Are published sports results copyrightable? In NBA vs. Motorola where Motorola did not infringe NBA's copyright by publishing scores of games. However, I am wondering if published scores are copyrightable. For instance, the result "Bulls 99-89 Lakers" itself may not be copyrightable (since it's a fact), but what if it is published on the NBA website? If I want to use the score that is published on the NBA website (without reaching an agreement with NBA), would I infringe NBA's copyright in that case?
The fact is not copyright: the method of presentation (font, colour, logos etc.) is.
Can he use another commercial product that is copyrighted, e.g. a map of a location (the map is a political map and has nothing to do with trees), for his tree research purposes, if such a map won't be part of the book he works on? Yes. Copyright protects particular expressions of ideas and knowledge, not the ideas and knowledge themselves. Using a map for research purposes when the map or a modified version of it does not appear in the final work does not make the final work a &quot;derivative work&quot; covered by copyright.
Copyright in musical works extends to the composition itself, not just to the sheet music (as you notice, there may not even be any sheet music). If the musical work is protected by copyright then publishing a transcription of that work would be a potential violation of the copyright, subject to exceptions such as fair-use and fair dealing. If the piece is in the public domain, then you can publish your transcription.
Yes and no. [note, the following is all written about US law. In other jurisdictions laws are, of course, different (though usually not drastically so.)] In the US there are (at least) three different bodies of law that might apply to code: copyright, patents, trade secrets. Copyright covers original expression. Anything you write is automatically, immediately protected under copyright. The copyright applies to the code itself, and anything "derived" from that code. It's up to the courts to decide exactly what "derived" means. One case that's long been viewed as a landmark in this area is Gates Rubber v. Bando Chemicals. The Court of Appeals for the tenth Circuit decision includes a section titled: "The Test for Determining Whether the Copyright of a Computer Program Has Been Infringed." Note that you can register a copyright, and that can be worthwhile, such as helping recover some damages you can't otherwise. Patents are quite different from copyrights. Where a copyright covers expression of an idea, a patent covers a specific invention. Rather than being awarded automatically, a patent has to be applied for, and awarded only after the patent office has determined that there's no relevant prior art to prevent it from being awarded. A patent, however, covers things like somebody else independently discovering/inventing what's covered by the patent. A trade secret could (at least theoretically) apply to some process or procedure embodied in the code. A trade secret mostly applies to a situation where (for example) you're trying to form an alliance with some other company, and in the process tell them things you don't tell the general public. If you've identified the fact that what you're telling them is a trade secret, and they then tell a competitor (or the general public, etc.) or more generally use that information in any way other than the originally intended purpose, it could constitute a trade secret violation. As a side-note: patents and copyright fall under federal law, so they're basically uniform nation-wide. Trade secrets mostly fall under state law, so the exact details vary by state. Absent a reason to believe otherwise, I'd guess your interest here is primarily in copyright infringement. The key here would be showing that one piece of code was derived from the other. That is, it specifically would not apply in a case where there were only a limited number of ways of doing something, so anybody who wanted to do that had to use one of those ways. Since this would not indicate actual derivation, it would not indicate copyright violation.
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.)
The "Crabs" game can be legal if it is seen as a form of parody. That is one of the forms of "fair use" that allows copying (within limits). This is to allow the use of limited amounts of copying for critical or "mocking" pieces, which are considered a form of free speech. Two other issues come into play under "fair use." The first is whether or not this is "commercial" (yes) or non-commercial (e.g educational) use. That is mildly negative for "Crabs" but by no means dispositive. The second is the likely market impact, whether the new use tends to compete with the old use in its "home" market, or whether it is likely to open a new market of a very different, perhaps "opposite" audience that might later buy the original as a "crossover." The "Crabs" game seems to address the "green" or at least "pro animal" (PETA) market. If the defendant can show that the "Cards" market addresses e..g., your "inner Nazi," making it "opposite," that would be ideal. It would be less convincing if "Cards" were addressing e.g. human rights, because that might be seen to overlap with the green market in terms of social conscience.
This kind of quotation, for commentary, criticism, or reference, is generally allowed without obtaining permission. In the US, this falls under fair use (see 17 USC 107. In the UK and most commonwealth countries, it falls under fair dealing. In other countries there are various exceptions to copyright that will probably cover this. Even answers that do not directly quote the rule books often use information from those rulebooks to write an answer. Facts and ideas are never protected by copyright, so this is not going to be an issue. See 17 USC 102(b), which provides: (b) In no case does copyright protection for an original work of authorship extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery, regardless of the form in which it is described, explained, illustrated, or embodied in such work. As a comment by user Trish reminds, game rules are facts and are not protected, although their exact wording may be.
Copyright law requires permission of the rights holder to e.g. post material. The terms of that permission could be very complicated, as seen in royalties contracts with publishers, but they can also be simple. If someone asks "can I post your video on my website" and you say "Sure, as long as you give me credit", then they can post the video on their site as long as that say something like "This video was made by Jake" or something like that. There is no exception to permission where permission is retroactively withdrawn just in case it turns out that one can make money off of the video. However: you gave That Guy permission, and that does not mean that the hundreds of Other Guys have permission. So you can pursue all of the Other Guys and demand that they take the video down, or require some payment to get your permission.
