Is using video games to train computer AI considered fair use? Consider a scenario where I'm thinking of building an automated driving system for my own learning, I use driving simulation video games to aid a specific computer vision module as a test bench since I don't have the financials to actually hire a fleet of vehicles and land. Is this considered fair use? If later on I'm successful in building the system and I want to commercialize it what legal issues can arise? What if I decide later on to use portions of the software for another commercial product?
It's not fair use. Fair use is when you do something that normally only the copyright holder can do. Playing a video game is the ordinary, intended use of the work. In the United States, ordinary use is not protected by copyright. 17 USC 106 sets out the rights protected by copyright. The include copying the work, producing derivative works, distributing the work, and so on. None of these are ordinary use. Someone could perhaps argue that you are creating a derivative work. I doubt that argument would work because you are not taking any protectable elements from the work. But if anyone did argue that, it would make sense to also argue that if that's so, your use would still be covered under fair use because it's transformative, does not substitute for the original work in any way, and takes very little of the work.
You can’t use pictures You can’t use any of these, nor can you make your own art that is derived from these. That’s copyright infringement and there is no fair use defence because you are specifically trying to do something Nintendo already does. You can reproduce that stats of the Pokémon because stats are facts (even if they are facts about fictional things) and facts are not protected by copyright.
The web-browser game was copyrighted the moment it was created by the individual. It did not need a copyright notice to be copyrighted, or a TOS to inform you of copyright. The individual was fully within the law to claim infringement and demand you stop disturbing your mod as an unauthorized change to their game. They should have had a TOS up when they started distributing the game, but that's their choice. The developer could - or have their attorney - send their own legal "takedown notice" of infringement directly to you rather than Tweet about it or approach Google. Google's takedown and your "copyright strike" is different than your original copyright violation and involves Google's TOS - Google Chrome Web Store Developer Agreement | Google Chrome - regarding copyright violations of apps and code under distribution. By your use of the store, Google reserves the right to remove your extensions when there are ...violations of intellectual property rights, including patent, copyright, trademark, trade secret, or other proprietary right of any party,... And, the original game being free and your mod being free rarely matters in copyright law and in cases of infringement. That's something a court would decide on the case and in looking at precedent(s). ...can I get into legal trouble for this? You could be sued by the maker of the game in civil court; that's up to them. Google's recourse is to simply remove the mod from the store and possibly restrict your use of their service(s), according to their TOS.

AD&amp;D, like all games, is covered under copyright. HOWEVER, games are not treated the same as books and other works. Rules of a game, including "stats" and other information required to play the game, are NOT protected by copyright. This is Copyright Law, and has nothing to do with a license which a work is published under. Artwork is fully protected by copyright, as is any setting descriptions. In the context of the D&amp;D franchise, the actual wording of any rulebooks, monster descriptions, game modules, and such are all protected by copyright, so you can't wholesale cut-and-paste things. But, that does not extend to the various mechanics of the game. Armor Class, Hit Dice, etc. are all mechanics, and CANNOT be protected. That includes values assigned to monsters or characters or such. A company cannot also protect the particular layout of those statistics, if that layout is considered generic in nature. In the case we are talking about, a table listing the statistics is NOT protected, as it does nothing more than list those statistics, and contains no original, protected material of WotC. In addition, uniquely created monsters, characters, etc. all have their name protected, but not their statistics. But generic names thereof cannot be protected. It is perfectly permissible to have a clone copy of a Drow and call them a Dark Elf (a generic name). One could not copy the description of the Drow from a Monster Manual, but the idea of a Dark Elf cannot be protected, nor can the statistics thereof. It is explicitly permissible by Copyright Law to clone the rules to a game, which in the context of D&amp;D includes a generic name for anything trademarked (thus, no Drow, and no Dungeon Master, but Dark Elf and Game Master), the mechanisms used to play the game -- including the terms used to reference them -- and all related numerical statistics associated with those components of the game. All of this is in addition to any rights the OGL gives you. These rights CANNOT be restricted by the OGL, as they are basic Copyright Law rights, not license rights. I've been writing D&amp;D expansions and such for over 4 decades now (since the late 1980s), and this is what I've repeatedly been told by various Copyright lawyers. In short, provided you don't use the text description of a particular monster (and instead write your own one, using the same concept of what the monster is), and you don't use a trademarked name for it, it is possible to "scrape copy" the statistic summary section of any Monster Manual or the like. Here's an explicit parallel: the game of Monopoly. When creating a clone of Monopoly, here's what you CAN do: Copy the basic layout of the board - a square with the properties laid out in a path around the edge. Arrange the properties as they currently are, WITH THE CURRENT NAMES on them. Each property's name is not possible to protect, as they are generic names. Free Parking, Jail, and Go To Jail, and Go can all be labeled and placed accordingly. Chance and Community Chest cards can be named as such, and referred to as such. The text on the cards is also (mostly) usable. The costs and values of all Chance, Community Chest, and properties can be copied. The rules of movement, going to jail, etc. can all be copied. Have pieces that are Hats, Dogs, Cars, etc, and both Hotels and Houses, and explicitly refer to them by those names. Here's what you CANNOT do: Use the particular color scheme of the board Use any artwork, including the drawings on any cards. Use the particular graphic presentation of a card. Copy the design of any piece, except the House/Hotel which, insofar as they are very generic, can be extremely similar. You can only use the word "Monopoly" in the context of referring to the Parker Brothers game, not in any other context, as it is trademarked. The specific wording of the rulebook cannot be duplicated. You have to write the rules in your own words. The wording of certain Community Chest and Chance cards, where they are not just generic game instructions, cannot be duplicated. E.g. "Grand Opera Night—Collect $50 from every player for opening night seats" cannot be duplicated, but you can have any other wording for something that would gain you $50 per player. Now, see how that works in comparison to D&amp;D?
