科技的進步提高了人類生活的水準，並使人類的生命不斷增長，許多先進國家已進入高齡化的社會環境，因此醫療器材產業不斷的發展，根據相關機構的調查報告顯示，全球的醫療市場將會由2012年的3,000億美金成長至2017年的4,344億美金(Global Information, Inc., 2012)，在市場需求的因素驅動下，醫療器材的專利申請數量也不斷上升，根據世界智財組織的資料顯示，在1995年至2008年間，藥學以及醫療科技領域的專利申請成長量相當可觀，僅次於電腦科技、電機與通訊科技類別 (World Intellectual Property Organization, 2011)。專利蘊含了豐富的專業知識與創新價值，但龐大的專利數量與專利文件內的艱深術語，使得專利分析需耗費大量資源，且醫療器材產品的開發過程還須透過臨床試驗才能了解其效用，因此本研究提出結合專利分析與臨床文獻分析的方法，了解未來醫療器材發展的之方向。本研究以專利與臨床文獻的角度分析醫療技術的發展，以知識探勘、本體論、整合分析等方法分析醫療器材專利文件與臨床試驗文獻，本研究首先以文字探勘技術擷取專利文件的重要關鍵字，並建構領域本體論表達專利技術內涵與領域知識，接著分析臨床試驗文獻的關鍵字擴充領域本體論，並進行整合分析了解醫療器材於臨床試驗的效用。本研究以植牙領域為分析案例，希望能了解市場現行發展的趨勢並分析未來可能的市場機會。

The progress of technology increases the average human lifespan. A rise in aging population drives the value of the medical equipment market increases rapidly. According the marketing report, the value of the medical equipment market is US$ 300 billion in 2012, and it is forecasted to reach US$ 430 billion in 2017 (Global Information, Inc., 2012). The rapid growth of medical equipment market indicates that it has great potential for developing. During the period from 1995 to 2008, the volume of patent applications in medical technology increased rapidly worldwide. Computer science, electrical machinery, pharmaceuticals and digital communication also accounted for the large share of total growth (World Intellectual Property Organization, 2011). Patent analysis is useful to understand the trend of technology development. However, the huge volume of patents is hard to analyze effectively and efficiency. In addition, clinical trial on patients must be performed to validate that the new medical equipment is efficacious. The purpose of this study is to analyze emerging medical equipment developments and marketing directions, and a methodology which combines patent analysis with clinical trials is proposed in this study. Knowledge discovering, ontology and meta-analysis are used to extract the useful information from patent documents and clinical trials. This study will use the dental implant technical domain as case study to understand the medical technology market trends.
