摘　　要：以大为Innojoy专利检索系统收录的全球碳纳米材料在生物医疗领域应用的专利作为数据源,利用定量、定性、可视化分析方法对该领域专利技术生命周期、全球专利布局、申请人、关键技术、技术功效矩阵进行分析。结果显示,碳纳米材料生物医用技术集中在骨组织工程、神经组织、血管支架、药物载体、抗肿瘤、生物成像几大方面,技术进入调整期,但仍然是全球研发热点,并未出现技术衰退的迹象。中国在该领域的专利申请数量排名第一,但是核心专利较少,美国和日本已在全球布局专利,中国仍然主要针对本国市场。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.
