The starting date of the validity period of a registered trademark is the day when the trademark is registered with the Trademark Office. Since the starting date of the validity period of a registered trademark is also the starting date of the validity period of the trademark-specific tree, and Article 34 of the Trademark Law The validity period of the trademark exclusive right stipulated in paragraph 3 of this Article shall commence from the expiration date of three months from the preliminary approval announcement. Therefore, the starting date of the validity period of a registered trademark should be the same as the starting date of the validity period of the exclusive right to use a registered trademark, starting from the expiration of the three-month period of the preliminary trademark approval announcement, that is, the date of trademark registration. The expiration date of a registered trademark's validity period corresponds to the starting date of the registered trademark's validity period. The same month and day ten years later will be the expiration date of the registered trademark's validity period. The significance of a company's registered trademark is to protect its own corporate interests and establish a corporate image for its company through trademark design. Use trademarks to differentiate yourself from other companies, and use laws to protect your trademarks to prevent cost-promoting behavior from affecting the image of your company's products in the minds of the public. The purpose of clearly stipulating the validity period of trademark registration is for the relevant national departments to conduct more accurate statistics on market enterprises and facilitate other related work. It is also to remind enterprises to pay more attention to trademark registration
