Trademark violation for app? I've just received an email from a Turkish app developer who believes my app infringes on his trademark. I've done some reading and read that essentially I'm not allowed to violate any patents or outright steal the work by copying it but otherwise should be fine if portions of the apps match. To elaborate: I'm from Germany, the other developer is from Turkey The app is distributed using the Google Play store (US-based) Both apps provide the same core functionality There are about 40 apps providing the same core functionality The app of the other developer was published in 2015, mine in 2017. My app was created from the ground up and doesn't use any sources of other apps (I created the layout by myself as well) The other developer seems to hold at least some sort of copyright in Turkey: https://i.stack.imgur.com/0DKWO.jpg (blacked out) Both have a very, very similar name. There are 40+ apps on Android alone which share this name as well. There was software prior to both apps with this name. I admit that both apps have a similar main UI (same color, same input elements) which however noticeably differ in design choices, user experience, and scope. But apart from that (the main view), the UI differs completely. Is there any grounds for copyright infringement, if the apps look similar, but the actual sources aren't derived from any sort of original work?
Disclaimer: I'm from the US and don't claim to know German or Turkish law. So let me discuss some general principles here, but details may well be different in Germany and Turkey. You're mixing together three very different things: trademark, copyright, and patent. Copyright protects the expression of an idea, in this case, the exact computer code, images, etc. If you didn't copy his code, the chance that you would coincidentally write identical code is remote. The fact that you both have a line of code that says x=x+1 wouldn't give him any grounds for a lawsuit. He'd have to show substantial portions of the code were identical. If you didn't deliberately copy his code, this isn't going to happen. Barring some extraordinary and unbelievable coincidence, you can't violate copyright accidentally. Trademark protects names and symbols used to identify a company or a product. If you decided to call your software company "Microsoft", then that other Microsoft could sue you for trademark infringement. Likewise if you copied somebody else's logo or other distinctive graphics. This is very different from copyright. It is quite possible to violate someone's trademark accidentally. Especially if he gave his company or product a rather generic name. Like if someone called his product, say, "Password Manager", someone else might make a product with the same name without ever having heard of the original. Ditto if he has some simple logo or other graphics. If you did accidentally duplicate a name or graphic elements, well, in the US a court would likely order you to change your name or graphics and that would be the end of it, unless you refused, in which case you'd end up in court. US Courts have ruled that very generic names have limited trademark protection. An example I saw recently was "Main Street Auto Repair". A court said that the owner of that name could prevent someone else from opening a shop in the same town with the same name, but he couldn't sue someone in another town who happened to use the same name. This is why, by the way, companies often use made-up words for their product names. In your case, this should be a trivial issue. If he is claiming trademark to the look of the main menu screen, just change the colors or move some buttons around. If it actually went to court, you should be able to argue that the similarity was accidental and when you were informed you promptly changed it, and that should be the end of it. Depending, I guess, on how hard-nosed the judge is, etc. Patents are different still. A patent gives the owner the exclusive right to use an invention or process for a specified period of time. It doesn't matter if you invented the same thing entirely independently. Whoever filed the patent first has exclusive rights. There have been cases where an inventor lost out to someone with a similar invention because he submitted his patent application one day later. If this other person has patents that you are infringing, you are pretty much out of luck.
Generally, no, this will not violate copyright. Your end user might violate copyright, but that is their problem not yours. Your program is a tool, just like a word processor is. If I copy a Harry Potter book into a word processor that does not make the word processor maker liable. There is a concept of "contributory infringement", which I think is what you are concerned about. I don't know about Danish law in particular, but most countries would require evidence that you had reasonable knowledge that actual copyright violation was occuring, rather than just being aware that it might happen in theory. This is normally applied to file sharing services who have to have "notice and takedown" measures, file filters and the like. This isn't your concern as you never have any access to the files created by your users. You can also be found liable if you induce anyone to commit copyright violations. Don't draw your customers attention to the custom monster feature as a workaround for those copyrighted monsters, as that could be considered to be inducement. Also don't provide any "wizards" or similar tools which make it noticeably easier to duplicate the custom monsters (e.g. if you notice that the copyrighted custom dragon stats are all on a linear scale with dragon size, don't create a "dragon creation wizard" embodying that fact.) This assumes that your program runs entirely on the end user computer. Its different if you provide any kind of cloud storage for generated characters.
