Abstract Objective: The purpose is to reveal the research and technology development and patent layout of the 3D bioprinting industry, in order to provide competitive intelligence service for relevant institutions and data support for the development of the industry. Methods: Based on industry research and technology decomposition in the field of 3D bioprinting, we constructed queries to obtain data, and quantitatively analyzed relevant patents in multiple dimensions. Results: The development of 3D bioprinting industry can be divided into gestation period, budding period and high-speed development period; this industry has a low concentration and is in the stage of decentralized competition; applicants mostly choose partners based on geographical factors, and the partners are mostly different types of institutions; Chinese applicants account for nearly 50% of the world’s patent applications, but the average frequency of patent citations of American applicants is still far higher than that of China; American applicants pay more attention to overseas markets. Conclusion: A scale effect has not yet existed in 3D bioprinting industry, so it is necessary to integrate industry resources and build industrial clusters. Both China and the United States have dominant positions in this field, but China urgently needs to strengthen the layout of overseas patents. Taking into account the number and quality of patents, the patent competitiveness of US applicants is still higher than that of China, so China needs to strengthen the cultivation of core patents.
