I made a software version of a semi-popular board game for free. Is that legal? All the code is 100% my own - I made it for practice, and to showcase my abilities to potential employers. To facilitate this, I want to release the code open source on GitHub. I credit the game's designer in the opening menu, and use the title in my title. Surely since I'm not running adds on the site I plan to host it on, or monetize it in any way, I should't be in any legal trouble? Thought I'd ask first. What kind of licence would I use?
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.
Software qua property is protected by copyright *perhaps patent, in some jurisdiction). The general rule is that whoever creates the thing (book, song, software) has the exclusive right to the thing. If an employee of Company 1 writes software for Company 2, that employee might (rarely) hold the copyright, but typically that scenario would involve a "work for hire", where the employee is hired by Company 1 to do such tasks as part of his duties with Company 1 (which might then be given to Company 2). This would then be a work for hire, and the copyright is held by Company 1. If the actual author was an independent contractor, he would hold the copyright – see Community for Creative Non-Violence v. Reed for analysis of the subtle nuances in making that determination. The concept "work for hire" which crucially involves the "employee" relationship would not be applicable to Company 2 paying Company 1 for a product, and as long as the actual author is an employee of C1, C1 has not created a "work for hire" in the legal sense. Without some explicit disposition of copyright, Company 2 is in a sketchy position. Since C1 holds copyright, they must grant a license to C2 so that C2 can legally use it; or, C1 must transfer copyright to C2. This does not happen automatically, and (if C1 does not want to remedy the situation after the fact) C2 would need to take C1 to court to force a resolution to the situation. At that point, the issue would be what C1 implicitly promised, even though they didn't put it in writing. It is likely that the initial exchange was along the lines "Can you make us a program that will do X?", and the answer was "Sure, that will cost Y", and then "Okay, go ahead, looking forward to the product". The courts would not simply say "Well, you didn't explicitly require a license, so you don't get to actually use the software that you paid for". However, it's a somewhat open question whether the court would order a license (of what nature?) or a transfer of copyright. The disposition would depend heavily on the facts of the case (what was said, what C1 actually did, what kind of business they are, what did creating the work involve...).
Recall the basic principle of copyright law, as detailed in 17 USC 106: The copyright holder has the exclusive right to make copies; prepare derivative works; or distribute copies by sale, rental, lease, or lending. Other people can legally do these things only if they are given permission by the copyright holder, typically via a license. (Remember, the literal meaning of the word license is permission.) Often, the copyright holder will require a prospective licensee to accept various terms and conditions before the license will be granted. If there is &quot;no EULA&quot;, or if there is one but the purchaser has not agreed to its terms, then the purchaser has not been granted any such license, hence does not have permission to do any of the things listed above. If they do so anyway, it is illegal copyright infringement and they will be liable for damages. To use a firewall analogy, copyright law is &quot;default deny&quot;. So let's take your questions one by one: Do they own the software? US law has no concept of literally owning software. The closest thing is owning the copyright, which the purchaser certainly does not. It still belongs to the vendor that wrote the software (or whoever they may have later transferred it to). Can they legally alter the code of the program they purchased? No, that would be preparing a derivative work. The copyright holder has not granted them a license to do that. (There are some exceptions for purposes such as reverse engineering and interoperability, see 17 USC 1201(f)). Can they legally redistribute it No; again, that is the exclusive right of the copyright holder, and the purchaser has not received their permission. or transfer ownership? Maybe, if the first sale doctrine applies. Its application to software is complicated. The user has a better case for being able to sell the software if it exists as some tangible object which is transferred (physical media, pre-installed on hardware, etc). Can they legally modify the code of the program for others who have also purchased the same package? No, that would be preparing a derivative work. Can they take that software and install it on a secondary machine? No, that would be making a copy.
This would be infringement. It generally doesn't matter that you're giving things away for free. Keep in mind that the point of these laws is not only to prevent third parties from making money off the creator's ideas, but also to protect the creator's ability to make money. If you're providing free knock-off Winnie the Pooh products, that cuts into the market for the creator's legitimate products.
You can license the use of your IP only for certain uses, for example (most commonly) &quot;non-commercial&quot;. The general template of permission is &quot;You have permission to ___ as long as you ___&quot;. What the user is permitted to do, in your scheme, is something along the lines of &quot;only distribute the output in this manner&quot;, or &quot;not distribute code developed with this tool anywhere else&quot;. It's up to you to prove that someone violated that condition, if they did.
Negotiate a licence Of course, your chance of doing so are not good - computer game companies routinely pay millions to use trademarks like this (and they usually get exclusive rights) and that’s probably out of your price range. Stopping you doing what you want to do without paying for the privilege is effectively what trademarks exist to do. If the usage was incidental and clearly used Star Trek IP to identify Star Trek products, like the usage in The Big Bang Theory TV show, then that’s OK. However, your usage is using Star Trek as the core of the product and that’s not OK. Others have suggested that the trademark owner may not pursue you - that’s unlikely. Unlike copyright, trademarks that are not defended can be lost - this trademark is worth billions, they will happily spend tens of thousands to grind you into the dust.
It seems that you don’t understand what parody is. If you do understand, please explain how it’s even possible to parody computer code. What you can do with “open source” code depends on the licence the copyright holder(s) release it under. For some very permissive licences you can do what you suggest, for most, you can’t.
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.
