摘要:

以大為Innojoy專利檢索系統收錄的全球碳納米材料在生物醫療領域應用的專利作為數據源，利用定量、定性、可視化分析方法對該領域專利技術生命周期、全球專利布局、申請人、關鍵技術、技術功效矩陣進行分析。結果顯示，碳納米材料生物醫用技術集中在骨組織工程、神經組織、血管支架、藥物載體、抗腫瘤、生物成像幾大方面，技術進入調整期，但仍然是全球研發熱點，并未出現技術衰退的跡象。中國在該領域的專利申請數量排名第一，但是核心專利較少，美國和日本已在全球布局專利，中國仍然主要針對本國市場。

Abstract:

Based on the patents from Innojoy index on carbon-based nanomaterials biomedical field and the methods of quantitative analysis, qualitative analysis, visualization analysis, analyses are conducted for life cycle of patented technology, global patent distribution, applicant, key technology and technical efficiency matrix. The analysis results show that carbon nano-materials biomedical technology are focused on tissue engineering, medicine carrier, anti-tumor, and biological imaging. The technology enters the adjustment period, and is still a research focus, without any signs of aging. The number of Chinese applications in this field is the highest, but with very few core patents. The United States and Japan have applied for patents in the whole world. However, China mainly focuses on the domestic market.
