摘要
碳酸钙是一种重要的无机化工产品,广泛应用于塑料、造纸、涂料、橡胶、油墨、牙膏、食品和医药等行业.利用佰腾网作为专利检索数据库,以 2023 年 12 月 31 日为专利检索的截止日期,对碳酸钙产业的授权专利进行全面分析.研究发现,2012-2023 年,碳酸钙产业的专利授权量经历先缓慢增长,再快速增长,后迅速减少的变化趋势;授权专利主要集中在实用新型专利,实用新型专利有 2 843 件,占授权专利总量的 62.73%,而发明专利有 1 689 件,占专利授权总量的 37.27%;技术领域集中在B部(作业和运输)和C部(化学和冶金),B部的专利授权量为 2 570 件,C部的专利授权量为 1 296 件;广西壮族自治区、安徽省、江西省和广东省是专利申请较为活跃的区域,这与碳酸钙资源及其上下游企业的分布密切相关;权利转移类专利、权利质押类专利和许可备案类专利共计 715 件,占专利授权总量的 15.8%,显示出碳酸钙产业专利具有较好的市场应用价值.
Abstract
Calcium carbonate is an important inorganic chemical product widely used in industries such as plastics,papermaking,coatings,rubber,ink,toothpaste,food,and medicine.Taking Baiten as a patent search database,with December 31,2023 as the deadline for patent search,a comprehensive analysis of authorized patents is conducted in the calcium carbonate industry.Research has found that from 2012 to 2023,the patent authorization volume of the calcium carbonate industry experienced a trend of slow growth,rapid growth,and then rapid decrease;the authorized patents are mainly concentrated in utility model patents,with 2 843 utility model patents,accounting for 62.73%of the total authorized patents,and 1 689 invention patents,accounting for 37.27%of the total authorized patents;the technical field is concentrated in Department B(operations and transportation)and Department C(chemistry and metallurgy),with a patent authorization of 2 570 for Department B and 1 296 for Department C;Guangxi Zhuang Autonomous Region,Anhui province,Jiangxi province,and Guangdong province are regions with relatively active patent applications,which is closely related to the distribution of calcium carbonate resources and their upstream and downstream enterprises;a total of 715 patents,including rights transfer patents,rights pledge patents,and license filing patents,account for 15.8%of the total number of patent authorizations,indicating that patents in the calcium carbonate industry have good market application value.
