Abstract:

BACKGROUND: Tissue engineering can achieve tissue and organ regeneration, which is important for regenerative medicine and also reflects the main development direction of regenerative medicine. Patents are the most effective carriers of technical information. The patents in the field of tissue engineering and regenerative medicine are analyzed, which can provide a new research direction in this field from the perspective of information science, and also give some reference for technology development.
OBJECTIVE: To reveal the global technological competition through patent analysis in the field of tissue engineering and regenerative medicine.
METHODS: The global patent applications, invention patent applications and authorizations, and tripartite patent applications in the field of tissue engineering and regenerative medicine in nearly 20 years were analyzed to reveal the status and trends of technology development in this field from the perspectives of the number and quality of patents, regional distribution of patent applicants, patent acceptance countries/regions, patent applicants, inventors, and technical fields. This helps reveal China's technical strength in this field.
RESULTS AND CONCLUSION: In the field of tissue engineering and regenerative medicine, global technique development is active, rapid, and innovative, in particularly in recent 3 years. A number of technological achievements with high market value have been produced. China's tissue engineering and regenerative medicine technology is far beyond that of the United States in terms of development scale and growth rate, and is one of the world's major technical birthplaces. China and the United States are the two most concerned target markets in the tissue engineering and regenerative medicine field, and increasing attention has been paid to the Chinese market. The scale of technological development in the field of tissue engineering and regenerative medicine in many universities in China ranks among the top in the world. Chinese inventors have achieved outstanding research results in the field of tissue engineering and regenerative medicine.
