To what extent, and by what legal authority, do patent holders have a duty to share their patents This is a spin-off from Do patent holders have an obligation to make their patents available? To what extent? and particularly from this answer by Robbie Goodwin. In that answer Robbie Goodwin asserts that: patents exist to help their holders exploit whatever it is, without sharing. In an exchange of comments following this answer, the same user asserted: That patent holders are protected from the worst excesses of sharing their knowledge does not give them any duty to share. and later asked: If you [think] patent holders have a duty to share anything, where is that written? What d'you think &quot;others can make use of the ideas without infringing the patent&quot; means? Keeping all this in mind: To what extent do patent holders or applicants have a legal duty to share their knowledge and discoveries with others, or with the public at large? What laws or legal regulations impose such a duty? How can others benefit by such disclosures by the patent holder, during the term of the patent, without infringing the patent? How can others benefit by such disclosures by the patent holder after the patent expires? I am hoping for answers that cite law, case law, or other reliable sources. I am particularly interested in US patent law, but am also interested in the law for any and all other jurisdictions, and answers based on the law of any jurisdiction are welcome.
The constitutional basis for all US patents is Article I, Section 8, Clause 8, of the US Constitution, which grants Congress the power: To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries. See &quot;Intellectual Property Clause&quot; from Cornell's WEX Legal Information Institute. US Patent law requires an applicant to include with a patent application &quot;disclosures&quot;. As the page &quot;Patent Disclosure: Everything You Need to Know&quot; from UpCounsel states: [A] patent disclosure is a public claim of data about an invention. In general, it is any part of the patenting process in which data regarding an invention is disclosed. A good disclosure tells someone else how to create the product. [Emphasis added] The U.S. Constitution gives Congress the right to offer exclusive rights to people for their inventions for set periods of time. This is only if and when the inventor agrees to adequately disclose the invention in writing. [Emphasis added] A formal patent disclosure ... stipulates a set of claims regarding the invention, as well as other data that reveals the unique nature of the product. It should be expressed in writing with the United States Patent and Trademark Office (USPTO) as part of the patent application. What Is Included in a Patent Disclosure? The Specification. A primary disclosure or &quot;specification&quot; is a main document in a patent application. It describes the ways in which the invention is innovative compared to similar inventions and explains the scope of monopoly the applicant believes he or she has to the invention. The specification describes the item and the way to make and to use it, in clear and exact terms. Someone in the field must be able to reasonably create it with these instructions. Further, the specification notes the patent application filing date on which inventor can the rely. It also offers evidence that the invention belongs to the person in question. The Enablement. This explains how to create the object and how someone in the field can do so. The instructions cannot be vague or unclear, but must be exact and detailed. When the patent expires, the enablement should still be usable. This section should include any figures or drawings, with explanations. Again, you will want to show how your invention is special. So, you might want to include many details and different variations of the invention. Later, many of these variations may be deleted from the document as unnecessary. This section may be numerous pages long. Best Mode Requirement. The path revealed must be the best way of creating the item within the author's awareness at the time of filing. Therefore, it may include specific or unique techniques. There should be no concealment. A poor-quality disclosure can risk the appearance of concealment. [Italics added] Claims. This area tells the reader the exclusive rights the patent offers to the inventor.... The official page &quot;Duty of Disclosure, Candor, and Good Faith&quot; from the USPTO cites 37 CFR 1.56 on the duty to disclose information material to patentability. This regulation provides, in the relevant part: A patent by its very nature is affected with a public interest. The public interest is best served, and the most effective patent examination occurs when, at the time an application is being examined, the Office is aware of and evaluates the teachings of all information material to patentability. Each individual associated with the filing and prosecution of a patent application has a duty of candor and good faith in dealing with the Office, which includes a duty to disclose to the Office all information known to that individual to be material to patentability as defined in this section. The duty to disclose information exists with respect to each pending claim ... These disclosures include the state of prior art, as kown to the applicant and the applicant's associates. The page &quot;BEST MODE: Noncompliance with the Duty of Disclosure is Not an Option&quot; states: When you apply for a patent in the United States, you have a legal duty to disclose prior art that could be used to reject your application — in essence, information that may be used against you by the examiner of your application. While persons accused of a crime have a right to remain silent, so as to avoid self-incrimination, inventors applying for a patent have no such right. To the contrary, an inventor’s failure to comply with the duty of disclosure risks any resulting patent being unenforceable. The page &quot;THE PATENT BARGAIN AND THE CURSE OF RETROACTIVITY&quot; states: One of the requirements for the USPTO to issue a patent is that the applicant’s claimed invention be fully disclosed in the application and published in the patent. This is sometimes referred to as the “patent bargain.” This is at the opposite end of the spectrum from trade secrets law, under which a company can sue for © misappropriation of a trade secret but only if it takes reasonable measures to maintain confidentiality of the trade secret. ... Under patent law an inventor must fully disclose his or her invention before enforceable patent rights come into being. This disclosure requirement is sometimes termed the “patent bargain,” under which an inventor gains the right to exclude others from practicing a patented invention in exchange for disclosing the invention so that it may be known by the public and indeed practiced after the patent term has expired. ... [Emphasis added] In general a patent application is not just a description of a specific industrial process. It includes the research by which that process was discovered or developed. That research can benefit others in the same field, and so &quot;promote the progress of science and the useful arts&quot; in helping others to do further research and make further discoveries, which can often be done without infringing the patent itself. Of course, once patent protection expires, anyone may use the patent, and the final patent documents are supposed to include sufficient information that &quot;one skilled in the art&quot; will be able to build the invention or use the process that had been patented. This is in contrast to the situation which would exist had the inventor retained the discovery as a trade secret. In that case no one would have been able to use the patented discovery until some other person independently discovered and disclosed it.
