Is it legal to copy a software license text from other companies to write my own? I am writing a software license myself before I hire a lawyer. Is it legal to copy a software license text from other companies to write my own? I could not find anyone talking about the copyright of the software license itself. But many software licenses have the same text. I found this post (Is it legal to copy a website&#39;s terms of use?) but not sure if this applies to a software license
Software licenses are protected by copyright, meaning that you need the author's permission to copy them. One way to get permission is to buy a license, since many of them are for sale. Sometimes (e.g. CC licenses) a license to copy the license is granted. You can also read and understand what is in a license, and use that knowledge to write your own. This is different from copying the license, since what you are extracting from the existing licenses is the ideas, not the specific expression.
Q1 and Q2 are definitely not copyright violations. Copyright protects original expression. Your questions are yours; the only things you are using are the names, and copyright doesn't cover them on their own. The quotation in Q3 might conceivably come under copyright. However in practice it is very likely to be fair use (unfortunately nothing is definitely fair use until a court rules on it, but I can't imagine a short quotation in a quiz being an issue).
They have copyright in their additional text, and possibly in things like their visual design choices (fonts, layout etc). They may also have introduced a few deliberate typos to detect any literal copies from their version (rather as mapmakers add a few imaginary features to their maps). None of this creates any rights to the original text. You are still free to produce your own copies of the original text. Just get it from some other source so you can be sure not to include anything of theirs.
Numbering is for the sake of clarity, and is not intrinsically required. If you refer to a section, you need a way to say which section you mean, and a vague description like "up there where I talked about copying" is insufficient. You can refer to a section by a title, if you need to refer to sections within the contract, as long as your titles match what you refer to them as (and you don't have two sections called "Your Rights").
This is going to depend on several things. First of all, do you have a lawful, licensed copy of the SDK? My understanding is that Nintendo only licensed the SDK to selected game companies. If what you have is an unauthorized copy, you do not have the legal right even to use it. If what you have is properly licensed, then you do. Or is what you have an unofficial SDK created by someone other than Nintendo? Secondly, what does the license agreement that comes with the SDK provide? Does it require developers to register with Nintendo? If it does, you will need to comply. Nintendo cannot prevent others from writing programs designed to run on their hardware. But they can control who uses their development software, if they choose to. You cannot reproduce in your game any of Nintendo's copyrighted software (or anyone else's) without permission. That applies even more strongly if you intend to sell the software. But you can use any development software for which you have a valid license in whatever ways its license permits. I would expect this includes creating games. It would include selling games that you create that do not use any of Nintendo's code, unless there is a specific provision forbidding that in the license agreement.
It's a contract violation if you're under the EULA. It may be a contract of adhesion, but such "clickwrap" contracts been found to be acceptable and enforceable in software EULAs out of necessity. However, there may be some limits. If you're not under the EULA, as you argue, then you lack a license to use the software at all and it's an outright copyright violation and/or a theft or misappropriation of the software. Whether or not you can be sued depends in part on what you do with it — if you don't release the material or otherwise cause damages then there's not much to sue for... Added for clarification: to answer the framing question, supposing neither contract or copyright applied, one could be sued in tort or in equity (i.e. for unjust enrichment).
Your answer (in the US) is the same as feetwet's answer to the earlier question you linked: Is it possible to protect a business idea? - Law Stack Exchange. You can't copyright an idea for software. You can't copyright an idea for a pitch of a TV show or an episode of an existing TV show (Google "copyright TV series idea"). You can't copyright a combination of ideas for a TV show, i.e., one that uses software as the plot line or in the screenwriting or taping process. Once you do the work - develop software or write a script - you have legal protection (which varies, depending on jurisdictions). You can copyright the software you have developed. You can copyright (or commonly register) the TV script you have written. Or, in the US and other jurisdictions, your work is copyrighted as soon as you produce it.
You cannot do this through any established public license that I know of, but you could write your own. The model would be any educational use or non-commercial use license, such as CC NC licenses. The main challenge is defining the excluded classes of usage. That is why you should engage an attorney to draft this for you. I don't think there is any point in adding a $5M penalty clause. You offer a separate paid license for individuals who do not want to comply with the particular terms of your license, and set the fee to whatever you want. Saying that you're gonna fine violators is a bad idea because penalty clauses are illegal. Instead, the standard approach is a liquidated damages clause, where you state what a reasonable estimate of your damages would be. In the case of software that is available for purchase, illegal copying of the software obviously results at least in the cost of the software qua lost revenue as damages. Plus shipping and handling.
