What happens if open hardware infringes existing patent? For example, maker community builds a machine implying/related to technologies/concepts under patent, and licenses these under GPL. What are the consequences? Example: electronic beam welding patent by NEC vs. MetalicaRap community effort.
I've answered this in the context of US patent law, but similar principles apply elsewhere in the world. As stated in 35 USC 271, "whoever without authority makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent therefor, infringes the patent". Thus, a patent provides the patent owner with the right to exclude others from performing these actions, and the right to sue anyone who does perform these actions (both to stop them from infringing the patent, and to collect monetary damages for their infringement). Creating an infringing product and then licensing it under the GPL (or any other scheme) does not change the fact that it infringes a patent. 35 USC 271 also states that "Whoever actively induces infringement of a patent shall be liable as an infringer". This means that, even if the creator of the infringing product does not perform any infringing acts in the US, the act of offering it for free use could be construed as induced infringement of the patent, and they could still be sued for that infringement.
This supposes that the patentable concept can’t be learned form the operation of the whole program and hiding the invention while making use of the invention in public is not a disclosure. However, in the US there is a famous case In re Blaisdell, 242 F.2d 779, 783, 113 USPQ 289, 292 (CCPA 1957); Hall v. Macneale, 107 U.S. 90, 96-97 (1882); Ex parte Kuklo, 25 USPQ2d 1387, 1390 (Bd. Pat. App. &amp; Inter. 1992) that concluded a public demonstration that didn’t expose the inner workings did start the clock on a bar to patentability. See previous question https://patents.stackexchange.com/questions/20886/would-the-demonstration-of-an-invention-be-considered-public-disclosure The answer (from me) has the caveat that this is a pre-AIA case and courts might come to a different answer under that current law. The U.S. has viewed public use, especially commercial public use, as disqualifying (after a grace period) but the rest of the world puts its emphasis on actual disclosure of the inventive concept so this result might be different elsewhere. One thought experiment would be to analogize with an article in a widely available journal with the words Don’t read the article that starts on page 19 on the cover. From a disclosure point of view I do not think that is different from it being possible, but illegal, to read.
You will want to speak with a patent attorney, not a labor attorney. Some of the facts you are presenting are entirely wrong. Patents have inventors, copyrights have authors. Inventorship has strict rules. Inventorship cannot be denied without consequence in almost any jurisdiction, but you'll need to get local legal advice. In the US, "A patent is invalid unless it lists the first and true inventor or inventors of the claimed invention." (See Stark v. Advanced Magnetics, 119 F.3d 1551, 1553, 1556 (Fed. Cir. 1997); 35 U.S.C. § 102(f) (“A person shall be entitled to a patent unless . . . he did not himself invent the subject matter sought to be patented). See also 35 U.S.C. §§ 111, 115-16, 256.) Assignment--the "ownership" of the patent--is different. It's very common to have you sign an agreement as a condition of your employment that you grant full assignment to your company for any patentable material created under their employ. If you did not, it is possible that the company would need to give you consideration for the right to assignment, e.g., they would have to pay you something to own the patent. If you are no longer there, that "something" can be substantial, because the patent is invalid without it, and they have little leverage over you. Bring all written records, emails, etc. to a licensed attorney who specializes in patent litigation.
Yes. This is a frequently asked question on the foundation's homepage, and answered without ambiguity (source): Can I use a Raspberry Pi in a commercial product? This is a very common question, and the answer is yes! Once you have bought a Raspberry Pi, it's yours to do with as you wish. You would be in good company too, as in fact the Raspberry Pi is regularly used and sold for commercial applications third parties. Note that this the default consequence of a contract of sale in all jurisdiction I know of (but I am not a lawyer): The seller does not retain property rights in the particular item, and by the mere selling of the item implies there are no other rights that might prevent the buyer from using it as they wish. Apart from the particular computer now in your property, there are other legal requirements: &quot;Copyleft&quot; softweare: Large parts of the Raspbian software are licensed under &quot;copyleft&quot; licenses (importantly, versions of the General Public License, GPL). These licenses are meant to provide your customers with the means of reproduciing and building upon the &quot;copylefted&quot; software. You will need to provide your customers with the source code to those software items, the tools and documentation needed for building, and a written notice. Your own programs need not be licensed under a &quot;copyleft&quot; license, provided that you don't build on (distribute &quot;derative works&quot; of) &quot;copyleft&quot; software. The open source licenses involved are not meant to exclude commercial use, and there are helpful compliance guides available ( a, b ). Non-free software: Make sure to not include non-free software, like Mathematica or Oracle Java, which are not licensed for commercial redistribution. Trademarks: Your use of the words &quot;Raspberry PI&quot; or the raspberry logo is subject to restrictions, as is usual with trademarks. Speaking of the logos: You can request permission to use their &quot;powered by Raspberry Pi&quot; logo. Market regulations: You need to abide by regulations, for example safety and electromagnetic interference. Repackaging the Pi might mean you'll need to test and recertify your product, I'm not an expert. Video codecs: Some Raspberry Pis (up to 3) include specialised video decoding hardware. If you want to use it with the MPEG2 codec, you'll have to buy an activation key for small one-time fee per device - £2.40 for MPEG2, £1.20 for VC-1; other codecs are already activated. I don't think you'll need a license even for commercial, for-sale devices, but I am not your lawyer. Just to be clear, nothing prevents your buyers from cloning your software. (This is not a consequence of you providing the Raspbian source code - they can just clone the contents of your SD card.) While you can retain copyright in your own code, you'll probably have no effective means of detecting infringement. However, the physical design of the rest of your device will not be affected. Your business model needs to account for this fact.
