Choose a commercial trademark. Commercial trademarks are also called sales trademarks. Sales trademarks refer to words, graphics or their combination marks used by commodity sellers to ensure the quality of the goods they sell. Sales trademarks approved and registered by the state are protected by law. The registrant of the seller's subject matter enjoys the exclusive right to use the trademark. As a modern symbol, sales trademarks bear the intangible assets of enterprises and are the medium of comprehensive information transmission of sales enterprises. In the process of corporate image communication, the sales trademark is the most widely used, the most frequent and the most critical element. The strong overall strength, perfect management mechanism, high-quality products and services of the enterprise are all contained in the logo, which is deeply left in the hearts of the audience through constant stimulation and repeated portrayal.
