How and when can protected trademark be broken by someonse else? I have an application called 2oobbllee. I have received an email from owner of the Dobble trademark saying that I infringe its rights. Is it true? I opine that the choice of yours remains disputable. You are flirting with our name and there is no other reason for you to do that other than to capitalize as much as you can with the fame associated to DOBBLE. Are they right? I don't understand that law.
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,
General Rules The rules on this vary somewhat by country. In some counties the is no trademark protection unless a mark is formally registers. In others use &quot;in trade&quot; offers a degree of protection even in the absence of registration. The US follows the second rule. Some of Europe follows the first. But in pretty much all countries trademarks (aka trade marks) are only protected when they are &quot;used in commerce&quot; and are only protected against other uses &quot;in commerce&quot;. This mans that a phrase or design or other possible mark is only protected when it is functioning as a mark, that is it is used by the maker to identify or advertise a product or service (hereafter I use &quot;product&quot; to mean either or both). Moreover a mark is only protected when an alleged infringer uses the mark (or a similar mark) in such a way that people might reasonably be confused into thinking that the infringer's product comes from the same source as the products of the owner of the mark, or is approved, sponsored, or endorsed by the owner of the mark. A simple literary or pop-culture reference is normally not trademark infringement. This is both because a well-known phrase is not usually protectable as a mark at all, and because a reference to it is normally not infringement, even if the mark is protected. The likelihood of confusion is a very important concept in trademark cases. Examples The phrase &quot;Elementary, my dear Watson&quot; Is often used as a reference to the Sherlock Holmes stories and novels. But it was never used to brand or advertise those stories, so its use in a novel or video game now would not be infringement. Even if a game used that phrase as a title, it would not be infringement, because the phrase is not protected. All this would still be true even if the Sherlock Holmes stories were still being published. The tagline &quot;In space, no one can here you scream&quot; was used extensively to advertise the movie Alien. It had some protection as a mark (in the US), and might well have been registered for fuller protection (I haven't checked the US register of trademarks, or any other for this phrase). A game titled with this phrase might well be infringing. A game where a character speaks the phrase at some point probably will not be infringing. Caution All that said, exactly where the limits of infringement lie depend on the detailed factual situation. Before investing sizable amounts of money or time and effort on such a project, it might be wise to consult a lawyer knowledgeable about trademark law in one's particular jurisdiction, and make sure that the risk of suit is not to great for one's tolerance.
The legal issues are too black and white to have any meaningful impact on an ethics discussion. The IP belongs to A and B can't use it. A's not planning to build a product around the patent is irrelevant to the law and I do not see it bring up any ethical issue, but some people who do not understand patent law might. There might be ethics issues if A hired Josh with the specific plan to fire him as soon as the application was filed and intentionally misled him about these plans. Another issue might be Josh's duty to not disclose A's confidential information (the application does not become public right away), and Josh's duty to not draw B into developing an infringing product.
If you use the reviewer's code, or code derived from it (e.g. if you just changed a variable name) then they own the copyright on that part of the software. If the reviewer describes a solution which you implement, or if you re-implement the code from scratch while taking ideas and methods from the reviewer's code, then you own the copyright on that code. However if there are only a few ways to implement something in code then the code is not creative and hence cannot be copyrighted. For example the regular expression in the question you link to is (as far as I can tell) the only correct solution to the problem: any programmer addressing the problem will have come up with that RE. In this the position is akin to a database of phone numbers: while the collection may be copyright (depending on whether selection or arrangement required creativity), the fact that Alice Jones has the number 012345 is not copyrightable, and neither is the alphabetical arrangement of names. Where it gets messy is the boundary between the two. The requirement to detect 4 or more repeated digits in a credit card number could be implemented in a number of ways, but whether there are enough of these to qualify any particular solution as "creative" would be a matter of fact for a court to decide.
The question is always, would a reasonable customer be confused into thinking that the two are the same, or that there is some relation or sponsorship or attribute to one product or firm the rightful reputation of another. That is always dependent on the specific facts and the specific market involved. So-called &quot;famous&quot; marks get extra protection. The exact markets involved will matter. Any stylizations such as colors and typefaces may matter. Logos may matter. I can't say if one of those specific names would be found to infringe on the other.
NO The Names of actual people can neither be trademarked nor can a name have a valid copyrighted. There is no valid market class for names of people, making it impossible to register a trademark in that category. As a result, neither copyright nor trademark will prevent someone from attempting to name a kid &quot;Nintendo&quot; or &quot;Sony Music&quot;. While you could try to name your kid Nintendo, unless you are in the US, most countries like germany or japan do safeguard what you can name a child. Those countries will deny your name as endangering the (mental) health of the child or in other way making the child a target for mockery. Compare to names in all lowercase, line breaks, and infinitely long names.
Can the word &quot;Cola&quot; be used for commercial purposes? It depends on what you want to do with it, but most uses would be permissible. &quot;Cola&quot; is, as you note, a generic term, comparable to &quot;trout&quot; or &quot;sugar&quot; or &quot;beer.&quot; Still, generic words may be subject to trademark protection. Even &quot;coca&quot; is a generic word. Such protection is, furthermore, not exclusive; trademark protection is more subtle and complex than most people realize. There might be a company called &quot;Cola&quot; that operates guided outdoor activities, but that wouldn't necessarily prevent an unrelated company of the same name from pursuing the same business in another jurisdiction. Similarly, it might not prevent a company that repairs household appliances in the same jurisdiction from calling itself &quot;Cola.&quot; For example, in the US, you can buy &quot;Dove&quot; personal care products and &quot;Dove&quot; chocolate; they are sold under distinct trademarks. The central criterion is confusion: trademark protection primarily prevents others from confusing consumers about the source of goods or services. Even if a word or phrase is unambiguously a protected trademark, there are still allowable uses, most notably to designate the product, service, or company associated with the trademark. For example, if someone wants to tell a story about a bottle of Coca Cola (or even to claim &quot;our product is better than Coca Cola&quot;), the owner of the Coca Cola trademark cannot use trademark protection to prevent them from using the phrase &quot;Coca Cola&quot; in the story (or to make the claim). For a specific opinion about a specific use of a specific trademark, you should engage a qualified lawyer with experience in trademark law.
This is a case of nominative use. In general, it is fine to use trademarks to refer to the products trademarked, provided that a reasonable person would not be confused about who creates or provides the product, and would not think that the trademark holder has endorsed, authorized, or sponsored the book or other product that refers to the trademark. It is common to include a disclaimer stating that trademarks are owned by specific parities, and the author or publisher is not claiming them, nor claiming any endorsement or affiliation. Such a disclaimer makes the nominative function of the trade mark use clearer, and would make it harder for the trademark owner to prevail in an infringement suit.
