Abstract: Patent is not only the results but also the resources of products innovation.It can help the designer make innovation effectively,if we classify technique knowledge of patent based on innovative demand.The classification of products patent based on the TRIZ can assistant in using technique contradiction addressed in patent to make innovative design.The original Inventive Principles is so abstract that some principles are overlapped.Paper analyzed the 40IPs and grouped them into new 20classes.Patent classification problem is known as multi-label classification problem.Pro-Techniques,CREAX,these two softwares supply patents which explain Inventive Principles in detail.The dataset is used to compare the performance of multi-label classification algorithm:problem transformation and algorithm adaptation.Several measures such as hamming loss,F-measure have been proposed in the literature for the evaluation of multilable classifiers.The result shows Problem Transformation performs more excellent than Algorithm Adaptation using TRIZ patent datasets.

Key words: Patent classification,Inventive principle,TRIZ,Multi-label
