I&#39;m working on a game and want to reference some other games and movies. How much trouble could I get in with the examples below? I'm wondering what trouble a game developer could get into with making references to other things that served to inspire the dev. Suppose the dev plans to sell the game; would such references possibly cause issues later down the line I refer tpo references such as, for example: drinking bird (Alien movies) Glasses with &quot;A. Wesker&quot; written on the side (Resident Evil) A brochure that advertises The Overlook (The Shining) Newspaper talking about a shark killing &quot;Martha Vineyard&quot;, aged 75 (Jaws) One of the lockers has the name &quot;S. Henriksson&quot; (Cry of Fear) Book titled something like &quot;The favourite fellow&quot; by Charles L. Ray (Chucky)
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.
Is this legal? Generally yes, unless it unlawfully exceeds the scope of the license. Also, if it is, how can I check if it's permitted by the original store's EULA? Read the whole EULA, focusing on terms related to resale, assignment, and transferability.
Unless the game is out of copyright, e.g. chess, snakes and ladders, Go, or checkers, your software would probably be considered a derivative work of the copyrighted game and an actionable infringement. The fact that you do not monetize it is not a defense. You would need written permission in the form of a license agreement from the copyright owner to do this legally. The penalties for violating copyright laws in this way could be punishingly serious.
A statement by a fictional character is part of the fiction, and so is normally protected by copyright. A short exclamation such as &quot;You are not prepared!&quot; might be ruled to be too short and not sufficiently original to be protected if it were used separately, but that would apply just as much to a short statement that was not a quote from a character. But something like one of Gandalf's speeches on &quot;mercy and pity&quot; to Frodo in Chapter 2 (&quot;The Shadow of the past&quot;) in book 1 of The Lord of the Rings would clearly be protected. The longer and the more distinctive such a text is, the more clearly it would be protected. Whether it is put in the mouth of a character or is part of the narration makes no significant difference. Note, in a copyright sense a statement does not &quot;belong to a particular universe&quot;, rather it belongs to a copyright owner, often the author, or in the case of a video game quite likely thy publisher. As this comment by Kevin mentions, and as I should have mentioned, reproducing a short quotation from a work of fiction, particularly if properly attributed, is quite likely to be fair use. See Is this copyright infringement? Is it fair use? What if I don&#39;t make any money off it? for more specific details. See also the threads tagged fair use If a quote is used for a different purpose than the original, in what is called a &quot;transformative&quot; manner in copyright cases, then it is more likely to be held to be fair use. The smaller of a percentage of the source item the quote is, the more likely it is that it will be considered to be a fair use. The less the use of a quote serves as a replacement for the source, or harms the market for the source, the more likely it is to be considered a fair use. See the links above for more detail.
First off, the work is almost certainly not in the public domain in the US. Works are generally copyrighted upon creation or publication, but in this case the work was probably explicitly copyrighted. The fact that a work is out of print generally has no bearing on its copyright status. US copyright law changed several times in the last century. The 1985 copyright year means the board game was probably published then, and it's since it's a Disney copyright it's a corporate work, which would give it a copyright term of 95 years, meaning that it should be covered under copyright until 2080. See this factsheet on copyright from the US Copyright office. Works Created on or after January 1, 1978 For works made for hire and anonymous and pseudonymous works, the duration of copyright is 95 years from first publication or 120 years from creation, whichever is shorter International laws will vary, but many countries adhere to the Berne Convention, which means that international laws will probably be at least similar. Either way, the work isn't very old from an intellectual property perspective. Fair use is an exception to copyright law that allows portions of copyrighted works to be used without permission or compensation in certain circumstances; academic or scholarly use is one of them. Generally, your use of the work has to be the minimum necessary amount to serve your purposes, and cannot harm the commercial value of the work. (The fact that the work is out of print may help with the latter.) The problem with fair use is that it's always determined on a case by case basis. The only way to know for sure if a particular use is fair use is to wait for the copyright holder to sue you and then make a fair use defense in court. I was going to suggest that you discuss this with the editor of your journal, but re-reading your question it looks like you're planning to publish to a personal blog rather than an academic journal. In the end, it's up to you (or your attorney, if you choose to hire one) to analyze the relevant legal concepts and rules and decide if and how much of the work to use.
Copyright infringement requires copying. The inventor could very reasonably invent a device without any reference or even knowledge of the artistic depiction in the Portal games. If the inventor hasn't copied anything, they aren't infringing copyright. Also, with respect to 2d depictions of 3d objects, only architectural drawings are protected in that way: https://en.wikipedia.org/wiki/Copyright_in_architecture_in_the_United_States With respect to your patent question, Valve hasn't publicly disclosed how to make a Portal gun, so an inventor of a Portal gun would not be blocked from patenting it. You can't get a patent without describing how to actually make the invention.
A bankrupt company's assets are transferred to its creditors. This includes intangible assets such as trademarks, copyrights, and other intellectual property. Whoever ends up with the rights to the game can continue to market and distribute it, or use legal means to prevent others from doing so.
if I directly purchase this custom content... As a general rule, &quot;intellectual property&quot; is very different from tangible property - arguably, &quot;intellectual property&quot; is a misnomer. Trying to apply concepts from property law (such as &quot;a thing has a single owner, who can do anything not illegal with it as they please&quot;) is fraught with danger. You would generally not &quot;purchase content&quot;, but rather purchase a license for the content, allowing you to do various things. One of those things might be to &quot;curate/edit this collection of recordings and present it publicly as an art project (probably just online)&quot;. Another might be to &quot;to sell or otherwise profit from this&quot;. All that depends on what your contract says. In an ideal world(?), contracts would all be detailed enough to leave no uncertainty about what is allowed and what is not. In the real world, a bunch of SMS can form a contract. For instance, the following is a contract: A (version 1): Hey B, could you send me a clip of you waving at the camera? I will pay $10 for it. B: sure ...but it’s not clear what A and B agreed as to what the clip would be used for. Saving and viewing on A’s device, probably yes; putting it in fullscreen in the next blockbuster movie, probably no. Showing it to A’s friends, putting it in an art project? That’s getting dicey. You might have heard about &quot;work for hire&quot; granting full copyright control to whoever pays for the work to be created. In the united-states, the above exchange does not explicitly designate the content as work-for-hire, as would be required by 17 U.S.C. § 101 (&quot;...if the parties expressly agree in a written instrument signed by them that the work shall be considered a work made for hire&quot;). Here’s a better SMS contract: A (version 2): Hey B, could you send me a clip of you waving at the camera? I will use it to make an art project, collating many such clips, and publishing that on the internet. I will pay $10 for it. B: sure Here there’s no question that B agreed with the proposed use. On the other hand, it’s likely than a different use would be deemed a copyright violation - the contract was proposed by A and should be understood as limiting A’s right to use the clip to exactly what they said they would do. If they wanted it to say something else, they could have sent a different SMS (see contra proferentem).
