Is license required to sell songs replayed on a virtual instrument? Would it infringe copyright to replay the Star Wars theme on a virtual accordion app and sell the song as a lesson to play? If not would it be allowed if its free? I couldn't find anything on the internet in regards to replay copyrighted material on a virtual instrument/app.
I don't believe you could do that without infringing copyright. The Star Wars theme is a copyrighted piece of music, and creating a transcription of it would be considered a derivative work. Only the copyright holder can authorize such derivative works. Cost doesn't factor into it at all. https://en.wikipedia.org/wiki/Derivative_work
You may have issues if you take their content wholesale. Even if they freely distribute them, they still retain copyright. As such, they absolutely can claim copyright. Whether they will or not is another question. Your best bet around this is Fair Use doctrine. You can take a part of their work (e.g: a single question) and do your video based on how you work out your answer, with your video mainly focusing on the 'working out' part (thus satisfying the 'educational purposes' part)
Is it ok to copy the game concept and even with mostly similar content like "fighting", "building houses" etc ? Yes, but ... I should also mention that pretty much my whole User Interface is based on the User Interface from "Parallel Kingdoms" Is copyright violation. Ideas are not protected by IP law. The tangible representation of those ideas (art, words, layout, format etc.) is protected.
It's complicated You still own your own posts First off, you own everything that you originally created. Posting it on Stack Exchange doesn't affect your rights to your own content. Incorporating suggestions If you copy any of the text from posts that were created by others, you must comply with the CC BY-SA license. The exact version will depend on when the content was posted, and can be viewed by clicking the &quot;Share&quot; link or viewing the post's timeline via the clock icon on the left. Currently, new posts are licensed under CC BY-SA 4.0, which requires you to (basically) provide attribution with the creator's name, a link back to the content, and an indication of whether changes were made. A more detailed description of the exact requirements is here. You would also be required to license the work that you incorporated it into under the same license. However, game mechanics aren't copyrightable. If you merely used mechanics suggested in the posts without actually using the actual creative expression (for instance, names or description text) from the posts, you would not be required to provide any attribution or use any particular license, because you didn't use any copyrightable material from the post. A thank-you would still be nice All that said, it's still a nice thing to do to provide some sort of informal thanks to those who provided valuable assistance, even when you're not legally required to do so.
Yes, such a site can be created without infringing copyright Facts about the game are facts.They are not protected by copyright. Criticism of, and comment about the game, is an activity protected by the US First Amendment. Making such comments is very likely to be fair use under US copyright law. In general the author of a work, such as a book or a game, or the maker of a product, has no right to grant or withhold permission to discuss or comment on the work. This is true not only under US law, but also in the law of most countries (perhaps of all countries). The name of the game might well be protected as a trademark. But that does not allow the trademark owner to prevent discussion of the game, clearly identified by the name of of the game. As long as nothing is being sold or rented, or advertised for sale or rental under that name, and there is no attempt to claim that the site is sponsored or approved by the trademark owner, and there is no likelihood of confusion, there is no trademark infringement. This is true under US law, and under the trademark laws of most other countries. A wiki is a specific technology. It can be used for community discussion, or for a company's internal documentation, or for any of many other purposes. Wikipedia has popularized this technology. Not all community discussion sites are wikis, however, nor are all wikis for community discussion. Just as not all novels are books printed on paper, and not all books are novels. In any case, setting up a wiki about a topic such as a game, a movie, or a novel does not require permission from the owner or creator of the game or of any trademarks associated with the game or work. The same would be true for a discussion forum about such a game or work that is not a wiki. If a wiki uses excessive quotes from game dialog, or uses the game's logo without permission, or reproduces other game assets, such as character art, maps, and the like without permission, that might be copyright infringement.
Musical compositions can be, and if recent almost always are, protected by copyright. This is separate from the copyright on a recording of a performance of the work. If you reuse a musical passage, the new work may be a derivative work, that is a work based on an earlier work. Or an extended musical quotation could be considered to be copyright infringement. If this is in the united-states the use of a section from a previous work might be considered to be a fair use (fair-use). This is a specifically US concept in copyright law, although several other countries have a concept of fair dealing which is somewhat similar, although narrower. Whether a use is a fair use is an inherently fact-based determination. There is no clear and simple bright line for what is and is not a fair use. US law (17 USC 197) specifies four factors which are to be weighed by a court in considering the matter: The purpose and character of the use. If your use is commercial that weighs against fair use, but does not at all preclude it. This factor also includes whether the use is transformative or not. A transformative use is one that takes the part used for a very different sort of purpose than the original. Parodies are normally transformative, for example. A quote for purposes of commentary and analysis, or criticism is normally transformative. Transformative uses are more likely to be considered fair uses. The nature of the copyrighted work. Creative works such as fiction and music are more strongly protected than works such as textbooks and news stories. This probably weighs against fair use in the case described. The amount and substantiality of the portion used in relation to the copyrighted work as a whole. If only a short section of a longer work is used, that weighs in favor of fair use. However very short quotes can still fail, to be held to be fair uses. In Harper vs Nation a quote of about 300 words from a 500 page book was held not to be fair use because it was &quot;the heart of the book&quot;. The effect of the use upon the potential market for or value of the copyrighted work. A use that significantly harms the market value of the original, or serves as a replacement for it, weigh strongly against fair use. This was a major factor in Harper vs Nation. Each case of claimed fair use is evaluated by looking at all four factors, and the specific facts of the case. From the description in the question, such a use might well be held to be fair use. Musical quotations often are. But there is no way to be sure unless a court evaluates the specific case. A lawyer specifically experienced in not only copyright law, but copyrights on music, might be able to give more specific advice. Or you could, of course, seek permission from the copyright holder, quite likely the original composer or artist. If you get permission, there is no further issue. There might be a charge, but when the use is minor, and has no commercial effect, the charge might be small or even zero provided that the source is acknowledged.
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.
A &quot;cover&quot; does require a license, but it a special license – a compulsory license, sometimes called a &quot;mechanical license&quot;. Under 17 USC 115, upon payment of a fixed license fee, you can obtain a compulsory license (meaning that the author cannot withhold permission) as long as you don't create what would be a derivative work for music, that is you adhere to this restriction: A compulsory license includes the privilege of making a musical arrangement of the work to the extent necessary to conform it to the style or manner of interpretation of the performance involved, but the arrangement shall not change the basic melody or fundamental character of the work, and shall not be subject to protection as a derivative work under this title, except with the express consent of the copyright owner. This essentially defines the limit that you seek. Wierd Al compositions are so-o-o over the limits set for a compulsory license, but arguably (according to some), he might be able to avail himself of a fair use defense, because parody and commentary are the primary reasons for the fair use exception in the US. A &quot;cover&quot; is typically not fair use, in that it has a palpable effect on market and it is not &quot;transformative.
