基于Citespace文献计量的专利丛林研究现状与热点可视化分析
Visualized analysis of patent thicket research status and hotspots based on Citespace bibliometrics
摘要
Abstract
This paper uses bibliometric and knowledge graph visualization methods to systemati-cally review the current status,research hotspots,and research shortcomings of the patent thicket,and proposes future research directions,with the aim at providing theoretical support for the subsequent research on the patent thicket and helping to accelerate the leapfrog of China's technological innovation efficiency.Based on the relevant literature in the WOS core database from 2003 to 2023,Citespace was used to comprehensively sort out the key information on major researchers,hotspot topics,core journals and important documents in the patent thicket field,thereby clarifying the research hotspots and trends.The study finds that existing studies have ex-tensively explored the connotation,measurement methods,causes,and solution paths of the pa-tent thicket,and that the current research hotspots are mainly concentrated on six core areas:in-novation,R&D,science and technology,intellectual property,market,and in-depth research on the patent thicket phenomenon itself.These aspects jointly constitute the key topics of academic and practical exploration.Future research should strive to deepen the understanding of the conno-tation and evolutionary laws of the patent thicket,build more precise measurement methods for the patent thicket,and explore diverse solution paths to weakening its negative impact on techno-logical innovation.This paper,based on existing literature,proposes three solution paths for the patent thicket from the perspectives of promoting patent cross-licensing,increasing patent ma-intenance costs,and raising the threshold for patent grant examination,to provide intellectual support for addressing the patent thicket and promoting sustainable innovation.关键词
