[Objective] To segment Chinese patent claims and fulfill the research needs of patent similarity. [Methods] This paper not only summarizes the segmentation words, the rules of substring segmentation and the rules of domain terms extraction, but also constructs the domain dictionary. The method based on domain dictionaries and rules to segment Chinese patent claims is presented. [Results] The experimental results show that the precision is 90%, the recall-rate is 95%, and F-score is 92%. [Limitations] However, the huge field of dictionaries reduces the efficiency of large-scale segmentation. [Conclusions] This proposed method further improves the effectiveness and efficiency of Chinese patent claims segmentation.
