It is true that character classes are stock characters? It is true that character classes from a game are considered &quot;stock characters&quot; and therefore excluded from copyright protection? If they are not considered &quot;stock characters&quot; what makes them (somewhat) free to use? The concept of character classes was introduced with Dungeons &amp; Dragons in the 1970s. Examples of character classes found on video games and tabletop RPGs: cleric, druid, warrior, paladin, rogue, shaman and mage.
Arguably not (or, the example terms are not restricted by copyright, but not for the reasons given, which means this protection may not extend past the examples given in all cases). The protection for &quot;stock characters&quot; comes from the &quot;Scènes à faire&quot; doctrine, which protects elements that are elementary and near-required to be part of a genre. For example, a fairy tale is &quot;obligated&quot; to start with &quot;Once upon a time&quot; and end with &quot;And they lived happily ever after&quot;. Character classes, by virtue of being character classes, do not qualify under this doctrine to me, simply by virtue of being &quot;character classes&quot;. What matters are: a) the terms used for the classes are generic b) there is prior art to any claimed copyright, with uses of such terms in fantasy fiction stretching back at least hundreds of years and predating, for example, modern English. Note that the above is not universal to all character classes. For example, if you had classes whose names that directly related to various other copyrighted works IP (e.g. &quot;Jedi Councilor&quot;, &quot;Yogo Wardmaster&quot;, &quot;Grey Warden&quot;, &quot;Aes Sedai&quot;, &quot;Asha'man&quot; &quot;Eversor Assassin&quot;), those could still be infringing copyright.
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.
Your client is confused about how copyright law works (at least in the United States and virtually every other country I've ever heard about copyright in). If I were guessing, they read something like this from the United States Copyright Office: The copyright in a derivative work covers only the additions, changes, or other new material appearing for the first time in the work. Protection does not extend to any preexisting material, that is, previously published or previously registered works or works in the public domain or owned by a third party. and figured that because it's a derivative work, the copyright only covers the additions and changes they make, and there's no copyright protection for the original work. This misunderstands the law: the original work still has its own copyright (assuming it hasn't expired), and permission from the holder of the copyright on the original work is required to create that derivative work in the first place*. The copyright on the derivative work is separate—that is, both copyrights exist in parallel. * Some exceptions, such as fair use, exist, but would be unlikely to apply to the situation you describe.
In Germany, there is no concept that corresponds directly to public domain. You automatically hold the Urheberrecht (~ copyright) for all creative works that you make, and it can't be given up or transferred (§29 UrhG). The work only enters the Gemeinfreiheit (~public domain) 70 years after your death. You can however license Verwertungsrechte (economic usage rights). When you make creative works in the course of employment (see §43 UrhG), your employer automatically gets the Verwertungsrechte necessary in the context for the work, which is typically an exclusive right (no one else, not even you, can use the work). Your are not in an employment relationship with your school, so it has no rights to your works and cannot prevent you from publishing them on copyright grounds. When you see advice on the internet to check with your school first, that is U.S.-specific advice. Since you're still a minor (7–17), you only have limited capacity to enter contracts or legal transactions (bedingte Geschäftsfähigkeit). While you are able to make transactions involving your own means (e.g. buying something with your pocket money) or make transactions that are only to your benefit (such as accepting a gift), other transactions are schwebend unwirksam (~ pending ratification), until your parents agree. The relevant law is in §107 and §108 BGB. This is a problem with open source licenses. If you publish software under a license, this license is schwebend unwirksam. Someone might start using the software under the license. But then if your parents refuse ratification, the license would be invalid, and everyone would have to stop using your software and destroy any derivative works they made. This is a bit of a problem, especially since open source licenses are otherwise assumed to be irrevocable. So if you want to offer a license (including open source licenses), please give legal certainty to the recipients of the license and ask your parents for their consent first, possibly even in writing. Per §107 BGB, the license you offer with their consent will be valid.
Copyright never protects ideas or processes, it only protects expression: words, images, and sounds, some of which may describe ideas. But when a work is nothing more than a translation of an idea into words, with no independent originality -- when almost anyone would use more or less the same way to describe the idea, then the work will not be protected by copyright at all, as it is not considered an "original work". Computer code that implements an algorithm often falls under this rule. It is my belief that the code shown in the linked SE thread would fall under this rule, and would not be protected by copyright at all. If this is correct, then anyone may share such a program with no copyright concern.
No. Copyright does not have exemptions for obsolete works, use with credit, or non-commercial use. Depending on the purpose for the distribution, this could be fair use, but it is unlikely that a court will consider this fair use when the only reason is for other people to be able to play games. Perhaps you could try contacting Adobe; it's possible that they will give you a license to distribute the Flash Player. This isn't directly relevant to the legal aspect of copying Adobe's Flash Play, but to answer the underlying issue of legally playing Flash games, perhaps you/others could try Gnash, a libre reimplementation of Flash. I have not used it, but apparently Gnash can run some Flash software without using Adobe's player.
A document, or an image of a document, created using a font would not be considered to be a derivative work of that font. If it were, our system of licensing fonts would need to be significantly different. In any case the part of the license which reads: [This license] allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. It specifically permits such use of the fonts. By &quot;derivatives&quot; the license seems to mean modified versions of the fonts, which it permits the licensee to create and use subject to certain restrictions. This seems to be confirmed by the license text which says: The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives. The plain meaning of this is that derivatives of the fonts are used to create documents, not that they are documents themselves, and that in any case &quot;any document created using the fonts&quot; is not subject to the license restriction.
Monopoly is a trademark of Parker Brothers. You would need to get permission to use that trademark. The artwork of the game is copyrighted and cannot be duplicated without violating that copyright. In general, the labels meaning phrases like "Go to Jail" and "New York Avenue" are probably copyrighted and some court decisions have decided that labels are a copyrightable element. However, there is some gray area. The game mechanics are not copyrightable and can be duplicated. What this means is that if you clone the game and use new labels (like new property names and card titles) then you are probably fine. You would have to make a novel board design. If you clone the game, but use the game's labels, then you could potentially lose in court. Of course, remember that corporations will sometimes sue just to intimidate people, even if they have a losing case. Just because your clone is non-infringing doesn't mean they won't sue you. It costs them money to sue people, so if your clone is obscure or not used by many people it could fly under the radar and be ignored by the company. If your clone was a success and became widely used, that would significantly increase the chance you could get sued. In most cases a company will threaten infringers before they sue them, because it is a lot cheaper to threaten somebody than sue them. Therefore, you could make your clone and just plan on discontinuing it if they threaten you. Of course, there is a small risk they would sue you anyway. If you made no money then you are probably safe because it would be a lot harder for them to argue that you commercially damaged them if you made no money.
