Using images downloaded from Freepik, pixabay etc Can I legally use static vector images downloaded from freepik or pixabay to create my own animations and then sell them? Their license terms are a bit confusing for me. They say that I can use those assets in personal and commercial projects as long as I include attribution. But at the same time they disallow selling any &quot;derived work&quot;. Do my animations count as derived work? What if I buy a pro account on these services, which frees me from including any attribution. Can I then create and sell such animations?
License to use does not mean license to create derivative works These are different rights under copyright. If you want to make a derivative work, which your animations are, you must have a license to do so.
The creator of the software doesn't provide any warranty. If you feel confident in the quality of the software, nothing stops you from providing a warranty. If the software doesn't meet your guarantees, you will have to pay out because you provided the warranty, depending on the terms. Not the creator of the software because they explicitly didn't provide any warranty. If that's what you want to do, go ahead. I wouldn't. You don't have to republish under the BSD license, which you wouldn't. You must attach the license terms, which clarifies the role of the original creators, and that they don't give a warranty. Doing this allows you to copy the software. It doesn't mean you can't provide a warranty.
If you are using just the names, there is no issue - you can't copyright a fact. If you are using actual images (you appear to say you are not, but you also asked "Am I allowed to include images of Google Maps) - then the answer is still yes within your usage case - provided you attribute them to Google. If you look at this link it specifies that you are OK to use this in Reports and Presntations, Books which are not guidebooks and which have less then 5000 copies and presentations. If you are using them online, you need to use the imbedded versions (ie you can't just screenshot them - you need to link to them). If you are still unsure, you can contact streetview-academic@google.com to request specific permission.
The general idea of such an app is not subject to copyright protection. Ideas never are protected by copyright. So creating an app based on the functionality of a fictional app would not be a copyright violation. The logo might, if it is original enough, be protected by copyright. Any or all of the "name, the logo and the color scheme" might well be subject to trademark protection. (Names and other short phrases are not protected by copyright.) You would be wise not to use these identifying elements of the show, but instead create ones sufficiently different that no reasonable person would be confused into thinking that your app had been used on the show, or was sponsored, endorse, or approved by the show or its creators. An explicit disclaimer saying that you are in no way associated with the show or its creators, and your app is not approved by or endorsed by them would also be wise. Otherwise you might be accused of trying to pass off your work as affiliated with they show, or to trade on the show's reputation and fame. Whether you make your app an open source work is not in any way relevant to copyright or trademark claims. Whether you charge for your app is of only limited relevance to a copyright claim. Whether you sell or market your app, or use it to advertise some other product or service is relevant to a trademark claim, as trademarks are only protected against their use "in trade" which generally means commercially. However, non-commercial use of a trademark may constitute "dilution" of the mark, which may give rise to a cause of action against the person using it.
There are basically two kinds of things one could do. One could assign or transfer intellectual property rights and contracts related to the app to the entity, or one could license the intellectual property rights to the entity. Generally speaking, in a related party transaction, everything should be in a signed writing, and a notice of the transfer of an intellectual property right that has been registered or filed with a government agency should be provided to the government agency in question. Since there are potentially copyright, patent, trademark, publicity, and contractual rights that might be associated with the app, each aspect which exists should be transferred or licensed, as the case may be. While the forms to do this aren't particular long, the concepts involved and correct terminology are subtle, so this would not be a wise undertaking to attempt on a do it yourself basis.
This answer to a related question sums up the relevant concepts regarding work for hire. Since, according to your description of your relationship to A, you are not an employee (Commun. for Non-Violence (CCNV) v. Reid 490 U.S. 730), and you do not a written agreement, under US law, this would not be a work for hire: thus you hold copyright to something. I presume Company A gave you the source code and you are rewriting it to fit some technical requirement, so you have been given permission by the copyright holder to create a derivative work. You do not gain copyright to the original code: you only hold copyright to what you wrote. You would therefore need the permission of the copyright holder (of the original program) to sell copies of the modified program (currently A, company B in the future once the transfer is complete). There isn't a special "signing-over" ceremony for permission to copy, but the situation you describe is very messy. Even without a written agreement, you do understand that they intend to make multiple copies of the resulting program which includes your contribution, and you have received something of value in exchange for your contribution. So, one would argue, you have at least given permission to copy your stuff, even without a piece of signed paper -- in hiring you, you have given them an implied license to use what they paid you to create. The unclarity would be in whether you transferred your property rights, or simply licensed them to use it. Hence the recommendation to get an IP attorney.
From the perspective of US law: Scenario 1: Removing the watermark is perfectly legal, obviously. You own the copyright. Scenario 2: Abandonware is not really a thing in the US when it comes to copyright (and the Wikipedia article you linked says this.) Even if the company went out of business, the copyright almost certainly went to somebody - the former owners, the creditors, etc. As far as the Internet Archive goes, they are taking advantage of an exemption in the DMCA's anti-circumvention provisions, along with the copyright exemption found in 17 USC § 108. But both of these exemptions require you to be a "library or archive" to take advantage of them, and you are not a library or archive, so you cannot take advantage of either. As a practical matter, if the software is really abandoned it's unlikely that anyone will actually come after you for infringement, but that's not quite the same as it being legal - you could be on the hook for up to $150,000 in statutory damages per work infringed, if the owner does sue you. You could attempt to claim fair use, of course. If the image is abandoned you might get a favorable result on factor 4 of the fair use test (the effect on the market for the original) since there's no market if nobody can find the owner. But it would depend on the other factors; that alone wouldn't get you fair use. Scenario 3: I'm not sure where you get the idea that downloading a copyrighted image to your desktop is somehow protected. It isn't automatically legal to save a copy of something just because it's on the Internet. And the existence of a watermark may indicate that someone wanted to prevent the file from being copied. The website containing the image will likely have terms of use, which may indicate whether or not you're allowed to make a copy. For example, Stack Exchange's TOS says in part: Subscriber may download or copy the Content, and other items displayed on the Network for download, for personal use, provided that Subscriber maintains all copyright and other notices contained in such Content.
The film you want to base your game on is probably covered by copyright and likely trademarks. For purposes of the question I'll assume it's not in the public domain (if the film was made before 1926 for example). If you used the film to create your game, it would be a derivative work. Derivative works require the consent of the copyright owner. Distributing it without their permission would leave you open to lawsuits for copyright infringement, unjust enrichment, and possibly others. Fair use/fair dealing likely doesn't apply here. This isn't criticism, parody, or a transformative use. You may be able to get away with this by flying under the radar if you don't distribute it for profit or on any large scale. Some studios are more litigious than others and some accept that leaving fan works alone is better than the bad publicity that comes with shutting them down. However, this is entirely reliant on the goodwill of the studio. The legal way to do this is to get in touch with the copyright holder and ask permission. This may be in return for something else- usually money, royalties, and/or some creative control over your work. This may not be feasible though as a large company may simply ignore such requests from random people. Note that a lack of a response in this case is not permission.
