Trademarks protect trademark registrants by ensuring that they have the exclusive right to indicate the source of goods or services or to license others to use them for remuneration.

in a broad sense, trademarks can promote the positive and enterprising spirit of the whole 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 the fairest possible conditions, thus promoting the development of international trade.

trademarks are an important part of products and packaging decoration pictures. Trademarks with exquisite design, profound meaning, novelty and outstanding personality can decorate products and beautify packaging well, making consumers happy to buy.