This is permitted so long as it doesn't violate a valid trademark or service mark (or a few equivalent rights in names that are comparable such as collective rights to market beef under the name &quot;Waygu&quot; only if it is produced in a certain area of Japan under Japanese law) that covers goods or services of the same type in the same economic market. A trademark arises either when a term acquires a &quot;secondary meaning&quot; associating its use in connection with a particular kind of good or services in a particular market with a particular provider of that good or that service, or by registration of the trademark or service mark. &quot;Tresh&quot; and &quot;Cassiopeia&quot; are not terms that inherently are related to software, so they are permissible to use as trademarks for software unless someone else already has established trademark protection for them.
Your lawyers should understand that you're dealing with a private company that can make and enforce its own policies when it comes to allowing access to the their store. If Google's policy is to require you to do research and diligence on a possible trademark infringement of your App, that's legal, as long as Google's requirements don't not violate local or national laws of the variant of their store. The idea that another company or individual can allege infringement, yet not communicate sufficiently with you or Google, may not seem fair, but as a response to that, Google can play it safe and not open themselves up to liability by removing your App or making you resubmit under a new name. That is outlined in Google's TOS, which you agreed to. Your only recourse is to keep talking to Google and keep trying to contact the complainant.
Check your license! By operating the original client, you might have agreed to a license, the EULA. Check that license for what it says about you being allowed to do with the product. In a recent case of Bungie vs. Elite Boss Tech, a US court found in a default judgment that a certain cheat software that would interact with both the game's client and the company's servers among other things did... constitute copyright infringement [as a derivative work] was a breach of contract [formed by the EULA and agreeing to the Terms of Service for the game] was interference with Contractual allegations [of other users that obtained the software] However, not all internet games or experiences are locked down like that. Other companies do offer an open API set or terms under which a client's software may be modified. As a very generous example, LindenLabs does for its SecondLife Virtual World, for which they provide not just the framework, but also the terms under which you are allowed to make a third party Viewer Sometimes, the Terms of service are rather hidden. For example, the Chinese Go platform Fox Weiqi operates in china. To get to the terms of service, you need to download the free client, go to Settings (via the cog), then choose 野狐围棋用户协议, which is Chinese for Wild Fox Go User Agreement. This links to https://edu.foxwq.com/complex/useragreement.html. The user agreement is of course in Chinese, but Google Translate manages to get that to English. It contains the following clause: 7.2 Unless permitted by law or with the written permission of Yehu, you shall not engage in the following acts during the use of this software: ( 1 ) Delete the copyright information on the software and its copies; ( 2 ) Reverse engineer, reverse assemble, reverse compile the software, or try to find the source code of the software in other ways; ( 6 ) Log in or use Yehu Go and its services through third-party software, plug-ins, plug-ins, systems not authorized by Yehu, or make, publish, and disseminate the above tools; ( 7 ) Interfering with the software and its components, modules, and data by itself or authorizing others or third-party software While it takes a court to see if the terms hold water and are actually enforceable because of how the EULA is offered, the face value of those clauses is, that it is forbidden unless you have a specific law that allows such or you obtain written permission. With that kind of possible liability that might cost millions, there might be serious legal problems. Read your license agreement and terms of service and consult a lawyer.
Yes Best is to call them and let them guide you to the right department. https://www.microsoft.com/en-gb/contact.aspx In reality you can give up. They will never ever give you the permission to use the icon, even if you'd pay for it. Why? Because as soon they give the permission to someone others will try to use it too and their legal stand would be more difficult since they softenend the use rights of that icon/intellectual property, opening doors for people who copy without thinking of the legal implications and scammers. EDIT: To add; As far I know you're not allowed to take stuff from wikipedia without noticing them/linking to them. That your app is free also doesn't matters. Maybe you're even showing ads in your app giving it a commercial goal.
