摘　　要：专利文献侧重于技术创新成果。在技术创新研究中,研发人员有必要对所研究的专题技术实施较为全面的专利信息检索。作者以循环肿瘤细胞(Circulating Tumor Cells,CTC)技术为例,系统阐述专题技术的专利检索策略,主要包括:专利检索工具的选择、关键词的确定、分类号的确定、检索式的设定、查全率与查准率的验证、补充检索。作者通过扩展技术分支检索,提高了检索结果的查全率;通过合理地选取专利分类号,降低了检索结果的噪声。Patent literatures focus on technology innovations. It is necessary for researchers to carry out comprehensive patent retrieval in given technical innovations. This study took the circulating tumor cells（CTC） as an example to illustrate the details of patent retrieval strategy. Retrieval strategy includeed following aspects：patent search tool selection, keyword selection, patent classifications selection, query settings, verification of recall ratio and precision ratio, and result supplementation. In this paper, we improved the recall ratio of results by retrieving the extended branch of technology of the special subject, and we also reduced the noise of the result by selecting patent classification reasonably.
