天然橡胶专利研发态势分析

采用专利计量方法,对德温特数据库收录天然橡胶专利文献(1963~2015年)进行分析。结果表明:世界天然橡胶专利优先权年跨度为1955~2015年,中国为1986~2015年。世界和中国天然橡胶专利申请量逐年增加;主要申请国为日本、中国、韩国、美国和德国,日本、中国和美国既是专利技术来源国又是市场国;世界天然橡胶专利技术领域研发热点为高分子化合物的组合物、无机物或非高分子有机物填料、轮胎、化学改性等,中国还涉及电缆、导体、绝缘体、涂料和林业领域。

Analysis of the Development of Patent Technology of Natural Rubber

The bibliometric analysis method was used to analyze the natural rubber patent documents collected in the Derwent database during 1963-2015. The results showed that the natural rubber patent priority started from 1955 to 2015 in the worldwide but from1986 to 2015 in China. The number of natural rubber patent applications was increasing year by year in China and the world. The main applicant countries were Japan, China, Korea, the United States and Germany, and Japan, China and the United States were the countries and markets of patented technology. The international hot fields of natural rubber patented technology included compositions of macromolecular compounds, inorganic or non-macromolecular organic filler, tyre, chemical modification and so on. In China, more fields were also listed, such as cables, conductors, insulators, paints and forestry.
