摘　　要：基于细节改进的专利申请呈现领域通用、方案简单、改进细微的特点,难以快速获得有效对比文件。现提出一种针对此类申请的有效检索策略,将分类号扩展出能够体现出具体细节信息的CPC、FI、FT等分类号,再结合追踪相关中间文献的对比文件,以及关注外文早期文献及日文文献,从而形成一种能够显著提高检索效率与准确性的通用策略,并提供三个实际检索案例对这种检索策略进行阐述。The patent application based on detail improvement presents the characteristics of universal domain,simple scheme and subtle improvement,so it is difficult to quickly obtain effective comparative documents.This paper proposes an effective searching strategy for such applications,which extends the classifi cation number to CPC,FI,FT that can refl ect specifi c details,combines with comparative documents tracing relevant intermediate literature,and pays attention to the early foreign and Japanese literature,so as to form a general strategy that can signifi cantly improve the retrieval effi ciency and accuracy.Three actual retrieval cases are provided to illustrate this searching strategy.
