Copyright name of a book vs a fantasy wargame with miniatures I wrote a book which I released in April, 2015. I've just discovered there's a pen/paper fantasy game similar to dungeons and dragons with the same name that was a kickstarter back in May 2014, which was last updated April 2015 (there was about a year gap between updates.) My question is, although I didn't know it existed as my internet searches yielded nothing, I can find no listing of trademark or copyright or anything of the like, could I potentially be infringing copyright? They are similar is two regards other than the same name, that is the logo is slightly similar, and both are in the fantasy genre, although the settings, worlds, character, etc... are all wildly different. Not sure if I'm allowed to post links but can do so for someone to check if needed.
Your issue is trademark, not copyright. If these other guys use their mark (product name) in commerce but did not register it, they have an unregistered trademark which you could be infringing. Between two users of the same trademark, the first to use in commerce wins. (There is a territorial component but with the Internet, meh.) If the trademark is registered that gives them a presumption of validity. Trademark infringement is concerned with consumer confusion. If someone uses someone else's trademark in a way that confuses consumers as to the origin of the goods, that's a problem. What this means is that if I make tires with the name Sportie and someone else makes soap also with that name Sportie there is not a high likelihood of confusion. Likewise a hotel in Washington called Runner's Cove probably doesn't infringe a shoe store in Florida with the same name. Fantasy games and fantasy books sold over the Internet? Sounds like a potential problem that you might want to clear up before the second book.
This kind of quotation, for commentary, criticism, or reference, is generally allowed without obtaining permission. In the US, this falls under fair use (see 17 USC 107. In the UK and most commonwealth countries, it falls under fair dealing. In other countries there are various exceptions to copyright that will probably cover this. Even answers that do not directly quote the rule books often use information from those rulebooks to write an answer. Facts and ideas are never protected by copyright, so this is not going to be an issue. See 17 USC 102(b), which provides: (b) In no case does copyright protection for an original work of authorship extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery, regardless of the form in which it is described, explained, illustrated, or embodied in such work. As a comment by user Trish reminds, game rules are facts and are not protected, although their exact wording may be.
In general this kind of brief literary reference is not unlawful, and such things occur in both novels and commercial games with some frequency. Making such a reference a major part of the plot, such as by using a name from a previous work as a major character, particularly if other aspects of that character are also used, is far more likely to cause a problem. In the united-states this would be a matter of fair use. In general, when only a very small part of the source work is used, such a a single name; where the use is &quot;transformative&quot;, that is used for a rather different purpose than in the source work; where the use does not harm the market for the original work; and where the use does not serve as a replacement for the original, it is likely to be held to be fair use. But fair use decisions are always fact-dependent, and are made case-by-case, so it is hard to be absolutely sure of one in advance. But the kind of literary reference described in the question is very unlikely to be held to be copyright infringement.
Making the game free makes very little if any difference to the position here. There are two kinds of IP issues that could possibly be involved: copyright and trademark. Note: both copyright and trademark are civil, not criminal issues (except in very limited circumstances which do not apply to the situation described in the question). You will not &quot;face charges&quot; but might possibly be sued. If you are asked to take down such a game and comply, this might end the matter, but if an IP holder claimed that damages had occurred before the game was taken down a suite might possibly still be brought against the developer. Copyright Names, like titles and other short phrases, cannot be protected by copyright. As long as no other text from anyone else, and no images are copied or imitated, copyright is not infringed. This means that there are no copyright issues. Game mechanics and rules cannot be copyrighted, although the words of game rules can be. Therefore, fair use which is a strictly US copyright legal concept, is not involved here. Neither is fair dealing, a somewhat similar legal concept from the UK and some commonwealth and European countries. Trademark Here is the main issue for this situation. The names of individual Pokémon characters are probably (almost surely) protected as trademarks. That means you cannot use them to identify your game, or any other product or service, and you cannot use them to advertise or market your game. This is true even if the &quot;selling price&quot; is $0. The use here does not seem to be nominative use, as you are not intending to refer to Pokémon or any of its variants. You are just reusing the names. As long as you make it very clear that your game is not made by, nor in any way authorized or endorsed by the makers of Pokémon, this is probably not trademark infringement. But if the makers of Pokémon become aware of your game, they might well send you a cease and desist letter, and they might file a trademark infringement suit. Even if you were to win such a suit, as I think you might well do, it might be costly to defend. Could you alter the names to ones you invent form yourself? That might save a lot of trouble and hassle. What is the value to you in reusing the well-known Pokémon names?
The relevant law is trademark law. The basic question is whether the mark is identical or creates an unreasonable risk of confusion with the protected mark. There is no per se 30%-40% rule. I can imagine cases where changing a single letter in a long phrase turns a trademark violation into a parody or clearly different mark (see the Electric Company TV show). I can also imagine cases where changing a large part of the mark could still be infringing and confusingly similar. A parody is protected on fair use grounds in copyright law (which could conceivably come into play since this is a derivative work but would be protected since it is a parody), but in trademark law the issue is that a parody is unlikely to be confused for the original. Of course, at a fine grained level when one is looking at particular cases rather than general ideas, you would have to know which country's laws were involved, for example, where the goods would be sold.
