Protecting intellectual property I have a startup and I just sent via E-Mail some sample images to a family member who owns a small marketing and design company in the US. My parents had suggested it since we are on good terms with the person and we trust him. The images I sent are close to what the final product is intended to look like. The first e-mail I received back, within a couple of minutes after I sent mine, asked something to the likes of &quot;Do you have copyright on any of the images or the concept?&quot; Obviously, I do not. It's the last piece missing in the startup. This got me thinking, however. Can he, in theory, copyright what I've sent him? Even though I created it, and he indirectly implied in the e-mail that he's not the content owner, can he attribute my own intellectual property to himself? Can he replicate what my startup does, copyright it, and make it impossible for me to build my own product? I am a Canadian citizen (residing in Canada), so I'm not sure if that makes a difference.
You automatically have a copyright in any copyritable things you create. So you own copyright over the pictures you sent him (as long as you created them)
The DMCA prohibits circumvention of technological measures that effectively control access to a copyrighted work. So you can't legally "crack" the software, period -- even if you own a disc containing the software and have a valid license to use it, a license to use the work is not authorization to circumvent access controls. So if the disc is copy-protected, by my understanding of the DMCA, you're kinda screwed. (The company might be willing to provide you a replacement copy, even if only to maintain the illusion that the software is "licensed, not sold". But you can't make one yourself.) Likewise, if you have a copy of the disc but have lost the license key, you're screwed. Even if you could prove beyond any doubt that you are the licensee, there's not any law i'm aware of that would compel the copyright owner to provide you another license key. And courts have held that distribution of license keys without authorization is a violation of the DMCA. So whoever might provide you another key, if they're not the copyright holder, has broken the law. If you managed to copy the disc from a friend (without circumventing any kind of copy protection), and had your own license key, you might be in a better position. Many EULAs allow you to make a backup copy. Even if they didn't, copyright law does, so there's a possible case for fair use.
The designer/company owns the copyright to the original work, you own the copyright in the derivative work (the screenshot). However, your work is subject to whatever rights your license to use the game gives you and fair use/fair dealing. An example of a company attempting to enforce copyright from screenshots/screen recordings can be seen by the Nintendo Creators Program.
You would want to establish trademark protection on the phrase "Ball Cube": copyright is not generally a good way to protect names or other short phrases. See, for example, Can I copyright the name of my band? from the U. S. Copyright Office, which notes that "names are not protected by copyright law." Furthermore, you're interested in preventing others from selling a similar object using a similar name, and that's precisely what trademark protection is for. The ball cube design would potentially be eligible for copyright protection, but you should be aware that this protection would not extend to elements of its design that originated in Rubik's Cube, because your design would be a derivative work.
The standard for fair use of trademarks is as follows: (1) the product or service in question is not readily identifiable without use of the trademark (2) only so much of the mark as is reasonably necessary to identify the product or service is used (3) use of the mark does not suggest sponsorship or endorsement by the trademark owner. I think you might run into a problem with (1). In other words the trademark owner would argue that you could have used fake trademarks to satisfy your product description needs, so you are using their trademark unnecessarily.
If any elements of the game are protected by copyright, then you cannot reproduce those elements (17 U.S.C. §106) unless your reproduction falls under a fair use exception (17 U.S.C. §107). Elements that may be protected by copyright include: artwork specific language on each card the aggregate effects of the cards (i.e. copying a single card's effects might not infringe copyright, but if you copy the effect of a bunch of the cards, such that you are taking expression of the original author's creativity, that might infringe, even if you change the words used) Whether an element of the game is protected by copyright is a fact-intensive question that would depend on the specifics of the game. Whether your copy infringes is likewise a fact-intensive question that would depend on what you copy. Fair use is also a fact-intensive, case-by-case analysis, but in my opinion, it is likely that creating a computer program derivative work (17 U.S.C. §101) of the game for your own personal education would be considered fair use. From a practical standpoint, even if it were not fair use, it would be near impossible for the copyright owner to discover. Posting the code on GitHub tips the scales away from fair use because of (17 U.S.C. §107(4)): "the effect of the use upon the potential market for or value of the copyrighted work." But, none of the factors are determinative on their own. You ask: I likely cannot simply change all the names of the various cards to something else, right? I agree. In my opinion, the selection and arrangement of the effects attributed to each card is an expression of the author's creativity, and no matter what you call the cards, copyright in the game would be implicated if you retained the effects associated with each card. If I start changing the rules of the game, does that make it legal for me to share my source code, for instance? At some point, it will be an entirely different game, so certainly, in the limit, your work would not be infringing. We can't answer where that line is, but in general, the less of the original author's creativity that you re-use, the less likely a ruling of infringement. Also, in general, the more transformative your work is, the more likely a fair use exception would apply.
Bringing fair use into this sounds iffy if you are partnering -- that is a commercial relationship which should be defined. If they did send you a file with their logo for a specific purpose, you can assume that you are allowed to use it for that specific purpose. If they did not send you the file, you can assume that they did not give you permission, or they would have included the file ...
I assume these are digital photos that were electronically transferred (not prints physically delivered). If they were prints physically delivered, he owns those prints, since you used to own them but you unconditionally transferred ownership to him by giving them. No backsies under the law. The photos are protected by copyright law, which means that the person who took the pictures has the exclusive right to make copies, disseminate them, and authorize making copies. In order for anyone to make a copy, they need permission – a license – from you. In the world of pre-planned business deals, the copyright holder writes up a document granting B some right to use the protected material, which typically means "you can install it on your various devices but may not give copies to others". In this case, however, you didn't create an explicit written license. So if this ends up in court, the question is what implicit license you granted. The courts will not decide that you granted him the license to unrestrictedly sell or give away copies of the protected material. The most likely outcome would be that he can only keep his copy, i.e. he will not be forced to erase the copy that you sent him. What the courts would do is try to discern what license you most likely intended to grant to him. There is a provision in copyright law that allows a licensee to make backup copies of a computer program (17 USC 117), but a digital photo is not a computer program. So the lifespan of the copy that you sent would be the lifespan of the phone (I assume) that you sent it to. Since actually using a digital photo technically requires making a copy (from disk storage to computational memory), there is a legal direction (dead-end) that you could go where the photo could exist on the phone, but never be opened again. Again, the courts would have to discern what license you probably intended w.r.t. ever opening the photo – obviously you intended that the file could be opened / viewed any number of times. You could argue that the license which you granted was conditional, i.e. "you can have and use these pictures as long as we are a thing", but establishing that this was part of the license would be tricky. Free digital content often has some "as long as" condition attached to it, i.e. "you can use this program as long as you are affiliated with University of Whatever". I don't consider a conditional license to be a ridiculous interpretation, on the other hand the particular court (judge) might decide that people who sext should be forced to live with the unpleasant consequences of their decisions. If we exclude such a line of thinking, I don't see a compelling counter-argument that your ex-partner inequitably loses a right by construing the license as conditional. I don't know if there is any case law that addresses this: at any rate, copyright law would severely limit what he could do with the pictures (the tort "invasion of privacy" also limits dissemination).
