How does law define patent worldwide regulation and how does expiration work? I am not from US, also the English is not even my native language, and I am even not a lawyer so it difficult to understand some things. Consider a scrollbar patent . It was patented in US. I have few questions: Basics Although it is patented in US, is it &quot;working&quot; worldwide? Could two countries have the same patent from different inventors? When someone brings patent to patent service in his country, the patent service will check if there same patent anywhere in the world? Basics If last sentence is false, - if someone from country A stole patent from country B, then inventor from country B should go to country A court? How (US) law describes expiration of patent? What does it mean? Can it be repatented? Can anyone free use expired patent? In the page I provided the status of patent is Expired - Fee Related - was does it mean?
For the first question - No, patents are territorial. A US patent is not &quot;working&quot; anywhere else. Of course one can apply in multiple countries if the proper time frames and procedures are followed. There is a mechanism (PCT Treaty) that allows a straightforward way to apply in over a 140 countries simultaneously. Although it is frequently used, it is expensive to continue to prosecute the application in each place and even in high-value inventions only a handful of places are eventually chosen to actually pursue patents. Each country's/region's laws and processes are different and success in patenting can vary. Normally two countries would not have the same thing patented by different inventors. The patenting or publication of the first one would make it prior art to the second filed one. This should be found by the second examiner and stop a duplicate patent by a second inventor. However there can be subtle differences between similar inventions and mistakes do happen. In the case of true simultaneous invention this can happen. To get a patent, the invention must be novel - that means no one has published or patented it anywhere in the world at any time in any language. Before the AIA law in the U.S. the law said &quot;or known in this country&quot;. It could have made a loophole where something was known publicly elsewhere but did not constitute prior art in the U.S. That is now changed to be world-wide. Even if the examiner does a world wide search they might miss something and a patent might get issued even though the invention was not novel and a patent elsewhere is granted. To invalidate it the original patent owner would need to look into available procedures in country A. It might be court or it might be administrative. In most places an annual “renewal” fee must be paid to keep a patent in-force. In the U.S. a “maintenance” fee must be paid at the 3.5 year, 7.5 year and 7.5 year points in order to stay in-force. A patent who’s renewal or maintenance fee hasn’t been paid is expired for fee reasons. That can imply that it can be revived by the patent owner by paying the fees and usually a penalty. There may be a time limit or a small set of allowable circumstances to revive. A patent labeled expired for fee reasons might now be past its normal lifespan and therefore not revivable. In general patents are given to inventors and those an inventor assigns their rights to. Someone else can’t come along and revive a patent they had nothing to do with originally. There is no “re-patenting”.
In your example is the spare part the subject of a design patent? I assume it is not. When you combine the spare part to create a “different product” does the finished product resemble the drawings in the design patent? If, in its intended use, the final thing is close enough to the design patent to fall within its scope then you might by indirectly infringing by inducing people to infringe. The scope of a design patent is very difficult to determine reliably. This has nothing to do with how you got the components of your product, just how the completed thing looks. Copyright does not cover products (unless it is a model of a building or a statue or mold for a statue).
The duration of copyright is specified in the Copyright Designs and Patents Act 1988: 12 (2) Copyright expires at the end of the period of 70 years from the end of the calendar year in which the author dies The only provision for extending the copyright is where is some doubt about authorship. If an unknown author is identified within that 70-year period, then the copyright expires seventy years after the death of the last-surviving author (ibid.) In the case of an artistic work which is presumably verified as being the work of the artist and protected as such, it would be very difficult to suddenly "discover" an unknown contributor who would cause the copyright to be extended.
Under US law, the particular work is not protected by copyright, being a government work. Therefore, an infringement suit in the US would go nowhere. Under the Berne Convention Article 7(8), the term shall be governed by the legislation of the country where protection is claimed; however, unless the legislation of that country otherwise provides, the term shall not exceed the term fixed in the country of origin of the work This is acknowledged via EU Directive 2006/116/EC, Article 7: Where the country of origin of a work, within the meaning of the Berne Convention, is a third country, and the author of the work is not a Community national, the term of protection granted by the Member States shall expire on the date of expiry of the protection granted in the country of origin of the work, but may not exceed the term laid down in Article 1. So unless there is a special provision in the country in question, the shorter of the protection-time of the country of origin and that of the country of lawsuit prevails, i.e. zero in this instance. No jurisdiction in Europe appears to have created a special exception to the effect that government works are subject to copyright protection.
Jurisdiction is generally a matter for courts to decide. For example, in Kernel Records Oy v. Mosley, 694 F. 3d 1294 (2012), the plaintiff, having had their work published in Sweden, had filed a claim there, and lost. They then took the claim to the United States. Copyright infringement is generally actionable per se - no damage needs to actually be proven or sustained. Typically, the rule is that the proper law will apply. This is the state that seems to have the closest and most real connection to the facts of the case. Now, where there is more than one jurisdiction in which a claim may be brought - as in your example - a plaintiff may research the relevant statutes to determine which jurisdiction is most likely to afford them the most favourable outcome. It's called forum shopping. It is likely that the proper law will be that of A or C. This depends on a number of factors: Whether the infringing party profited from the infringement. If the infringing party profited from the act, then you are likely to want to bring the matter in A, so that you can recover damages. Whether the infringing party has any presence in B. If the party has a presence in B, then a claim in B is likely to be more cost-effective. Again, depending on the laws of the country, it may not be possible for the artist to bring a claim against the infringing party if they have no local presence. Some countries have laws that explicitly allow extraterritorial service. Whether the hosting service was aware of the copyright infringement. If the hosting service was aware of the infringement and failed to prevent it, then you may be able to claim for contributory infringement - they could then, depending on their contract/agreement with the infringing party, be able to claim for damages. The Napster case may be somewhat relevant to this, but it's hard to say anything concrete when working with hypothetical countries. At the very least, a claim against the hosting service - which may just be an injunction ordering the removal of the content - could be fruitful. The actual laws of the countries involved. If the artist has sufficient money, they can just choose the forum that is most favourable to them. In short, private international law is a tricky subject and there are so many factors that need to be accounted for.
