A trademark is a mark used to distinguish the goods or services of one entity's brand from those of other entities. According to China's Trademark Law, trademarks approved by the China Trademark Office—including commodity trademarks, service trademarks, collective trademarks, and certification trademarks—are granted exclusive rights to trademark holders and protected by law. Well-known trademarks receive additional cross-class legal protection.

  Broadly speaking, trademarks incentivize registrants through recognition and economic benefits, stimulating innovation worldwide. Trademark protection also prevents unfair competitors (e.g., counterfeiters) from using similar marks to market substandard products or services. This system enables skilled and motivated participants to produce and distribute goods/services under equitable conditions, thereby fostering the development of international trade.

  CnOpenData has compiled over 80 million trademark records, including fields such as Applicant Chinese Name (申请人中文名称), Registration Number (注册号), Trademark Name (商标名称), Application Date (申请日期), Preliminary Notice Issue (初审公告期号), Trademark Type (商标类型), Similar Groups (类似群), and International Classification (国际分类号).
