There are 45 categories of registered trademarks in my country. Among them, there are 34 categories of goods and 11 categories of services, totaling more than 10,000 goods and services. The validity period of a registered trademark is ten years, calculated from the date of approval of registration. You can renew and pay the renewal fee twelve months before the expiration of the validity period. Each renewal is still valid for ten years. There is no limit to the number of renewals. If the application is not submitted within this period, a 6-month extension period may be granted. If the renewal of registration is not submitted within the extension period, the Trademark Office will cancel the registered trademark and make an announcement.
