Before registering a company, we need to check the name of the company. We can find the existing company name through various products. If it is similar to the company name we want to register, but it belongs to different regions, what rules can be used to judge the possibility of passing the company name?

First of all, the company name consists of administrative division, brand name and industry, which can identify the source of goods. After the company is registered, it enjoys the right of enterprise name. According to Item (3) of Article 5 of the Anti-Unfair Competition Law of People's Republic of China (PRC), it is an act of unfair competition for an operator to use someone else's enterprise name without authorization, which makes people mistake it for someone else's goods. Paragraph 1 of Article 6 of the Supreme People's Court's Interpretation on Several Issues Concerning the Application of Laws in the Trial of Civil Cases of Unfair Competition stipulates that the name of an enterprise that has a certain market popularity and is well known to the relevant public can be recognized as the name of an enterprise specified in Item 3 of Article 5 of the Anti-Unfair Competition Law. In this problem, when the subject, as a late-registered actor, uses the name and font size of the previously registered enterprise in its registered enterprise name, unless the previously registered enterprise proves that its font size is well known by the market and the relevant public, it is difficult to identify the infringement of the subject's registration behavior. It should also be noted that the judgment of market well-known and relevant public knowledge is a relative standard, and the protection scope of enterprise name is [KEY_ 14] standard.

Therefore, having a certain market popularity and being known by the relevant public is a prerequisite for the font size in the enterprise name to be protected by China's anti-unfair competition law. The criterion for determining the above premise is mainly whether it belongs to a well-known trademark in China. In addition, statements issued by trade associations, investment certificates of enterprises in marketing advertisements, and popularity questionnaires can all be used as supplementary evidence.

To sum up, under different administrative divisions, unless the subject uses someone else's name and the right holder proves that the name is well known to the relevant public in the market, it is difficult to identify it as infringement.
