Do local patents have precedence over foreign patents even if the foreign patent was granted first? Do local patents have precedence over foreign patents even if the foreign patent was granted first? Let's say that a patent was granted in 2010 after the application was made in the same year, but in the U.S. another company made an application for the same patent in 2020 and was granted the patent in 2021, does the patent in the U.S. have legal precedence in U.S. court over the foreign patent and why?
You may not have a clear understanding of patents. They are 99.9%* territorial. A patent issued by the USPTO is the only patent relevant to the making, selling, offering for sale, importing, or using a patented product in the U.S. And the same for all other countries. Of course U.S. companies not only file for U.S. patents; they also file for German, Chinese and any other places they see fit and have the funds to pursue. Likewise, Chinese companies file with the USPTO for U.S. patents. If a filing by by company A in any country occurs before a filing by company B in any country and A's filing makes B's not new, then B should not a patent in whatever place it has filed. Also, merely getting a patent does not violate someone else's patent, a product can infringe a patent. Actually a product can infringe many patents from many patent owners. And having a patent doesn't automatically allow for the production of a product practicing that patent. (the 0.1% is for odd corner cases at sea or involving importing of components of patented items)
If you're in the USA, this almost certainly falls under fair use, or if you are in another jurisdiction, it almost certainly falls under an analogous exception for educational use. The fact that the excerpt is short contributes to this conclusion. You can also avoid having to rely even on these exceptions by choosing sources that are in the public domain. The specific date before which a work is guaranteed to be in the public domain depends, again, on your jurisdiction, but it's probably sometime in the early 20th century. For example, you're certainly on solid ground if you use Dickens.
If I make a working prototype and upload it on youtube will it prevent others from getting a patent on the idea? Generally yes. If the core information is accessible to the public, it becomes &quot;prior art&quot; and cannot be patented anymore by someone else. That includes you. Depending on local legislation, you have a small time window to apply for a patent (after disclosure) but if you don't, it's public domain and everybody is free to use it. If it's mainly code, you may be able to upload to Github and attach a license to it but that offers only limited protection. Globally? That depends on local legislation which there are too many of, to answer this here.
Congratulations, intrepid legal enthusiast or learner! What you'll need A legal dictionary, especially if you're just getting started. If you don't own one, you can try Black's Law Dictionary A little bit of patience and time. Or maybe a lot, depending on the particular case and the particular question you're trying to answer. Maybe a normal dictionary, too. Again, if you don't own one, there's plenty online. Onelook is a dictionary search engine, so it'll search a lot of dictionaries at the same time. Okay, I've got those things, now what? Alright, there's a few things you should know. Firstly, decisions of superior courts are binding only on those inferior courts within the same hierarchy. This means that you can appeal to a higher court so long as it has appellate jurisdiction. Generally, a state (meaning a country) will have a supreme or highest court, with appellate jurisdiction over all other courts - in Australia, this is the High Court of Australia, in the United States, this is the Supreme Court of the United States, and in the United Kingdom, this is the Supreme Court of the United Kingdom. Secondly, decisions of a court are generally binding only on the matter in dispute. For example, if in a case, the matter of whether the police owe a duty of care to citizens in detecting crime, a comment on whether the police had correctly parked their vehicle is not binding - it is called obiter dictum (plural obiter dicta). What we're looking for in a judgement is the ratio decidendi (plural rationes decidendi), which is the reason for the decision. This is what is binding, and would be considered in future decisions. The problem? It's not always easy to tell the ratio from the obiter. Finally, often, the only way to know whether our interpretation of a case is right is to see whether it is applied in a future case, or overruled. Examples, examples! Sure. Let's try something easy to start with. Do product manufacturers owe a duty of care to their customers? Yes. The decision in Donoghue v Stevenson [1932] UKHL 100 found that product manufacturers - in this case, a ginger beer manufacturer - have a duty of care to ensure their products are safe for use or consumption. Lord Atkin said: The answer seems to be – persons who are so closely and directly affected by my act that I ought reasonably