Is there a Legal Requirement for Computer Companies to Include an Operating System when Selling a PC? I asked a company if they could sell me a PC without an installed Operating System, as I plan to install my own. Their response was that "We have to legally include a OS with all of our systems. So we include Windows 10." It surprised me that this would be a legal issue rather than a company policy. The company is based in Utah. Is this an actual legal requirement by law? Why? Could it be to protect consumers? Would it protect the company from liability? Is it likely part of a contract they are in? Or is this a misunderstanding by customer service? I didn't find anything with a cursory web search. (I am a new poster, so any critiques of my question are welcome.)
No AFAIK there is no such legal requirement. Why this company told you there was I can’t speculate. But I will. There may be under contract with MicroSoft to put their OS on every box they sell - that would be a legal requirement. Or the just don’t sell boxes without this and they employee told you it was a legal obligation to get out of the conversation.
No They will list the price they are charging you. This will normally be greater than what they paid because that’s how business works. The amount they are allowed to charge is what you agreed in your contract with them (which may incorporate a price list) or, if the contract is silent, a reasonable amount. What is reasonable will be related to what the market in your geographical area charges. While this is indirectly related to the input cost of a given item, business can and do charge what the market allows.
united-states The license won't let you sell the .stl file. Probably you have created a derivative work, which means you can't sell it without a copyright license (and the CC-A-NC won't do). If it were licensed under CC-A you could sell it without problems (you'd have to give attribution, of course). You could also sell it under the CC-A-SA, but once you do you have no control over the result -- anyone you sold it to could give it to someone else under the terms of the license. This could work, though, if it were (say) a commission and you only expected to sell one copy. I don't know what the situation would be with the physical objects printed under any of these licenses.
Unless you have a legally valid IP right related to the specification that statement is meaningless. When a software license is granted it is based on the copyright of the code. The copyright of the spec. just stops people from copying the spec - it does not protect the information in it. You can restrict copying of the spec. under copyright, you can make up a name for the spec (like USB or Bluetooth) and get a trademark and only allow the trademark use in limited cases(doesn’t stop implementation of the spec), or get a patent that would be necessarily infringed if something complying with the spec was created and used, sold, made, etc. or you can keep it secret and only show it to people who contractually agreed with your terms.
Is it illegal to ask a company for money in exchange for information on a bug in their software/website? That in itself is legal. Indeed, the company would incur unjust enrichment if it coerced you to disclose your discovery for free. Only if you threatened the company to divulge to others your discovery unless the company pays you, it would be illegal and trigger charges such as extortion (likewise, legislations outlaw the unjustified delivery of programs or instructions for hacking a software/network/etc., although this goes beyond your actual question). Can the company take legal action against me? That seems doubtful, futile, and it could backfire (please note I have not done any research on legal precedents about this). Although the terms and conditions of the website or the End User License Agreement (EULA) of software might prohibit you to reverse engineer (RE)/decompile/etc. the application, anti-RE clauses are unenforceable and the remedies therefor are indeterminate because the sole act of conducting reverse engineering does not subject the company (or third parties) to any losses. The company's decision to take legal action for your discovery could backfire from two standpoints. First, it calls attention to the fact that the software at issue is defective and unsafe. And second, the bug is likely to be detected by someone else anyway, thereby potentially compromising customers' systems.
The website owner brings in an expert programmer who testifies that the user cannot have gotten to a certain part of the site (or download, etc.) without having clicked to accept the terms of service, and that this document they're holding is a true and correct copy of the terms of service as of that date. That's evidence in favor of the site, and an adverse party has to have stronger evidence in order to overcome it. If the person didn't save a copy of the terms themselves, they'll have a hard time on this. Then the other party's attorney tries to discredit the programmer by asking questions like "how do you know there are no bugs in the software which could have allowed somebody to reach this without agreeing to the terms of service" etc. Apparently, some sites don't require users to click indicating agreement. If the company has significantly changed the site, terms of service, etc. since the time the user registered, and doesn't keep any copies of old versions around, and admits this, they'll have a hard time enforcing an agreement (as they can't produce a copy of it). If the user kept a copy, the user might be able to present that. It's up to the finder of fact to decide what to believe and how much weight to give the various witnesses' testimony.
The title of your question suggests that a patent is involved, but it isn't clear from the rest of your question if that is really the case. Simply seeing a product on the internet does not mean that there are any patent rights attached to it. If a patent does exist, then that patent's protection is defined by its claims. In the US, if you make or use an object that includes all the elements of the claims of a granted patent, then you are infringing that patent. It does not matter whether you share the object or attempt to make money from it—simply making or using it is enough to qualify as infringement. That said, based on your intended use, the patent owner is highly unlikely to ever find out about your infringement. Further, even if they did, enforcing patent rights in court is incredibly expensive (typically involving multi-million dollar legal budgets), and they wouldn't stand to recover much from you, so it is even less likely that they would sue you for the infringement.
Similar to this question and this one, the Uniform Commercial Code requires that exclusion of warranty be conspicuous. While it does not specify the manner in which text should be made conspicuous, putting it in all caps certainly has that effect if the surrounding text is in sentence case. The meaning is that all products come with implied warranties of merchantability (it is good enough to be sold to you) and fitness for purpose (it will do what it's meant to, and what you've been told it will do). This text excludes this product from those warranties (that is, those warranties do not apply). It also disclaims liability for claims and damages, which means that if this software causes you harm or damage, you can't file a suit to recover any loss. Whether this is enforceable would be decided by a court.