Software qua property is protected by copyright *perhaps patent, in some jurisdiction). The general rule is that whoever creates the thing (book, song, software) has the exclusive right to the thing. If an employee of Company 1 writes software for Company 2, that employee might (rarely) hold the copyright, but typically that scenario would involve a "work for hire", where the employee is hired by Company 1 to do such tasks as part of his duties with Company 1 (which might then be given to Company 2). This would then be a work for hire, and the copyright is held by Company 1. If the actual author was an independent contractor, he would hold the copyright – see Community for Creative Non-Violence v. Reed for analysis of the subtle nuances in making that determination. The concept "work for hire" which crucially involves the "employee" relationship would not be applicable to Company 2 paying Company 1 for a product, and as long as the actual author is an employee of C1, C1 has not created a "work for hire" in the legal sense. Without some explicit disposition of copyright, Company 2 is in a sketchy position. Since C1 holds copyright, they must grant a license to C2 so that C2 can legally use it; or, C1 must transfer copyright to C2. This does not happen automatically, and (if C1 does not want to remedy the situation after the fact) C2 would need to take C1 to court to force a resolution to the situation. At that point, the issue would be what C1 implicitly promised, even though they didn't put it in writing. It is likely that the initial exchange was along the lines "Can you make us a program that will do X?", and the answer was "Sure, that will cost Y", and then "Okay, go ahead, looking forward to the product". The courts would not simply say "Well, you didn't explicitly require a license, so you don't get to actually use the software that you paid for". However, it's a somewhat open question whether the court would order a license (of what nature?) or a transfer of copyright. The disposition would depend heavily on the facts of the case (what was said, what C1 actually did, what kind of business they are, what did creating the work involve...).
Disclaimer: I'm from the US and don't claim to know German or Turkish law. So let me discuss some general principles here, but details may well be different in Germany and Turkey. You're mixing together three very different things: trademark, copyright, and patent. Copyright protects the expression of an idea, in this case, the exact computer code, images, etc. If you didn't copy his code, the chance that you would coincidentally write identical code is remote. The fact that you both have a line of code that says x=x+1 wouldn't give him any grounds for a lawsuit. He'd have to show substantial portions of the code were identical. If you didn't deliberately copy his code, this isn't going to happen. Barring some extraordinary and unbelievable coincidence, you can't violate copyright accidentally. Trademark protects names and symbols used to identify a company or a product. If you decided to call your software company "Microsoft", then that other Microsoft could sue you for trademark infringement. Likewise if you copied somebody else's logo or other distinctive graphics. This is very different from copyright. It is quite possible to violate someone's trademark accidentally. Especially if he gave his company or product a rather generic name. Like if someone called his product, say, "Password Manager", someone else might make a product with the same name without ever having heard of the original. Ditto if he has some simple logo or other graphics. If you did accidentally duplicate a name or graphic elements, well, in the US a court would likely order you to change your name or graphics and that would be the end of it, unless you refused, in which case you'd end up in court. US Courts have ruled that very generic names have limited trademark protection. An example I saw recently was "Main Street Auto Repair". A court said that the owner of that name could prevent someone else from opening a shop in the same town with the same name, but he couldn't sue someone in another town who happened to use the same name. This is why, by the way, companies often use made-up words for their product names. In your case, this should be a trivial issue. If he is claiming trademark to the look of the main menu screen, just change the colors or move some buttons around. If it actually went to court, you should be able to argue that the similarity was accidental and when you were informed you promptly changed it, and that should be the end of it. Depending, I guess, on how hard-nosed the judge is, etc. Patents are different still. A patent gives the owner the exclusive right to use an invention or process for a specified period of time. It doesn't matter if you invented the same thing entirely independently. Whoever filed the patent first has exclusive rights. There have been cases where an inventor lost out to someone with a similar invention because he submitted his patent application one day later. If this other person has patents that you are infringing, you are pretty much out of luck.
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.
The reason why I could not find the patent is that there are several different kinds of patents. Mechanical patents, for example, are &quot;utility&quot; patents. The cut glass pattern referenced in the question is not a utility patent, it is a design patent. Each patent type has its own numbering system. To search for a design patent, typically a &quot;D&quot; is inserted before the patent number, like &quot;D63795&quot;. This results in the correct patent being discovered:
