Legal analysis: trademarks are regulated by the Trademark Law, and enterprise names of enterprises with business licenses are regulated by the Regulations on the Administration of Enterprise Name Registration, and the protection of the two goes hand in hand. Therefore, after the service trademark is registered, the same enterprise name that has been used by other enterprises in the same industry before can still be used. At the same time, after the service trademark is registered and approved by the industrial and commercial department as the font size in the enterprise name, the enterprise can also use the same characters. Trademark exclusive right and enterprise name are two different rights, which are regulated by different laws and regulations. Therefore, the name of an enterprise approved by the industrial and commercial department, even if the font size in the name is the same as that of others, will not constitute trademark infringement. Because, for the enterprise name registration behavior, the registration behavior is not a trademark use behavior stipulated in the Trademark Law, so the behavior itself does not constitute an infringement of the exclusive right to use a registered trademark. However, if another person's trademark is a well-known trademark, or the name of an enterprise uses the same font size as another person's registered trademark irregularly, which will confuse consumers with the source of goods or services. In this case, the use will be suspected of trademark infringement or unfair competition. A trademark is a symbol of products and brands, and a business license is something that a company needs to handle in its business process. If you don't handle it, you are operating without a license. A company may have no trademark, but it cannot have a business license.
