Research On Patent Design Around Innovation Model Based On TRIZ Theory And Problem Recall

With the rapid development of world economic globalization,and under the total framework of WTO,the tariff barriers between the countries around the world are gradually weakened while the technical barriers and corresponding intellectual property barriers are increasing.On the one hand,with its strong scientific research strength,multinational company from western developed countries are building the walls of patent protection,as a result,the domestic enterprise research and development of emerging technologies road closed completely;on the other hand,Some high-tech companies and “patent troll” applied for a large number of patents instead of implementation,and they are up for grabs to obtain huge patent licensing fees.Faced with all kinds of patent offensive strategy,patent design around become the best choice for many patent fence.According to the above problems,this paper studied the patent design around method based on TRIZ and problem recall.Based on the analysis and absorb domestic and foreign research status and achievements,this paper research based on the theory of invention problem solving and back in the patent to avoid design research,aiming to help enterprises to make break through on the patent barriers and solve the problem related to patent troll,furthermore,then can make the small and medium-sized enterprises to lower spending on research and gain development of the technology of comparative advantage,so as to make the enterprises acquire core competitiveness.First of all,introduces and overviews some concepts,methods and general processes related to patent design around.Secondly,define what is problem and recall process.Thirdly,work out two kinds of strategy of patent design around-patent design around based on judging principles and problem recall;The former bridges function analysis,trimming and infringement judging principles,with building function model of target patent,delete or replace some function so as to realize patent design around;The latter transform patent design around to innovation problem by recalling problem which target patent have solved with TRIZ.In conclusion,bring out patent design around and innovation model based on TRIZ and problem recall,Firstly,the patent retrieval and analysis,make sure to avoid the goal of the patent;Secondly,build the function structure and analysis claims of target patent in order to confirm the protection range of the patent;Then,recall the patent problem and determine the type of problem and select the appropriate TRIZ tools to solve problems to get the original scheme according to the different type of problem;Finally,to evaluate the scheme and infringement judging and finish patent design around.Through the top drive casing running auxiliary device and hose pump patent design around,this paper applied and verified patent design around innovation model based on TRIZ theory and problem recall;the method can help enterprise from the prospect ofinnovation quickly and accurately to design around patent according to the actual situation of enterprises.
