A patent anaIysis of biodegradabIe vascuIar scaffoIds / 中国组织工程研究

ABSTRACT

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.
