Many researches examined patent analysis techniques for evaluating the innovation competence of enterprises in a specific industry. Existing studies focus mainly on the analysis of patent number, the number of patent citation, and its scientific link rather than the future trends of technological innovation. Accordingly, the present study generates the patent map based on database of USPTO, EPO, JPO, and TWPAT to discover the opponent's key technologies. Meanwhile, solve the technology innovation problem by incorporating both TRIZ theory and technology trend roadmap. Finally, an illustrative example of the patent planning for technological innovation in developing the product of interactive game is used to demonstrate the proposed approach. Consequently, seven feasible ideas for patent application and three strategies of patent planning were proposed to offer the services aiming to enlarge the scope of claims and provide a complete Intellectual Property (IP) protection.
