May I show a printed circuit board of a device on the internet? Do I need a permission to show pictures of a printed circuit board of a device (consumer electronics) on my personal blog? I would like to show how certain modifications to the product can be made. I took some pictures during the process. Does sharing these pictures infringe any IP rights?
Yes, you may The layout of the board and its appearance are not protected by copyright, because they are not expressions or any other type of copyrightable content. Even if they were (say if some protested art was displayed on the board) you are displaying this for instructional purposes, and not harming any market for the board, so fair use is likely to apply (in the U.S.). The device could be protected by patent, but you are not copying or imitating the board, nor showing anyone how to do so, so that would not apply. You are not selling or advertising the board, nor knock-offs of it, so trademark protection would not apply, even if a protected trademark is visible on th board. Just in case, be sure to make clear that your video is not authorized or endorsed by the maker of the board.
Yes, that’s allowed. Under the Stack Exchange terms of service, content you upload is licensed to Stack Exchange Inc. on a non-exclusive basis under CC-BY-SA 4.0. The terms of service do not give Stack Exchange the copyright to your contributions, and a non-exclusive license means you are not promising Stack Exchange that “only Stack Exchange will be allowed to use this content.” That means you can continue to do whatever you want with your own content and do not need to mention Stack Exchange at all. The only restriction is that you can’t stop Stack Exchange from continuing to use your Stack Exchange content under CC-BY-SA 4.0, and since it’s a Creative Commons license you also can’t stop anyone else from using your Stack Exchange content under that license.
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 board rules. Companies usually go to great lengths to be sure the company owns the IP developed within and for the company. But the company is governed by its board of directors and that board can decide to take the company in a new direction where some IP that the company owns would no longer be a key asset for ongoing business. Selling that IP to another organization might, then, be logical. Boards are elected by, and represent, the owners of the company.
You can’t use pictures You can’t use any of these, nor can you make your own art that is derived from these. That’s copyright infringement and there is no fair use defence because you are specifically trying to do something Nintendo already does. You can reproduce that stats of the Pokémon because stats are facts (even if they are facts about fictional things) and facts are not protected by copyright.
The whole purpose of a patent is that the contents of the patent becomes public knowledge, in exchange for a time limited monopoly. Therefore you are allowed to do anything, since you are not just allowed but expected to examine the patent in order to improve on it, except that you need a license to sell or give away products implementing the patent as long as it is valid. The only thing to be careful about is that by publishing source code, you might be enticing others to infringe on the patent, so I'd recommend not to do that without advice of a lawyer. PS. With software, the interpretation of "making" software in patent law may be a bit surprising. There was a major case between Microsoft and AT&amp;T about that. The software developer isn't "making" the software. The build engineer putting everything together isn't "making" the software. The CD manufacturer making a million copies isn't "making" the software. The person installing it on their computer is the one who makes it.
IANAL, and as @GeorgeBailey suggests, you should ask one. That said, some aspects of your question are directly addressable with what we know. Does US law states anything about this? Yes. Federally this falls under the Wiretap Act, 18 U.S.C. §2511. Workplace monitoring generally falls under either the "System Administrator Exception" or under Consent. In general, continuing past a banner constitutes consent. Does company policy enforcement with such a warning over ride the right to not be subject to surveillance? In general, yes. You don't need to use the companies network if you don't want to consent - and they don't need to hire you if you don't want to use their network. But it's their network, and their rules apply. There are some nuances, and courts have found that the wording of the notice has made a difference in some cases, but overall, if the systems are properly posted with banners, then the employer may capture communications. See the "Bannering and Consent" section of this article from cybertelecom.org, e.g.: Even if no clicking is required, a user who sees the banner before logging on to the network has received notice of the monitoring. By using the network in light of the notice, the user impliedly consents to monitoring pursuant to 18 U.S.C. § 2511(2)(c)-(d). Note that stored data is covered by different laws than communications. It's a nuance. Is it ethical to sniff all the data without giving any other warning than the logon banner? "Ethical" is a very different question than "Legal", and largely more subjective. Most employers require signed consent for monitoring as a condition of employment, and use banners thereafter. That is ethical by my definition, in that it meets or exceeds the requirements of the law, and does not mislead or use subterfuge. The tone of your question suggests you find it distasteful, and therefore probably it violates your personal code of ethics.
Copyright never protects ideas or processes, it only protects expression: words, images, and sounds, some of which may describe ideas. But when a work is nothing more than a translation of an idea into words, with no independent originality -- when almost anyone would use more or less the same way to describe the idea, then the work will not be protected by copyright at all, as it is not considered an "original work". Computer code that implements an algorithm often falls under this rule. It is my belief that the code shown in the linked SE thread would fall under this rule, and would not be protected by copyright at all. If this is correct, then anyone may share such a program with no copyright concern.
