Is a cease and desist because of a conference talk valid? I submitted a conference talk based in a movie, with the title being a spin-off of the movie title (applied to a technical domain). I have since discovered that there is already a talk form last year with a very similar title, but even though there is this similarity my abstract and the other author's are completely different (and the topics are not quite the same, even though the domain is similar). In result of this I got a cease and desist letter from a lawyer over copyright infringement that seems a bit preposterous. Could an accusation like this have any legal grounds?
It has as much legal standing as the evidence that supports it. See a lawyer to evaluate your position, obviously. But if the evidence is clear that there is no infringement, then the cease and desist letter doesn't mean much.
You're largely correct, though there's some vocabulary you're using that could go either way in terms of proper understanding. My comments on your understanding, presuming we're dealing with two Berne countries (UCC is largely irrelevant these days): My understanding of copyright is that it grants the author an exclusive right to distribute their work in whatever manner they'd like for some amount of time (determined by the copyright duration in a country). Generally correct though there can be many exceptions here (fair use, technical/temporary copying, first-sale doctrine, etc.). Can a person in Country A legally use the adapted work? I'm assuming no [...], Basically correct, whoever holds rights to the original work could theoretically still assert their rights in Country A on any portion of the derivative work that was part of the original. [...] does that mean that the author of the work created in Country B does not technically have all the rights to the work they created, since they have no control over whether their work can be distributed in Country A? This is splitting hairs, but while the derivative author has the rights given to them by copyright law, they aren't absolute. In particular in this case, regardless of which country, they still don't have any inherent exclusive rights over the original work. With respect to country B, those exclusive rights have expired so they don't bind the derivative author, but they haven't expired in country A. If that is the case, then would these rights be &quot;granted&quot; to the author of the adaptation when the copyright finally expires in Country A? Again splitting hairs, but its more helpful to express that no rights are actively granted by the expiration of copyright in Country A, it's just that no one holds those rights anymore (here there might be a language issue too, generally in copyright law &quot;rights&quot; refers to those exclusive actions that may be taken by the copyright holder, and not always to the &quot;right&quot; i.e. &quot;freedom&quot; for someone to do something).
are there any safeguards you could take to preemptively block such behavior, such as a disclaimer inside the book cover that reads something like The safeguard you outline would be overridden as soon as the author enters any contract that requires assignment of copyright. (I would not delve in the differences between licensing and copyright assignment because that hypothetical author is dealing with a contract of adhesion which readily requires assignment; the author has no option to change the ToS to allow for licensing only) Under contract law, one of the essential prerequisites is that the conditions of a contract be entered knowingly and willfully. By deliberately clicking on a ToS page to move forward with the uploading a copyrighted work, the author is signaling his awareness and acceptance of the ToS. The fact that the author chose not to read the ToS is irrelevant and very unlikely to strike whatever entitlements the website owner formulated in the accepted ToS. For the same reason, the author's safeguard disclaimer does not bind the website owner: It cannot be said that the website owner was aware of that disclaimer at the time of the formation of contract between the author and the website owner. That is, the website owner did not knowingly and willfully accepted the author's safeguard. The website owner is not even expected to know about any safeguards which one of its potential user intends to establish. The length of a ToS document is also irrelevant because the website owner has the valid argument that "the user-author could have skimmed through the ToS or do a search (via Control-Find) of keywords such as 'copyright' or 'property', whence any allegation of 'inadvertent' assignment of copyright is untenable". Is there a way to protect your IP from inadvertently being licensed/stolen/assigned via TOS "agreements", without having to waste your life reading huge one-sided online "contracts" that are "subject to change without notice" anyway? Yes. That consists of not uploading one's works in such platforms. In contract law that would be expressed as "declining an exchange of considerations". There are many other alternatives for an author to promote his work without being required to assign copyright.
That depends very much on the specific details. But such a thing is more likely to be held to be fair use if it includes commentary on or criticism of the movie as well as a mere summary of it. Also, 15 minutes of clips seems like a lot, although there is no clear rule on how much can be reused under a claim of fair use. But if the point of the comment and summery could be well made with a shorter set of clips that might improve the claim of fair use. In general, a fair use will use no more of the source than is reasonable needed for the purpose, and will not serve as a substitute for the original work. Being &quot;transformative&quot; is very often cited in case law as strongly favoring fair use. It has nothing to do with making a derivative work original. Any derivative work gets a separate copyright if it has enough original content to satisfy the low requirements of copyright protection, which most such works do. Even an abridgement which adds nothing will generally get a separate copyright.
The copyright owner is whoever first put the material in fixed form. It is most likely that that is the note-taker (you). It is possible (and highly unlikely) that the lecturer read (had memorized) a prepared script and you copied that script mechanically, and if that were the case, he would hold copyright and you infringed by making a copy. Typically, a note-taker follows the logic of a lecture and expresses those ideas in his own words (the notes do not match a plausible verbatim class lecture). Since expression is protected and ideas are not, that makes it most likely that you would prevail in a suit. The equations are almost certainly not protected.
First of all, taking a video made by someone else, making alterations and then distributing the resulting work is probably already a copyright violation. There are exemptions like fair use (check the comments for an example), but just taking a whole video, mirroring it and reposting it without any own contribution very likely does not constitute fair use. The people who do that don't avoid copyright infingement. They just try to avoid getting caught by any automatic system YouTube has in place to detect copyright infringements. But avoiding automatic filters does not mean to avoid DMCA takedown notices, cease&amp;desist letters or lawsuits from real humans who find a mirrored version of their video and feel that their copyright was violated. However, alterations to a creative work can be a creative work in itself. So regardless of the fact that one violated copyright in creating a derivative work, that derivative work might still be eligible for copyright in its own right. That means someone who reposts a video originally made by party A and then altered by party B would violate the copyright of both A and B at once and thus expose themselves to potential legal actions from either party. But the question is if simply mirroring a video constitutes the necessary threshold of originality to make the resulting work eligible for copyright. In most courts, it probably would not.
In my opinion, you are totally free to publish the information. There are two areas of law that can be cosidered - private and public law. In the private law area, you can be liable for revealing trade secrets, but only if you agreed to keep them by a contract. Trade secrets do not exist by themselves (there are minor exceptions, eg. in competition law, but those do not concern us), they must be protected by contracts. Another private limitations, like libel laws, won't apply here. This is not uncommon, but not in cars - you can find clauses like these in software license agreements. Then there is the public area. Is there any regulation, any policy of the state, that prevents you from publishing it? I am not aware you whole legal code of your state, but I doubt there is. It would be a harsh limitation of freedom of speech. Even if the modification could lead to illegal effect (like, modifying toy weapon to kill by rising its power...) it would be only illegal under very rare circumstances. To conclude it - freedom of speech can be limited only if there is sufficient public interest to do so, and I don't see any.
Podcasts and recorded talks are protected by copyright, because they have already been put in fixed form. An extemporaneous radio text (e.g. from a dial-in talk show) does not have fixed form, until someone makes it permanent (audio-records it or writes the text down). A transcript of a podcast is a derivative work, and only the copyright owner can authorize creating a derivative work. So yes, permission is necessary.
