摘要
随着专利数量的逐年大幅增长,获取有效目标专利的难度也越来越大,专利检索如何实现检准率和检全率的合理平衡成为研究难点。以德温特专利数据库中3G技术专利为检索对象,比较了传统主题检索和手工代码检索两种方式所对应检索及其分析结果的异同,研究表明选择合理的专利检索和分析方法有助于保证分析结果的权威性。
With the yearly increase in the amount of patent data, it is more and more difficult to get target patent effec- tively, because how to keep the balance between the rate of accuracy and the rate of founding actual patents is always the most challenging part for research. Based on patent data of 3G in DII ( Derwent Innovations Index) database, results and differences of traditional theme search and manual code search have been compared. The data analyses close to the actual extent of the situation in two different statistical methods with the same patent data have been done, and the results show that the retrieval and analysis methods used in this paper get more reliable conclusions, which have some practical significance.
