Applying for a patent in one country using a patented invention beloning to some else from another country Let's assume certain invention is patented in country A, but not in B (in the latter it should be considered novel and non-obvious). Can a random person (not the original inventor) apply for and be granted a patent in country B on that same invention (thus prohibiting the inventor to produce/sell it in B)?
No Because it’s patented in country A, it is not novel anywhere in the world. That is, the patent in country A is “prior art” that would disqualify it from being patented anywhere else. The original patent holder can patent it elsewhere because patent law has an exception for that.
Ideas (methods of playing, game mechanics, strategy, goals) cannot be protected by copyright. But any part of a creative work can. So, no copying of drawings, patterns, images, sounds, or the element. I suppose copying the software code is not an issue here, but it can, obviously, also not be copied. And nothing in your game can look like someone's else trademark.
No, copyright absolutely does not protect anything "novel" or anything related to algorithms or generally anything functional at all. Copyright only protects your "expressed representation of a creative work". Other people can duplicate your work with a different "expression" and not be infringing on copyright. And if there is nothing creative in your work then it's not even eligible for copyright in the first place. For example, if you figure out how to sort an array with fewer computational steps than what anybody else is doing then that is functional code, not creative code, and anybody can reverse engineer/duplicate your sorting algorithm. However, patents do provide the protection you're looking for. If you want to protect your fancy algorithm then apply for a patent. Patents expire an order of magnitude sooner than copyright, but they are the only means of legally protecting this type of intellectual property. Unlike copyright, patent protection is only available if you apply for it, and it has to be approved by the relevant government department in your country (although you can start using the patented technology before approval has gone through).
Ideas are not protected by copyright, only arrangements of words are protected. If you &quot;rephrase&quot; by only a minor change of wording, leaving much of the wording intact, that is still a copyright infringement unless an exception such as fair use or fair dealing applies (and that seems a bit doubtful in this case). If you &quot;rephrase&quot; so that the wording is quite different, even though the idea is the same, there is probably no infringement. Copying elements of computer code or other IT commands that are essential to making an example work is not infringement. Where there is only one or a very small number of ways to naturally express a fact, copying such expression is not infringement, as facts are not protected by copyright. Adding examples but keeping significant wording unchanged is still likely to be infringement.
Patenting does not require a working product in fields where the performance is predictable before hand. Chemistry and biology do have criteria regarding real results. The description in the patent application needs to be detailed enough that someone of ordinary skill in the field could make and use the invention. After company A gets a patent (might be 3 years or never), it can try to stop company B from making, selling, offering to sell, using, or importing whatever is claimed in the issued patent. You say "does essentially the same thing". If you accomplish the identical goal (speaker identification from noisy audio, for example) but accomplish it by following very different steps, then there may be no infringement at all.
The law of each country where you offer the app for download applies, and you have to consider: Privacy Policy (GDPR in EU, CCPA in California, APPI in Japan, LGPD in Brasil, and more - check each country to be on the safe side) Disclaimer versus AGB/Terms and Conditions (e.g. Germany), not required but recommended Impressum (Germany, Switzerland, Austria) Value Added Tax (VAT) which is taken care of e.g. by Google Play for most countries but not all (e.g. not for Japan) in case the app is not free Consumer Protection Law - applicable (and different) everywhere There might be more, but these are the important ones I am aware of.
Prompted by this recent similar question, I've revisited this question and deleted my original answer as it was completely off the mark. This is its replacement. It is illegal, and it turns out to be an international standard in the Berne Convention. Article 16 in full: (1) Infringing copies of a work shall be liable to seizure in any country of the Union where the work enjoys legal protection. (2) The provisions of the preceding paragraph shall also apply to reproductions coming from a country where the work is not protected, or has ceased to be protected. (3) The seizure shall take place in accordance with the legislation of each country. Your scenario falls squarely within point (2) and the imported George Orwell book is to be treated as an infringing copy within the UK. The implementing UK legislation for (2) can be found in Section 27(3) of the Copyright, Designs and Patents Act 1988.
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”?