Under Copyright? The first question is: Is this novel still under copyright. This depends on the place and date of publication. In many countries copyright now lasts for 70 years after the death of the author. Some countries use different rules. In the US, a work published before 1978 is in most cases copyrighted for 95 years. Works published after that are protected for 70 years after the death of the author. More complex cases are detailed in this well-known chart. Who holds the Copyright? For most novels, copyright is initially held by the author(s). The author may sell or give away the copyright at any time. If the author does not transfer the copyright during life, it will pass with other property st the author's death. It may pass by will or by default (intestate) inheritance in the absence of a will. The author's surviving spouse children, if any, are often the heirs to any copyrights, but not always. Authors with many works still in print may have s &quot;literary estate&quot; set up to handle their copyrights. Works with multiple co-authors usually have the copyright shared between all authors; in equal shares unless they agree otherwise. Any one copyright holder may license a derivative work such as a translation. A would-be translator of a work still under copyright must find the copyright holder(s) and obtain permission. If the holders cannot be found, no permission can be obtained, and any translation would be an infringement of copyright. The copyright holder could sue for damages after publication. Damages may be quite substantial in some cases. This varies by country and by the facts of the case. In the US The Federal Copyright Office will search its records to try to determine who holds a copyright. They charge a fee for doing so, and success is not guaranteed. Other countries may have similar services. Addition: There is no automatic or guaranteed way to find who now owns a copyright. In some cases the owner does not even know that s/he owns the copyright. If the holder died without heirs the copyright may belong to the government (state government in the US). Research into the author's life may reveal probable heirs. An obituary may list the author's children, if any. Finding them and asking is a reasonable place to start.
The idea for an app is not subject to copyright. Only the artifacts of the app itself (sourcecode, images, texts, sounds, etc.) can be. So if one only copies the idea and creates their own version of all the other assets, then they are not violating copyright. However, in some cases, ideas can be subject to patents. But patents on software are tricky. First of all, only new ideas can be patented. When a supposed new idea was already published before, then that's called &quot;prior art&quot; and you can not patent it. Then getting a patent means a lot of investment in money and time (which is very different from copyright which you get automatically the moment you make something copyright-worthy). So not everything that could theoretically be patented gets patented. And then, many jurisdictions do not recognize software patents at all, and those which do have different limits on what is and is not patentable when it comes to software. This means patents are rarely a concern when copying the app idea of someone else, but not never. And another possible concern is the third pillar of intellectual property: Trademarks. This protects the name of the app. Trademark law oversimplified forbids to create a competing product with a name which might confuse customers. So if you created StevesSuperCoolAppForCoolPeople and I create StevesSuperCoolAppForCoolPeople - Simplified Edition, then I would be violating your trademark, because my product name sounds as if it was your product, when it is in fact an unrelated product with a similar purpose.
Yes and no. [note, the following is all written about US law. In other jurisdictions laws are, of course, different (though usually not drastically so.)] In the US there are (at least) three different bodies of law that might apply to code: copyright, patents, trade secrets. Copyright covers original expression. Anything you write is automatically, immediately protected under copyright. The copyright applies to the code itself, and anything "derived" from that code. It's up to the courts to decide exactly what "derived" means. One case that's long been viewed as a landmark in this area is Gates Rubber v. Bando Chemicals. The Court of Appeals for the tenth Circuit decision includes a section titled: "The Test for Determining Whether the Copyright of a Computer Program Has Been Infringed." Note that you can register a copyright, and that can be worthwhile, such as helping recover some damages you can't otherwise. Patents are quite different from copyrights. Where a copyright covers expression of an idea, a patent covers a specific invention. Rather than being awarded automatically, a patent has to be applied for, and awarded only after the patent office has determined that there's no relevant prior art to prevent it from being awarded. A patent, however, covers things like somebody else independently discovering/inventing what's covered by the patent. A trade secret could (at least theoretically) apply to some process or procedure embodied in the code. A trade secret mostly applies to a situation where (for example) you're trying to form an alliance with some other company, and in the process tell them things you don't tell the general public. If you've identified the fact that what you're telling them is a trade secret, and they then tell a competitor (or the general public, etc.) or more generally use that information in any way other than the originally intended purpose, it could constitute a trade secret violation. As a side-note: patents and copyright fall under federal law, so they're basically uniform nation-wide. Trade secrets mostly fall under state law, so the exact details vary by state. Absent a reason to believe otherwise, I'd guess your interest here is primarily in copyright infringement. The key here would be showing that one piece of code was derived from the other. That is, it specifically would not apply in a case where there were only a limited number of ways of doing something, so anybody who wanted to do that had to use one of those ways. Since this would not indicate actual derivation, it would not indicate copyright violation.
