Why are ideas not protected by copyright? Under most (or possibly all) cases ideas are not protected by copyright (or some other IP). Is there a reason for this? It is because it doesn't make sense to protect ideas with copyright?
In United States law, this distinction has been justified by First Amendment values. See Harper &amp; Row v. Nation Enterprises, 471 U.S. 539 (1985). copyright's idea/ expression dichotomy &quot;strike[s] a definitional balance between the First Amendment and the Copyright Act by permitting free communication of facts while still protecting an author's expression.&quot; No author may copyright his ideas or the facts he narrates. If copyright protected ideas, it could effectively prohibit the communication of particular thoughts, topics, facts, propositions, etc. By restricting the protection to expression of those ideas, copyright is giving protection to (and incentivizing) the production of a expressive work in the world. By establishing a marketable right to the use of one's expression, copyright supplies the economic incentive to create and disseminate ideas. However, ideas can be protected by patent. Baker v. Selden, 101 U.S. 99 (1879). The manner of doing something--a process--this is an idea that can be protected by patent.
I would argue that no, there is no copyright for the restored work. Independent copyright is only possible for any original material added, as previously discussed on this site. In this case, the added work was a technical process rather than a creative process, and technical processes cannot be protected by copyright. Copyright licenses would therefore be ineffective. However, I believe one could still impose a license based on owning the copy as opposed to the copyright (contract might be a better term in this case). However, if a third party managed to obtain a copy through some other avenue, any such contract would not be binding on them and nothing could be enforced against them unlike with copyright laws. Another way a license might be imposed is through patent protections, as technical processes can be protected via patents. However, I'm not as familiar with patent law, and this doesn't appear to be the claim being made.
This falls within the penumbra of Feist v. Rural Telephone. The principle articulated there is that facts are not subject to copyright protection, but the expression of facts can be. Quoting from the ruling, "no author may copyright his ideas or the facts he narrates...however, it is beyond dispute that compilations of facts are within the subject matter of copyright". The distinction between protected vs. not protected hinges on originality: "The sine qua non of copyright is originality. To qualify for copyright protection, a work must be original to the author". But it is not sufficient that the work is created by the "sweat of the brow" of an author: it must possess at least some minimal degree of creativity. Thus "[t]he writings which are to be protected are the fruits of intellectual labor, embodied in the form of books, prints, engravings, and the like". As a concrete example, the ruling states "Census-takers, for example, do not 'create' the population figures that emerge from their efforts; in a sense, they copy these figures from the world around them...Census data therefore do not trigger copyright because these data are not 'original' in the constitutional sense." But, compilations of facts can be protected: Factual compilations, on the other hand, may possess the requisite originality. The compilation author typically chooses which facts to include, in what order to place them, and how to arrange the collected data so that they may be used effectively by readers. These choices as to selection and arrangement, so long as they are made independently by the compiler and entail a minimal degree of creativity, are sufficiently original that Congress may protect such compilations through the copyright laws An email list requires nothing more than brow-sweat, and even then, not much. A cleverly annotated and arranged email list would involve substantial creativity and would be subject to protection. That does not mean that you didn't sign some agreement that prohibits you from copying or using the list, but it isn't a matter of copyright.
It doesn't make a difference if the product is free or commercial use, if it's initiated by a company or an individual. What you are considering would be a &quot;derivative work&quot; and without explicit permission from the copyright holder, it is considered a violation.
Ideas aren't property Your employer does not own your ideas. However, neither do you. Ideas are not something that is protected by intellectual property law. To be IP, you need more than an idea. What is IP? The most common types are: Patents - protect inventions and new processes Trade marks - protect logos, words and other branding Copyright - protects art, writing, music, film, and computer programs Registered designs - protects the visual design of a product Circuit layout rights - protect layout designs or plans of integrated circuits used in computer-generated designs Plant breeders rights - protect the commercial rights of new plant varieties. The normal operation of IP law is that if a person is engaged under a contract of service (e.g. an employment contract) then their employer owns all the IP they make which includes progress towards something that might be IP (e.g. all the work that leads up to a patentable invention). However, if they are engaged under a contract for service (e.g. an independent contractor), then the worker owns the IP. The work the employer owns is generally limited to work in the course of the employment. So if you are a software developer they will generally own all code you write that is useful for their business but won't own the romantic novel you write in your spare time. In either case, the specific contract can override the default assumption. What can you do? You can certainly use the idea for the app but you can't use anything that is subject to your employer's IP. That means you can't use any code or copy the user interface - it all has to be redeveloped from scratch. You also can’t develop something that would be of use to their business while you are still an employee.
