If you have started a business, the so-called trademark filing is nothing more than wanting to know the trademark you use. Provide several copies (packaging bags) of the trademark logo currently used by your company. Generally, the trademark advertising department is in charge of this matter. They will help you check whether your trademark infringes on the rights of others. If your trademark is not registered, they will guide you to register, guide you to use it correctly, and prepare to help you become bigger and stronger, and apply for famous trademarks and well-known trademarks in the future. The industrial and commercial departments have the obligation to help enterprises register trademarks.
