Up to what point can an OS design and theme mimic another operating system? I am wondering to what point can the desktop theme imitate another, without being sued for copyright violation or plagiarism. Are there any commonly accepted rules in the jurisprudence of what is and is not allowed? Let's take for example the Linuxfx distro, which themes are imitating those of Windows 10 or Windows 11: https://www.linuxfx.org/ The graphical interface looks very close from the one of Windows. Some softwares like Microsoft Edge are available for Linux. So, it is perfectly normal that the exact icon of this browser displays in the interface. But there are other aspects that surprise me more. When looking at screenshots, the Windows &quot;Start button&quot; icon at the bottom left looks the native one (or very close). Some icons, the inner layout of Windows, texts, colors and even the desktop background look identical or at least very similar. As a software is a whole, there is work associated with its design, how can a distro like LinuxFx and its Windows themes exist without being sued by Microsoft for plagiarism / copyright infringment?
how can a distro like LinuxFx and its Windows themes exist without being sued by Microsoft for plagiarism / copyright infringement? It's Microsoft's choice to either sue for copyright infringement or ignore the infringement. Microsoft would weigh the cost/benefits of a lawsuit that would hinge on the judge/jury deciding the fairly gray area of what constitutes enough infringement for LinuxFx be liable and result in damages for Microsoft. Would a judge/jury rule in favor of what Microsoft sees as design and copyright infringement? Or would Microsoft lose and end up with bad PR after spending a lot of money? Or, as ohwilleke mentions: LinuxFx and Microsoft may have a license agreement, so there could already be a legal agreement that LinuxFx can legally &quot;copy&quot; the Microsoft interface.
It is illegal to make copies of copyrighted materials without license. In the case of software, obviously it will be illegal to make copies by copying and installing the software without a license, but we are not talking about that. If I have a legitimate license of say Photoshop, and I start the application, parts or all of the code will be loaded into the RAM of my computer, which is a copy. According to copyright law, it is legal for me to make that copy. You are allowed to copy legitimately owned software into RAM to execute it. If your copy of Photoshop is illegal, and you start the application, the copy that is made into RAM is again copyright infringement. Having read the software license for the software that you get when you buy a Mac, it seems that if you steal my computer and just start the operating system, you are committing copyright infringement, and it seems that if you buy such a stolen computer and just start the operating system, you are committing copyright infringement as well, because the license that I received when I purchased the computer covers anyone using it with my permission, and covers anyone who legally buys the computer from me, but doesn't cover a thief. Now does this affect the work that you did? No, you have the full copyright on your work. Copyright law doesn't require that your tools are all used legitimately.
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.
I suspect contract law will affect the ability to do this. Terms like "USB" and the associated logos etc are intellectual property (trademarks, copyrights, etc) owned by the USB Consortium. If you don't comply with their terms, you probably cannot describe your product as a USB product. THE USB-IF LOGOS MAY BE USED ONLY IN CONJUNCTION WITH PRODUCTS WHICH HAVE PASSED USB-IF COMPLIANCE TESTING AND ARE CURRENTLY ON THE INTEGRATORS LIST. THIS REQUIRES THAT THE COMPANY BE ASSIGNED A USB VENDOR ID NUMBER.
This sounds like a case where there can be differences as to if something is a design that can be copyrighted or if it is a matter of a trademark held by the artist who drew the circle. If someone began a copyright infringement action against you, claiming copyright of the shape of a circle, your defense could be the Threshold of originality (Wikipedia). The threshold of originality is a concept in copyright law (Wikipedia) that is used to assess whether a particular work can be copyrighted. It is used to distinguish works that are sufficiently original to warrant copyright protection from those that are not. In this context, "originality" refers to "coming from someone as the originator/author" (insofar as it somehow reflects the author's personality), rather than "never having occurred or existed before" (which would amount to the protection of something new, as in patent protection). Obviously, circles, squares, triangles, pyramids, etc., even straight lines, have all existed for a long time. Simple shapes can, of course, be included as part of a more complex design, and that design as a whole is copyrighted as soon as you complete the design. You don't need to claim copyright; you already have it. If you did a design that was fairly simple and were accused of copyright infringement, it might come down to a court case to determine the threshold of the threshold of originality. Now, if you did a painting of a circle that looked like another painting of a circle, then you could be accused of trademark infringement, because the artist you allegedly copied could say that they have such a distinctive style that is is their trademark. A trademark, trade mark, or trade-mark is a recognizable sign, design, or expression which identifies products or services of a particular source from those of others...Trademarks (Wikipedia) Trademarks are also designs, of course, but are protected in a different method different than copyrights. So many decisions about copyright infringement come down to the judgement and opinions of a jury, because of the fungibility of what exactly constitutes originality and what constitutes a copy, part of a copy or a derivative. Trademark infringement hinges on how recognizable that design as a mark is and if there can be confusions between the two. For a much more in depth outline of copyright, see I have a question about copyright. What should I read before I ask it? - Law Meta Stack Exchange.
The basic principle about copyright protection is that the expression of an idea is protected, but the idea itself is not. So wholesale copying without permission is infringing. But the abstract algorithm is not protected by copyright (and let us assume that it also isn't patented). By way of analog, an insertion sort is a pretty easy concept to grasp, and once you understand it, you can re-create it, independent of how the original example (where from you learned about the sort) is expressed. So the question is whether it is necessary for you to copy that code (copyright protects against copying), or can you independently re-express the algorithmic idea (ideas are not protected)?
It infringes the copyright. It can easily be proved that both XOR1 and XOR2 derive from the source work by XOR-ing the streams with each other. It's just like any encrypted copy: it infringes the copyright, but only those who can decrypt it are in a position to know that it infringes the copyright. The posts on the forum are illegal because they infringe the copyright; it doesn't matter that they are derived works rather than the work itself, just as your drawing of a copyright-protected image infringes copyright because it is a derived work without being the work itself.
Monopoly is a trademark of Parker Brothers. You would need to get permission to use that trademark. The artwork of the game is copyrighted and cannot be duplicated without violating that copyright. In general, the labels meaning phrases like "Go to Jail" and "New York Avenue" are probably copyrighted and some court decisions have decided that labels are a copyrightable element. However, there is some gray area. The game mechanics are not copyrightable and can be duplicated. What this means is that if you clone the game and use new labels (like new property names and card titles) then you are probably fine. You would have to make a novel board design. If you clone the game, but use the game's labels, then you could potentially lose in court. Of course, remember that corporations will sometimes sue just to intimidate people, even if they have a losing case. Just because your clone is non-infringing doesn't mean they won't sue you. It costs them money to sue people, so if your clone is obscure or not used by many people it could fly under the radar and be ignored by the company. If your clone was a success and became widely used, that would significantly increase the chance you could get sued. In most cases a company will threaten infringers before they sue them, because it is a lot cheaper to threaten somebody than sue them. Therefore, you could make your clone and just plan on discontinuing it if they threaten you. Of course, there is a small risk they would sue you anyway. If you made no money then you are probably safe because it would be a lot harder for them to argue that you commercially damaged them if you made no money.
