Can you trademark a phrase consisting of common words? Could someone trademark a fairly common string of words, like "This is Your Life" or "Ask [Name]"? My question specifically regards to the naming a podcast — not naming a business. There is a podcast named that, which is fairly popular on iTunes, but if someone else started a podcast with the same name, could the original creator sue? Just to be clear, I do not want to name a podcast with the same name(s) mentioned above or anything along those lines — it's just a general question.
Just Do It. The preceding sentence is one example of a trademark that consists of common words demonstrating that it can be done. As to the podcast if you were duplicating the name of their podcast it would depend on a number of things including if they had trademarked that name, and how Apple's terms of service are for the iTunes podcasts.
A person who uses a name similar to an existing protected trademark may have committed trademark infringement. The trademark owner can sue, and possibly collect significant damages, and possibly also get an injunction against further infringement. Note that this is not a matter of a crime, but of a lawsuit by one person or business against another. (A point of terminology: A trademark, like a copyright, is said to be &quot;infringed&quot; when someone uses it without permission in ways that the law does not allow. The word &quot;broken&quot; is not used for this.) In many countries, only marks properly registered with the appropriate national registry are protected. In the US simply using the mark can lead to its being protected, although registration can give greater rights to the mark owner. Protection in one country does not give protection in another. In general, protection only applies in the same or a similar market area as that in which the mark is already being used. An electronic game may well be similar enough to a card or board game for protection to apply. A key question is how similar a mark can be and avoid infringement. The basic test is if a reasonable person could be confused into thinking that the products were from the same maker, or were affiliated, or that the maker of the original product or service endorsed the new one. This is always something of a judgement call. If a mark is similar enough that a judge or jury might think that some reasonable consumers would be confused or mislead, then there is risk of an adverse judgement. Note that even an unfounded suit may be costly to defend. If there is any question, consulting an experienced trademark lawyer may well be a good idea. I will not express an opinion of the similarity of &quot;2oobbllee&quot; and &quot;Dobble&quot;. That would be legal advice. But if the OP were to change the name of the app, the whole matter would seem to be finished with no risk of court action. Note that the concept of a game, unlike the name, cannot be protected, neither by trademark law nor by copyright law,
Being or not being open source makes fairly little difference in trademark law. If a commercial firm (Yoyodyne, say) had used the name &quot;Portable Network Graphics&quot; and the abbreviation &quot;PNG&quot; in trade, and taken such further steps as would be needed to protect it in the relevant countries, that firm would have a protectable trademark. Note that in some countries, a trademark must be registered to have any protection at all (much of the EU follows this rule). In others, use in commerce can offer some protection even without registration (the US follows this rule). Had this happened (in an alternate reality) Yoyodyne could have sent a cease and desist letter when open source developers started using the mark. If the devs did not cease, Yoyodyne might have obtained an injunction, or damages for trademark infringement, or both. They could also have issued a takedown notie to the site hosting the project. But had Yoyodyne failed to defend the mark effectively and allowed it to become generic, Yoyodyne might have lost all rights to it. Also, had Yoyodyne ceased to use it in trade for a significant period, they might have lost rights. This is a place where the different laws in different countries might lead to different results. Note that &quot;Portable Network Graphics&quot; is rather descriptive, and not particularly distinctive. Descriptive marks, like &quot;Tasty Pizza&quot; generally get weaker protection, while more distinctive marks, such as &quot;LuAnn's Tastee Pizza&quot; are more strongly protected, in general. Again this depends on the country, and the specific facts. In general the first to use, or to register a mark, gets the rights. When one entity is the first to use, but a different one is first to register, things can get confusing, and results will be different in different countries. Note that a Cease and Desist letter is not a legal requirement. It is a threat of possible future legal action, and often an offer to avoid such action if the recipient does as the sender requests. The recipient can comply with the letter, wait for court action, or try to make some sort of compromise deal. Open source projects, as other answers suggest, often choose to comply.