In the US, the author would be able to wind an infringement lawsuit against the re-publisher. Title 17, the US copyright law codified, grants the author the exclusive right to authorize republication, and does not require that a person use their real name. The argument "It was on the internet, it's in the public domain" is utterly without legal merit. The same goes for the assertion that a person loses his rights if he is uncontactable. The author has stated the terms of the license, so there isn't even a reasonable argument that the infringement is innocent (unknowing: "I thought it was with permission). There is no requirement that you have to allow a potential user to hassle you about the license terms. The one thing that is special regarding anonymous and pseudonymous works is that under 17 USC 302, "copyright endures for a term of 95 years from the year of its first publication, or a term of 120 years from the year of its creation, whichever expires first". For a work whose author is identified, copyright "endures for a term consisting of the life of the author and 70 years after the author’s death". This assumes that the host site has not preempted author's license: Stack Exchange, for example, preempts an author's exclusive right, so you can copy stuff from here accorting to the SE terms of usage.
The Person and the University do need to come to an agreement. Universities usually have clear guidelines and arrangements for intellectual property, eg. In line with UK legislation, the University owns all intellectual property or other materials developed by its employees, unless explicitly stated otherwise. Students are not employees of the University and therefore legally own any intellectual property arising from their research as long as all of the creative intellectual input has been that of the student. When a researcher is both a student and an employee ownership of intellectual property will normally be determined by whether the intellectual property was created during the researcher’s duties as a member of staff or a student.

Anything that helps you with your business and that you keep secret is a trade secret. The "keeping it secret" is an important part. Competitors are free to discover the same information themselves and use it, but stealing it from you is illegal. If a contractor needs to learn this information to do their job, you make them sign a non-disclosure agreement or confidentiality agreement which forbids them to pass that information on. That way, it remains a trade secret. If the contractor gives your trade secrets away, that is breach of contract and you can sue for damages. If a competitor pays your contractor to give them your trade secrets, that's not just illegal, it's criminal. On the other hand, if the contractor puts the information on his blog for example where everyone can read it, without having been enticed by someone to do this, then I believe your trade secret is gone and competitors can use it. Same as if you left documents on a park bench and your competitor finds them and reads them. You have to keep a trade secret a secret; if you fail to do so you lose. Asked about patents: If there is a non-disclosure or confidentiality agreement in place, then nobody can apply for a patent. The whole idea of a patent is that you get legal protection in exchange for disclosing your invention. Applying for a patent would mean violation of the non-disclosure agreement.
In principle, every single copyright license allows someone to do something that plain copyright law wouldn't allow them to do. Very often there are conditions: They are allowed to do X, which plain copyright law wouldn't allow them to do, but only if they fulfil some condition Y. The consequence is that if they do X without fulfilling the condition Y, then they are committing copyright infringement. Details are different from country to country. In the USA, you cannot force someone to do what the license asks the, to do, but if they don't, it's copyright infringement, and you can sue them and ask for damages. Other countries see it as a contract, where by doing X they agree to do Y as well, and not doing it would be breach of contract. Often with the interesting effect that you as the copyright holder cannot prove that they accepted the license, so in court they can tell the judge whether they were committing copyright infringement or whether they are in breach of contract. You can of course use your own license - however, one of the standard licenses mean the license was likely checked by a better lawyer than you would want to pay, and is much more likely to achieve what you want to achieve. If there were any problems say with the Creative Commons license, people would have found those problems and fixed them a long time ago.
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.
On what grounds would you sue? Contract Well, I think that you would struggle to find the necessary elements (see What is a contract and what is required for them to be valid?) In particular, you would struggle to prove that there was intention to create legal relations on their part and possibly on yours. Are you able to identify in your "back &amp; forth" a clear, unequivocal offer and acceptance? Without knowing the details of the "back &amp; forth": I was hoping that someone at $organization might be willing to write an article explaining what you do, the history of the organization and how it works appears on the face of it to be a request for a gift; not an offer to treat. Promissory Estoppel If you don't have a contract then it is possible (IMO unlikely) that they induced you by your actions to commit resources (your time in writing) in anticipation of a reward (them publishing what you wrote). To be estopped they would have to have known that you were writing the article in the expectation that it would have your organisation's name in it, that they did not intend for that to happen and that they allowed you to invest those resources notwithstanding. If you can prove all of that then you can require them to do what they promised. The big difficulty I see in this is did you tell them that a) you were writing the article, b) it would have your name in it and c) you expected it to be published in that form. Copyright If they publish the work or a derivative work without your permission you can sue for breach of copyright. As it stands, they probably have an implied licence to publish and you would need to explicitly revoke that. Options There are two reasons to go to court: Money Principle If you are going to court for money then this is at best a risky investment and at worst a gamble: balance your risk and reward carefully. If you are going to court for a principle then I simultaneously admire your principles and think you're an idiot. Make a deal Explain that the reason that you wrote the article was a) to support their fine publication and the fantastic work it does (even if you don't) and b) to garner good publicity for your organisation. You understand and admire their strong editorial stance (especially if you don't) but the article involved a considerable amount of work and could they see their way clear to give you a significant discount (~80%) on a full page ad facing the article.
Whenever there is a license to share things, the license creator wants the license to be widely used, but absolutely does not want slightly different licenses that could be used to trick people, or that just cause legal problems when used. Normal copyright law applies. And for the reasons above, the GPL license as an example allows you to copy the license verbatim but absolutely doesn’t allow you to make any modifications other than changing who is the person licensing a work. I would be curious what happens legally if someone licenses something with a sneakily modified copy of the GPL and then makes claims against a licensee who assumed it was the original GPL.
