Can I use a registered trademark in a software to indicate a file type? I develop a software that contains a file viewer. For the sake of usability I would like to indicate also the &quot;file type&quot;. Let's assume I display a Photoshop file. Am I allowed to refer to the file as &quot;Adobe Photoshop File&quot;? Technically I use a trademark in my application which I don't own. I am just wondering what my options are here. Thank you!
Under United States law: Using a trademark solely to refer to files compatible with a trademarked program would be allowed under the doctrine of nominative fair use. The Ninth Circuit sets out the three-part test for nominative fair use in New Kids on the Block v. New America Pub, 971 F.2d 302 (9th Cir. 1992): &quot;[T]he product or service in question must be one not readily identifiable without use of the trademark&quot; &quot;[O]nly so much of the mark or marks may be used as is reasonably necessary to identify the product or service&quot; &quot;[T]he user must do nothing that would, in conjunction with the mark, suggest sponsorship or endorsement by the trademark holder.&quot; Simply referring to the name of a trademarked program to describe its file format (and not doing so in a way that suggests &quot;sponsorship or endorsement by the trademark holder,&quot; such as slapping a &quot;Certified Adobe Photoshop Compatible&quot; sticker on the box or something like that) would meet these requirements. The International Trademark Association elaborates a bit on the doctrine and gives some examples here.
Your question lacks some details. So you registered a domain name, and later find someone else used that domain name (in the past) for a hobby website? Then no, you don't need to worry about it. If that person has a current trademark on the name used in the domain name, and your website provides/sells products or services in the same area, then you could have a problem. But that doesn't sound like it's the issue.
You infringe a trademark when you use it in a way that allows confusion between your goods and services and their goods and services. Trademarks are limited by geography (although global brands are ... global) and industry. You can use the word “apple” to sell, say, apples or plumbing services, but not computers or consumer electronics. You can also use the trademark Apple to identify goods and services made by Apple - because that’s what a trademark is for. You can’t use it in a way that people could be confused that your goods and services are their goods and services or are related to or endorsed by them.
The images as displayed are quite similar, similar enough that one could violate the copyright of the other. But that is not enough to know if there was in fact a copyright infringement. There are several possibilities: Although using different names, the developers could in fact be the same company. One developer might have obtained permission to use the image from the other. Both images might be based on the same 3rd-party image which both are using with permission. Both images might be based on a public domain image. Copyright is only infringed if a protected work, or a derivative version of the work, is used without permission from the copyright holder. Without knowing who the rights-holder is, and if permission has been obtained, one cannot know if an infringement has occurred. There is no independent or 3rd-party entity that checks for copyright infringements. By the way, the similarity here is close enough that there might also be an issue of trademark infringement. But again, infringement requires use of a protected mark without permission, and so some of the same possibilities arise. (The source of a trademarked logo doe not matter. On the other hand there cannot be trademark infringement unless the mark has been registered, or actually used in commerce. If the same image is used on products in very different industries, say games and hammers, there may or may not be infringement.)
is contract text itself subject to copyright? What are my options? It largely depends on the originality of your contract. C &amp; J Management Corp. v. Anderson, 707 F.Supp.2d 858, 862 (2009) points to multiple references against preclusion of "a copyrightable interest in a contract". But you would need to prove that your competitor copied "original elements" of your contract including "a minimum degree of creativity and originality required to support a valid copyright". See Donald v. Uarco Business Forms, 478 F.2d 764, 766 (1973). Your post provides no information that would help identifying or ruling out this issue in your matter. Without realizing, you might have paid dearly for boilerplate language that your lawyer copied from somewhere else. Indeed, there is so much regurgitation and copy/pasting in the legal "profession" (judges included, as is notorious in judicial opinions they release and in the similarities --verbatim-- among the procedure law of many, many U.S. jurisdictions). That regurgitation is not bad in and of itself, though, since what matters is the expeditious administration of justice and the protection of your rights, rather than obtaining creative expressions authored by some lawyer. You might end up wasting valuable energy and money if you went after the competitor for something like this without first assessing the extent of originality in your contract. Focus instead on the much more detrimental fact that your competitor "plays dirty in general".
The software being free and open source has no impact on whether it infringes any patents or violates any copyrights. Copyrights attach to fixed representations of creative work in a tangible medium (e.g., the actual code and graphical elements of the software in question). As long as you aren't copying the copyrighted work of someone else, you should be in the clear. So, if you write your own code from scratch, or rely on code that you're allowed to use (e.g., "free" software with a permissive license that allows it to be used freely), you should be fine. On the other hand, if you copy a chunk of code that you aren't allowed to use, and then change the variable names so that it's superficially different, you're likely violating someone's copyright. Patents are a much more difficult question. To determine whether you would infringe any patents, you would have to read the independent claims of every patent that might be related. If you perform all the steps of any one of those claims, then you are infringing that claim (and therefore, the patent in which it is found). Unfortunately, this is much easier said than done. First, it may be difficult to search for all the potentially relevant patents, and once you've found them, there may be far too many to read. Second, claims are written in a type of language that is specific to patents, and someone without experience in patent law may not understand them correctly. Finally, the terms in the claims may not take on their plain English meaning, but rather may have been defined by the language in the rest of that patent, so it's possible that you might incorrectly think you were in the clear based on a misunderstanding arising from that. All that said, it may be best to go ahead with implementing an idea and then waiting to see what happens. Chances are that the implementation will arguably infringe some patent in some way, no matter what's done. But chances are also high that there will never be any worrisome enforcement action taken against it by a patent owner, simply due to the difficulty and expense associated with enforcing patent rights.
No It says right on the page you linked: These downloads are not public domain, as they are parts of content that has already been licensed and distributed. Although using these downloads may be permissible as long as the project itself falls under the rule of "Fair Use," it is ill-advised to use these downloads for any project intended for profitable gain or commercial advertisement, unless otherwise stated by Kyutwo.com.
All of your works would be considered to be a derivative work. This is because your work, is based on the work of someone else's. A good test for this to see if something is a derivative work is to see whether the new work can effectively exist without the original. Most copyright laws worldwide are similar, thanks to the Berne Convention for copyrighted works. Since derivative works are normally a right that is exclusive to the copyright holder, you can't make such works without permission (generally through a license or expiry of copyright). So now, let's take a look: The Mona Lisa was made hundreds of years ago. It's definitely in the public domain. You're in no breach of copyright laws here. Yes, of course. Microsoft retains copyright on their icons, and possibly trademarks as well. However, they may have trademark guidance that allows you to use their icons - as long as you follow it. Likely the same as microsoft - you can assume it's similar for most large companies. Code is copyrighted as a literary work - the layout and visual aspect is copyrighted as an artistic work. That artist retains copyright, unless you obtain the work with a license, or the copyright is expired. If you create a derivative work, you infringe on their rights.
