but sometimes implied. The work is not protected by copyright. This can happen in several ways, but the most common is that the work is old enough that copyright has expired. In the US, works older than 1927 are currently out of copyright. So are some others, the rules are a bit complex. In many countries, if the author or creator died more than 70 years ago, the work is out of copyright. In some countries this is a different number, between 50 and 100 years. This is not likely to apply to a file distributed with current software. If an exception to copyright applies. In the US this would most likely be fair use. In the UK it would probably be fair dealing. In other countries there are a variety of exceptions that might apply, including personal use in some. AS a comment by Jen points out &quot;use&quot; here refers only to those rights protected by copyright, such as making and distributing copied, making nd distributing derivative works, and the like. (Displaying and publicly performing seem unlikely to apply.) Now lets consider the specific situation, and which if any of the reasons for lawful use might apply. License or other permission. There is no explicit license. Since the program is distributed to be run, there is an implicit license to make the sort of use of the file needed to run the program. If the documentation describes how to employ the file as part of running the program, there is almost surely an implied license to employ it in that way. There is not, however, permission to make copies unless that is needed to run the program. There is surely not permission to make derivative works of the file or distribute copies to others, even if you do not charge anything. Expired copyright This pretty clearly will not apply. Fair use This might apply, or might not. There isn't enough info in the question to tell, not even to make a good guess. If any use would be non commercial, that helps fair use a bit. If the use would be for a different purpose than the one the developers used it for, that helps fair use a lot. If the use of the file harmed the market for the program, or served as a substitute, that lean against fair use. without knowing what the file is, what it does, and how it might be used, one really cannot weven guess.
Copyright protection is about certain acts, and not about relationships between products. Copyright law says that the creator of an original work hold the exclusive right to copy and to authorize creation of derivative works. Copyright law does not say that anybody can freely create derivative works as long as they are different to a certain extent. So if you take an original Mario and modify it a teeny bit, that is a violation of copyright; if you take an original Mario and modify it hugely, that is a violation of copyright. Degree of similarity is relevant on some cases when the factual question arises whether the allegedly-infringing work is based on some protected original. This is most obvious in music cases, where all baroque music has some similarity to all other baroque music, all death metal has some similarity to all other death metal, and so on. There is not a legal quasi-statutory standard for measuring substantial similarity in music. The scientific underpinning of such a standard would be based on (weighted) combinatorics and the idea that there are only so many tunes possible (that would be a huge number, until you get to the "within a genre" condition). It seems obvious (by your "admission") that the derived works are based on protected works, so Nintendo's permission is required to legally create such works. However, you do or would hold copyright in your unauthorized derived work. Without a trail of evidence such as a SE question pointing to the connection, the derived images might be hard to connect to the originals. In addition, you may be able to avail yourself of a "fair use" defense, in case you get sued by the original creator. Factors favoring such a defense are the insubstantiality of the copying (a small portion) and the "transformativeness" of your creation.
No. GPL works are copyrighted (as are most creative works basically everywhere in the world, as soon as they're created, whether or not the author does anything about it), and copyright is what gives the GPL "teeth". Without copyright, you would generally be able to duplicate and distribute programs without any kind of license or permission from the author. Copyright law restricts your ability to do those things. The GPL is a license, which means it's a grant of permission. It says that you may copy and modify and do other things, provided that you comply with the other provisions set out in the license. Quoting from the GPL v3: You are not required to accept this License in order to receive or run a copy of the Program. [...] However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. So if you were to distribute some GPL-licensed software in a way that didn't comply with the terms of the license, the legal framework that would allow someone to sue you to stop you doing that would be copyright law.
