Does the WTFPL legally disclaim warranties? Say I make software and release it under the WTFPL. Then, someone uses it and it causes their computer to catch fire. I did not design my program to catch their computer on fire, and in fact it might be too simple to do so. Still, they bring me to court. Does using the WTFPL (or otherwise placing the product in the public domain) offer any protection? I ask this especially because it seems to often be used as a minimal license where it's not legal to release the product in the public domain, effectively placing it there. My biggest reasoning is imagining pencils. The design of a pencil (graphite embedded in wood with rubber on top) is in the public domain.[citation needed] If my arm swings into the pointed tip of a pencil, I don't sue the person (or family of that person) who invented the pencil. If anything, I sue the person who sharpened it, who placed it there, or who manufactured that particular pencil.
Short answer? No, the WTFPL offers no protection. A software license is a contract between the software vendor and the end user defining the terms and conditions under which the end user is permitted to use the software. Often, traditional software licenses contain terms that limit the vendor's liability. For example: "End User accepts the risk that this software will initiate computational conflagrations." It may also limit the end user's right to sue, by requiring binding arbitration, or by requiring them to sue in a particular court in a particular state. Whether and to what extent these clauses are enforceable is moot here, because the WTFPL doesn't contain them. Think of it this way. If you sign a contract with me to buy my house, and then you set fire to my car, you can't wave the house contract at me and say, "This is a legally binding contract, and it doesn't say I can't set fire to your car!" It doen't say that you can, either, and so it's not relevant to the lawsuit I'm going to bring against you for the damage to my car. Contracts are only relevant to a lawsuit if they contain a clause relevant to the subject matter of the lawsuit. The WTFPL contains no clauses in which the end user agrees to do or not to do anything, and therefore cannot be a defense against him or her doing, or not doing, anything at all.
If it's patented then it doesn't matter that you independently came up with it. Most software is not patented, though. Most developers do not even think about patents when writing code. In theory you could spend your time keeping up to date on software patents so that you avoid infringing. But this probably only makes sense for specialists who would want to read the latest patents in their field anyway. All software is protected by literary copyright, though. In this case they will try to prove that you did not independently created it, and did copy it. Whelan v. Jaslow in 1986 ruled that structure, sequence and organization of a computer program were protected by copyright. So you could be liable even if you did not just copy and paste sections of code. But even if you're worried the court would get things wrong and think you copied a program when you never even saw it in the first place, there is really nothing you can do about it.
Distribution on YouTube implicates, at least, US copyright law. Shropshire v. Canning 809 F.Supp.2d 1139 (N.D. Cal. 2011), Subafilms v. MGM 24 F.3d 1088 (9th Cir. 1994) Are you infringing? Is the original work eligible for copyright? &quot;It is undisputed that computer programs— defined in the Copyright Act as a set of statements or instructions to be used directly or indirectly in a computer in order to bring about a certain result, can be subject to copyright protection as literary works.&quot; 17 USC 102, Oracle Am., Inc. v. Google, Inc., 750 F.3d 1339 (Fed. Cir. 2014) (internal citations omitted). Are you making a copy or displaying the work publicly? (17 USC 106) You concede that you are doing this in the hypothetical, so we can skip this step. Do you have permission to do this? Some work is licensed to allow your proposed use. If you have permission, then this entire answer is moot. Are you taking what amounts to a substantial taking of the original? Presumably, you will not need to show the entire source file to present the naming conventions and techniques that other developers have used. But, what you do show will be an exact reproduction of the original. In the case of computer programs, all US districts use the abstraction-filtration-comparison test. Computer Associates International, Inc. v. Altai, Inc., 982 F.2d 693 (2d Cir. 1992). The abstraction stage of this test is irrelevant in this hypothetical because the reproduction is exact. Filtration excludes any uncopyrightable elements of the original from consideration (due to scènes à faire, merger, lack of originality). The comparison stage compares what remains after the filtration stage, to determine if the new work takes substantially from the original. Fair use defense If your use is found to be infringing based on the above analysis, the affirmative defense of fair use is available. I can't tell you whether a fair use defense would be applicable or successful in your particular case. However, you can search the US Copyright Office's Fair Use Index for many examples successful fair use defenses when a literary work was reproduced in part or whole for educational purposes. There are also other affirmative defenses available (implied license, for example), or defenses that directly attack the elements of copyright infringement. Some confusion exists regarding &quot;idea/expression merger&quot; as a defense after a prima facie case of copyright infringement has been made. This isn't completely correct. Where idea/expression merger enters the analysis differs from circuit to circuit. In the 6th circuit, merger enters in the copyrightability analysis (paragraph 1. above). But, the 2nd and 9th circuits treat merger as part of the infringement analysis (paragraph 4. above) and in the 9th circuit, merger is an affirmative defense. Ets-Hokin v. Skyy Spirits, Inc., 225 F.3d 1068 (9th Cir. 2000) The idea/expression merger doctrine is not implicated just because &quot;the idea one that is expressing is 'this is the code they used.'&quot; When you need to cite/show the original work for purposes of &quot;criticism, comment, news reporting, teaching&quot;, that is a direct implication of fair use. Using using this justification triggers the full four-factor fair use analysis. (17 USC 107). You don't get to reproduce a work just because you want to say &quot;this is the work they created.&quot;
The DMCA prohibits circumvention of technological measures that effectively control access to a copyrighted work. So you can't legally "crack" the software, period -- even if you own a disc containing the software and have a valid license to use it, a license to use the work is not authorization to circumvent access controls. So if the disc is copy-protected, by my understanding of the DMCA, you're kinda screwed. (The company might be willing to provide you a replacement copy, even if only to maintain the illusion that the software is "licensed, not sold". But you can't make one yourself.) Likewise, if you have a copy of the disc but have lost the license key, you're screwed. Even if you could prove beyond any doubt that you are the licensee, there's not any law i'm aware of that would compel the copyright owner to provide you another license key. And courts have held that distribution of license keys without authorization is a violation of the DMCA. So whoever might provide you another key, if they're not the copyright holder, has broken the law. If you managed to copy the disc from a friend (without circumventing any kind of copy protection), and had your own license key, you might be in a better position. Many EULAs allow you to make a backup copy. Even if they didn't, copyright law does, so there's a possible case for fair use.
