基于产品领域专利布局相似度的专利竞争对手识别
The Identification of Patent Competitors Based on Product-Aimed Patent Portfolio Similarity
摘要
Abstract
[Purpose]Valuing patent portfolios has become a trend and consensus.Therefore,this article proposes a competitor identifica-tion method based on product domain portfolio similarity with the objective of offering intelligence support for enterprises to formulate com-petitive strategies.[Method]Referring to FBS model and TRIZ theory,the product domain patent portfolio analyzing model is construc-ted.Integrating dimension magnitude feature and temporal information embedded dimension semantic feature,mapping method of two-di-mension area and product domain patent portfolio similarity is proposed.Using the smart watch domain an example,an analysis of product domain patent features and competitors of certain enterprises was conducted.[Result/Conclusion]The field experiment suggests that the product aimed patent portfolio model and competitor identification method can help explore the potential competitors in various dimensions and the main competitors in the product domain;the distribution of dimensional similarity and portfolio similarity obtained during the com-petitor identification reflects the differentiation of patents,which can contribute to competitiveness evaluation.关键词
