| Summary: | 碩士 === 國立臺灣科技大學 === 專利研究所 === 104 === This study targets to analyze the global development of wireless power transfer technology, the trend of the development, critical international assignees and classification of patent technologies from different countries. We use data of each patent to analyze the trend, compare the key research area of patent applicants from different nations. After global trend analyzation, we go further to research on wireless power transfer technology in vehicle industry. We provide predictions and suggestions to future technology development through the develop path and historical development of patented technology, which we gained from aspects like general patent trend, critical international assignees, technology-function matrix, technology progress map and etc..
This study is based on data acquired from patent database of United States, Europe, Japan, Korea, China and PCT. We use four research methods and they are data mining, validation, reverse inference and inductive reasoning.
We can reach conclusions after our research, (A)Wireless power transfer technology is a rapid development after 2009, and an explosive growth in 2011. (B)The critical international assignees of Wireless power transfer technology, which leads by Qualcomm, are currently in a technology develop period and will maintain a constant growth. (C)Wireless power transfer technology plays vary roles in different industries on a global scale. European and American institutions focus on the developing of elementary electrical technologies and patent authorization. Japanese focus on vehicle industry and Korean and Chinese focus on communication and smart phone industry. (D)WiTricity and Toyota together use PCT international patent to apply strategy and to lead vehicle related technology development of wireless power transfer. (E)Vehicle related wireless power transfer technology assignees focus on power transfer areas, power transmission, damage control, position control, integrated inductive and conductive electrical charging system consist.
