Can you be sued for money if your product is released for free? Say I create a product that I release for free and take no profit in any way. If this product somehow violates the copyrights or trademarks of another company, is there risk of needing to pay for damages to that company?
Yes. Money damages can be awarded in this circumstance and would likely be awarded if the infringement was found to have occurred and not to have been fair use. Even in the absence of proof that any profits are made, there are statutory damages that can be awarded on a per offense basis for copyright violations, and trademark cases in addition to having statutory violations can measure damages by harm to the trademark owner and not just unjust enrichment to the infringer.
Why do you think Oracle have not been protecting their trade mark? Using a trade mark to describe the product (“Written in JavaScript”, “Seeking JavaScript developer”) is not an infringement and the trade mark owner is under no obligation to, indeed, cannot stop this. Where they are required to defend their trade mark is when it is being used in such a way that there is the risk of confusion that the goods or services could be confused with the trade mark owner’s goods or services. Further, they are not required to defend all breaches, only enough to show that they are actively doing so. Also it is not important that the trade mark be associated with the trade mark’s owner. Do you know who owns the trade mark “Ben &amp; Jerry’s”?
The band's logo can be protected by both copyright and trademark. The band's name is probably only protected as a trademark. Trademark would not apply to your personal use, because to infringe a trademark, you need to "use" the mark, and "use" in trademark law generally means selling an item that has the mark on it. As far as trademark law is concerned, no sale means no infringement. Copyright protects the exclusive right of the owner to copy a "work" (it's much more complex than that, but we don't need to get into the details here). Copyright probably applies because you would "copy" the logo, which under copyright law is something only the copyright owner can do (absent authorization from the copyright owner). You would therefore theoretically be infringing copyright by copying the bands logo on a shirt or something you want to wear yourself. That said, while I agree with the first answer that fair use may apply in theory, there would never ever be such a complex discussion about fair use in this case... because in fact there's absolutely no chance an individual would get fined or sued for having copied a band's logo and name on something he/she wants to wear his/herself. Getting sued by the band The band will not notice. If you're lucky enough to meet the band (or somebody close to the band) in person while you are wearing your garment, they would either not notice or not care. At worst, they'll ask you where you bought it in case they suspect you bought it from someone who illegally sells fake merch. Even then, all of this seems very unlikely. If you are extremely unlikely and the band notices it and sues you (and finds a lawyer to take a case like that to court), my inclination is to think the judge would be extremely mad with the band (and its lawyer) for losing the court's time with such a trivial matter. No judge would allow lawyers to waste the court's time pleading such a complex thing as fair use in a case like that. Getting fined The police would not notice either, because the only time the police cares about copyright is when somebody makes a complaint (nobody would make a complaint about you), except when they seize containers full of copyright infringing stuff (that is destined to be illegally sold for profit) in a port or at a border somewhere. The only possible scenario where I could imagine that there would be legal consequences is if you wear a t-shirt with the bands logo in a YouTube video (or in a picture) where the only thing that you see basically is the bands logo on your t-shirt. Even this scenario is extremely far fetched, but let's say the video becomes popular and the band notices. Well, the likeliest scenario is that they would file a DMCA notice and get YouTube to take down the video, with very little chances that there would be more important consequences to you. Have fun!
Here's where you went wrong legally: Suppose I legally obtain some digital image created by somebody else (e.g., by downloading from a public website). That, right there, is copyright infringement- unless the copyright owner has granted permission or the image is public domain you cannot copy it - this breaches "the right to make reproductions". By posting it on the web (assuming that it isn't itself an infringing copy) they have given implied permission for you to look at it in a web browser but not to copy it into a presentation even if that presentation is never presented. If it is presented then that makes the infringement worse - it adds breaches of "the right to communicate to the public" and "the right to use the work as a basis for an audiovisual work". How is this different from the computer wallpaper? It isn't. If you are using the one of the defaults that shipped with the OS then the license gives you permission. If you are using someone else's copyright without permission then it's a breach. There are defenses to copyright infringement but these are quite nationally variable - search this or other sites for "fair dealing" and "fair use".
If you have a truly novel and non-obvious game idea, you could patent it, and that would cost many tens of thousands of dollars if not hundreds of thousands of dollars (U.S.) in legal fees, etc. and probably a couple of years of patent prosecution, if your idea has not already entered the public domain through public display or sale. Most ideas for games are either not novel, or would be obvious to a person skilled in designing games. But, if your idea is really and truly new, you could do it.
It would be copyright infringement. You had the copyright holders permission to make one copy of the song by downloading it. At that time, if you gave me a copy of that song, it could be argued that very, very little damage was caused because I just had downloaded that song myself with practically the same effect. Today, that argument is not valid anymore. So this is definitely copyright infringement. That's your question answered. I doubt that anyone would take action if you gave a copy to someone and it was found out. Making it available to the world for free download is another matter. That could easily get you into trouble; in the USA there could be a fine up to $150,000 without any proof of actual damages needed.
Making a profit does not make the act illegal: it is illegal without there being any profit. The act of copying without permission is what makes the act illegal. Profit might maybe enter into the matter if you are talking about the "fair use" defense, since certain kinds of works can be partially copied for certain purposes. You could quote a few lines from a novel in a review, for instance. The judgment of whether a given act of copying without permission is allowed under fair use is complex and involves a balancing act. Profit becomes relevant in that a non-profit use favors fair use and a for-profit use disfavors it. Wholesale copying of works of art as you describe is illegal (is infringement). However... "illegal" is a pretty broad concept. If you infringe on my intellectual property, you almost certainly will not suffer any consequences unless I sue you. Taking "illegal" to mean "in violation of the law", infringing copyright is illegal because it violates the law, but I have to make a federal case out of your infringement – I have to sue you. As it happens, it can also be a crime to infringe copyright, and in that case, the government and not the copyright holder pursues the matter. If a person knowingly infringes copyright, he might be prosecuted, thus the Megaupload case which in the US is realized in the indictment US v. Dotcom. Moreover, profit motive is a required element for criminal infringement. (Also note that you don't have to actually make a profit for the profit element to be present). You cannot sue a person unless they have harmed you, so if you know that Smith copied Jones' work you can't sue Smith for harming Jones. (This is what they call "standing"). You might sue Smith, but not for infringement itself. If they sold you an illegal infringing copy, then you could sue. Or, their infringement could diminish the value of your legal copy. This website gives a multi-nation overview of criminal copyright infringement laws.
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.