Probably Not The creator or owner of a piece of software does not in general have any copyright over the output when others run the software, unless that output is itself a derivative work of input supplied by the copyright owner, or forming part of the software. In this case the translation is a derivative work of the 19th century original, but that is assumed to be in the public domain. SAo google has no copyright on the resulting translation. But copyright protection is only available for &quot;original works of authorship&quot;. (See 17 USC 102 in the US, and similar laws elsewhere.) A machine-produced translation is not an original work, and it is surely not then work of the author of the overall book. However, the author would still have a copyright on the book as a whole. The legal situation is no different than if the author had simply quoted a 19th century work. One may incorporate public domain works into a later work, and that later work is still protected by copyright, provided that there is enough original contentr to make the work as a whole &quot;an original work of authorship&quot;. Others may use the PD [arts, or the original from which they are taken, but not the rest of the work (beyond what fair use would allow in any case). For example, I have made a number of posts here on LAW.SE. In several,of those I quoted sections from one of the numbers of The Federalist. That 19th century work is in the public domain. Anyone else may re-quote the passages I quoted from it. But that gives them no rights to use the rest of my work, except as the CC-BY-SA license or fair use permits. So the author would retain copyright on the book as a whole. But soemoen who merely quotes or uses the translated 19th century article but none of the original parts of the book would not be infringing that copyright. I say probably in the header, because I do not have any actual case-law to cite here. It is possible that some court has rules otherwise on the subject of the copyright on the output of a software tool, but I strongly doubt it.
Please Note: This was written before the title change of this question and may no longer be applicable According to the Harvard website: In Feist Publications, Inc. v. Rural Telephone Service Co. 499 US 340 (1991) the United States Supreme Court held that copyright does not extend to a mere compilation of facts. In this case, it was a telephone directory much the same as the one in ProCD v. Zeidenberg 86 F.3d 1447 (7th Cir. 1996). Furthermore, the Court also ruled that something more than simple "sweat of the brow" labor was required before copyright protection would ensue, with some modicum of authorial originality necessary. Accordingly, it was held in Feist that copyright did not extend to a telephone directory, no matter how laborious a task its compilation was. The decision in ProCD v. Zeidenberg 86 F. 3d 1447 (7th Cir. 1996) is highly significant, therefore, in that it permits copyright or quasi-copyright protection to be extended to non-copyrightable material through the use of contract. One would have to consider each meta tag independently. For example, the "description" tag could by copyrightable since it is written for more than just the 'facts', such as a subtle advert for the site that is more than an objective description. However the 'og:type' would not be copyrightable since it would just be considered a fact. Now, if you are using it on another website and sourcing it properly, you could probably use it under "Fair Use" Uses That Are Generally Fair Uses Subject to some general limitations discussed later in this article, the following types of uses are usually deemed fair uses: Criticism and comment -- for example, quoting or excerpting a work in a review or criticism for purposes of illustration or comment. News reporting -- for example, summarizing an address or article, with brief quotations, in a news report. Research and scholarship -- for example, quoting a short passage in a scholarly, scientific, or technical work for illustration or clarification of the author's observations. Nonprofit educational uses -- for example, photocopying of limited portions of written works by teachers for classroom use. Parody -- that is, a work that ridicules another, usually well-known, work by imitating it in a comic way. A copyright would exist on the image. One would have to know what license currently applies to the image to know for sure, however, the "Fair Use" to copyright would still apply. With Fair Use, the entity type that uses the image is important. There is much more leniency when a non-profit uses copyrighted information than when the information is used in commercial activity. (With, of course, more exceptions.)
united-states You are protected by copyright as a matter of law, even if you don't post a copyright notice, although you have slightly more procedural rights if you do post a copyright notice and there would need to be a filing with the copyright registrar (a division of the Library of Congress) before you brought suit. You can't really get any other intellectual property protections for it except possibly a trademark if you have a distinctive mark or name or logo for the app.
When the question is "Can I be sued for..." there can't ever be a really useful answer, because anyone can be sued for just about anything. The suit may be tossed as pointless early in the process, but it can be filed. That said, could there be a valid ground of suit against a developer for creating a scraper? Possibly. Scraping a site could be against the site's TOS. It could be largely a way of committing copyright infringement. It could be unlawful in some other way. For most sites, scraping is not unlawful. Google does it all the time. If there is no legitimate use for the scraper, or very nearly none, so that any user is likely to be acting maliciously and unlawfully, and if the developer knows this, or any reasonable developer should know this, then the developer could possibly be found liable for the illegitimate actions of those who use the scarper. If there is a legit use for the scraper, or the developer would plausibly think that there is, then such development is not illegal, and a successful suit against the developer is unlikely.
