Depending on the actual situation, whether these words are registered or not. (1) For a non-well-known trademark, using the same words on the same or similar goods and services will constitute trademark infringement. According to the law, there are two main criteria for judging whether the logo used by a trademark infringes on the exclusive right of others to register a trademark: 1. Judge whether the goods or services used in the registered trademark are the same as or similar to those used in the accused infringing mark. If it is not the same or similar, it can be considered that it does not constitute infringement (cross-category of well-known trademarks) 2. After the goods or services used by both parties are the same or similar, it is necessary to further judge whether the two trademarks are the same or similar and whether there is the possibility of confusion, so as to judge whether there is infringement. First of all, it can be affirmed that trademark approximation is a concept in trademark law, which refers to the similarity of font, pronunciation, meaning, composition, coloring and appearance of two trademark words, or the similarity of the overall arrangement and combination of words and graphics, or the similarity of the shape and appearance of their three-dimensional signs, or the similarity of their colors or color combinations. When used on the same or similar goods or services, it is easy for the relevant public to misunderstand the source of the goods or services. The determination of the same trademark should first determine whether the goods or services designated for use belong to the same or similar goods or services; Secondly, we should judge whether the trademark itself is similar from the aspects of its shape, sound, meaning and overall expression, and take the general attention of the relevant public as the standard, and adopt the method of overall observation and comparison of the main parts. (2) For well-known goods, that is, not using the same words on the same or similar goods and services constitutes infringement. Because of the huge investment and foreseeable economic benefits contained in well-known trademarks, well-known trademarks have long been coveted by illegal infringers. Therefore, the identification of well-known trademark infringement is different from that of ordinary trademarks, and the former has a wider scope. Because the protection of well-known trademarks mainly starts from two aspects: horizontal and vertical, it expands the scope of identification similar to well-known trademarks, vertically expands the categories of goods or services marked by well-known trademarks, and expands from the same or similar goods or services to non-similar goods or services, thus achieving the purpose of giving special protection. To sum up, trademarks exist to better protect their own works, but for unregistered Chinese fonts, they will not constitute infringement. Therefore, as a citizen, when dealing with their own affairs, we should see whether there is infringement, so we will not bear any legal responsibility.