Probably Not The creator or owner of a piece of software does not in general have any copyright over the output when others run the software, unless that output is itself a derivative work of input supplied by the copyright owner, or forming part of the software. In this case the translation is a derivative work of the 19th century original, but that is assumed to be in the public domain. SAo google has no copyright on the resulting translation. But copyright protection is only available for &quot;original works of authorship&quot;. (See 17 USC 102 in the US, and similar laws elsewhere.) A machine-produced translation is not an original work, and it is surely not then work of the author of the overall book. However, the author would still have a copyright on the book as a whole. The legal situation is no different than if the author had simply quoted a 19th century work. One may incorporate public domain works into a later work, and that later work is still protected by copyright, provided that there is enough original contentr to make the work as a whole &quot;an original work of authorship&quot;. Others may use the PD [arts, or the original from which they are taken, but not the rest of the work (beyond what fair use would allow in any case). For example, I have made a number of posts here on LAW.SE. In several,of those I quoted sections from one of the numbers of The Federalist. That 19th century work is in the public domain. Anyone else may re-quote the passages I quoted from it. But that gives them no rights to use the rest of my work, except as the CC-BY-SA license or fair use permits. So the author would retain copyright on the book as a whole. But soemoen who merely quotes or uses the translated 19th century article but none of the original parts of the book would not be infringing that copyright. I say probably in the header, because I do not have any actual case-law to cite here. It is possible that some court has rules otherwise on the subject of the copyright on the output of a software tool, but I strongly doubt it.
Expression vs Idea As I understand it, copyright applies to creative expression and not for examples rules of games. That is not correct as stated. Game rule, or more exactly the fixed expression of a set of game rule (what one finds in the package of a commercial game, or in a book such as Hoyle's Rules of Games, can be and usually are protected by copyright. What is not protected is the ideas expressed in a set of rules. These are sometimes called &quot;game mechanics&quot;. For example it is a rule of bridge that 13 cards are dealt to each of 4 players. That is a fact, and so is not protected by copyright. But the exact wording of the official Laws of Duplicate Bridge is protected. &quot;creativity&quot; vs &quot;originality&quot; Many things that might not be considered very creative are protected. US Copyright law calls not for creativity, but for an original work. The concepts of &quot;creativity&quot; and &quot;originality&quot; have a significant overlap, but are not at all the same. For example, a person might watch a baseball game and write down play-by-play account of it. That might not be very creative, but it would still be protected by copyright. But the event of the game are facts, and not protected. Someone else might describe the same game in different words, covering the same facts, and that would not be copyright infringement. Another example. A person writes a scientific paper describing in detail a series of chemical experiments and the results obtained. That is not very creative (although the design of the experiments might be). It would, however, be protected by copyright. But the facts and ideas would not be protected. Another person could desacribe the same experiments in different words, and that would not be an infringement of copyright. Merger Doctrine In extreme cases, such as a basic recipe, there is no expression temperate from the facts. In such a case the &quot;merger doctrine&quot; applies, and there is no copyright protection at all. Standards Standards, such as ISO standards, are normally protected by copyright. But the ideas expressed in them are not. And since standards are highly factual, the protection afforded to them is particularly narrow. But when one is testing compliance with a standard, the exact words of the standard may be important. A compliance officer is not likely to accept a paraphrase as a valid substitute. Standards in Laws The actual text of laws (and regulations), however (Federal, state, or local) is never protected by copyright. All are in the public domain. So when a law incorporated and reprints a standard, as is often done with fire and building codes, anyone may freely reproduce the codes as set down as part of law, even through the code has been copyrighted and indeed registered, as long as the source is the text of an enacted law or regulation.
If you create a new work that is derived from or based on someone else's work, it is a derivative work, and you cannot do so without permission from the original copyright holder. If the original work is made available under a CC-BY_SA 4.0 license, you have permission, but it comes with conditions. One of those is that you must attribute the original work -- you must say what work yours is based on and who created it. Another is that you must license your own derived work under the same CC-BY-SA license (or a compatible one). This does not mean that your work is not copyrighted -- it is. But it does mean that you must grant to others the same rights that the creator of the work you used granted to you. That is what the "share alike" or SA part of the license means. if you don't like that, you should not use a work licensed under CC-BY-SA terms to create your own work. If you publish your work but fail to grant that license to others, you are infringing the copyright of the work you used, and could be sued. Note that if you had created a compilation rather than a derived work -- for example if you created an album of images from various sources, some of them under CC-BY-SA licenses, you would retain a copyright on the collection as a whole, and that would not have to be under CC-BY-SA. But in this case you say that you used the other person's image as a background for your own illustration. That is creating an "adapted" or derivative work, i am fairly sure, and invokes the share alike clause of the license. You might also want to consider the different case mentioned in If I include an unmodified CC-BY-SA work in a book, does the whole book have to be CC-BY-SA?
