Is taking screenshots and printing pages out considered fair use, in most cases? Making a copy of anything could be considered copyright infringement, but what if it is for personal use rather than for distribution? Suppose I print out or take a screenshot of a webpage or a lecture presentation or an eBook and store it somewhere? Would this be likely to be fair use? I would guess the answer is no in some cases (you cannot copy an entire eBook intended for temporary use), but yes in most cases, such as if I print out or download a page on a publicly accessible webpage for personal use.
It is not possible to say that this is generally fair use, although sometimes it would be. A copy for personal use is still a copyright right violation on its face, and fair use does not categorically exclude non-commercial or personal use of copyrighted works. It is a highly fact specific inquiry. The likelihood of anyone discovering that you have done so and deciding to sue over it is slight, but that doesn't mean that there isn't potential copyright infringement liability. Compare this to speeding. People do it all the time, and even driving one mile per hour above the speed limit is still a traffic violation. But it is rare for less serious violations to be ticketed.
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.
Your title and your question are totally different. If someone pirates a book, makes printed copies, and sells them for profit, that's the point where it switches from plain copyright infringement to being criminal copyright infringement. Which means jail instead of paying damages is possible. If you buy one of these printed copies, not knowing that they have been created illegally, and not being willfully ignorant that the printed copies were created illegal, then you didn't commit copyright infringement yourself. Since you are asking the question, it's obvious that you now know that there was copyright infringement, and buying any more copies would be encouraging copyright infringement with no excuses for you. You can be sued for damages. It is unlikely to happen since suing takes likely more effort than getting any damages from you is worth. The correct thing to do is ask the seller for your money back and destroy the copies. If they don't refund your money you can inform the copyright holder.
You automatically have a copyright in any copyritable things you create. So you own copyright over the pictures you sent him (as long as you created them)
No These are derivative works and making them is copyright breach. Doing this as a hobby or even for the entertainment of friends in private is likely fair use. Distribution or performance in public (monitored or not) is likely not fair use and you would need a licence. Here is a summary of the relevant law in australia.
Copyright Prominent at the bottom of the page is: © RealClearPolitics 2015 This is nice because it tells you who you have to approach for a licence. If it wasn't there the material would still be copyright you just wouldn't know who owned the copyright. Questions So: If I'm looking to build an app or write a book and I wish to use statistics, am I allowed to basically use their numbers as long as I cite where it is coming from? No, unless what you do constitutes fair use and I don't think it does. If I do make a profit from it, do I owe any royalties to the original scientists/surveyers? No, but you would owe whatever licence fee you negotiated with the copyright holder, ostensibly RealClearPolitics. Must I ask them for permission? Yes, unless you are OK with running the risk of being sued. Commentary I see books reference hundreds of studies all the time This is because they are generally protected by Academic Fair Use public polls should be open information to everyone The only public poll that I know of is an election and that information is available. What you are looking at is a private poll commissioned by and paid for by RealClearPolitics and it is their intellectual property; why should that "be open information to everyone"? commercial interests may be legally entangling Always
In Australia at least I am not sure that the usage you describe has ever been legal. The University of Melbourne Copyright Office sets out when you may copy a television program for personal use and fair dealing for research and study. In short for personal use, you may: use any format you like - if you can find a working VCR; go for it. Not lend or sell the material; it must be for your own private use. This means you must be there when it is displayed and it must be in a private place. For example, you can invite friends to your place or go to a friends place and watch it together. The thing you are copying must be legal - you must have bought the original, have a current pay TV subscription (at time of recording) or it must be a free-to-air broadcast.
It turns out that there is no difference between the ethical answer and the legal answer, in this case. The law recognizes the property right which a person has when they create a thing, such as a font, and that right is encoded in the law of copyright. The relevant US federal code is contained in Title 17, which you can read (essentially identical laws exist in virtually or perhaps actually all countries). The important thing to understand is that there is not a distinction between "privately" trespassing on a person's property and "publicly" trespassing on a person's property. The violation of the owner's property rights comes from taking the material without consent. There is a legally-recognized exception to the owner's rights, in the form of "fair use", which is widely misunderstood to mean "if it's not for profit, the property owner has no legal protection". Simply taking and using someone else's IP non-commercially is not "fair use".
