Abstract: To improve the starting point of new production based on digestion and absorption of existing patented technology,the related technology patents were retrieved according to market information,and the patent strategy to circumvent the basic patent could be determined according to the patent innovation level.The original principle solution model of circumvented patent technology was built with Theory of Invention Problem Solving (TRIZ) method.Through guidance of circumvent patent principles,the research and development objective was identified by combining with the advantage and problems of existing patented technology,and this development goal was clearly defined as an innovative inventive problem.TRIZ method was applied to solve this inventive problem which exploited a new market with competitiveness as well as could be patented technology protection was developed by combining the advantages of the prior patented technology.A kind of completion tool was selected as a case study,and the above innovation process was applied to packer innovation to design around the existing patent and patent related applications.
