摘　　要：作为衡量专利保护范围的法律依据,专利权利要求是评估专利价值的重要内容,为此本文从权利要求文本出发,提出了基于权利要求语义分析和文档主题生成模型的专利价值评估及应用研究框架,以美国专利局的区块链专利为研究对象,构建专利保护范围测算模型,测算专利价值指标,对高价值区块链专利分布情况、不同技术领域的专利价值分布和不同专利权人的综合竞争地位进行了分析。研究发现,从国家分布来看,前十大专利权人属地主要集中在美国,其余三家分别属于中国、英国、韩国,从区块链专利主题分布来看,数据存储领域的专利价值最高,专利数量最多,网络构架领域专利价值最小。最后结合我国的实际情况提出对策建议。As a legal basis for measuring the scope of patent protection,patent claims are an important part of evaluating the value of a patent.For this reason,starting from the text of claims,this paper proposes a patent value evaluation and application research framework based on the semantic analysis of claims and LDA theme model.Taking the block chain patents in the USPTO patent database as the research object,this paper constructs a calculation model of patent protection scope and measures the patent value index,and analyzes the distribution of high-value block chain patents,the distribution of patent value in different technology fields and the comprehensive competitive status of different patent holders.The study finds that,from the perspective of national distribution,the top 10 patentees are mainly distributed in the United States,while the other three belong to China,the United Kingdom and South Korea.From the distribution of blockchain patents,the data storage field has the highest patent value and the largest number of patents,while the network architecture field has the lowest patent value.Finally,this paper puts forward the countermeasure suggestions according to China’s status quo.
