摘要：背景:生物可降解血管支架是第三代正在发展的血管支架,在治疗血管狭窄方面有巨大的市场价值,全球专利竞争激烈。目的:分析生物可降解血管支架领域专利信息,有助于为中国生物可降解血管支架的技术发展及专利预警提供参考。方法:以法国Orbit数据库为数据来源,通过人工手工筛查,以FAMPAT专利族为基础分析对象,从申请趋势分析、专利布局分析、竞争对手分析3个方面进行分析,并结合技术发展重点和产业化发展情况,筛选出在中国布局的重点专利。结果与结论:美国在该领域处于专利布局领先地位,中国发展迅速;目前研发和专利布局重点为各种支架骨架材料的改良。由于中国的专利布局密集,虽然该领域部分基础专利已过期,中国企事业研发及产业化时仍需进行专利侵权风险排查。
BACKGROUND:Biodegradable vascular stents show great commercial potential as the third generation of stents in the treatment of vascular stenosis,and there is naturally an intense competition in patents.OBJECTIVE:To analyze the patent information of biodegradable vascular scaffolds,which is helpful for better understanding of the development of biodegradable vascular scaffold technology,and provides reference for patent early warning.METHODS:Based on the Orbit patent database,through the manual screening,we conducted an analysis with FAMPAT patent family as analysis object from three aspects-the application trend,patent layout and competitor analysis.In combination with the development of technology and industrialization,important Chinese patent list was also screened.RESULTS AND CONCLUSION:USA is in a leading position in this field,and China develops quickly.There are still a lot of research and patent layout space in the improvement of stent materials.Although some of basic patents have expired,patent infringement risks in China still needs to be investigated due to the intensive patent layout when Chinese enterprises develop their industrialization.
