  A trademark is a sign used to distinguish the goods or services of one business operator from those of others. According to China's Trademark Law, registered trademarks approved by the National Intellectual Property Administration (NIPA) include product trademarks, service trademarks, collective trademarks, and certification marks. Trademark registrants enjoy exclusive rights protected by law, with well-known trademarks receiving cross-category legal protection.

  In a broader sense, trademarks incentivize registrants through recognition and economic benefits, thereby fostering innovation and entrepreneurship worldwide. Trademark protection also prevents unfair competitors, such as counterfeiters, from using similar distinctive signs to market inferior or different products/services. This system enables skilled and enterprising individuals to produce and distribute goods/services under fair conditions, ultimately promoting the development of international trade.

  CnOpenData has compiled over 80 million trademark records, containing 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 Approval Announcement Issue Number(初审公告期号), Trademark Type(商标类型), Similar Group(类似群), and International Classification Number(国际分类号).
