从布拉德福定律识别数控机床加工过程自适应控制技术的核心专利

摘要

以Thomson Scientific公司Thomson Innovation数据库收录的2005—2015年全球数控机床加工过程自适应控制技术相关专利为研究对象,利用布拉德福分散定律验证领域核心专利,并对识别出的100件核心专利从专利权主体 角度进行分析.分析结果显示,我国核心专利数量排名世界第一位,但企业作为优先权主体所申请的核心专利数量占总专利数量的36.4%,与美国企业相比,我国企业创新能力建设相对不足,缺乏以核心关键技术为支撑的核心竞争力,同时表明我国大学已经成为我国核心专利申请的重要主体.%Based on patents information of CNC machining process adaptive control collected by Thomson Innovation database from 2005-2015,using the Bradford's law to verify domain core patents, determination of the core effect of this field is more obvious in this paper. Finally it identifies100 core patents, and carries on analysis from their subjects and so on. Results show that the number of core patents in China ranks first in the world, but the number of core patents applied by enterprises is 36.4% of the total number of patents, compared with American Enterprises, the capability of enterprise innovation in our country is relatively insufficient, Lack of core competitiveness supported by core key technologies. In addition, China's universities have become an important part of patent applications.
