摘要/Abstract

摘要： 利用PatSnap（智慧芽）数据库分析1985-2017年间大麻相关专利研发态势及技术构成。设计合适的检索式进行检索,检索时要通过更细致的逻辑策略或手工对检索出的专利进行翻译、初筛和清洗。结果显示,大麻相关专利申请总量为28 542件,其中发明专利24 521件,有效专利7 565件、失效专利13 233件。世界范围内专利申请数量排在前三的国家是中国、美国、德国,中国排在前三的省是江苏、浙江、山东。高校的专利申请量较少,绝大部分的发明权掌握在企业。大麻相关的专利保护范围主要集中在医用、食用、纺织、建材等领域。通过专利分析有利于我国及时发现大麻相关领域的技术空白,更科学地开展研发。

Abstract: The objective of this work is to analyze the research trend and technical composition of Cannabis sativa-related patents from 1985 to 2017 in PatSnap database. We designed a suitable query formulation,moreover,translated and screened the retrieved patents manually or by more detailed logic strategy during searching. Results showed that the total number of applied C. sativa-related patents was 28 542,of which 24 521 were invention patents,7 565 were valid patents and 13 233 were invalid patents. The top 3 countries in the world by patent applications were China,the United States,and Germany;while the top 3 provinces in China were Jiangsu,Zhejiang and Shandong. The vast majority of inventions were in the hands of corporations,while universities owned few patent applications. The scope of patent protection related to C. sativa was mainly concentrated in such fields as medical,food,textile,building materials,etc. This analysis is conducive for China to promptly discovering technology blanks in C. sativa-related field and conducting research more scientifically.
