根據國內交通部高速公路局統計，因駕駛者沒有主動檢查輪胎的胎壓及胎紋深度的習慣，往往容易造成車輪脫落或爆胎的意外，而引起嚴重的交通事故，這也是國道常見的肇事原因之一；輪胎發生異常狀況是駕駛者最擔心和最難預防的問題之一，而胎壓偵測系統（tire pressure monitoring system; TPMS）的功用即在於協助駕駛者即時監測車輛的胎壓狀況，當胎壓發生異常時，可提醒駕駛者注意，進而達到預防輪胎爆胎的效果。本研究著重在台灣的專利資料庫，針對胎壓偵測系統專利進行檢索並製作專利地圖與技術功效矩陣表（technology/efficacy matrix），了解目前胎壓偵測系統的技術現況與競爭優劣勢；此外，針對個案公司透過競爭者間之專利功效與技術比較、專利技術層次分析及強弱危機綜合分析（SWOT analysis），進一步對個案公司提出在產品可再申請專利，擴大產品的技術保護範圍及專利佈局（patent planning）之策略與建議，可供相關產業廠商參考。

Purpose－Referring to statistical reports from Taiwan area national freeway bureau (MOTC), one of the leading causes of highway accidents is that drivers usually neglected to inspect on tire pressure and tire tread which leads to severe traffic accidents caused by flat tire. The tire-pressure monitoring system (TPMS) is designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. If the unusual situation occurred, the TPMS would remind driver to prevent from flat tire instantly. Design/methodology/approach－The present study proposes an analysis report for recognizing the roadmap of technical development, future trend, and the industry competition of TPMS in Taiwan using patent analysis approach with both patent maps and technology/efficacy matrix from database of Taiwan patent office (TIPO). First, a qualitative study was conducted to explore technical development and the industry competition of TPMS industry. Then, the patent maps associated with technology/efficacy matrix of TPMS products were constructed from the database of TIPO in Taiwan. The SWOT analysis of core technology for developers in TPMSindustry was also examined. Findings－In the proposed report, an illustrative example of the patent planning related to technological innovation in developing the TPMS is used for examining the proposed approach throughout the patent analysis, technology comparison between competitors and SWOT analysis for the case study. Our results also show with recommendations for product developer to apply that the product can be patented that provides a basis for competitive differentiation. Research limitations/implications － This paper focuses on analysis of core technologies for developers of TPMS industry in Taiwan through patent alalysis scheme. Hence, it is suggested that future research can conduct an investigation on competition landscape in the global TPMS market. Practical implications－This paper provides several managerial implications in expanding the scope of products to be protected by applying that the product can be patented, making strategy planning, and pattern planning trends for the case company. Originality/value－This paper is an empricial analysis report that applies SWOT schemey to examine competitive advantage for major developers in the TMPS context. It advances perceptions on the competition landscape of TPMS devekopment in the Taiwan market. The paper concludes with recommendations for product developer in expanding the scope of products to be protected by applying that the product can be patented.