to have them in contemplation as being so affected when I am directing my mind to the acts or omissions which are called in question. Okay, so the answer to this question is yes. How do I verify it? Get the source of the judgement. Without this, you're going to be relying on hearsay. The next best thing is a subsequent judgement that applies the one you're looking for, because if the judgement says what it's supposed to, it'll be mentioned in the subsequent judgement. I've found this one. Decide whether the matter in dispute is actually being decided. In our case, it is. But if I was quoting this from a judgement on whether product manufacturers have an obligation to transfer title for goods supplied on a credit agreement, it wouldn't be binding. Find the quote. If you've been given a quote. Otherwise, grab a cup of tea or coffee and get ready to read. A lot. If you can't find something that says, or means, what it's supposed to, it's probably not accurate. Make sure the judgement hasn't been overruled This is tricky, unless the judgement database you're using has a way of searching it. Most do. In any case, it's much like trying to prove a negative. In fact, it's exactly that. But always check whether the judgement has been overturned on appeal. Make sure the judgement hasn't been obsoleted by statute Again, this is tricky. It's proving a negative, again. And trying to find statute might be an answer for another time. Is that it? Pretty much, I think. These are at least the main points. There's a whole laundry list of things you shouldn't do with judgements, but they're more about reasoning than legal principles. It's a skill you can really only develop by using, and I'm constantly practising myself. Many discussions about cases are precisely about what their effect is. Yes, the decisions and orders are usually pretty clear-cut - for example, the decision is that the manufacturer has a duty of care, and the orders are for damages and costs to be paid. But what it means beyond that can be murky. Luckily for us, judges have become better at writing their judgements so that others can understand. Also, for more important cases, where the entire country, or world, is watching, others will interpret it for you - consider Obergefell v Hodges, for example. Not everyone can be trusted, but everyone, taken together, is a much more trustworthy source than just one person. In the end, there's not a mathematical formula for determining what judgements mean. There's some interpretation involved, some judgement. There's not always going to be one judgement that's enough to prove your matter. I'm struggling to end this post neatly so I'll just finish it with a cliff-
You need a nexus The company doesn’t operate in the USA. Therefore the damage they caused you can’t have happened in the USA. Therefore, no US court has jurisdiction.
To answer the specific questions you asked: Can I use the publication to perform ECC without being under patent protection? Can an academic publication be under patent protection? The answers are: No, that academic paper does not provide any protection from patent litigation. Yes, an academic paper can publish the details of an invention, and that in no way voids the patent. The issue is the timing of the publication; the patent was filed in 1998; the academic paper was published in 2002. Once a patent is filed, the inventors (or anyone else, for that matter) can publish the patent, and that in no way invalidates the patent. To provide any protection against a patent, the prior art needs to be "prior", that is, earlier than the filing date of the patent. Now, this particular issue is made a bit tricky because there does appear to be prior citations of this invention. The whole reason this invention is called the "Montgomery ladder" (not Montgomery multiplication - that's something else) was because it was first published by Peter Montgomery in 1987. One would think that would invalidate the patent. However, I'm not an attorney; I cannot advise you to proceed under that assumption. Instead, I would suggest you follow the advice of Joao; there are plenty of elliptic curve routines out there; use one of them.
If you form an LLC, and then someone later obtains a registered trademark in the same name, the registered trademark would be enforceable everywhere except in the markets and places where the LLC developed common law trademark rights prior to their registration. Your LLC formation would also put a bump in the road in their trademark application. You can, of course, do both, although it is unclear to me why you feel such urgency in the likelihood of an infringement, which suggests that there may be relevant facts that aren't revealed by your post.
Copyright in the US is usually a civil matter. Meaning that the copyright owner can sue (typically for money damages or injunctive relief) an infringer. The criminal laws that we have are aimed at the reproducer and/or distributor. In other words, chances are that you won't get in any criminal trouble for accessing academic articles of dubious origin. But never say never. RIP Aaron Schwartz.