Probably not, without permission. Images of the character are usually copyrighted. The characters themselves are usually protected by trademark. Using the name of a fictional character without permission would imply endorsement by the firm that published works with that character. I've taken day long seminars focused mostly on all of the things that comic book companies do to protect their intellectual property rights in their characters. Of course, if you live in Finland, it is likely that no one in the U.S. would decide to take up the case for a U.S. media property, either because they aren't aware of it, or because it isn't economically worthwhile to pursue.
Yes, they can be. In the example given in the question, there is an additional factor which is that the possibly-infringing company is in a different line of business, which means that it might be possible to use the exact same name without infringing trademark. For example, there are Dove soap and Dove chocolate. (This possibility is probably more remote with a distinctive, novel name such as YouTube.) Trademark protection is supposed to prevent others from confusing consumers. For example, if the graphic design or other branding of the hypothetical youtub were sufficiently similar to that of YouTube that consumers might actually think that YouTube had branched out into the plumbing fixtures industry, then a court would likely find trademark infringement. (Such elements are often protected trademarks in their own right, of course, independent of the world mark; for example, UPS has trademarked "the color brown" in connection with package delivery services.) If a company started using the youtub brand to host and serve digitized video recordings, a finding of infringement is more likely still, even in the absence of other similarities. This would be especially true if it appeared that the name had been chosen explicitly to draw customers from the YouTube site, and that would probably be fairly easy to demonstrate in court.
Yes, the SFC doesn't allow the usage of the term "git" for third-party products unless they have their permisison. From the Git Trademark Policy, 2.3 Prohibited usages of the Marks: In addition, you may not use any of the Marks as a syllable in a new word or as part of a portmanteau (e.g., "Gitalicious", "Gitpedia") used as a mark for a third-party product or service without Conservancy's written permission. For the avoidance of doubt, this provision applies even to third-party marks that use the Marks as a syllable or as part of a portmanteau to refer to a product or service's use of Git code.
Getting permission from the game owner would be a sensible approach. If you get it, great. Then you could do it with the owner's blessing. It's possible to do your write up without the owner's permission, but then you have to be much more careful. For instance, the names of games cannot be copyrighted. No one can prevent you from writing "A Guide to Bridge," or "A Guide to Chess," etc. On the other hand, some games are trademarked, in which case you will need to attach a TM (trademark) symbol when referring to them. In this case, see a lawyer. You are also allowed to discuss the game itself "in your own words," but you must be careful not to "plagiarize" anything from the rules, or the official game description. That is, while you can refer to specific aspects of a game, such as building houses and hotels, the leash on copying is fairly short, as little as five words. This does not refer to five words in a common sequence referring to a single thought like "The United States of America," but it could refer to five words in an original or unusual sequence such as "I think therefore I am," by Rene Descartes, or "X houses and Y hotels," where the numbers X and Y define the number of houses and hotels in a certain board game trademarked (I believe) by Parker Brothers.
You cannot copyright a word or name in and of itself, so you can't sue someone for having a novel titled 13 so long as their novel is distinct from your own. Trademarks can use certain words or word combinations, but often in a way that is stylized or symbolic of a particular unique style and may include font, coloring, and other unique artistic takes. For example, McDonalds cannot copyright or trademark the letter &quot;M&quot; but it can trademark the &quot;Golden Arches&quot; a unique stylized &quot;M&quot; that they use as signage to at all their locations. If the name is a brand of a certain product such, then the name can be trademarked but only with respect to that product. For example, if the Acme Wash-Master is a dish washing machine they can't sue Ace Wash Master, a unique dog bathing system, for using the name &quot;Wash Master&quot; since it's both styled different (Acme uses a dash between words. ACE uses a space) and non-competitive product lines (most people would not wash dishes in a dog bathing device... and one would certainly hope that no dog owners ever said to themselves &quot;Fido stinks and my tub is busted. The dish washer will do in a pinch!&quot;).