Assumptions Let us assume that the code involved was created during the period of employment, was within the scope of that employment, and was validly work-made-for-hire (WFH). In that case, the code copyright is owned by the former employer.dn the person who wrote it has no more rights than a random stranger would. I am also going to assume US law. Ownership of Ideas Who owns the ideas, the knowledge of how these libraries work? No one does. In the absence of a patent, no one ever &quot;owns&quot; an idea. ]17 USC 102(b)](https://copyright.gov/title17/92chap1.html#102) provides: (b) In no case does copyright protection for an original work of authorship extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery, regardless of the form in which it is described, explained, illustrated, or embodied in such work. Derivative Works Copyright law does prohibit anyone making a derivative work from a work protected by copyright without the permission of the owner. A derivative work is one &quot;based on&quot; the source work. The classic case is a translation. Exactly when a piece of software is a derivative work of another is fact-dependent. Bu several things are clear. If the source work is trivial and obvious, ther may not be sufficient &quot;originality&quot; for the source work to be protected by copyright at all. If the source work is not protected by a valid copyright, nothing is a derivative work of it. A &quot;hello world&quot; program, for example, is probably not original enough for any copyright. A straight-forward implementation of a basic algorithm like quicksort is probably not original enough, either. If there is only one way, or only a small number of ways, to express the ideas of the source work, the merger doctrine applies. This means that the expression of the work is merged into the idea, leaving the expression unprotected. When the merger doctrine applies, there is, in effect, no copyright. If a work copies ideas from a source, but none of its particular expression of those ideas, the result is not a derivative work, and is not an infringement of copyright. If a work is definitive, but is also a fair use of the source work, it is not an infringement. The usual four-factor fir use analysis must be made to determine this. In particular, if a work is highly transformative, it is likey to be found to be a fair use. Issues from the Question What if the new code (presumably, in the case of something simple) comes out exactly the same (even if I rewrite it without looking)? That Rather suggests that the work was too trivial to be original enough to have copyright protection at all, or else that there are only a few ways to express the idea, and the merger doctrine applies. But if neither o those were true, this might be an infringement. [* To be coninued*]
THE FOLLOWING OPINION IS NOT LEGAL ADVICE Based on your screenshot and description, I don't see anything infringing. If the data you are using is from your own sources, and what you show is not a scan or photo of their guide, and your layout is thus unique in specifics (not a direct copy), it wouldn't be an "infringement" as far as copyright law is concerned. Things you cannot copyright: A font (except as a computer font file but not as used in a document). A concept (a main issue here). A idea for a "way" or "order" to display data. Mere data or facts can not be copyrighted nor can ideas. Anything sourced from the US government (trail data, topos, etc.) Something not in printed, physical, or recorded form. That is, the copyright only extends to those things as they are realized in print, or as a recording for audio or video, or a physical statute, etc. A live performance is not copyrightable for instance, nor are ideas. The Law: In no case does copyright protection for an original work of authorship extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery, regardless of the form in which it is described, explained, illustrated, or embodied in such work. For instance, an icon of a TENT is the common form (like a font) of indicating a camp ground. They may be able to copyright the specific instance of their tent icon, but they cannot prevent you from using some other triangle to represent a tent for a campground. And in facts yours is completely different. Displaying data a particular "way" like 1e for 1 mile east is not copyrightable when it is common for the type of guide. It's just data. CONCEPTS AND DATA ARE NOT COPYRIGHTABLE, only the ACTUAL specific page or work in total as rendered. More below, but your page seems totally different. OTHER FORMS OF IP PROTECTION Now, just because some intellectual property can't be protected by copyright, does not mean it is a free-for-all. For instance, a "way" of doing something can be PATENTED (process patent). And "ornamental design" can be given a design patent. A logo or brand name can be given a trademark. Here's an interesting court ruling on the subject of data display. Basically it can't be an abstraction/concept. It has to be in a definable, physical, novel form. NOTE: it has been possible to copyright a "look and feel" but that applies to software, not static printed media. And the courts have been reversing on that a lot as time goes on. BUT WAIT...THERE'S MORE So, I am going to GUESS that you are talking about AT Guide by David Miller? It's pretty rich of him to claim copyright over the "manner of the display of data" when APPARENTLY he is using concepts of data display as described by EDWARD TUFT So, LOL. Is this the guide they claim you are "copying"?? THESE AREN'T THE ICONS YOU'RE LOOKING FOR Okay, so let's go one by one and their claims against you: 1. The way of representing distances between shelters "The Way" of presenting something is not copyrightable, only an expressive or final form. Some forms of "organization or selection" that may make a work in total copyrightable, but not on their own in isolation. 