基于专利信息视角的碳酸钙产业发展趋势分析
Analysis of the Development Trend of Calcium Carbonate Industry from the Perspective of Patent Information
摘要
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.关键词
