Patent analysis-based technological trend of bone tissue engineering scaffold

Objective To overview the technological development trend of bone tissue engineering scaffold and predict its future research. Methods The status quo, technological trend and materials used in patents of bone tissue engineering scaffold were analyzed in view of patent information in order to predict its future development. Results The number of unclassified patents of bone tissue engineering scaffold was maintained at a high level in recent years and USA took an absolute leading position in research on bone tissue engineering scaffold. No significant mature period of patent technology was developed in our country while a certain mature period was developed in other countries. The materials used in bone tissue engineering scaffold have rapidly entered into a multi-component era from an individualized era. Conclusion Bone tissue engineering scaffold is still a hotspot at home and abroad. Its independent R & D should be strengthened in our country. It is possible for bone tissue engineering scaffold to develop in component structure and function.