2. The sideways orientation of the elevation profile Presenting some elements "sideways" is not copyrightable (WTF LOL OMG RUS) the same as number 1. Turning an element sideways does not, on it's own, rise to the level of "creative or non-obvious." 3. The icons Your icons are completely different. If you copied and used his ACTUAL icons, you might have had some issue, but your icons are not even remotely the same. Using icons to indicate services or features is COMMON. Not copyrightable. http://www.dmlp.org/legal-guide/works-not-covered-copyright In general, copyright does not protect individual words, short phrases, and slogans; familiar symbols or designs; or mere variations of typographic ornamentation, lettering, or coloring; mere listings of ingredients or contents. (However, copyright protection may be available, if the artwork of the symbol or design contains sufficient creativity.) 4. The convention of representing direction/distance for waypoints. Again, "The Way" of doing something is not copyrightable, nor is data or facts. 1.1E or 2.3NW are common are they not? I've seen similar treatments elsewhere. It's "obvious and not novel." FINAL FORM, EXPRESSIVE FORM is copyrightable NOT FORMATTING CONCEPTS. Basically, he is saying something along the lines of "I'm formatting paragraphs with a double space, so you can't." The "actual" icon drawings he used are copyrightable. Your icons are clearly different. I assume your mountain-top profile line is taken from some publicly available survey source? So long as you never used a scan of the actual line he uses (and even then?), because he cannot copyright the mountain top profiles themselves! DOES HE EVEN HAVE A VALID COPYRIGHT? For that question, I'd say yes with limitations. His work is a compilation of data. Data can not be copyrighted, but the unique arrangement can in context of the work in total. These three conditions must ALL be present (from http://www.rbs2.com/ccompile.pdf): The collection and assembly of pre-existing material, facts, or data. The selection, coordination, or arrangement of those materials The creation, by virtue of the particular selection, coordination, or arrangement of an original work of authorship. So It seem to be that his guide meets these, but his copyright is for his work in total. You are NOT using his data. You are using your OWN data. Based on my reading of Key vs Chinatown Today you are not even close to infringing. You are doing your OWN selection, and your OWN arrangement. It does not matter that you may be using some similar typographic or charting conventions. Those cannot be copyrighted. You are doing your own thing, and "similarity is not infringement." SEARCH AND YOU WILL FIND On the subject of the copyright, here's the copyright on AT guide: https://cocatalog.loc.gov/cgi-bin/Pwebrecon.cgi?Search_Arg=A.T.+Guide&amp;Search_Code=TALL&amp;PID=FgMjtJ244OxoFULrVoob_CEI8bc_M&amp;SEQ=20190506230418&amp;CNT=25&amp;HIST=1 If the link doesn't work due to expiration or a cookie, it should look like this: It's a matter of using the USPTO search engine "its way" — it's not Google and requires specific search strings. Looks like the assignee or owner is https://antigravitygear.com ? Did THEY contact you or David Miller? Or did they claim to be an attorney? I'd love to see the email. Attorneys don't email dunning letters, by the way (though they may if it was a DMCA takedown request I suppose, but I still doubt it.) If it was an attorney it would be via US mail on attorney letterhead. To the best of my knowledge, you can't file proof of service on an email, it has to be USPS or trackable. This means the guy that made the other PDF is annoyed or whatever. If he claimed to be an attorney, that's VERY illegal if he's not. And one final note: Just being non-profit does not absolve you of copyright infringement. But as I said, I see no infringement here. The other answer that asserted these are covered under "works of art" is not withstanding. There is nothing "expressive" about Miller's guide. Also that other answer cited a source for AUSTRALIAN law, not US. Mere typographic elements do not rise to "an expressive work of art". A mountain profile that is nothing but a illustrative line based on data also does not.
This is not (necessarily) copyright violation It's possible that Quora's usage falls within Fair Use. At the very least, the argument could be made. If it does, then there is nothing that Stack Exchange or the OP can do. Stack Exchange can choose not to protect their copyright Unlike trademarks, which lapse if not protected, copyright endures. Therefore Stack Exchange can pick and choose the copyright fights they want to get involved in and those they don't. If you have brought it to the attention of the copyright owner (or, in this case, licensee) and the copyright owner chooses not to act then you have done all you can and significantly more than you have to do. The OP has copyright I note that one of the examples is your question. As the copyright holder, you are free to issue a DCMA takedown notice on Quora if you feel your copyright has been violated.
