Role of trademarks: Trademarks protect trademark registrants by ensuring that they have the exclusive right to indicate goods or services or to license others to use them for remuneration. The term of protection shall be ten years from the date of the announcement of trademark registration, but after the expiration, the trademark may be renewed for an unlimited number of times upon additional payment. The fee for renewal is 25 yuan, and the renewal should be handled within the stipulated renewal period. Trademark protection is generally investigated by the local industrial and commercial bureau. If negotiation fails, it is implemented by the court. In most systems, the court has the right to stop trademark infringement. Broadly speaking, trademarks promote the positive and enterprising spirit of the world by rewarding trademark registrants, enabling them to gain recognition and economic benefits. Trademark protection can also prevent unfair competitors such as counterfeiters from using similar distinctive marks to promote inferior or different products or services. This system enables skilled and enterprising people to produce and sell goods and services under as fair a condition as possible, thus promoting the development of international trade.