Presumably you are referring to works commonly called "fan fiction." Under copyright law these might be considered "derivative works" and therefore subject to the rights of the copyright owner. However, they might also qualify for exemption from copyright enforcement under "fair use." It appears that the legality of fan fiction is not settled law, and the outcome of legal challenges have turned on facts specific to each case. Decent background on the question is summarized on wikipedia.
Since the person who posted the game component under the CC-BY license has no right to do so, no one who used it in reliance on that license had any rights either, and all such uses were at least technically infringement (unless they came under a copyright exception, which seems unlikely). The holder of the copyright on the component could sue in any country where a game using it was published. The details of the law, including the rules on damages and other remidies, will vary from country to country. In the united-states those rules are contained in Chapter 5 of title 17 USC particularly sections 502-505. Section 504 provides for possible money damages. Section 502 provides for a possible injunction (court order to stop infringing). Section 503 provides for for infringing works to be seized. Section 505 provides for possible awards of costs and legal fees to a successful plaintiff (copyright holder). Section 502 allows injunctions to &quot;prevent or restrain infringement of a copyright&quot; on &quot;reasonable&quot; terms. But when the infringement has already been stopped, no such injunction is needed and a court is not likely to impose one. Section 503 allows the court to order the impoundment of infringing copies and &quot;plates, molds, matrices, masters, tapes, film negatives, or other articles by means of which such copies or phonorecords may be reproduced&quot;. This is largely obsolete for digital content. Section 504 is the key. It offers the plaintiff a choice between actual damages plus profits and statutory damages. The rule for the first is: The copyright owner is entitled to recover the actual damages suffered by him or her as a result of the infringement, and any profits of the infringer that are attributable to the infringement and are not taken into account in computing the actual damages. This means money made by use of the unauthorized content, plus any loss of sales or other losses suffered by the owner. Money mad by the infringing work but not made by use of the infringing content is not included, if this can be proven. Income obtained after the infringing content was removed would probably not be included in the infringer's profits. Statutory damages can be any amount between $750 and $30,000 that the count thinks is just, but id the infringement is proved to be &quot;innocent&quot; the lower limit is $200. The exact provision reads: In a case where the infringer sustains the burden of proving, and the court finds that such infringer was not aware and had no reason to believe that his or her acts constituted an infringement of copyright, the court in its discretion may reduce the award of statutory damages to a sum of not less than $200. An award of costs and fees under section 505 is entirely up to the discretion of the court. If the maximum possible award of infringer's profits is $10,000, and a defense of innocent infringement is plausible, a plaintiff might well find such a suit unprofitable, given the legal expenses involved in preparing an carrying through such a suit. But that is entirely up to the copyright owner. An owner may choose to file even an unprofitable suit in an effort to deter others. A person who has discovered that s/he has innocently infringed a copyright and made some money in the process would be wise to document the prompt removal of the infringing content form any publication, and efforts to notify the copyright owner. Ther is no way to be sure what actions the owner will take, if any, within those that the law allows. Often a owner in such a case will not bring suit if the infringement was apparently innocent, resulting profits were small, the infringement has been halted, and future infringement by that infringer seems unlikely. But different owners have different policies on such matters. An owner can delay in deciding whether to file suit or not.
Yes, you may The layout of the board and its appearance are not protected by copyright, because they are not expressions or any other type of copyrightable content. Even if they were (say if some protested art was displayed on the board) you are displaying this for instructional purposes, and not harming any market for the board, so fair use is likely to apply (in the U.S.). The device could be protected by patent, but you are not copying or imitating the board, nor showing anyone how to do so, so that would not apply. You are not selling or advertising the board, nor knock-offs of it, so trademark protection would not apply, even if a protected trademark is visible on th board. Just in case, be sure to make clear that your video is not authorized or endorsed by the maker of the board.
The question as worded implies that if something is a parody it is automatically fair use or allowed in US copyright law. This is a myth. First of all, in a copyright context, the term "parody" is somewhat limited. In that sense, a "parody" is a new work which comments on the original (often but not always by mocking or ridiculing the original). A mere alternate version which modifies the form of the original, perhaps humorously, but not to comment on the original or perhaps on much of anything, is not a parody. A new work which modifies the original to comment on something else, but not on the original, is a satire. Of course many works may be both parodies and satires in this sense. See this law.se Q&amp;A for extensive quotes from Suntrust Bank v. Houghton Mifflin Co 268 F.3d 1257 (The case of The Wind Done Gone vs Gone with the Wind) and discussion of what is and is not a parody in US copyright law, and when a parody is fair use. A parody, because it comments on the original, will often be found to be a fair use of the original. But not always. The full four-factor analysis must still be done, and the results are never certain until a court has passed on the specific case. See this law.se Q&amp;A for more on fair use. I can't tell from the question whether the modified song is truly a parody in the sense used in copyright law. If not, it probably isn't fair use, although it might be for other reasons. By the way, a song written for a television show or video to be distributed commercially is a commercial use, even if a non-profit corporation is involved, and even if there is an educational purpose. Note that fair-use is a strictly US legal concept. Even if something is fair use under US law, it may be copyright infringement under the laws of some other country.
