Chances of theft of new invention during the screening process to get a patent Suppose I invented something and need to patent it. So, I submit all the documents to the patent office. So, the officers who examine my documents containing new invention at the patent office, could rob the idea and sell it a other big company and get the money from them and help them to file a patent while delaying my submission. So, they will tell me that there is a previous submission of the same invention and reject mine. Is this a possibility to happen? what kind of measures have taken or can be taken to eliminate such activities? Is there any law to help the inventor?
You don't say what jurisdiction's patent laws you're interested in, and priority dates can differ in different schemes. I'm answering as to U.S. law only. In the United States, under the current hybrid "first-inventor-to-file" system, the priority date--the date that determines who "wins" if there are multiple claims to a specific invention--is, with some exceptions that I won't go into, the date of your first application. In other words, the date that the PTO got it in the mail. Once your application is submitted, it is--again, with some limitations I won't get into--prior art for the purposes of any later-submitted application. They can't get another application later, grant it first, and then deny your application based on the later-submitted application. Your application date would still win out. Could someone in the USPTO slip your application out of the stack, fudge the dates, and convince some other company to submit a similar application to get priority over you? Not as a practical matter, no. The USPTO isn't one guy in a room; it's a large organization, and the person who opens the mail, types in your application details, and sends you a receipt, isn't the same guy who knows whether your invention is any good or not. And, frankly, very few patentable inventions are going to be worth someone risking their job and/or jail time over--especially when there would be significant evidence of the misconduct--for example, your patent agent's files. So what are the chances that the examiner on your patent: 1) Is a nefarious character who has lived a life of public service long enough and wants to go rogue; 2) Has a friend in the mailroom who is also an expert in the field of your invention; and 3) Has a conduct in industry who is willing to break the law for the rights to your invention? Slim to none. And if you have an invention that is really so revolutionary that it's going to be worth so many people risking so much to steal it, odds are there will be other evidence that you were the inventor.
To successfully sue for patent infringement, you need to hold a valid patent. An issued patent is not irrefutable proof that you have a valid patent; patents are presumed valid, but the defendant can raise invalidity as a defense in an infringement suit. One of the conditions for a patent is that the invention is novel (details vary depending on filing date). Even if the USPTO doesn't think there was prior art, that doesn't mean the defendant can't try to convince the court there was prior art. If the defendant proves that the invention was not novel (or any other reason the patent is invalid), the defendant wins the infringement suit. There are a couple ways to challenge the patent for lack of novelty, which can lead to a challenge before the USPTO or before a federal court. If it's challenged before the PTO and found invalid, the holder loses the patent. If it's challenged in a lawsuit and the holder loses, they can never again assert that the patent is valid in any US court (except when appealing that decision or in a few other special cases). So if it's challenged in court and the challenger wins, the patent is also effectively invalid.
I don't know the specifics of this invention, but it's important to remember that the novelty and non-obviousness of an invention is made as of the date of the patent application (or earlier priority date, not applicable here). In this case, that would be September 5, 1979. So you'd have to look specifically at what art existed as of that date (actually, one year prior to that date) and show that the invention was obvious and not novel in light of that prior art. It would take more than a general claim that it's obvious, for example. The practices followed by the PTO in determining novelty and obviousness in accordance with the law is set out in the Manual of Patent Examination Procedure, chapter 700 ("Examination of patents"). You might find that an interesting read. The current release (Ninth Edition, Revision 07.2015) is here; the edition in effect in 1979 would have been the Fourth Edition, here. As an aside, the term of the patent is not 20 years from publication. The term under today's law is 20 years from initial filing date, not from publication. Had that law been in effect for this patent, it would have expired in September 5, 1999 (which it actually did, as noted below). Prior to June 8, 1995, US patent term was based on the date of issue plus 17 years; in this case to January 5, 1999. But under terms of the 1995 law, any patent applied for prior to June 8, 1995 got the greater of those two terms; so we're back to September 5, 1999 again. (And just for completeness, there is also the matter of periodic maintenance fees that today need to be paid to keep a patent in force; but that didn't start until December 1980, and wouldn't have applied to this patent, which was filed prior to the institution of maintenance fees.)
How to send a document restricting its spread? In theory you could have the company sign a Non-Disclosure Agreement (NDA) prior to sharing the details of your project. However, your chances of enforcing the NDA seem negligible except maybe for George White's suggestion about a patent application. It is otherwise in your best interest to think of another way of showcasing your skills set. Assuming that the company signs your NDA, you have no realistic way to prevent the company from misappropriating (i.e., stealing) your idea(s). You will have no access to the company's systems to ensure that it has deleted all copies and records that could result in unauthorized disclosure. Even if you find out that the company misappropriated your information, it could be too late because the statute of limitations expired, and/or too costly --not just in terms of money-- to bring court proceedings for misappropriation.
If you copy copyrighted material without permission or another exemption, you are at risk It doesn’t matter if you know the material is subject to copyright, it doesn’t matter if you think you have permission but don’t, it doesn’t even matter if you knowingly make the copy or if it is some background process you don’t know about. Copyright law is really simple: if you make an unlawful copy, you broke it. If this seems unduly harsh, remember you are dealing with a law with its roots in the 18th century that was internationalised at the beginning of the 20th century. Making copies then was a hard, deliberate process - you couldn’t “accidentally” or “inadvertently” make a copy of a literary or artistic work. Now you can - the world has changed, the law hasn’t.
&quot;become yours&quot; - Which court are you in? The court of the schoolyard? If you're in real court, then You would need to sue, to quiet title When a bona-fide dispute as to ownership exists, a case can be brought before a judge to resolve ownership definitively. The axiom of a quiet title action is that you must notify all parties who could possibly have an interest. Really, notification is 7/8 of it, because by the time you arrive at a &quot;quiet title&quot; action, most likely they either lost interest or are gone. And the crux of &quot;Notify&quot; is that your efforts to notify the party are to the standards of the court. You are a hostile party, noting your interests are in conflict with theirs. (we must fairly assume they want their iPad back; you want to take the iPad). Thus, it is obvious you will prefer to fail in your efforts at contact, and you will do a bad job of it, possibly on purpose. Since parties in a lawsuit are responsible to serve all documents on each other, courts have very high standards for that. And these standards are tested and gamed all the time. I even had a clever plaintiff do it to me! (we were expecting both the appeal and the dis-service). The crux of document service is you hire a licensed, third-party independent process server. A process server is naturally good at skip-tracing (think &quot;Dog: the Process Server&quot;) and is accustomed to finding people who are actively hiding. (because some people think they can avoid consequences by evading service. That's a loser's game generally.) So, when you show up in court and they aren't there, the judge will ask &quot;did you serve them?&quot; And then you say &quot;yes&quot;, name the company, and if needed call the process server to the stand, and the server reads out of their notebook all the things they did to search for the counterparty.
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.
No Let’s assume the most generous interpretation: you came up with a fully fleshed-out idea for a television show - name, characters, plot, scene-setting - the lot. You told this idea over the phone to someone else who made this show incorporating every single part of your idea. Here’s the rub: nobody owns ideas. Unless you had them sign a non-disclosure agreement before you told them (which you didn’t), they are free to use your ideas however they like.