I will try to answer some of my questions based on recent developments and other information I've seen. Yes. 2. No. On page 23 of this Commerce Dept. memo on TikTok, it describes: This prohibition would remove the TikTok app from U.S.-based mobile app stores, preventing mobile users from being able to download the app to their devices or receive updates. As scoped, this prohibition would only apply to app stores accessible in the United States, thus users would still be able to download the app while outside the United States. On page 15 of this Commerce Dept. memo on WeChat, it describes: This prohibition would remove the WeChat app from U.S.-based mobile app stores, preventing mobile users from being able to download the app to their devices or receive updates. As scoped, this prohibition would only apply to app stores accessible in the United States, thus users would still be able to download the app while outside the United States. 3,4,5. No for WeChat. In letters sent to the opposite party in a lawsuit and filed with the court, the US government has provided assurances that WeChat users will not have any civil or criminal liability for downloading or using the app for personal or business communication. we can provide assurances that the Secretary does not intend to take actions that would target persons or groups whose only connection with WeChat is their use or downloading of the app to convey personal or business information between users, or otherwise define the relevant transactions in such a way that would impose criminal or civil liability on such users. In other words, while use of the app for such communications could be directly or indirectly impaired through measures targeted at other transactions, use and downloading of the app for this limited purpose will not be a defined transaction, and such users will not be targeted or subject to penalties. I'm not entirely sure for TikTok, but the same may be true for TikTok since the prohibited transactions for both are essentially the same. No. The regulations on prohibited transactions do not require the blocking of traffic from the apps. Simply carrying the traffic of the app is not one of the prohibited transactions, as long as the company does not have a contract for internet transit or peering with ByteDance/Tencent, nor are providing hosting or content delivery services to ByteDance/Tencent. On page 23 of the Commerce Dept. memo on TikTok linked above, it says: User data could still be served by data centers, [redacted] operating outside of the United States. On page 7 of this declaration by a Commerce Dept. official further explains that WeChat traffic will still flow through the US: Moreover, this prohibition would not affect Internet transit or peering services in the United States that are not “directly contracted or arranged” by Tencent, and thus would leave the overwhelming majority of Internet traffic, including WeChat data, untouched.
Under US law, and I believe under the laws of most countries, each of the various photographs of the apple would be protected by copyright. Thew initial owner would be the photographer, or perhaps the photographer's employer, in each case. Copyright protects expression, including both words and image. It does not protect ideas. The idea of an apple is not protected. The specific representation of a particular apple would be. If the painter imitates the specific feature of the apple shown in the photographs, to the extent that the painting is a derivative work of one or more of the photos, then the painter needs the permission of the copyright holder(s). Without that permission, creating the painting is infringement of copyright. However, if the painter merely took the general idea of an apple, and created a new expression of that idea, without using any of the specifics of the photos, there there would be no infringement. If the photos were instead images of an imaginary thing, perhaps a dragon, or some invented machine of building perhaps, with the images created by perhaps a compute animation program, or by photographing a model, the legal rules would be the same. If the painter simply used the idea from the photos, there is no infringement. If the painter used sufficient specific detail so that the painting is a derivative work, then permission is required. Exactly how much detail must be used for a work to be considered &quot;derivative&quot; is a matter of judgement -- ultimately the judgement of a court if the matter is disputed. There is no clear bright line making that distinction. That C has commissioned the painter T to create the painting is not relevant, unless C is the copyright owner of the photos, or has secured permission from the copyright owner(s). If C validly grants permission, then there is no copyright issue even if the painting is a derivative work. It does not matter what technique or technical means T uses to create the painting. T may use a brush, a pallet knife, a toy car, drips of paint, or a compute drafting program. If, by whatever means, T creates a derivative work, then permission is needed or else it is an act of infringement merely to create the work. If the work is not derivative, then no permission is needed. Copyright law applies no matter what specific technique the creator of an image uses, provided that human creativity is involved.
