How does public domain work? If a cartoon is in the public domain what does that mean exactly? For example these are all in the public domain: Mighty Mouse: Wolf! Wolf! Betty Boop And Grampy Private Eye Popeye suppressed duck daffy duck Bugs Bunny - All This and Rabbit Stew Does that mean I can play the video's as much as I want to any size crowd I wanted? Could I charge money to watch the videos? What about the characters in the videos, could I make a new Bugs Bunny or Might Mouse animation on my own? If something is in the public domain does that mean all the parts of that thing are? If I wanted to use Popeye or Betty Boop or daffy duck in a video game could I?
Public domain means that there is no (longer) copyright in the given work. This means that all rights associated with copyright are not controlled by anyone and there is no way to run afoul of copyright laws (note that in some countries a true &quot;public domain&quot; doesn't exist). Assuming you're correct that these works are in public domain, answers to your particular questions are: Does that mean I can play the video's as much as I want to any size crowd I wanted? Could I charge money to watch the videos? Yes and yes. If something is in the public domain does that mean all the parts of that thing are? This kind of begs the question. A work in public domain has no copyright in it. If one of its part has copyright, then it's not really public domain is it? What about the characters in the videos, could I make a new Bugs Bunny or Might Mouse animation on my own? If I wanted to use Popeye or Betty Boop or daffy duck in a video game could I? Copyright isn't your issue here, trademarks are. The characters are most likely trademarked, meaning you generally can't use them in your own works without licensing.
Ideas (methods of playing, game mechanics, strategy, goals) cannot be protected by copyright. But any part of a creative work can. So, no copying of drawings, patterns, images, sounds, or the element. I suppose copying the software code is not an issue here, but it can, obviously, also not be copied. And nothing in your game can look like someone's else trademark.
Yes, you can do that, assuming that the pictures are really in the public domain (i.e. due to their age, and not only claimed to be). But you probably shouldn't, but you'll probably want to add a label to the images anyway (what it depicts, who the original painter is, etc). So adding a &quot;public domain&quot; tag to each image shouldn't be a big issue. You can do that on a separate page as well, giving the source for each. Note that while using pd images does not create a copyright violation, even if you blatantly say that you created them yourself, it could still be considered plagiarism. When writing a science book or even a thesis, this could get you into trouble.
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.
Under US copyright law, all works are protected by copyright except for US Government works. The concept of "public domain" is not legally well-defined, and is used colloquially to refer to government works, works whose protection has expired, works available to all, and works not copyrightable (such as scientific laws or old software). Under older copyright law, releasing a work without the copyright symbol effectively put the work in the public domain. One can simply say "I dedicate this work to the public domain", and that is typically taken to be enough. CC0 purports to do this (using more words). However, as far as I can tell, author rights under European law are so strong that it is simply impossible. Releasing works into the public law has to be consistent with other aspects of the law. If you grant an perpetual exclusive right to copy and distribute to a publisher, their right does not go away on your death (a right which they would not have with a real public domain work). A problem is that an author who makes such a dedication (a bare license) could revoke the license and reassert their copyright. They could be estopped from making that argument. As property, your heirs would inherit the copyright and could (try to) revoke the license. Presumably the courts would not allow them to pursue ostensive infringers. Nevertheless, your plan is neither trivial nor bullet-proof.
You are framing it wrong. It is not that "they have put a barrier" to public domain information, it is that they have added an additional source of that information. The new source has a barrier, yes, but that does not prevent you from accessing the same information elsewhere. If you own a copy of some public domain data, you are not allowed to prevent other users from accessing other copies (by claiming copyright infringement or the like); you cannot even prevent people from doing copies from the copies you did provide them. But you are not forced to allow other users to access your copy. Consider the logical conclusion if that were the law. The moment that you downloaded some public domain file into your computer, you would be forced to give access to your hard disk from the internet, isn't it? Would you need to leave your home door open if you happened to have a printed copy of the text there? Of course, there is a need to discriminate between "public domain" (without licence) and "not public domain but open licence" (BSD, CC, GPL, etc.). In the later case the licence could be tailored so that the work could appear in archive.org but that it would be illegal to provide it with the business model of Academia.edu1. But that would be possible only for works not in the public domain. 1 To be decided by a judge on the basis of the wording of the licence and jurisdiction.
My question is, because I am not making any income from the distribution of the game, would the use of the copyrighted music fall under Personal Use? There are some &quot;private use&quot; exemptions in Australian copyright law but they have some fairly narrow conditions. These exemptions are fairly narrow because the point of copyright law is not to prevent you from making money with someone else's intellectual property but to protect the other person's ability to make money with it. If Alice writes a song and Bob distributes it free of charge, Alice loses revenue. Similarly, it is Alice's right to decide whether that song should be included in a freely available open-source software product, and her right to decide whether to allow that use without charge or in exchange for a license fee.
Because of the nature of online distribution, &quot;watching&quot; a show involves copying, so you need permission from the copyright holder to make those copies. You get permission indirectly, when you access a show via a legal licensee who has permission to distribute. A pirate site has no permission, therefore you cannot legally sub-license the show, and in so doing, you infringe copyright. The issue is not whether you &quot;paid for it&quot;, it is whether you have obtained proper permission. Under copyright law, a rights holder can simply arbitrarily deny you permission to copy the work.
