Based on the incoPat patent platform, a statistical analysis was carried out on the patents of strategic emerging industries in Qingdao from 2011 to 2021. The development status of strategic emerging industries in Qingdao was revealed from the trend of patent application authorization and the life cycle, and an in-depth analysis was carried out on the authorized invention patents from multiple dimensions, such as disclosure trend, effectiveness, applicant, technology field, district/city distribution, and transfer license. The results show that the patent development trend of Qingdao's strategic emerging industries has continued to improve in the past 10 years, but the awareness of overseas patent layout needs to be strengthened; Biology, New materials and Energy conservation and environmental protection industries have the largest number of patent applications, but R&D capabilities and innovation quality need to be improved; Universities and research institutes in Qingdao have played an important role in the innovative development and achievements transformation of Qingdao's strategic emerging industries; Laoshan District, Huangdao District and Shinan District have the most active patent innovation activities, but their industrial priorities are different. However, the patent innovation activities between cities and industries in Qingdao are still uneven.
