Text: What is a well-known trademark? Well-known trademarks, as the name suggests, refer to trademarks that are highly famous and well-known to the public. “Well-known trademarks” come from the Paris Convention for the Protection of Industrial Property, which stipulates that member states should undertake to provide greater protection to well-known trademarks than ordinary trademarks. In this sense, "well-known trademark" is a legal concept rather than a conventional title, and "well-known" in Chinese is originally used as a verb, that is, it means to spread and make a name, and cannot be used as a noun. In life, the word corresponding to "well-known trademark" is "famous brand", but the two are only similar and not the same. First, a well-known trademark refers to a trademark that is well known to the public in a large area of ??a country. There are no local well-known trademarks. "Famous brands" include "national famous brands" or "provincial famous brands" or "local famous brands". Secondly, well-known trademarks refer to trademarks, while famous brands sometimes do not refer to trademarks, but may refer to company names; thirdly, the identification of famous brands has no legal basis in China and is just a daily life term of the public. Well-known trademarks can only be recognized by the Trademark Office of the State Administration for Industry and Commerce or the People's Court. Without such recognition, they cannot be called "well-known trademarks"; fourth, and most importantly, there is no legislation to protect "famous brands", and Well-known trademarks are protected by corresponding laws, regulations, rules and international conventions, which can effectively prohibit unfair use by others.
