[Objective] This paper proposes an abstracting model for Chinese patents based on integration strategy (STNLTP), aiming to reduce the duplication and long document dependency issues of the existing automatic abstracting techniques. [Methods] First, we introduced a patent term dictionary, and used the sememe vector based on SAT model to represent traditional Chinese medicine patents. Then, with the help of integration strategy, we utilized the TextRank, Lead4 and NMF models to extract key sentences from the patents. Third, we identified the optimal key sentences with the clustering and redundancy removing. Finally, we processed these optimal key sentences with the pointer-generator network based on Transformer character vector to create the abstracts. [Results] Our new model successfully combined the extractive and generative methods. Compared with the existing RLCPAR model, we improved the evaluation indicators of ROUGE-1, ROUGE-2 and ROUGE-L by 2.00%, 9.73% and 2.35%, respectively. [Limitations] There are still some errors in the new abstracts. [Conclusions] The new STNLTP model could effectively generate Chinese patent abstracts.
